Nationally representative surveys provide insight into overall childhood obesity trends and disparities but do not identify patterns specific to individual states. School-based surveillance is recommended, but it is unclear whether surveillance is helping to identify children at greatest risk.

This study includes 3 consecutive years of surveillance findings to describe within-state spatial and socioeconomic disparities in obesity among elementary-aged children. Implications for states using and considering school-based surveillance to plan preventive interventions are considered. (Read the full article)

Data from several states that have implemented protective eyewear mandates at the scholastic level have shown a substantial reduction in eye injuries. However, there are no studies that critically evaluate the effectiveness of protective eyewear in girls’ field hockey.

Data collected from regional/national high school sports injury surveillance databases by certified athletic trainers has resulted in the largest prospective national study examining the effectiveness of mandated protective eyewear in reducing head, eye/orbital, concussive, and facial injuries performed to date.

Drowning is a leading cause of death for children in low- and middle-income countries. However, few childhood mortality reduction programs target drowning because of a lack of evidence on costs and effectiveness of these interventions.

This study presents the cost-effectiveness results of a low-cost injury and drowning prevention program in Bangladesh. We show that child care centers and swimming lessons are highly cost-effective interventions that could be scaled to other countries. (Read the full article)

It has been suggested that maternal immune activation during pregnancy is associated with cardinal behaviors of autism in the offspring. Epidemiologic studies have yielded conflicting results concerning the association between any infection during pregnancy and the development of autism.

This population-based cohort study investigated the association between specific common infectious diseases, febrile episodes, or use of antibiotics during pregnancy by using maternal population-based self-reported data. (Read the full article)

Several studies have reported inverse associations between fish consumption during pregnancy or later childhood and asthma prevalence. However, because fish can also be highly allergenic, the optimal timing of introduction of fish and the adequate amount in infancy remains unclear.

Introduction of fish between 6 and 12 months but not fish consumption afterward is associated with a lower risk of wheezing whereas no introduction of fish or introduction between 0 and 6 months of life increases the risk of wheezing. (Read the full article)

Stressful events adversely affect the immune system, particularly the natural killer (NK) cells. Infants in the NICUs are exposed to stressful stimuli. The effect of massage therapy on the immune system of preterm infants has not been investigated.

This randomized placebo-controlled study found daily massage performed in stable preterm infants for a minimum of 5 days was associated with an increase in NK cell cytotoxicity despite lower absolute NK cell numbers compared with controls. (Read the full article)

Previous studies have revealed misconceptions among pediatric patients, their families, and athletic coaches surrounding concussion. Little is known about pediatric primary care and emergency medicine providers’ attitudes and beliefs about diagnosis and management of this mild traumatic brain injury.

Although pediatric primary care and emergency medicine providers regularly care for concussion patients and value their role in management, they may not have adequate training or infrastructure to systematically diagnose and manage these patients. (Read the full article)

In adolescents with eating disorders, percent expected body weight (EBW) is used for diagnosis and to make clinical decisions. The assumption is that the weight-for-stature (WFS) and BMI methods of determining EBW are equivalent, but that may not be true.

This study demonstrates that EBW_WFS is ~3.5% higher than EBW_BMI. Differences are most pronounced at extremes of height. Compared with the EBW_WFS method, sensitivity of EBW_BMI to detect those <75% EBW is low. (Read the full article)

In a previous randomized trial, infants from a low-resource country exclusively breastfed for 6 months had lower iron stores at 6 months compared with breastfeeding infants receiving solid foods. Randomized trials of exclusive breastfeeding in high-income countries are lacking.

In a high-income country, infants who receive complementary foods in addition to breast milk from 4 months of age had higher iron stores at 6 months compared with those exclusively breastfed for 6 months. (Read the full article)

Information is limited on adoption of fully functional electronic health records (EHRs) in office-based pediatric practices, such as rates of adoption, barriers to adoption, and features that pediatricians choose.

A nationwide survey of members of the AAP in 2009 found that pediatric adoption of fully functional EHRs lags general adoption. Barriers include financial and productivity concerns, but pediatricians are also concerned about finding systems that meet their specific needs. (Read the full article)

Disparities in vaccination coverage between American Indian/Alaska Native and white children previously existed between 2001 and 2004 but were not present in 2005.

This study updates a previous study by analyzing data through 2010 and found that these gains have been maintained. (Read the full article)

Children born small for gestational age (SGA) have increased risk of perinatal morbidity and mortality, neonatal death, and cerebral palsy (CP). Causes of SGA, such as congenital malformations, intrauterine infections, and preeclampsia, are also risk factors for the same outcomes.

In 90% of singletons born SGA, CP is apparently of prenatal origin. Low proportions of intrapartum events leading to CP could not be fully explained by a higher neonatal mortality rate in SGA than in non-SGA children. (Read the full article)

Emphasis on muscularity has increased in recent decades. Identifying adolescent populations at risk for unhealthy muscle-enhancing behaviors is of considerable importance, yet recent research in the United States is limited in terms of sample diversity and behaviors of interest.

Muscle-enhancing behaviors were common for both boys and girls, and rates were higher than reported previously. Adolescents in high school, of Asian background, in overweight/obese BMI categories, and involved in sports reported significantly greater use than other youth. (Read the full article)

Doxorubicin therapy, effective against many malignancies, is limited by cardiotoxicity. Continuous-infusion doxorubicin, compared with bolus-infusion, reduces early cardiotoxicity in adults. Its effectiveness in reducing late cardiotoxicity in children remains uncertain.

This multicenter randomized trial assessed whether continuous-infusion of doxorubicin in pediatric patients provides long-term cardioprotection or improvement in event-free survival over bolus-infusion in acute lymphoblastic leukemia. Continuous-infusion of doxorubicin provided no cardioprotection or improvement in event-free survival. (Read the full article)

The impact of relative age at school entry on academic progress and the risk of being diagnosed with ADHD remains controversial. Stimulants are widely used as a therapeutic option for ADHD in the United States and increasingly in Europe.

Relative age among classmates affects academic performance among boys and girls into puberty, as well as children’s risk of being prescribed stimulants for ADHD. This should be taken into account when evaluating children’s performance and behavior in school to prevent unnecessary stimulant prescribing. (Read the full article)

Adolescents have high placebo response rates in depression treatment trials. Screening for depression will likely detect youth with a broad range of symptom severity, including some who would benefit from watchful waiting but might not require active treatment.

The strongest predictors of symptom persistence are depressive symptom severity at presentation and continued symptoms on repeat screening 6 weeks later. These results provide important information for the development of postscreening management protocols in the primary care setting. (Read the full article)

Neonatal respiratory distress syndrome is the most common respiratory cause of mortality and morbidity among US infants aged <1 year. Although neonatal respiratory distress syndrome is a heritable disorder, common genetic variants do not fully explain disease heritability.

Single ABCA3 mutations are overrepresented among term and late preterm (≥34 weeks’ gestation) European-descent infants with RDS. Although ABCA3 mutations are individually rare, they are collectively common in the European- and African-descent general population, present in ~4% of individuals. (Read the full article)

Some children with gastroenteritis fail to respond to oral rehydration. Subsequent interventions are dictated by regional preference. In North America, nasogastric rehydration is rarely administered. Caregiver and health care providers’ perspectives regarding its use have not been described previously.

Both caregivers and health care providers would select intravenous rehydration instead of nasogastric rehydration when oral rehydration fails. Greater knowledge mobilization efforts will be required for nasogastric rehydration to be adopted into clinical practice. (Read the full article)

High doses of radiation have been linked to cancer induction in irradiated populations such as atomic bomb survivors. Medical imaging directs significant radiation doses to human tissues. Epidemiological studies have demonstrated that children are more sensitive to radiation than adults.

The link between cancer induction from moderate radiation doses such as diagnostic imaging is controversial. This study uses Food and Drug Administration–accepted formulas to calculate theoretical risk of breast cancer induction in female pediatric trauma patients receiving diagnostic imaging of the thoracic spine.

Delayed meconium passage impairs gastrointestinal function in premature infants. No intervention has been identified that accelerates meconium passage sufficiently. Gastrografin is an osmotic contrast agent used for radiologic examination of the bowel or for conservative treatment of uncomplicated meconium ileus.

Gastrografin did not accelerate complete meconium evacuation but stimulated gastrointestinal motility in a randomized, placebo-controlled trial in premature infants. Application shortened the time to full enteral feedings and hospital stay but was associated with necrotizing enterocolitis as a possible adverse event. (Read the full article)

Adolescent physical fighting is an important public health concern with known social origins. However, existing international studies of adolescent fighting provide little evidence about its prevalence, trends over time, or possible socioeconomic determinants.

We studied frequent physical fighting among 494 874 adolescents in 30 countries over an 8-year period. Physical fighting declined in most countries. National measures of absolute wealth but not socioeconomic inequalities related to risk of frequent physical fighting. (Read the full article)

Antimicrobials are a medication class frequently implicated in pediatric adverse drug reactions (ADRs). Trimethoprim-sulfamethoxazole (TMP-SMX) is long recognized as a contributor to the burden of these undesired and unpredictable events.

TMP-SMX ADRs increased from 2000 to 2009, with the majority of children taking the antibiotic for skin and soft tissue infections. The significant increase in TMP-SMX prescribing for these infections may result in a continued increase of associated ADRs. (Read the full article)

Youth exposure to retail tobacco advertisements and displays is associated with smoking initiation. The Family Smoking Prevention and Tobacco Control Act of 2009 gives states and local governments legal authority to regulate the time, place, and manner of tobacco advertising.

This is the first experimental study using a virtual store environment to provide evidence that a policy banning tobacco product displays at the point of sale may deter youth from attempting to purchase tobacco products at retail stores. (Read the full article)

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)

Knowledge is limited regarding the epidemiology of persistent pulmonary hypertension of the newborn (PPHN). Previous work has implicated a host of perinatal risk factors and a few antenatal antecedents of PPHN, including maternal consumption during pregnancy of nonsteroidal antiinflammatory medications.

In contrast to results of previous studies, we found no association between PPHN and maternal consumption during late pregnancy of nonsteroidal antiinflammatory drugs in general or ibuprofen in particular. (Read the full article)

Very low birth weight (VLBW; <1500 g) subjects show lower scores in performance-based tests of executive functioning (EF) than control subjects up to young adulthood.

VLBW adults’ perceptions of their EF in everyday life are very similar to those of term-born adults. Parental evaluation of VLBW/small-for-gestational-age adults’ EF is more negative than adults’ self-reports. (Read the full article)

Obesity is a risk factor for failure to initiate breastfeeding, formula supplementation, and short breastfeeding duration. There is a need for interventions that can improve the breastfeeding outcomes of overweight and obese women.

Breastfeeding peer counseling targeting overweight/obese women did not affect exclusive breastfeeding rates or breastfeeding continuation beyond 2 weeks. However, the intervention was associated with improvements in early breastfeeding intensity and fewer infant hospitalizations in the first 6 months after birth. (Read the full article)

National asthma treatment guidelines include the recommendation that all asthma patients receive a written asthma action plan. No previous study has sought to examine the readability, suitability, and content of asthma action plans within a nationally representative sample.

Although variability was found across written asthma action plans, and improvements in readability, suitability, and content are needed, there were also many common elements that would support a move to a single universal standard action plan. (Read the full article)

Most observational studies from Western populations suggest that blood pressure is positively associated with low birth weight and faster infant growth; however, it is unclear whether these associations are biologically based or contextually specific.

In a developed non-Western setting with relatively little socioeconomic patterning of size or growth, birth weight and infant growth had relatively limited impacts on early adolescent blood pressure, which was more strongly related to recent growth and current size. (Read the full article)

Gaining intravenous access in children can be difficult. Recently, several near-infrared devices have been introduced attempting to support intravenous cannulation by visualizing veins underneath skin. Only one of those devices has been evaluated systemically thus far and results are inconclusive.

Although it was possible to visualize veins with near-infrared in most patients, the VascuLuminator did not improve the success of cannulation. An explanation is that the main problem is probably not localization of the vein but insertion of the cannula. (Read the full article)

Although previous studies indicate that perinatal factors are associated with altered neurodevelopment, data on the association between ischemic-hypoxic conditions and attention-deficit/hyperactivity disorder in children are sparse.

This study demonstrates that preeclampsia, birth asphyxia, and respiratory distress syndrome are independently associated with increased risk of attention-deficit/hyperactivity disorder in a large population-based study. (Read the full article)

Cerebral edema (CE) occurs frequently during treatment of diabetic ketoacidosis (DKA) in children. Severe, life-threatening CE occurs rarely, but subclinical CE is common. Whether the rate of infusion of intravenous fluids influences the occurrence or severity of CE is unknown.

This study demonstrates that the rate of fluid infusion in children with DKA does not substantially affect MRI measures of CE. Studies assessing measures other than edema formation are necessary to determine whether fluid infusion rates influence DKA-related brain injury. (Read the full article)

Maternal obesity is an increasingly important public health concern and may adversely affect central nervous system development in offspring. However, few studies have explored the relationship between maternal prepregnancy BMI and neurodevelopmental outcomes in children, with conflicting results.

Using data from a large and contemporary UK birth cohort, we found that maternal prepregnancy BMI is negatively associated with children’s cognitive performance. The relationship appears to become stronger as children get older, although the overall effect size is modest. (Read the full article)

There is widespread belief that many hospital readmissions in adults are avoidable by improvements in care and discharge planning processes, resulting in significant cost savings; however, current studies have not examined the preventability of such readmissions in children’s hospitals.

The overall rate of pediatric 15-day readmissions considered to be preventable was low, less than 2% of total hospital admissions. Pediatric readmissions are unlikely to serve as a highly productive focus for cost savings or quality measurement. (Read the full article)

Although a number of cross-sectional studies have documented associations between teen dating violence victimization and adverse health outcomes, including sexual risk behaviors, suicidality, substance use, and depression, longitudinal work examining the relationship between victimization and outcomes is limited.

This study is the first to demonstrate the longitudinal associations between teen dating violence victimization and multiple young adult health outcomes in a nationally representative sample. Findings emphasize the need for screening and intervention for both male and female victims. (Read the full article)

Low birth weight (LBW) infants (<2500 g) are at risk for cognitive and behavioral problems later in life. During infancy, they are also at risk for iron deficiency, which has been associated with impaired neurodevelopment in other high-risk groups.

Iron supplementation during the first 6 months of life to LBW infants reduces the risk of behavioral problems at 3.5 years. Mild iron deficiency in infancy may be an important, preventable contributor to behavioral problems in children born with LBW. (Read the full article)

The medical home likely plays a positive role in outpatient health outcomes. Asthma is a common and frequent reason for pediatric hospitalization. It is unknown whether having a quality medical home can prevent readmission in children hospitalized for asthma exacerbations.

Poor access to a medical home was associated with increased readmission for asthma, whereas other measured aspects of medical home were not. Children with private insurance and good access to care had the lowest rates of readmission within a year. (Read the full article)

Children with congenital heart disease (CHD) are at increased risk for poor growth. Several factors may play a role in poor growth, including feeding difficulties, increased caloric requirements, and the effects of cardiac lesions on growth regulation.

In children with CHD, impaired growth as measured by weight, length, and head circumference occurs simultaneously rather than sequentially, supporting the theory that altered growth regulation likely plays an important role in the poor growth of children with CHD. (Read the full article)

Sugar-sweetened beverage (SSB) consumption is associated with childhood obesity risk. Because dietary salt intake is a determinant of fluid consumption in adults, a high-salt diet may predict greater consumption of SSBs and therefore increase obesity risk.

In Australian children, the amount of salt consumed was positively associated with fluid consumption, and predicted the amount of SSB consumed. In addition, SSB consumption was associated with obesity risk, indicating a potential link between salt intake and childhood obesity. (Read the full article)

Outcomes analyses after trauma reveal long-term disability but are limited to specific injuries, older data, or all ages combined. There are no contemporary assessments of physical disability among children after inpatient rehabilitation for a wide range of traumatic injuries.

This is the first contemporary study to describe the physical disability of a large pediatric cohort after inpatient rehabilitation for various injuries. After a mean 21-day inpatient rehabilitation stay, significant reductions in functional disability were achieved across injury mechanisms. (Read the full article)

There is evidence that Kingella kingae, the major bacterial cause of osteoarticular infection in children <4 years of age, first colonizes the oropharynx before penetrating the bloodstream and invading distant organs. Diagnosis remains challenging because clinical findings at admission may be normal.

Our study demonstrated for the first time that a simple technique of detecting of K kingae DNA in the oropharynx can provide strong evidence that this microorganism is responsible for the OAI, or even stronger evidence that it is not. (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)

Socioeconomic status (SES) is inversely related to mortality and health in children; the higher an individual’s SES, the less likely illness and death. It is unknown whether the association of SES and pediatric mortality exists in the inpatient setting.

Within children’s hospitals, in-hospital mortality is inversely associated with SES, but is lower than expected for even the lowest SES quartile. The association between SES and mortality varies by clinical service line. (Read the full article)

Although survival of children born with Down syndrome has improved, unexplained racial and ethnic disparities in survival persist in the United States.

This study used population-based data from 10 birth defects monitoring programs in the United States to examine survival trends among children born with Down syndrome and to evaluate the changing influence of survival predictors over the life course. (Read the full article)

The eating of non–nutrient dense snack foods is considered a major factor contributing to childhood obesity. Parents are often ineffective at encouraging healthier snacking habits.

Children consumed fewer calories when snacking on nutrient-rich cheese and vegetables compared with when they were served potato chips. (Read the full article)

When research involving children is determined to present greater than minimal risk but no potential for direct benefit, permission is required from both parents, unless one is not reasonably available. These requirements are variably understood and applied, and guidance is lacking.

In a study on newborn screening, a sizeable percentage of fathers were not reasonably available, reflecting complexities of parental status and family relations. Guidelines developed in this project may provide tools for researchers and institutions to apply in other contexts. (Read the full article)

Infants and toddlers with deformational plagiocephaly (DP) score lower on developmental measures than children without DP and lower than expected relative to test norms.

This study is the first to examine developmental outcomes in preschool-aged children with DP relative to demographically similar children without DP using a standardized, clinician administered assessment. (Read the full article)

Studies have linked bullying with BMI, with overweight and obese youth vulnerable to bullying and its negative psychological and health consequences. However, there has been little comprehensive assessment of weight-based victimization, especially in weight loss treatment–seeking samples of youth.

WBV is prevalent in treatment-seeking youth, who report victimization from peers (92%), friends (70%), parents (37%), and teachers (27%). Providers should discuss WBV in their assessment and treatment of pediatric patients who are overweight or obese. (Read the full article)

Part C early intervention serves ~2.8% of US children who are younger than 3 years old; however, there is evidence that substantial numbers of infants and toddlers with developmental delays receive no early intervention services.

Broad eligibility criteria can classify children who have no delays or minimal delays as candidates for Part C services. Despite this, no jurisdiction provides Part C services to all children who have substantial delays. (Read the full article)

Adequate vitamin D is essential for skeletal health in developing children. Although excess body weight is associated with risk of vitamin D deficiency, the national prevalence of vitamin D deficiency in overweight and obese children is unknown.

Vitamin D deficiency is highly prevalent in overweight and obese children, and severely obese and minority children are disproportionately affected. There are many modifiable factors associated with vitamin D deficiency in overweight and obese children. (Read the full article)
