In a cross-sectional study, Fakhouri et alArticle found that fewer than 4 in 10 elementary school–aged US children met physical activity and screen-time recommendations.
Maguire et alArticle found that the most important determinants of 25-hydroxyvitamin D levels in early childhood were current vitamin D supplementation and daily cow's milk intake.
In a retrospective cohort study of 320 children with caregiver-reported intimate partner violence (IPV), Campbell et alArticle found that resolution of IPV after an investigation for suspected child maltreatment was associated with sustained reductions in clinically significant child behavior problems.
Sun et alArticle investigated potential reasons contributing to the failure of pediatric trials of drugs for the abortive treatment of migraine submitted to the US Food and Drug Administration. High placebo response rates were consistent across all trials and may represent the principal challenge.
El-Chammas et alArticle found that placebo was effective in reducing headaches in children and adolescents. Topiramate and trazodone had limited evidence supporting efficacy for episodic migraines; other commonly used drugs had no evidence supporting their use in children and adolescents.
Zemek et alArticle reviewed the literature to identify prognosticators of persistent concussion symptoms (PCS) following pediatric concussion. They found that minimal, and at times contradictory, evidence exists to associate clinically available factors with development of PCS in children.
Chiolero et alArticle appraised recommendations for the screening for elevated blood pressure (BP) in children and adolescents. It remains undetermined whether the benefits of universal BP screening in children outweigh the harm. At the population level, efforts should focus on the primary prevention of elevated BP and other risk factors.
Glanz et alArticle evaluated the trends in undervaccination in a population of 323 247 children aged 2 to 24 months and compared health care use rates between the undervaccinated and age-appropriately vaccinated children. Undervaccination appeared to have increased over time.
Getahun et alArticle examined trends in attention-deficit/hyperactivity disorder (ADHD) by race/ethnicity, age, sex, and median household income. The incidence of ADHD diagnoses increased by 24% over the last decade, and increased for whites, blacks, and Hispanics.
In a cross-sectional study, Boyer et alArticle found evidence that the use of female friendship networks is a feasible and acceptable means to engage at-risk African American and Hispanic/Latina young women in HIV screening.
