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)

Children with medical complexity are high users of acute health care, but little is known about their service use across the continuum of care services and in the context of overall health care expenditures.

Although accounting for <1% of the child population, children with medical complexity use almost one-third of all pediatric health care expenditures and make multiple transitions across providers and health care settings. (Read the full article)

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)

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)

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)

Lifestyle and vulnerability associated with food allergy might predispose affected children to being bullied. Our previous parent survey identified high rates of bullying in this population, but child reports and emotional impact were not assessed.

Bullying was common, often involving threats with food. Bullied food-allergic children, compared with nonbullied, report higher anxiety and lower quality of life. Parental awareness of bullying (~50% of cases) was associated with better social and emotional functioning in the child. (Read the full article)

Children born at very low birth weights have significant catch-up weight gain but differences in height remain. Their BMI, however, tends not to be higher than expected. Data are lacking regarding representative cohorts, defined by gestation and compared with contemporaneous controls.

In a geographic cohort of extremely preterm participants followed until age 18, compared with term controls, weight differences diminish over time, and height differences persist. BMI at age 18 is similar. Height at age 2 is a better predictor of final height than midparental height. (Read the full article)

Complementary and alternative medicine (CAM) use is common among children, especially those with chronic, recurrent, or incurable conditions. Concurrent use of CAM with conventional medications is of concern and needs to be assessed, especially in vulnerable patient populations.

CAM use is high among pediatric cardiology, gastroenterology, neurology, oncology, and respiratory patients, most of whom use CAM concurrently with conventional care. This study provides additional evidence to suggest the use of CAM be included in routine patient history taking. (Read the full article)

Few reports have explored the measurement validity of the relative value unit (RVU) system, particularly in pediatrics. The RVU system, although broadly applied in health care settings, was developed for the adult population and thus may possess unique inadequacies in pediatrics.

We found deficiencies in the ability of the RVU system to capture features of case mix complexity and differences related to age. Additional investigation may be warranted to determine the validity of RVU as a measurement tool in pediatrics. (Read the full article)

Bilateral acute otitis media (AOM) is considered more severe than unilateral AOM, and several guidelines recommend more active management of bilateral AOM. However, severity of symptoms and otoscopic signs of bilateral and unilateral AOM have previously not been comprehensively studied.

Bilateral AOM seems to be clinically only a slightly more severe illness than unilateral AOM. When assessing AOM severity, bilaterality should not be used as a determining criterion; instead, the child’s symptoms together with otoscopic signs should also be acknowledged. (Read the full article)

Research indicates that adolescents who perceive their school to have a positive socioeducational environment are at reduced risk of developing depressive symptoms. However, there is limited evidence that school environments can influence adolescent emotional health independently from individual perceptions.

This multilevel longitudinal study shows that better school socioeducational environments, as assessed at the school level, reduce the prospective risk of depressive symptoms in adolescents. This association is shown to be independent from confounders and stronger in girls than boys. (Read the full article)

Preterm born children have cognitive problems that include deficits in working memory. Computer-based working memory training has been reported to improve cognitive function in children.

A computer-based working memory training program designed for preschoolers seems effective in very low birth weight children, not only on working memory tasks, but also by having a generalizing effect regarding memory and learning. (Read the full article)

Most studies focus on health of foster children or local samples of young children. One previous study examined a national cohort longitudinally but did not address the full age group or range of conditions at the time of initial investigation.

Using 2 approaches to assess children (aged 0–17.5 years) who have chronic health conditions, we found that regardless of placement, investigated children had much higher rates of these conditions than the general population at the time of initial assessment. (Read the full article)

Rapid initiation of effective chest compressions (CCs) for patients in cardiac arrest improves outcomes, yet even trained rescuers fail to provide consistently effective CCs. Pediatric data on CC quality and objective measures of CC work are limited.

CC quality deteriorates similarly in pediatric and adult models, and overall work done to compress the pediatric chest is similar to that in adults. Power output during CC performance is analogous to that generated during intense exercise such as running. (Read the full article)

UV radiation exposure in tanning beds is associated with an increased risk of skin cancer. Because of the rising rate of melanoma, the World Health Organization recommends that persons <18 years of age not use tanning devices.

Despite scientific evidence to the contrary, tanning facilities in Missouri, a state without indoor-tanning regulations, often misinformed consumers regarding the risk of skin cancer and would allow children as young as 10 years old to use tanning devices. (Read the full article)

Of more than 2 million children infected with HIV, almost 90% live in resource-limited settings where pediatric HIV care is often suboptimal. Implementing electronic health records with computerized decision support offers a potential tool for improving care.

This randomized, controlled trial demonstrates that computer-generated clinical reminders can significantly improve clinician compliance with HIV care guidelines for children in a resource-limited setting. This intervention is scalable as developing countries implement electronic health record systems. (Read the full article)

The Supplemental Nutrition Assistance Program (SNAP) is the largest federal nutrition assistance program. Studies among adults suggest that SNAP participation may be associated with suboptimal diets. Few studies have extensively examined these associations among children.

SNAP participation was not associated with childhood obesity. SNAP children consumed diets poorer in some aspects than nonparticipants, but intake of some micronutrients was higher. The diets of both groups of low-income children were far from meeting dietary guidelines. (Read the full article)

Expectations are high that electronic health record–based clinical decision support and performance feedback will improve adherence to guidelines by delivering relevant and actionable information to clinicians. Few studies have evaluated these assertions or examined the combined effects of decision support and feedback.

Clinical decision support customized to a patient’s history and presentation and performance feedback are both effective for improving adherence to guidelines for otitis media. However, the combination of the 2 interventions is no better than either delivered alone. (Read the full article)

Although a growing body of literature suggests links between parental incarceration and negative child outcomes, research that uses representative US samples and focuses on health outcomes is limited.

Using a nationally representative US sample, we examined the association between parental incarceration and young adult mental and physical health outcomes. Results suggest childhood exposure to parental incarceration is associated with increased risk of long-term health problems. (Read the full article)

Previous studies have suggested that health care providers, family members, friends, and others play a role in shaping parents’ vaccination decisions. Other research has suggested that the media can influence whether parents decide to vaccinate their children.

Through the application of social network analysis, this study formally examines and quantifies how parents are influenced by the people and sources around them. Its findings suggest that social networks are important, particularly for parents who do not completely vaccinate. (Read the full article)

At least half of the achievement gap for low-income, minority children is present at kindergarten entry; however, there are no population-level early childhood interventions that effectively engage and support families and teachers to ameliorate the impact of adversity on achievement.

This study evaluated ParentCorps, a family-centered, school-based intervention to promote self-regulation and learning for all children entering school in disadvantaged, urban neighborhoods. ParentCorps results in higher kindergarten achievement among low-income, minority children. (Read the full article)

Pulse oximetry testing in newborns can detect asymptomatic cases of critical congenital heart defects and has been added to the US Recommended Uniform Screening Panel. However, the impact that earlier diagnosis may have on survival in this population is unclear.

One-year survival for infants with critical congenital heart defects has been improving over time, yet mortality remains high. Survival has been greatest for those diagnosed after 1 day of age and may increase more with screening using pulse oximetry. (Read the full article)

Studies reveal that mothers of infants with colic (defined by Wessel’s criteria of >3 hours per day of distress) are more likely to develop depression. No studies have examined whether the consolability of infant crying predicts maternal depression risk.

Prolonged inconsolable infant crying has a stronger association with maternal depressive symptoms than overall daily duration of fussing and crying, suggesting that a mother’s report of inability to soothe her infant may be a powerful indicator of her depression risk. (Read the full article)

The United States switched from whole-cell to acellular pertussis vaccines during the 1990s. Whether pertussis risk during a California outbreak differed between teenagers who previously received whole-cell or acellular pertussis vaccines early in life has not been reported.

We evaluated pertussis risk in 10 to 17 year olds at Kaiser Permanente Northern California during a recent pertussis outbreak. Those given whole-cell pertussis vaccines in childhood were more protected than those given acellular pertussis vaccines. (Read the full article)

Exemption rates for immunization requirements have until recently been stable in states permitting religious exemptions. States with easy exemption processes have seen higher rates of vaccine-preventable diseases.

In New York, the rate of religious exemptions has increased. Counties with higher rates of exemption have a greater incidence of pertussis. (Read the full article)

Although concussion is increasingly being diagnosed in the pediatric population, little is known about what factors lead to prolonged postconcussive symptoms in children. In particular, the effect of previous history of concussion on recovery from a repeat injury is unclear.

Children with a history of previous concussion, particularly recent or multiple concussions, are at increased risk for prolonged symptoms after concussion. This suggests that repeat concussion, particularly within a vulnerable time window, may lead to longer duration of symptoms. (Read the full article)

Elevated blood pressure (BP) has long-term influence on the atherosclerotic process. The relative predictive ability of the standard BP definition endorsed by the National High Blood Pressure Education Program and the recently proposed 2 simplified definitions has not been studied.

Simplified pediatric BP tables predict risk of high adult arterial stiffness as well as the complex table does. These simple screening tools could be used for identifying pediatric subjects at risk and for intervening to improve adult cardiovascular outcomes. (Read the full article)

Feeding difficulties often emerge during the neonatal period and affect neonatal growth. Growth throughout the first years of life is associated with children’s IQ scores and risk of behavioral problems.

Among infants born full term (≥37 weeks’ gestation) with birth weight ≥2500 g, gain in weight and head circumference during the neonatal period is associated with higher IQ, but not with behavior at 6.5 years of age. (Read the full article)

Young adult smokers frequently encounter the health care system as parents coming in for their child’s medical visit. Child health care clinicians, however, do not typically provide smoking cessation assistance to parents.

This national cluster-randomized trial demonstrates that a tobacco dependence intervention for parents can be effectively implemented in routine pediatric outpatient practice. (Read the full article)

Child maltreatment is a serious and prevalent public health problem in the United States. Responsible for substantial morbidity and mortality, maltreatment affects children's physical and mental health.

Although many health impacts of child maltreatment have been documented, no claims-based study has quantified the impact of maltreatment on health service utilization and costs. This study presents systematic claims-based estimates of maltreatment impacts on utilization and costs for the Medicaid population. (Read the full article)

Functional somatic symptoms (FSS) in children account for 10% to 15% of visits in medical services. Few studies have investigated the full range of pediatric FSS and factors linked to the medical help-seeking for young children with these symptoms.

More parental worries, higher symptom severity and impact, and previous contact to medical services are found among the children with FSS who seek medical consultation. Putative risk mechanisms include the early pattern of health care use and parental worries. (Read the full article)

Studies have highlighted a lack of patient awareness of potential increased cancer risks associated with computed tomography (CT) scans in adult patients and in nonurgent settings. However, little is known about parental awareness of these risks in an emergency setting.

Approximately half of parents were aware of the potential cancer risks from CT scans in an emergency setting. Although risk disclosure moderately reduced willingness to proceed with recommended testing, almost all parents preferred an informed discussion before CT imaging. (Read the full article)

Obstacles to vaccine delivery, including poverty, reduced access to medical care, and incomplete understanding of vaccine safety and importance, result in suboptimal coverage rates in some populations, allowing for disease outbreaks. Multicomponent interventions are successful in increasing immunization coverage rates.

We show that collaboration with local resources, including the county health department and a large community-based organization, effectively increases immunization coverage rates in low-income, resource-poor children. (Read the full article)

Although studies have examined family socioeconomic status as income and educational and employment status, emerging research suggests indicators of material hardship, such as diaper need, are increasingly important to child health. Diaper need has not been examined in the scientific literature.

This study quantifies diaper need, proposes a method to measure diaper need, and explores psychosocial and demographic variables associated with diaper need in a large sample of low-income families. (Read the full article)

Previous research on potential deleterious effects of typically developing children growing up in households with children with disability has produced mixed results. Research methods have been cited as a problem in many studies.

This is the largest known empirical study comparing functional impairment in siblings living with a child with disability and siblings residing with children who are typically developing. This study also follows the trajectory of functional impairment across 2 measurement periods. (Read the full article)

Blood cultures are a common investigation in children admitted to the hospital with skin and soft tissue infections. The yield of blood cultures in this condition is unknown.

Blood cultures are not useful in children admitted to the hospital with uncomplicated skin and soft tissue infections, and they may be associated with increased length of hospital stay. (Read the full article)

Tympanometry provides a measure of middle ear function. There has been no description of the relationship between measurements of middle ear function in the absence of gross anatomic defects and clinical outcome among children with acute nontraumatic coma.

This study reveals an unexpected association between abnormal middle ear function and death in childhood acute coma. These findings call for more investigations on the relationship between middle and inner ear anatomy and function and intracranial dynamics and clinical outcomes. (Read the full article)

Despite the existence of authoritative guidelines to assist primary care physicians in identifying and managing attention-deficit/hyperactivity disorder (ADHD), ample evidence demonstrates that they continue to diagnose and treat this disorder suboptimally.

The introduction of a clinical decision support module resulted in higher quality of care with respect to ADHD diagnosis including a prospect for higher quality of ADHD management in children. (Read the full article)

Pulse oximetry screening at 24 hours of age improves detection of critical congenital heart disease in asymptomatic newborns.

This study describes an initial experience with pulse oximetry screening for critical congenital heart disease and provides a strategy for preparing for state implementation of recent federal newborn screening recommendations. (Read the full article)

Adoptees living in Sweden are at increased risk of suicide attempt compared with nonadopted individuals, although factors mediating this risk are largely unknown. Whether adoption status represents a risk for adoptees living in the United States remains unresolved.

The odds for reported suicide attempt are elevated in US adoptees relative to nonadoptees, the first demonstration of increased risk in US adoptees placed in nonrelative families. This risk is partially mediated by other established risk factors for suicide attempt. (Read the full article)

Previous studies have shown that nonmedical exemptions (NMEs) to immunization cluster geographically and contribute to outbreaks of vaccine-preventable diseases such as pertussis. The 2010 pertussis resurgence in California has been widely attributed to waning immunity from acellular pertussis vaccines.

This study provides evidence of spatial and temporal clustering of NMEs and clustering of pertussis cases and suggests that geographic areas with high NME rates were also associated with high rates of pertussis in California in 2010. (Read the full article)

The 1-dose childhood varicella vaccination program in the United States resulted in dramatic declines in varicella incidence, hospitalizations, and deaths. There is little information on the impact of the 2006 recommendation for 2-dose varicella vaccination of children on varicella epidemiology.

In the first 5 years of the 2-dose varicella vaccination program, declines in varicella incidence were seen in all age groups, including infants who are not eligible for varicella vaccination, providing evidence of the benefit of high population immunity. (Read the full article)

Several studies have been published evaluating the impact of 2011 Accreditation Council for Graduate Medical Education duty hour regulations. Although resident quality of life may be improved, it appears that resident education and patient care may be worse.

This is the first study to evaluate pediatric program director approval of 2011 Accreditation Council for Graduate Medical Education Common Program Requirements and the perceived impact of the regulations on patient care, resident education, and quality of life. (Read the full article)

Use of complementary and alternative medicine (CAM) is increasingly common among American youth; however, information on use of CAM among youth with recurrent headache (HA) is limited.

Youth across a range of chronic conditions experience HA. These youth are more likely to use CAM. Use and expenditures for conventional medical care, and increased difficulties in activity and functioning are greater for youth with HA who use CAM. (Read the full article)

Although providing improved survival for infants with very severe cardiorespiratory problems, the use of neonatal extracorporeal membrane oxygenation has high rates of disability in survivors. Mild hypothermia has been shown to limit brain injury in a range of patient groups, including newborns.

Infants who received extracorporeal membrane oxygenation and mild hypothermia did not show an improved neurodevelopmental outcome, and nonsignificant trends in the data suggested a small adverse effect. Use of hypothermia in other potential patient groups should be thoroughly tested. (Read the full article)

Children with chronic illnesses tend to be sicker during infections than previously healthy children but are triaged in the same way, even though the validity of triage systems has not yet been evaluated in these chronically sick children.

The performance of the Manchester Triage System was lower for children with a chronic illness than for previously healthy children. Children with cardiovascular illnesses, respiratory illnesses, gastrointestinal illnesses, or other congenital or genetic defects were especially at risk of being undertriaged.

Breast milk is protective against many conditions, but its role in allergy has not been established. Infant-feeding recommendations support exclusive breastfeeding for 26 weeks, whereas allergy prevention recommendations advise exclusive breastfeeding for 4 to 6 months with continued breastfeeding thereafter.

Evidence that continued breastfeeding while solids are introduced into the diet and delaying the introduction of solids until at least 17 weeks of age are associated with fewer food allergies. (Read the full article)

Broad-spectrum antibiotics are frequently used to empirically treat children hospitalized with community-acquired pneumonia despite recent national recommendations to use narrow-spectrum antibiotics.

Narrow-spectrum antibiotics are similar to broad-spectrum antibiotics for the treatment of children hospitalized with community-acquired pneumonia in terms of clinical outcomes and resource utilization. This study provides scientific evidence to support national consensus guidelines. (Read the full article)

Payment arrangements that blend global budgets with pay-for-performance are proliferating. However, little is known about how these contracts affect pediatric health care quality and spending for children with and without special health care needs receiving care from large provider organizations.

A prototypical global budget contract significantly improved preventive care quality measures tied to pay-for-performance, especially for children with special health care needs. It did not alter trends for spending or for quality measures that were not tied to pay-for-performance. (Read the full article)
