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)

The prevalence of asthma and associated urgent medical visits vary dramatically across neighborhoods in New York City. Some, but not all, children with asthma wheeze when they exercise.

Exercise-induced wheeze was more common for asthmatic children living in neighborhoods with higher versus lower asthma prevalence. Because exercise-induced symptoms indicate a propensity for rapid-onset symptoms, this increased prevalence may contribute to the observed increase in urgent medical visits. (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)

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)

Because pediatric appendicitis is challenging to diagnose, computed tomography (CT) is used frequently. Childhood radiation exposure is associated with increased risk of cancer. Ultrasound avoids radiation exposure but is less sensitive for appendicitis than CT.

Controlling for referral bias, evaluation at a community compared with a children’s hospital is associated with higher CT and lower ultrasound use before appendectomy. CT and ultrasound accuracy for appendicitis in children varies with hospital type. (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)

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)

Children with sickle cell anemia are at risk of central nervous system damage, including stroke. Even children without evidence of abnormality on neuroimaging are at risk of significant declines in neurocognitive function, starting at early ages.

This study adds the observation that poorer neurocognitive and behavioral function is associated with older age in infants and toddlers with sickle cell anemia, much earlier than previously expected. (Read the full article)

Previous studies suggest that hospitals under the greatest financial strain may be more prone to adverse events because they have limited resources to invest in quality and safety.

The patient population served, rather than hospital category, best predicts measured quality, underscoring the need for robust risk adjustment when incentivizing quality or comparing hospitals. Thus, problems of quality may not be systemic across hospital categories. (Read the full article)

A reduced nephron number is associated with glomerular hyperfiltration, resulting in renal injury such as hypertension, proteinuria, and chronic kidney disease. Patients with a solitary functioning kidney have an increased risk of dialysis in early adulthood.

This study demonstrates that a subset of children with a solitary functioning kidney progress toward renal injury during childhood. Risk factors for renal injury are ipsilateral anomalies of the kidney and urinary tract and small renal length. (Read the full article)

Effective interventions are still elusive for the large numbers of children affected by overweight/obesity. The value of targeting physical activity (PA) remains unclear because its predictive relationship with improved BMI is still surprisingly poorly quantified.

In overweight and mildly obese children presenting to primary care, 3-year changes in PA (especially the moderate-vigorous component) predicted BMI outcomes. However, the effect was small, possibly explaining the disappointing BMI outcomes of brief primary care interventions targeting PA. (Read the full article)

Presleep activities (eg, television watching) have been implicated in the declining sleep duration of young people. However, previous research reported on selected presleep activities, raising the possibility that important activities in this period are not accounted for.

This is the first study in youth to construct the presleep period by using a use-of-time approach. Twin trajectories of higher screen time and lower nonscreen sedentary time/self-care were evident in late sleepers, with the opposite pattern occurring in early sleepers. (Read the full article)

Heuristics are decision-making aids or shortcuts that ease the task of making a wide variety of decisions in diverse contexts. Little is known about the heuristics that parents of children with serious illness use when confronting difficult decisions.

Parents of children with life-threatening illnesses use several different types of heuristics, explicitly, in making sense of complex situations, making decisions, and communicating these decisions to others. Better understanding of these heuristics may improve communication and decision support. (Read the full article)

Previous evaluations of local reactions after the fifth diphtheria-tetanus-acellular pertussis (DTaP) vaccine in children 4 to 6 years of age have revealed that vaccination in the thigh is associated with a lower risk of local reactions compared with vaccination in the arm.

Among children 12 to 35 months of age, injection of DTaP vaccine in the thigh is associated with a lower risk of local reactions compared with vaccination in the arm. (Read the full article)

Survival estimates for preterm infants are vital for counseling parents, informing care, and planning services. Widely use estimates of in-unit survival derived from a large UK population for infants born at <33 weeks’ gestational age have been available since 1999.

These survival charts have been updated and will be of use to clinicians, parents, and managers. An alternative method for graphical representation of survival probabilities is offered: contour survival plots. (Read the full article)

Routine screening of potentially abused children with hepatic transaminases has been recommended, using a threshold of 80 IU/L to determine the need for further testing, but practice is variable, and this threshold has not been validated.

This study identified abdominal injury in a significant fraction of potentially abused children with transaminases >80 IU/L. (Read the full article)

Birth asphyxia, or failure to initiate or sustain spontaneous breathing at birth, contributes to ~27% to 30% of neonatal deaths in resource-limited countries, including Tanzania. Without change, these countries will fail to meet Millennium Development Goal 4 targets by 2015.

The Helping Babies Breathe program was implemented in 8 hospitals in Tanzania in 2009. It has been associated with a sustained 47% reduction in early neonatal mortality within 24 hours and a 24% reduction in fresh stillbirths after 2 years. (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)

Care coordination has been proposed as a key mechanism for increasing quality and reducing costs of care. Little is known about the degree to which disparities exist in care coordination or whether having high-quality primary care attenuates disparities.

A considerable proportion of parents reported unmet care coordination needs for their children, especially parents of children with special health care needs. Black and Latino children also may have more unmet needs because they received family-centered care less often. (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)

Quality urban playgrounds that are accessible and safe support physical activity and decrease injury rates. Little is known about the quality and accessibility of playgrounds in Chicago public parks.

Most playgrounds in Chicago are in fair condition, yet access to quality playgrounds varies by neighborhood. Public/private collaboration can lead to improved playgrounds, and failing playgrounds can be improved with modest investment. (Read the full article)

A number of studies have shown that home-visiting interventions can improve outcomes for children being raised in families that face multiple adversities. It is less clear how well these benefits are sustained over long periods.

The current study shows that the Early Start program of home visitation has benefits in terms of reducing child abuse, increasing parental competence, and improving childhood behavioral adjustment for up to 9 years, suggesting long-term benefits of home visitation. (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)

Prevalence of hypertension in children increased significantly over the past few decades, tracks into adulthood, and is a major risk factor for cardiovascular disease. However, current prevalence estimates in children have largely been based on studies conducted in school environments.

The current study reports the prevalence of childhood hypertension in community pediatric practice, which provides a typical pediatric examination environment, unlike blood pressure measured in school. The results show a significantly lower prevalence than what has previously been reported. (Read the full article)

Amblyopia affects 2% to 4% of the US population and is preventable In January 2011, the US Preventive Services Task Force concluded there is insufficient evidence to support vision screening in children younger than age 3 years.

Results of the Iowa photoscreening program in 210 695 children older than 11 years suggest photoscreening reliably detects amblyogenic risk factors in children 1 to 3 years of age, and we recommend photoscreening children starting at 1 year of age. (Read the full article)

Among youth with asthma, tobacco smoke exposure causes increased asthma morbidity. Little is known about changes over time in tobacco smoke exposure among youth with asthma in a national sample.

Our analysis reveals a decrease in environmental tobacco smoke exposure among children and adolescents with current asthma in the United States from 1988–1994 to 2005–2010, but a majority of youth with asthma remain exposed to environmental tobacco smoke. (Read the full article)

Follow-up skeletal surveys are conducted commonly in children with suspected physical abuse, despite limited evidence. Different guidelines recommend follow-up skeletal surveys in children with abnormal initial skeletal surveys or in cases with high risk.

Across several centers, follow-up skeletal surveys revealed new information in >20% of cases and frequently affected the perceived likelihood of abuse, even in cases where the initial level of concern for abuse was moderate. (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)

The rise in type 2 diabetes in youth is a major public health concern thought to be partially due to decreasing activity levels and increasing obesity. The role of sedentary time as a possible contributor also needs to be examined.

Measured objectively, obese youth, with or without type 2 diabetes, spend little time in moderate to vigorous physical activity. Those with type 2 diabetes, however, were significantly more sedentary than their obese counterparts, identifying an important area for future intervention efforts. (Read the full article)

Health care transition services assist youth with special health care needs (YSHCN) in transitioning to adult care without gaps in services or health insurance coverage. Less than half of YSHCN receive anticipatory assistance in this transition; receipt of these services for youth with autism spectrum disorder is unknown.

Youth with autism spectrum disorder receive transition services half as often as youth with special health care needs. Quality of health care is associated with increased receipt of health care transition services. Presence of comorbid conditions decreased receipt of transition services. (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)

Bisphenol A (BPA) is an environmental endocrine disruptor that can leach from polycarbonate plastics and epoxy resins, leading to widespread exposure. Fetal and early postnatal periods are particularly vulnerable to exposure to BPA.

This study identified medical devices as a potential source of exposure to BPA among premature infants in the NICU, even when efforts to reduce polycarbonate plastics were taken. (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)

The presence of elevated cardiometabolic risk factors, such as obesity, high glucose or lipid levels, and smoking, in adolescents has been shown to be associated with earlier onset of chronic conditions, such as diabetes and heart disease.

Obesity, smoking, and elevated glucose increases the risk of dying before the age of 55 years. This is the first study to focus on risk factors and mortality among adolescents and young adults in a nationally representative US sample. (Read the full article)

Isolated case reports of abnormal voice after extremely preterm birth are well described; however, there are no systematic studies of long-term voice outcomes in children born preterm.

Significant voice abnormalities were found in more than half of tested children born before 25 weeks’ gestation. Multivariable analyses showed that the number of intubations, not the duration of intubation, and female gender were strongly associated with this adverse outcome. (Read the full article)

Children with Lyme and septic arthritis of the knee may present similarly, although septic arthritis requires prompt treatment initiation to avoid joint destruction. Clinicians must make initial management decisions without Lyme serology and bacterial culture results.

Our clinical prediction rule accurately identified patients at low risk for septic arthritis in a Lyme disease–endemic area. In the appropriate clinical context, low-risk patients may be spared invasive testing such as diagnostic arthrocentesis. (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)

Failure to thrive (FTT) is a common and vexing pediatric problem. Evaluation has historically involved large batteries of tests, multiple consultations, radiologic studies, and prolonged hospital admissions, resulting in significant costs and inconsistent results.

Scheduled failure to thrive (FTT) admissions on weekends result in increased lengths of stay and health care costs compared with weekday admissions of similar levels of complexity. Reduction in planned weekend admissions for FTT could significantly reduce health care costs. (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)

Pediatric training programs use simulation for procedural skills training. Research demonstrates student satisfaction with simulation training, improved confidence, and improved skills when retested on a simulator. Few studies, however, have investigated the clinical impact of simulation education.

This is the first multicenter, randomized trial to evaluate the impact of simulation-based mastery learning on clinical procedural performance in pediatrics. A single simulation-based training session was not sufficient to improve interns’ clinical procedural performance. (Read the full article)

Reductions in infant mortality in the 20th century have not continued. Racial and socioeconomic inequalities in both infant mortality and sudden infant death syndrome (SIDS) persist. Rates of infant mortality in English-speaking countries are higher than the Organisation for Economic Co-operation and Development average.

At least 16.4% of SIDS and 3.4% of infant deaths not classified as SIDS are attributable to maternal alcohol use. Maternal alcohol-use disorder increases the risk of infant mortality through direct effects on the fetus and indirectly through environmental risk factors. (Read the full article)

Skin and soft tissue infections (SSTIs) are a common pediatric condition often requiring inpatient management. Several studies describe recent increases in hospitalizations due to SSTIs.

In addition to rising hospitalizations, analysis of pediatric SSTI resource utilization trends revealed a twofold increase in incisions and drainages over a 13-year period. A growing number of incisions and drainages were performed in younger children. (Read the full article)

In Mexico, substantial declines in childhood diarrhea deaths have been documented since the introduction of the rotavirus vaccine in 2007. However, there is concern of lower vaccine effectiveness in less developed regions of Mexico with higher diarrhea-related mortality.

We documented significant and comparable declines across all 3 regions of Mexico with different levels of development, indicating equitable vaccine distribution to children with varying risk of mortality and reaffirming the beneficial effects of rotavirus vaccination against fatal diarrheal disease.
