Design: Position statement

The WHO Growth Study was initiated in 1997 to follow a cohort of children’s who had been raised in six different countries (Brazil, Ghana, India, Norway, Oman and USA) under recommended nutritional and health practices.  This position statement gives recommendations for physicians on how to properly use the growth charts.
The WHO growth charts are now considered the gold standard for children’s growth and are recommended to physicians to use during well-baby and well-child visits.  The WHO also recommends using calibrated and well-maintained quality equipment to ensure the accuracy of measurements.  According to this report, physicians should be trained to use the new growth charts and should understand the differences between the WHO and CDC growth charts to be prepared to explain them to parents and caregivers. A table of cut-off points for possible growth problems is included and can be seen on the CPS website. III

Growth charts based on internationally sampled children (from Brazil, Ghana, India, Norway, Oman and the USA) with optimal feeding and living conditions (including exclusive breastfeeding for the first 4 to 6 months, no maternal smoking and environments supportive of unconstrained growth).
This study looked at differences in length and height among the populations included in the Multicentre Growth Reference Study (MGRS). There were a total of 8,440 children sampled across all sites; 1,743 in the longitudinal sample and 6,697 enrolled in the cross-sectional sample.  Results showed that variance in growth was 20 times more likely the result of individual variation within a population versus country variation (70% vs. 3%, respectively, of total variance).  Ghana and the USA were representative of the pooled average, while Oman and India tended to have lower values and Brazil and Norway had higher values.

WHO velocity standards for weight are presented for 1-month increments from birth to 12 months and 2- to 6-month increments from birth to 24 months.  An internationally-sampled cohort was prospectively followed to monitor growth patterns. Mothers and newborns visited at home 21 times; 882 of 1,743 (in the longitudinal sample) completely followed-up. This study reports that growth velocity must be interpreted by taking into account attained growth.  One limitation to these methods is the community-based sampling strategy.

Main difference in weight-for-age curves occurs during infancy. CDC sample seems to be generally heavier and WHO standards are taller. According to this review, CDC growth charts have been proven to be inadequate for monitoring the growth of breastfed infants.  The review reports that the WHO standards are a better tool than the CDC 2000 growth charts for monitoring the growth of breastfed infants.  The WHO standards were based on a prospective longitudinal study design while the CDC standards are based on data collected

Design: Review

Results of a review to reevaluate the use of anthropometry at all ages for assessing health, nutrition and social well-being. WHO formed a committee to assess reference data on anthropometric indexes and determine guidelines for use.
The purpose of this paper is to study the evidence of the importance of measuring growth in children. The expert committee convened by the WHO to recommend guidelines and review references. According to this review, for the fetus and newborn infant, it is recommended to use a single, sex-specific multiracial international reference. For infants and children, the expert committee reaffirmed the WHO’s position of using a single international reference. However, they also recommended the replacement or update of the reference due to the limitations of the current one.  For adolescents, the NCHA/WHO reference data were recommended for height-for-age.

Review of the evidence from the literature to make evidence-based recommendations for infant feeding practices.
This policy statement reported that breastfeeding is the optimal method of infant feeding. Out of 15 recommendations by the AAP, the use of human breast milk and breastfeeding are the most important means of infant feeding and achieving good nutrition. This report also recommends that supplements of any kind should not be given to the baby until after 6 months of age. Evidence is based on other policy statements from the American Academy of Pediatrics, American Dietetic Association and a study by Gartner (1994).

Review of evidence supporting the breastfeeding of infants.

There is still some taboo about breastfeeding a baby beyond the age of 6 months in some cultures. The benefits of breastfeeding are numerous.  The ADA recommends that women should breastfeed their children exclusively for 6 months or for 12 months or longer with complimentary food added at 6 months. Evidence comes from prospective cohort studies and policy statements from the AAP.

Twenty-two studies met the inclusion criteria:  11 from developing countries (2 internally-controlled trials from Honduras) and 11 from developed countries (all observational studies). The review showed that infants who are exclusively breastfed for 6 months experience less morbidity from gastrointestinal infection than those who are mixed breastfed starting at 3 to4 months of age. As well, exclusive breastfeeding does not impair growth and can help the mother to lose weight. Exclusive breastfeeding is recommended for the first six months of life in both developed and developing countries.

Subjects: Mother-infant pairs
Design: Systematic review

Performed a literature review using the databases MEDLINE, CINAHL, the Cochrane Library, EMBASE, POPLINE and bibliographies of identified articles.
Twenty-nine studies met the inclusion criteria: 4 RCTs, 20 cohort and 5 cross-sectional studies.  Due to significant heterogeneity in the studies no meta-analysis could be performed. The RCTs showed no difference in weaning between using pacifiers and controls. However, observational studies have shown a strong association. Potential limitations in both these study designs might contribute to the mixed results.  For example in one RCT, there might have been a problem with compliance.

PubMed

Subjects: Healthy term breastfed infants and mothers
Design: Double blinded Randomized Controlled Trial

Participants (N=281) were randomized to 1 of 2 counselling interventions. Each group was counselled by a trained research nurse. The experimental group was different than control as they were counselled to avoid pacifier use and given alternative methods to calm a crying baby.
Early weaning (i.e., within the first 3 months) was compared between groups. Detailed behaviour logs for each infant were maintained describing the frequency and duration of crying and pacifier use at 4, 6, and 9 weeks. Analysis based on random allocation showed no effect between experimental or control groups for either early weaning or cry/fuss behaviour (OR=1.0, 95% CI: 0.6-1.7). When random allocation was ignored a strong observational association was found (RR=1.9).  Follow-up was completed by 91.8% of participants. Data strongly suggest that pacifier use is a marker of breastfeeding difficulties or reduced motivation to breastfeed rather than a cause of early weaning.

Subjects: Preterm infants (<34 weeks)
Design: RCT

Participants were randomized to 1 of 4 groups (cup/no dummy, cup/dummy, bottle/no dummy or bottle/dummy) and used block randomization to stratify infants based on gestational weeks.
Main outcome was the proportion of infants fully breastfeeding by time of discharge. Secondary outcomes included length of hospital stay and prevalence of breastfeeding at 3 and 6 months after discharge. In this study, there was no effect between dummy use and breast feeding at discharge or after 3 and 6 months based on intention to treat analysis. However, there was a significant effect of cup feeding on full breastfeeding at discharge (OR=1.73, 95% CI:1.04-2.88). Also, cup feeds were significantly associated with longer hospital stay.

According to this review, the incidence of ankyloglossia is about 4.8% in the newborn population. They report that restriction of tongue movement must be extreme to interfere with suckling and swallowing. According to this review, evidence suggests that despite newborn or infant ankyloglossia, most babies are able to breastfeed without too much difficulty and that surgical intervention is usually not warranted.

Many populations all over the world suffer from vitamin D deficiency. There was contrasting evidence about the benefits and harms of vitamin D supplementation; however it is now known to be very beneficial. This review reports that vitamin D supplementation for mothers and infants is recommended, especially for high risk groups (i.e., dark pigmented skin, Northern latitudes, whole-body covering). The authors are report that there is some evidence that supports giving breastfeeding mothers higher doses to eliminate direct supplementation to infants.

Review of clinical and observational studies.
Other studies have been done showing potential harmful effects of soy-based formulas because of the presence of phytoestrogens. According to this statement, mothers’ personal preference could be the main reason for use of soy-based formulas. This practice point reports that soy-based formula is not recommended for infants and that the recommendation for soy-based formula for infants with cow’s milk protein allergy (CMPA) or living a vegan lifestyle is no longer valid. One main limitation of studies on CMPA and soy-based formulas is failing to distinguish between IgE- and non-IgE- mediated CMPAs.

Reviewed literature on soy-based formulas for infants. Recommendations are based on a few randomized controlled trials, controlled clinical trials, observational studies and review articles.
According to this review, soy-based formulas do not have adverse effects for normal term infants. However, the review reports that there is no added benefit over cow’s milk (unless the infant has CMPA) and that soy-based formulas should not be used for preterm babies. There is no evidence to support that soy-based formulas prevent atopic diseases or colic. This review reports that soy-based formula should only be used in infants with galactosemia or when a vegetarian diet is preferred.

After 5 years of the study, all children are growing within the normal limits and no adverse effects have been seen. Many countries have recommended reduced use of soy formulas. According to this study, concerns about soy formulas are not supported by convincing data. Most of the evidence against soy formulas is based on RCTs using animal models and cannot be generalized to humans. The follow-up time of this study is adequate to determine any early developmental problems but not longer-term effects.

Design: Clinical report

This statement replaces the AAP statement on hypoallergenic formulas (2000). Reviews the Cochrane Review (above) and other trials to assess nutritional options during pregnancy, lactation and the first year of infancy and any potential relation to the development of atopic disease. Many of the reviewed studies focus on high-risk children (i.e., 1 parent with atopic disease).
According to this report, there is insufficient evidence to support a protective effect of delaying certain foods (e.g. eggs, milk, nuts) after the infant has reached the age of 6 months. Extensively hydrolyzed formulas may be more effective than partially hydrolyzed formulas in the prevention of atopic disease (modest evidence). The statement also notes that there is lack of evidence that antigen avoidance during pregnancy and lactation have a preventative effect on atopic disease. However, they do report that evidence exists for  exclusive breastfeeding for at least 3 months and protection against wheezing in early life. They report that soy formula is not recommended for the purpose of allergy prevention. Many studies had limitations that compromised their conclusions (e.g. no concealment of allocation for RCTs). The power to detect differences was small in many studies.

Review of guidelines for child restraints for transportation in vehicles. Also looked at seating position, seat installation and placement of the child in the seat.
This statement reports that there are 4 stages to child restraints: rear-facing (up to 10kg), forward-facing (up to 22kg), booster (up to 36kg) and finally seat belt (>36kg). Guidelines are based on age but height and weight limitations are more important. The CPS recommends that physicians should counsel parents on the appropriate use of child restraints, as parental misuse of equipment is a common source of harm. Children riding in rear seats in vehicles are 1.7 times less likely to incur a fatal or severe injury than front seat travelers. Recommendations are based on the most current knowledge from the literature and legislation. Evidence is good as the review is based on good methodological case-control studies and RCTs are not ethically feasible.

Data obtained through the Partners for Child Passenger Safety child-focused crash surveillance system and from reported crashes to State Farm Insurance. Driver and parental reports were obtained through phone interviews using a validated survey.

In this study, young children wearing seat belts are more likely to sustain an injury (particularly head injuries) in the event of a car crash than children in child restraint systems (CRS). Very few children 4 to 8 years old were in booster seats (i.e., the appropriate CRS) and were thus not properly restrained. According to this study, the authors report that the use of belt-positioning booster seats is recommended until the child is the appropriate height and weight for seat belt use.

Out of the 5,751 children involved in the accidents, 37% of children 0 to 4 years old were riding in the front seat and only 38% were optimally restrained. The odds ratio (OR) for being involved in a serious car accident is 1.7 (95% CI: 1.6-2.0) times higher for children sitting in the front as compared to the back of a vehicle. The OR for no restraint use was 2.7 (95% CI: 2.4-3.1) compared to restraint use. The investigators report that young children should be properly restrained and seated in the back seat of a vehicle.

The size of the infant being transported by vehicle is an important consideration. According to this report, any necessary medical equipment should be restrained during travel. Risks while traveling include oxygen desaturation, apnea or bradycardia. They report that families should be taught by trained hospital staff to correctly position the car safety seat. As well, proper positioning of the infant in the seat is important. It is suggested in this report that infants be placed in the car seat while still in the hospital and watched for 90 to 120 minutes to help ensure safe travel.

Data was collected from 7 hospitals. Subjects were eligible for the study if they were injured while on a bicycle. Cases sustained head injuries and controls sustained any other injury. Questionnaires were sent out to subjects 7 to14 days after the initial ER visit. 
This study showed that controls were more likely to have been wearing helmets during the crash than cases (56.8% vs. 29.3%). The OR for the association between wearing helmets and sustaining a head injury was 0.31 (95% CI: 0.26-0.37), showing a protective effect of helmets. According to this study, bicycle helmets provide protection to bicyclists of all ages. They reduce the chance of severe head and brain injury. The study suggests that strategies to prevent bicycle injury should focus on the promotion of helmet use through legislation and education.

This is a pre-post study to determine the effect of bike helmet legislation on bicycle-related mortality.  Average numbers of deaths per year and mortality rates per 100 000 person-years were analyzed over a 12 year period from 1991 to 2002. Bicycle helmet legislation was passed in 1995 in Ontario.  Analysis was done on deaths occurring in the age group 1-15 and 16 and over. Data was collected from database of the Office of the Chief Coroner of Ontario.
Overall, there were 362 bicycle-related deaths in the 12 year period of this study (107 in the age group 1-15 years and 255 in the 16 year old and above group).  After legislation, for bicyclists 1 to 15 years old, the average number of deaths per year decreased 52%. This reduction was not seen in the older age group.  Due to the fact that legislation was enforced in the younger age group by fining the parents of the children and not enforced for the older age group, this study reported that  legislation may have a positive effect on reducing the number of bicycle-related deaths.

This case-control study found that the  risk of SIDS is significantly higher when the infant’s last sleep was not in the parental home as well as when he/she is sleeping in the living room compared to the parents’ bedroom. They also found that sleeping prone, bed sharing, sleeping prone on sheepskin and duvets are associated with increased risk of SIDS. This study supports the statement from  the AAP and their recommendations for safe sleeping environments. Novel risk factors include sleeping outside the parents’ home, sleeping in the living room, and sleeping prone on sheepskin (high risk).

This statement provides guidelines for the prevention, diagnosis and management of positional skull deformities in normal healthy infants.
An increased incidence of positional plagiocephaly was observed from 1992 to 1994 which led to the AAP recommendation that all healthy infants be placed on their backs to sleep (i.e., the Back to Sleep campaign). The report states that the  potential risk of plagiocephaly is outweighed by the reduced risk of SIDS from sleeping in the supine position (SIDS rates decreased more than 40% after the initiation of the Back to Sleep campaign). Finally, the authors report that while the infant is awake, there should be supervised tummy time and alternate head positioning during sleep.

Seventy-eight articles, including 9 RCTs, met the inclusion criteria. The review reports that there are potential benefits and harms of swaddling. Healthy infants have less startles, less arousals and longer sleep when swaddled. Swaddling can also benefit preterm infants, decrease crying and does not negatively impact breastfeeding. Potential harms include an increased risk for DDH, SIDS (when infant placed prone), and overheating.  Because of the potential benefits and harms, the authors did not reach conclusions regarding recommendations for swaddling.

Infants were observed during nap times in alternate swaddled and unswaddled (left in a free state) conditions. Behavioural cues determined whether the infant was in REM or quiet sleep (QS).
Outcomes were sighs, startles and full arousals. This study found that swaddling had a significant effect in preventing the progression of arousals in QS. It also decreased spontaneous arousals in QS and increased duration of REM sleep. The study reports that this could potentially help the baby return to sleep without parent intervention and that a safe form of swaddling (allowing for hip flexion and chest wall excursion) may be beneficial.

These results remained stable over time. There was a significant reduction in ADHD symptoms at post-intervention assessment. Intervention gains were maintained for at least a year after the programme’s completion. According to the authors, these results show good potential for the Incredible Years Parenting Program.

Subjects: 2½ to 8 years old
Design: Non-randomized controlled trial

Participants attended IYBPP session. Data was gathered from parents using self-completed questionnaires. Outcomes included pre-test-post-test comparisons and parental satisfaction.

Based on preliminary data (from agency records rather than based on a systematic research design) the results of the pre-test-post-test comparisons are positive. There was significant improvement in test scores at post-test assessment. Effect sizes were in the range of moderate to large. Parents’ responses to the program were positive overall. This study found that there seem to be improvements in scores after a minimum of 9 sessions of the IYBPP. A more rigorous evaluation of the IYBPP is needed.

Children were randomly selected from the Millennium Cohort study and compared to controls. All participants were from low socioeconomic status (SES) families. The authors looked at 14 outcomes.
In this trial, five of the 14 outcomes showed beneficial effects of the SSLP intervention: better social development, more positive social behaviour, greater independence, less negative parenting and a better home-learning environment. Overall, children in the intervention group had more benefits than those in the control group. This study showed the effects of SSLP to be positive with no adverse effects. According to this study, early interventions may improve the life course of many children living in low SES families.

Subjects: 0 to 3 years old
Design: Prospective controlled clinical trial

Children enrolled at birth and followed up until 3 years old. There were 6 randomization sites and 9 quasi-randomized sites (pediatric practices) across the US. The intervention (Healthy Steps Program) included incorporating developmental specialists and enhanced developmental services into pediatric care. The control group was given standard pediatric care.
In total 5565 families were enrolled, 88% completed interviews at 2 to 4 months and 67.2% completed interviews at 30 and 33 months.  There were 4 main domains to determine quality care: effectiveness, patient-centeredness, timeliness and efficiency. Measures included: discussing more than 6 anticipatory guidance topics, being highly satisfied with care provided, receiving timely well-child visits and vaccinations and remaining at the practice for 20 months or longer.  Overall, families that participated in the Healthy Steps Program had greater odds of receiving 4 or more Healthy Steps related services compared to controls. Parenting skills also improved with reduced odds of severe discipline (slapping or spanking with object).  Possible limitations are that parents that completed the 30 to 33 month interview were more socially advantaged than the average enrolled population. This would lead to an overestimation if families lost to follow up would require more intensive interventions.

An electronic review of the literature was performed from 1970 to 1997. Inclusion criteria for studies included: randomized trials, study participants from age 3 to 10, the intervention had to include at least one group-based parent education program and at least one standardized child behaviour outcome measures (parent report or independent observation).
A total of 255 primary studies were retrieved but only 16 studies met the inclusion criteria. Six of the 16 studies used rigorous methods for randomization, whereas several other studies were methodologically flawed. Examples of the types of programs studied were verbal instruction with manual or pamphlet supplementation and Webster-Stratton’s video-tape modelling.  Of the five studies that used parent report to determine effect sizes, all programs showed a positive change in parent perception of child behaviour.  Group-based programs produced better results than individual or self-administered programs.  All studies but one showed long term beneficial effects of programs on children’s behaviour.

There is a negative impact of maternal depression on a child’s cognitive development. The CPS suggests screening for postpartum depression at 2-, 6- and 12-month well-baby care visits. There is fair evidence against routine testing for maternal depression, however, it is strongly suggested that physicians maintain a high degree of clinical suspicion for depression among their patients. The CPS also recommends that patients with symptoms should be referred to psychiatric services.

Review of the evidence for the effectiveness of interventions to prevent child maltreatment. Searched MEDLINE, PSYCINFO, ERIC etc. and consulted experts.
The review reports that the harms of screening for child maltreatment outweigh its potential benefits because of the high rate of false positives. Two RCTs showed reduced child maltreatment with nurse home-visiting interventions from pregnancy to age 2 in high-risk mothers. There is good evidence to recommend nurse home-visits to target high-risk mothers (i.e., less than 19 years old, unmarried and of low socioeconomic status). There is insufficient evidence to recommend education programs for the prevention of sexual abuse.

Subjects: Families
Design: RCT
Enrolled 163 families with a history of at least one child being exposed to physical abuse or neglect. The control group received the standard of care, which included routine follow-up by CPA (child protection agency) caseworkers. The intervention group was treated with the standard of care and a program of home visitation by nurses.

Incidents of physical abuse and neglect were measured by CPA records and hospital records. There was no difference in the recurrence of physical abuse and neglect between the control and intervention groups using CPA records. However, hospital records showed a significantly higher recurrence of physical abuse or neglect among the intervention group. One possible explanation for this is potential ascertainment bias when nurses visited the homes of the intervention group. This study failed to show positive results for an intervention to reduce recurrence of physical abuse or neglect. This study  underlines the importance of initiating prevention strategies against child maltreatment before a pattern of abuse can be established in the family.

Subjects: Mothers with at least one risk factor
Design: RCT

Families were randomized into a control group and an intervention group that had nurse home-visits from the onset of the mother’s pregnancy until the child was 2 years of age. Participants were followed for 15 years. Outcome ascertainment was measured using Child Protective Services official reports.

In the intervention group, 76% of children “survived” until the age of 15 without a CPS report compared to 68% of children in the comparison group. Intervention and control groups were similar until ages 5 to 6. After age 6 the two curves separated and a significant difference was seen in the intervention and comparison group. The control group continued to generate new reports of maltreatment until children were age 15, while there were practically none in the intervention group. This study found that  home-visits have an effect on the onset of child maltreatment. This study also supports the current evidence that the Nurse Family Partnership, a program to reduce child maltreatment in high-risk families can be successful.

The objective of this study was to look at exclusive maternal care versus non parental child care. For children in child-care, type, quality and quantity of child-care were measured.
In this study, higher quality care was related to advanced cognitive, language and pre-academic outcomes at every age (15, 24, 36 and 54 months). Exclusive maternal care was not predictive of any child outcomes. Better socio-emotional and peer outcomes were seen at some ages.  Generally, higher quality care is correlated with better behavioural outcomes and higher income level of the families.  In terms of quantity of child care, the evidence is weak and inconsistent.

The measures for quality of non parental child care were: child-staff ratio, observed group size, caregiver training and caregiver education.  The average child-staff ratio and average group size was higher than recommended at ages 6, 15 and 24 months. At 36 months the ratio and group size were approximately equal to the recommended numbers.  Caregiver training and education were at recommended levels at all 4 ages. Fewer behaviour problems, higher school readiness and language comprehension scores were reported in children that attended classes that met more of the recommended standards.

The AAP reports that it is important for early education and child care to be of high quality. Given its limited availability, the AAP recommends that physicians should work with parents and the community to facilitate access to the best child care possible. Evidence shows that high quality (i.e., developmentally sound and emotionally supportive) early education has a positive effect on both the child and their family. The AAP recommends that physicians are encouraged to ask families about their child care situation.

Using data from the 1997 birth cohort from April and May in Hong Kong, investigators followed up with infants and parents at 3, 9 and 18 months.  Based on self-reported smoking data, families were classified as no exposure, smoking more than 3 meters and less than 3 meters away from the child.
In this study, second-hand smoke exposure less than 3 meters away from the infant was associated with the highest risk of admission for infectious illness (hazard ratio 1.14, 95% CI: 1.00-1.31). This association was strongest for infants 0 to 6 months years old. Exposure of infants to second-hand smoke within 3 meters increased their risk of serious illness, both respiratory and other infections. This study also showed that young infants (<6 months)  as well as low birth weight and preterm infants are at high risk.

According to this report, children <2 years old are most vulnerable to the adverse side-effects of OTCs. Lower weight children aged 2 to 6 years old are also at risk. Younger children are less able to communicate any adverse side-effects therefore are at heightened risk. According to Health Canada, certain cough and cold medicines should not be used in children <6 years old. Reports of misuse, overdosing and serious side-effects prompted the Health Canada advisory.

Subjects: 6 months to 6 years old
Design: RCT

Participants from primary care settings and households in England were randomized to 1 of 3 intervention arms: paracetamol alone, ibuprofen alone or a combination of both.
The outcome measures were 1) the amount of time without fever in the first 4 hours after the first dose was given and 2) the proportion of children not experiencing discomfort (i.e., normal on the discomfort scale) after 48 hours. For amount of time with fever in the first 4 hours, the combination intervention arm was more effective than paracetamol alone and as good as ibuprofen. Combination therapy also cleared fever faster than paracetamol alone but showed no difference compared to ibuprofen alone. No difference was found for discomfort or other symptoms. The authors report that physicians should recommend ibuprofen for fever reduction.

Subjects: 6 months to 10 years old
Design: RCT

Three arm, open label randomized trial in a Children’s ED, London, England. Participants received suspensions of paracetamol (15 mg/kg), ibuprofen (5 mg/kg) or both.
Using an intention-to-treat analysis, a significant difference between the 3 groups was found (p=0.023). There was a difference between the combined and paracetamol treatments, but not between combined and ibuprofen treatments. The combined treatment was better at reducing fever than paracetamol alone.  Although the difference was significant, the study was carried out in a paediatric emergency room therefore only one third of the patients had their temperature recorded post-dose. This RCT reports that there is not enough benefit to warrant routine use of combined therapy for rapid fever reduction.

Design: Meta-analysis

Searched electronic databases (MEDLINE, EMBASE, Cochrane Library, Biological Abstracts etc). Studies had to include random allocation to treatment arms and have blinded participants.
Seventeen studies met the inclusion criteria. Primary outcomes were pain, fever and safety. Both ibuprofen and acetaminophen were equally effective for pain. Ibuprofen was superior for fever relief. There was no evidence that the drugs differed in safety. There was no difference between ibuprofen and acetaminophen for pain and safety; however, ibuprofen was superior for fever reduction, especially at 4 and 6 hours after treatment. There is no clear preference as both treatments are more effective than placebo.

Double-blinded randomized controlled trial with three parallel groups. Patients were randomized to 3 intervention groups: acetaminophen, ibuprofen and an alternating regime of both.
Outcome measures included temperature, stress score, number of days absent from day care or work. There was a significant difference between combined and acetaminophen, as well as combined and ibuprofen treatments (all differences were statistically significant P<.001) but no difference between the mono-therapies. The alternating regimen was more effective at reducing temperature than either mono-therapy. One limitation of the combination therapy is due to the different doses of each treatment, there is potential for parental confusion and possible adverse events.

Design: Systematic review

Performed a search of electronic databases MEDLINE, PreMedline, CancerLit and LILACS for studies On non-Hodgkin lymphoma, leukemia and 8 solid-tumour cancers published between 1992 and 2003. Studies were reviewed by 2 trained reviewers and rated on methodologic quality according to a 5-page assessment tool. Studies rates below a score of 4 out of 7 were excluded.

Eighty-three studies were found. Most studies on non-Hodgkin lymphoma and leukemia showed a positive association with pesticide exposure. There was an association between kidney cancer in children and parents with occupational exposure. The 8 solid-tumour cancers included: brain, breast, kidney, lung, ovarian, pancreatic, prostate and stomach cancer. This review of evidence shows an association between pesticide exposure and cancer, particularly brain, prostate, kidney and non-Hodgkin lymphoma and leukemia. Children had an increased risk of cancer during critical periods of exposure (both prenatal and postnatal) and with parental exposure at work. The authors recommend reduced exposure to all pesticides.

Used the study population for the Northern California Childhood Leukemia Study (NCCLS). Matched cases with controls from the population birth registry. Exposure was the use of pest control services from 1 year before birth to 3 years after birth.
In this study, professional pesticide use was associated with leukemia (OR=2.8, 95% CI 1.4-5.7). The highest risk of childhood leukemia was exposure to pesticides during pregnancy and also, early life exposure had higher risk than exposure in later life. Indoor pesticides were more harmful than outdoor pesticides. Also, there was higher risk with greater frequency of exposure. This study showed that the timing, location and frequency of exposure to pesticides may be associated with  the risk of developing leukemia.

Data from the Children’s Cancer Group. Used matched, randomly selected, regional population controls. Assessed pesticide exposure through telephone interviews with mothers.

This study found a significant association between the risk of non-Hodgkin lymphoma (NHL) and increased frequency of pesticide use in the home. Use of professional extermination services and postnatal exposure were also significant predictors of NHL. However, due to some limitations of the study (self-report of pesticide exposure can lead to potential for recall bias), no causal trend can be determined and further investigation is warranted.

Subjects: Children
Design: Review

Reviewed literature from searches of MEDLINE and Web of Science database using key words: Canada, child, lead poisoning, blood lead, and paediatrician.
There has been limited surveillance for blood lead levels among children and little research on the effects of low-level lead poisoning. Neurodevelopmental damage has been seen in children with blood lead levels lower than the current standards (i.e., 0.48 μmol/L). The authors conclude that the current regulations might be inadequate to protect children against lead poisoning. The review reports that physicians should be aware of screening tools for use in high-risk children and inform parents about the symptoms of lead poisoning.

Design: Prospective cohort study

Used data from the Third National Health and Nutrition Examination Survey (NHANES III). Assessed relationship between blood lead concentrations and performance on cognitive tests (arithmetic, reading, nonverbal reasoning, and short-term memory)

After performing a multivariate analysis to control for potential confounders, there was an inverse relationship between blood lead concentration and scores on the 4 cognitive tests. Children were dichotomized to two groups for comparison: those with blood levels <5 and those with blood levels of 5 and over. Children with blood levels <5 µg/dL had decreased scores in reading and math. This study suggests that cognitive deficits are associated with blood lead concentrations <5 µg/dL. These findings are important given that current standards are set at 10 µg/dL.

Subjects: Infants
Design: Prospective cohort study
(N=294)

Healthy mother –infants pairs were recruited from Mexican maternity hospitals.  Infants were included if their blood lead levels at both 12 and 24 months of age were <10 µg/dL. Outcome measures were Bayley Scales of Infant Development II, specifically: 1) the Mental Development Index (MDI) and 2) the Psychomotor Development Index (PDI) at 12 and 24 months.
At 12 months, there was no significant association between MDI and PDI scores and blood lead levels. At 24 months, blood lead levels were inversely associated with both MDI and PDI scores Blood lead levels at 12 months were inversely associated with PDI scores at 24 months. These relationships were not altered by adjustment for cord lead blood levels or 12-month MDI and PDI scores.  Results of this study suggest that exposure to lead, even in the range of <10 µg/dL (the current screening guideline), may adversely impact the neurodevelopment of infants in a dose-dependent manner.

Many studies have shown adverse effects, such as cognitive deficits and behavioural problems, in children with “low” blood lead levels. According to this review, there is no level of lead exposure that is considered to be safe. The authors highlight that in order to prevent exposure it is important to keep parents of young children informed of all sources of lead in their child’s environment.

Low-income families were randomized to intervention or control groups. At baseline. The intervention group received children’s books, educational materials and advice from pediatricians about sharing books with children.  Follow-up included family interviews and child language testing. A Child-Centered Literacy Orientation was defined as a stated enjoyment of reading and/or report of usual reading together at bedtime.
At follow-up (an average of 3.4 well-child visits later; mean age 18.4 months), there was a 40% increase in Child-Centered Literacy Orientation among the intervention families compared to 16% among controls. In older intervention toddlers, receptive and expressive vocabulary scores were higher, but not for younger intervention toddlers. When reading aloud was added to a multivariate analysis, the effect of the intervention was no longer evident.  The authors concluded that this simple intervention changed parental attitudes, and as they increasingly read to their children older toddlers in particular experienced enhanced language development.

Subjects: 2 to 5.9 years old
Design: Cross-sectional survey

Two federally funded health centres were used as the two sites of comparison. Subjects attending clinic A had a 3 year Reach Out and Read (ROR) intervention while attendants of clinic B had no ROR exposure. The ROR program included counselling parents about reading to children and parents received an age-appropriate book at each well-child visit.
The sample size for this study was 200 parent/child pairs with mean age of children of 3.8 years.  The outcome measures were expressive and receptive one word picture vocabulary tests, a home literacy orientation scale created by the authors, and the STIMQ-READ subscale.  Comparing English-speaking children, there was a statistically significant difference (p=0.01) between ROR-exposed children and controls.  A positive association between the Reach Out and Read program and better receptive vocabulary scores were reported. Higher scores were also found on measures of home reading activities. Limitations of this study include the cross-sectional design’s inability to determine a causal relationship and parental reports of home reading activity may have lead to a degree of recall bias.

19 clinical sites were included in 10 states. At each site a convenience sample was interviewed before the implementation of the Reach Out and Read (ROR) program, which served as the control group. A separate convenience sample was interviewed after the program which served as the experimental group.
The total sample size was 1,647 subjects.  Main outcome measures were parental interviews based on questions from validated questionnaires about their attitudes and practices related to reading out loud.  There was a significant association (p < 0.001) between exposure to ROR and reading aloud as a favourite parenting activity, at bedtime, 3 or more days a week and ownership of >= 10 picture books.  Limitations to this study are taking a convenience sample of subjects and sites that were different before and after.  This can limit the ability to generalize the findings to the population and can introduce selection bias. There is also possibility for social desirability bias from parents’ answers to the questions.

Subjects: Children
Design: Clinical practice guidelines

Guidelines were generated based on available medical literature. Performed computerized search of PubMed database with keywords: sleep apnea syndrome, apnea, sleep disorders, snoring, polysomnography, airway obstruction, adenoidectomy, tonsillectomy (adverse effects mortality), and sleep-disordered breathing.
There were very few RCTs. The AAP recommendations include the following: 1) all children should be screened for snoring; 2) complex or high-risk patients should be referred to a specialist; 3) thorough diagnostic evaluation should be performed; 4) adenotonsillectomy is the first line of treatment for children with OSAS; 5) all surgical patients should receive post-operative re-evaluation to determine whether additional treatment is necessary.

For parents and caregivers with questions about vaccines

From Blaine review: “This is a well-written and informative book, with an appealing cover design and children’s drawings throughout. A clear introduction delivers what is promised. In the disease-specific chapters, credible information is provided, often in the form of statistically accurate and visually convincing table and graphs. Vaccine histories, side effects and associated risks are discussed in detail. Primary health care providers would do well to have this information at their fingertips.” Note that a new edition has been published since this review.

The objective of this report is to help pediatricians understand the various reasons why parents might refuse a vaccine. As well, it gives them appropriate guidelines on how to deal with parents who refuse immunizations for their children.
Three issues are discussed in this report: 1) if the parents are withholding medical care this constitutes medical neglect and child services have to be called; 2) if not immunizing poses harm to the community, this becomes a public health issue; and 3) how the physician should respond to a refusing parent. Due to the high rates of immunization in most communities and low prevalence of vaccine-preventable disease, the authors report that many unimmunized children can be covered by herd immunity. The report highlights that physicians should counsel parents on the benefits of vaccines and address their concerns.

Subjects: Infants and children
Design: Position Statement

Review and recommendations for physicians about the new quadrivalent meningococcal conjugate vaccine for serogroups A, C, Y and W135 (MCV4).

The CPS recommends that 1) physicians should encourage and promote immunization programs for infants starting at two months of age; 2)  children who are at increased risk should be given a meningococcal C conjugate vaccine during infancy and then a MCV4 booster at 2 years of age; 3)the MCV4 vaccine may also be used for HIV-positive children at two years of age and older; 4)finally, at 12 years old a booster dose of MCV4 or the meningococcal C conjugate vaccine should be offered.

Subjects: Infants and children
Design: Advisory Committee Statement (ACS)

The NACI provided the Public Health Agency of Canada with ongoing medical, scientific and public health advice relating to immunization. These recommendations are based on the best current available scientific knowledge.
Studies have shown that effectiveness of the meningococcal C conjugate vaccine decreases after 1 year following the completion of the infant vaccination series.  Therefore, the NACI recommends a booster shot in the second year of life, if the infant received their first shot at less than 1 year old.

Table 1. Recommendations Grades for Specific Clinical Preventive Actions
A There is good evidence to recommend the clinical preventive action.
B There is fair evidence to recommend the clinical preventive action.
C The existing evidence is conflicting and does not allow to make a recommendation for or against use of the clinical preventive action; however, other factors may influence decision making.
D There is fair evidence to recommend against the clinical preventive action.
E There is good evidence to recommend against the clinical preventive action.
I There is insufficient evidence (in quantity or quality) to make a recommendation; however, other factors may influence decision making.
The CTF recognizes that in many cases patient specific factors need to be considered and discussed, such as the value the patient places on the clinical preventive action; its possible positive and negative outcomes; and the context and /or personal circumstances of the patient (medical and other). In certain circumstances where the evidence is complex, conflicting or insufficient, a more detailed discussion may be required.
Table 2. Levels of Evidence - Research Design Rating
I Evidence obtained from at least one properly randomized trial.
II-1 Evidence obtained from a well-designed, controlled trial without randomization.
II-2 Evidence obtained from a well-designed cohort or case-controlled analytic studeis, preferably from more than one centre or research group.
II-3 Evidence obtained from comparisons between times and places, with or without the intervention; dramatic results in uncontrolled experiments could also be included in this category.
III Opinions of respected authorities, based on clinical experience, descriptive studies or reports of expert committees.
Table 3. Levels of Evidence - Quality (Internal Validity) Rating (see Harris et al., 2001)
Good A study (including meta-analyses or systematic reviews) that meets all design-specific criteria* well.
Fair A study (including meta-analyses or systematic reviews) that does not meet (or it is not clear that it meets) at least one design-specific criterion* but has no known "fatal flaw".
Poor A study (including meta-analyses or systematic reviews) that has at least one design-specific* "fatal flaw", or an accumulation of lesser flaws to the extent that the results of the study are not deemed able to inform recommendations.
  *General design-specific criteria are outlined in Harris et al., 2001.
