There are a number of effective interventions designed to prevent childhood/adolescent depression. Such interventions tend to comprise screening and the subsequent provision of psychological therapy. However, the cost-effectiveness of routinely providing such interventions at a population level is not known.

By using economic modeling techniques, this study shows that the population cost-effectiveness of such preventive interventions for childhood/adolescent depression is very favorable, although implementation issues, particularly around the acceptability to providers, need to be addressed before widespread adoption.

The evidence base for obesity prevention is extremely limited. Although minority youth are at higher risk of obesity, and early childhood is a critical period for prevention, only 1 program has demonstrated sustained effects on obesity in young minority children.

Among youth at high risk for obesity based on income, minority status, and child behavior problems, early intervention that promotes effective parenting led to meaningful differences in obesity in preadolescence. Early family intervention is an innovative and promising approach. (Read the full article)

Childhood gender nonconformity has been associated with poorer relationships with parents, but it is unknown if childhood gender nonconformity is associated with childhood abuse or with posttraumatic stress disorder.

We identify gender nonconformity before age 11 years as a risk indicator for physical, sexual, and psychological abuse in childhood and lifetime probable posttraumatic stress disorder in youth. (Read the full article)

Previous research on the cost of childhood autism has been restricted primarily to studying direct costs (money outlays) incurred by publicly and privately funded service systems.

This study estimates the economic impact on the family and examines indirect costs to families in the form of parental labor market productivity losses. (Read the full article)

Prenatal methamphetamine exposure has been related to deficits in fetal growth, changes in infant neurobehavior, and fine motor deficits, but little is known about its developmental effects on behavior problems in early childhood.

This is the first prospective study to identify behavior problems associated with prenatal methamphetamine exposure. Mood difficulties and acting-out behavior are increased in exposed children by age 3 years. Early identification and intervention may prevent escalation into delinquency and psychopathology.

Healthcare Effectiveness Data and Information Set (HEDIS) measures are widely used to assess the reliability of pediatric immunization delivery. The extent to which these measures provide accurate ("is this child up-to-date on immunizations?") and useful ("is this child due for catch-up immunizations?") information is unclear.

Overall, HEDIS childhood immunization measures are accurate and useful. Users of HEDIS data should be aware, however, that certain immunizations (eg, hepatitis B, pneumococcal conjugate) and children (eg, those with a single overdue immunization) are more prone to HEDIS misclassification.

Cumulative social factors in childhood have been associated with obesity in adulthood. Little is known regarding the role of accumulation of social stressors and obesity in early life.

Cumulative social adversities were associated with increased odds of early-onset obesity among girls. In addition, those with a higher number of stressors at a single time period had elevated odds for obesity by 5 years of age. (Read the full article)

The hypothesis that maternal prenatal folic acid lowers risk for childhood malignancy in offspring is supported by experimental and epidemiologic evidence, including 2 Canadian ecologic studies that showed inverse associations for some cancer types in the very young.

Examining Surveillance Epidemiology and End Results Program data, a decrease in the incidence of some childhood cancers (Wilms tumor, primitive neuroectodermal tumors) was observed in those <5 years after mandatory US folic acid fortification, with stronger effects detected in infants.

Persistent facial nerve palsy is a well-described neurologic deficit after Lyme neuroborreliosis and occurs in 13% to 20% of children. Other neurologic deficits are less closely described. Nonspecific subjective symptoms are reported as often among patients as controls in previous short-term follow-up studies.

Persistent neurologic deficits, other than facial nerve palsy, were found in 14% of patients, causing impaired fine motor skills, poor balance, or persistent pain. Nonspecific subjective symptoms were reported as often among patients as controls in this long-term follow-up study and should not be considered as sequelae after Lyme neuroborreliosis.

Immature animals exposed to anesthetics display apoptotic neurodegeneration and long-term cognitive deficiencies. In children, studies of cognitive deficits associated with anesthesia exposure have yielded mixed results. No studies to date have used directly administered neuropsychological assessments as outcome measures.

This study examines the association between exposure to anesthesia in children under age 3 and deficits at age 10 by using a battery of directly administered neuropsychological assessments, with deficits found in language and abstract reasoning associated with exposure. (Read the full article)

Early life nutrition may program pubertal timing. Limited evidence suggests breastfeeding is associated with later puberty and childhood milk consumption with earlier puberty; whether these observations are biologically mediated or confounded by socioeconomic position is unclear.

In a developed non-Western setting with little socioeconomic patterning of pubertal timing, neither breastfeeding nor childhood milk consumption was associated with pubertal timing, suggesting nutritional exposures during potentially critical periods may not have long-term effects on rates of maturation.

Childhood obesity is a public health concern. Although determinants of childhood overweight have been identified and their effect sizes have been calculated, prevention as well as treatment have had limited success.

We have calculated the population-based relevance of determinants of childhood overweight by using attributable risks, which can be interpreted as maximum success rates of preventive measures. New concepts were applied to estimate the relative contribution of each risk factor. (Read the full article)

Pediatric obesity is a prevalent public health issue that is associated with medical and physical consequences. Clinic-based interventions for pediatric obesity are effective, but they have limited reach and are costly.

This is the first examination of an empirically informed, scalable treatment of pediatric overweight and obesity delivered in YMCAs. The results indicate that a scalable, community-based pediatric obesity intervention can produce clinically meaningful changes in weight and quality of life. (Read the full article)

Understanding human disease genomics requires large population-based studies. There is lack of standardization, as well as social and ethical concerns surrounding the consent process for pediatric participation in a biorepository.

The study identifies specific barriers to pediatric participation in biorepositories relative to adults, and proposes strategies to improve ethical and responsible participation of pediatric-aged patients in large-scale genomics and biorepository-driven research without significantly increasing research burden for affected families.

Asthma is a common focus of pediatric quality improvement efforts. Various processes of care have been postulated as markers of high-quality pediatric asthma care, but it is not clear which processes correlate with a lower risk of asthma exacerbations.

This study analyzed the correlation of processes of care identifiable through administrative data with asthma exacerbations. The use of 0 vs ≥1 controller medications and the asthma medication ratio had the strongest correlation with asthma exacerbations. (Read the full article)

Cow’s milk consumption has opposite effects on vitamin D and iron levels in children; however, the amount of cow’s milk intake required for sufficient stores of vitamin D and iron is poorly understood, and existing guidelines on consumption are unclear.

Two cups of cow’s milk per day is sufficient to maintain healthy vitamin D and iron stores for most children. Wintertime vitamin D supplementation appears particularly important among children with darker skin pigmentation. (Read the full article)

A small number of studies have found that the introduction of smoke-free legislation has been associated with a reduction in hospital admissions and emergency department visits for asthma.

The implementation of smoke-free legislation in England was associated with an immediate 8.9% reduction in hospitalizations for asthma along with a decrease of 3.4% per year. (Read the full article)

Many studies have identified an association between television viewing and antisocial behavior, although very few have been able to demonstrate a cause-and-effect sequence. The issue of whether excessive television viewing contributes to antisocial behavior remains controversial.

Excessive television viewing during childhood and adolescence was associated with objective and subjective measures of antisocial behavior in adulthood. These associations were not explained by preexisting antisocial tendencies or other potential confounders. Excessive television appears to have long-term psychosocial consequences.

Celiac disease is increasing in several countries and has emerged as a public health problem. Infant feeding has been suggested to affect celiac disease development and/or clinical expression. However, evidence-based complementary feeding strategies are limited.

Significant difference in celiac disease prevalence between 2 cohorts of 12-year-olds indicates an option for disease prevention. The cohorts differed in infant feeding, and our findings suggest that gradual introduction of gluten in small amounts during ongoing breastfeeding is favorable. (Read the full article)

Attention-deficit/hyperactivity disorder (ADHD) has been viewed as a neurodevelopmental disorder, adversely affecting behavior and school performance, with studies suggesting increased risk for poor adult outcomes. However, no prospective studies have examined long-term outcomes of childhood ADHD in an epidemiologic sample.

Our epidemiologic study indicates that adults with childhood ADHD are at increased risk for death from suicide. ADHD persists into adulthood in 29.3% of childhood ADHD cases, and 56.9% have ≥1 psychiatric disorder other than ADHD. (Read the full article)

There are no published prospective studies on the natural course and testicular growth in early childhood of spontaneously descended testes after birth compared with scrotal or surgically treated testes in boys with congenital cryptorchidism.

Data collected from this prospective study on the natural course and growth of the spontaneously descended testes add evidence-based data and recommendations on how to clinically manage boys with congenital cryptorchidism. (Read the full article)

The incidence of childhood and adolescent melanoma has been significantly increasing up to 2004. Risk factors (fair skin, light-colored hair/eyes, female gender, presence of nevi, family history, increased number of sunburns, and exposure to UV radiation) are associated with melanoma.

This study describes incidence trends of melanoma diagnosed between the ages of 0 and 19 years and from 1973 through 2009 by gender, stage and age at diagnosis, primary site, and exposure to UV radiation. (Read the full article)

Cross-sectional studies in children and adults have reported a significant positive association between attention-deficit/hyperactivity disorder (ADHD) and obesity.

This controlled, prospective, follow-up study of boys with ADHD found significantly higher BMI and obesity rates in adulthood, compared with men without childhood ADHD, regardless of socioeconomic status and other lifetime mental disorders. (Read the full article)

Sleep patterns of adult monozygotic twins are more similar than those of dizygotic twins, showing moderate heritability and little effects of environmental influences. There have been very few genetically informative studies of sleep in preschool children and results appear inconsistent.

From previous studies, we investigated daytime and nighttime continuous sleep duration longitudinally. This is the first time that the etiologies of daytime and nighttime continuous sleep duration trajectories were studied in early childhood. (Read the full article)

Excessive weight gain over the first 18 months of life may have consequences for later body size. However, the relationship of weight gain in this period to atherogenic risk factors in later childhood is not well characterized.

Early postnatal weight gain from birth to 18 months is independently associated with childhood overweight and obesity, excess central adiposity, and greater arterial wall thickness at age 8 years. (Read the full article)

There are ethnic differences in lung function, with white people generally having higher values of FVC and FEV₁ than people of South Asian origin, whereas differences in forced expiratory flows are absent or less marked. The underlying reasons are unknown.

Lung function differences were not explained by cultural, socioeconomic, or perinatal factors, nor by environmental exposures or wheezing illness. This suggests that genetic factors are responsible, and supports the use of ethnicity-specific prediction equations for children of South Asian origin. (Read the full article)

About one in five 2-year-olds are overweight, with potential adverse outcomes. Early feeding practices lay the foundation for food preferences and eating behavior and may contribute to future obesity risk. High-quality obesity prevention trials commencing in infancy are rare.

In this large randomized controlled trial, anticipatory guidance on the "when, what, and how" of complementary feeding was associated with increased maternal "protective" feeding practices. Differences in anthropometric indicators were in the expected direction but did not achieve statistical significance. (Read the full article)

Seizure-related death, including sudden death, is a frightening prospect. In part because risk and prevention are poorly understood, neurologists tend to avoid discussions of sudden death with families and young patients.

Most deaths in children with epilepsy are not seizure related. Relative to the population, however, sudden and seizure-related deaths alone double overall mortality. In uncomplicated epilepsy, such deaths occur at rates comparable to individual leading causes of death in young people. (Read the full article)

Health care professionals face problems managing obesity and often fail to follow guidelines for its management in practice. Only a few single-country reports are available describing delivery of primary care to children with obesity.

Nearly all primary pediatric care providers from 4 European countries recognize the importance of obesity in pediatric practice, but only half use BMI clinically, and many lack the confidence and the infrastructure needed for providing care to patients with obesity. (Read the full article)

Physical punishment is associated with a range of Axis I and II mental disorders in adulthood. More research is needed on the possible long-term relationship between physical punishment and physical health.

To our knowledge, this is the first nationally representative examination of harsh physical punishment and physical health. Harsh physical punishment in the absence of child maltreatment is associated with higher odds of cardiovascular disease (borderline significance), arthritis, and obesity. (Read the full article)

Several risk factors for both overweight and obesity in childhood are identifiable during infancy.

A simple risk algorithm can be used to quantify risk of overweight in children. It can be used to help identify at-risk infants in a clinical setting to facilitate targeted intervention. (Read the full article)

The number of overweight and obese children has dramatically increased in recent decades. To combat this trend, information on possible gender-related differences in risk factors of overweight and obesity is critical.

This study examines associations of gender and physiologic and behavior measurements with potential cardiovascular risk. Lunch consumption and screen time were associated with weight; however, other associations with weight differ by gender. This information can be used to tailor future interventions.

At the time of their pediatric medical evaluation, patients with functional abdominal pain (FAP) have higher levels of emotional symptoms compared with youth without FAP. No controlled prospective study has evaluated psychiatric outcomes for FAP patients in adulthood.

This prospective study showed that pediatric FAP was associated with high risk of anxiety disorders in adolescence and young adulthood. Risk was highest if abdominal pain persisted, but was significantly higher than in controls even if pain resolved. (Read the full article)

Hypovitaminosis D is common among children. Although there is prolific biochemical literature linking vitamin D to enteric immunologic function, there is a paucity of prospective data exploring the role of supplementation in prevention of diarrheal illnesses.

In a high-risk population, quarterly supplementation with 100 000 IU of vitamin D₃ did not reduce the risk for first or recurrent diarrheal illnesses in a population of children aged 1 to 29 months in a low-income inner city setting. (Read the full article)

Childhood interstitial lung diseases occur in a variety of clinical contexts and are associated with high morbidity and mortality. Advances in the understanding of disease pathogenesis and use of standardized terminology have facilitated increased case ascertainment.

This study demonstrates that cases of newly described forms of childhood interstitial lung diseases likely occur at all children’s hospitals. With advances in genetic testing and recognition of imaging patterns, a significant portion of cases are identifiable with noninvasive evaluations. (Read the full article)

Pneumonia is the leading cause of death in young children worldwide. Anemia, widely prevalent globally, is not routinely assessed when treating pneumonia. The effect of anemia and high altitude on outcome of pneumonia is not well described.

Anemia at high altitude increases the risk of poor outcome with severe pneumonia. Children with severe pneumonia at high altitude present with more severe hypoxemia and have a longer time to recovery than children at low altitude. (Read the full article)

The etiology of childhood cancers is largely unknown. However, excessive fetal growth has been associated with some childhood cancers. One of the most consistent findings is that high birth weight is associated with an increased risk of childhood leukemia.

Examining large, population-based birth and cancer registry data from 4 Nordic countries, high birth weight was the most strongly associated with risk of many childhood cancers among several measures of fetal growth that have not previously been extensively assessed. (Read the full article)

Psychosocial stress in childhood has been associated with a greater risk of future overweight, although the associations have not always been consistent, the types of psychosocial stressors have often been somewhat extreme, and moderators of the association have rarely been examined.

Experiencing many negative life events in childhood, particularly with chronicity or events that are family health related, increases risk of overweight by age 15 years. Maternal obesity and greater delay of gratification for food each intensify this risk. (Read the full article)

Preterm birth is associated with increased morbidity during childhood. Many studies have focused on outcomes for preterm births before 32 weeks’ gestation, but there are few follow-up data for late preterm infants (34–36 weeks’ gestation).

The risk of respiratory admission during childhood decreased with each successive week in gestation up to 40 to 42 weeks. The increased risk is small for late preterm infants, but the number affected is large and has an impact on health care services. (Read the full article)

Childhood obesity poses a serious threat to human health. Obesity is caused by genetic and environmental factors and linked to type 2 diabetes and cardiovascular disease. Pediatric obesity cohorts aim at understanding early events in the pathophysiology of obesity-related complications.

Cohort subjects are examined at consecutive visits, including measurements of glucose tolerance and hormones regulating nutrient handling (enhanced glucose tolerance tests) and body composition (MRI and bioimpedance). Mechanisms causing obese children to progress to type 2 diabetes are delineated. (Read the full article)

Previous analyses have documented increased health care costs for children with autism spectrum disorders but have not provided comprehensive estimates of the total economic burden.

There are substantial additional costs associated with caring for children with autism spectrum disorders, amounting to >$17 000 per child annually. Costs accrued outside of the health care system account for the majority of the financial burden. (Read the full article)

The first evaluation of the economic impact of all vaccines in the routine US childhood immunization schedule assessed the 2001 schedule (excluding pneumococcal conjugate and influenza vaccines) and documented substantial cost savings over the lifetimes of the cohort of children born in 2001.

This report updates our previous evaluation, and estimates the costs and benefits of vaccinating the cohort of children born in 2009. We include vaccines routinely recommended for children in 2009. (Read the full article)

Many children experience the death of a parent during childhood. The long-term consequences of this life event, including school performance, and the importance of the psychosocial circumstances of the home have not been well elucidated in previous studies.

Both maternal and paternal deaths during childhood were associated with lower grades and school failure. Many of the associations (and especially for death due to external causes) were associated with socioeconomic disadvantage and psychosocial problems in the family. (Read the full article)

Childhood attention-deficit/hyperactivity disorder has been associated with both childhood and adult obesity, whereas treatment with stimulants has been associated with delayed child growth. No longitudinal studies with details about dates of diagnosis, treatment, and duration of stimulant use have been published.

Using electronic health record data, this was the first study to evaluate the independent associations of attention-deficit/hyperactivity disorder diagnosis, stimulant treatment, age at first stimulant use, and duration of stimulant use on longitudinal BMI trajectories throughout childhood and adolescence. (Read the full article)

Inadequate sleep in childhood is associated with poor mental and physical health. Numerous cross-sectional studies reveal associations between television viewing and the presence of a bedroom TV and inadequate sleep in older children and adolescents, but longitudinal research is limited.

More TV viewing, and, among racial/ethnic minority children, bedroom TV, were associated with shorter sleep from infancy to midchildhood. These results raise the possibility that interventions to reduce TV could improve children’s sleep. (Read the full article)

Several studies suggest that excessive media use in early childhood predicts poorer developmental outcomes. It has not been studied whether infants with self-regulation problems, who may be at higher developmental risk, develop excessive media use habits.

This study shows that infants and toddlers with self-regulation difficulties (ie, problems with self-soothing, sleep, emotional regulation, and attention) view more media at 2 years of age, independent of other important confounders. (Read the full article)

Early preventive dental care is cost-effective and can reduce subsequent restorative or emergency visits. Little is known about the factors distinguishing families who receive dental care in early childhood and those who do not.

Our results suggest that among healthy children seen by primary care providers, those most in need of dental care are least likely to receive it. This highlights the importance of promoting early preventive dental care in the primary care setting. (Read the full article)

Reasons for childhood immunization delay include parental intent and barriers such as transportation. To date there has been 1 study of the association of delayed vaccination and seizures, which found measles-mumps-rubella and measles-mumps-rubella-varicella vaccines are both associated with a higher rate of seizures if received after 15 months of age.

Our study found no association between the timing of vaccination and occurrence of seizures in the first year of life. By using different methods, our results support the observation that delaying vaccination with measles-containing vaccines past 15 months of age increases the incidence of postvaccination seizures.

A limited number of studies have identified distinct patterns of child sleep duration, which appear to have implications for health and well-being.

This article identifies distinct patterns of sleep duration during early childhood and demonstrates that these have important implications for health-related quality of life. (Read the full article)

Adverse childhood experiences have been shown to have long-term impacts on health and well-being. However, little work has been done to incorporate the voices of youth in understanding the range of adverse experiences that low-income urban children face.

Study participants cited a broad range of adverse experiences beyond those listed in the initial adverse childhood experience studies. Domains of adverse experiences included family relationships, community stressors, personal victimization, economic hardship, peer relationships, discrimination, school, health, and child welfare/juvenile justice systems.
