New research examines association between gun access and adolescent health

A new study found that personal gun access is associated with depression, suicidal ideation, and perceiving school as unsafe. In contrast, attending a school with common gun access is linked to lower odds of perceiving school as unsafe. The findings suggest complex associations between gun access and adolescent health.

Early lipids boost brain growth for vulnerable micro-preemies

Research at Children's National Hospital found that early lipid intake significantly increases global brain volume and boosts regional brain activity in micro-preemies. This is particularly important for preterm infants who are vulnerable to growth failure and neurocognitive impairment after birth.

Nationwide study suggests obesity as an independent risk factor for anxiety and depression in young people

A nationwide study published at the European Congress on Obesity found that children and adolescents with obesity are more likely to develop anxiety or depression compared to their peers. The study, which analyzed over 12,000 Swedish children, revealed a clear increased risk of anxiety and depressive disorders in those with obesity.

New study aims to understand opioid fill patterns in children

A new study examining opioid fill patterns among Medicaid-enrolled children in the US revealed that prescriptions for these age groups were relatively rare, with an adjusted rate of 0.8% by 2016. The study also found that opioids were most frequently prescribed in combination with other pain relievers.

In HIE, lower heart rate variability signals stressed newborns

Research at Children's National Hospital found that infants with hypoxic-ischemic encephalopathy (HIE) exhibit lower heart rate variability, a marker of autonomic nervous system stress. This study suggests heart rate variability as a valuable physiological biomarker for detecting brain injury in babies with HIE.

HPV vaccine coverage is far behind other infant vaccines in many US states

A new study reveals that HPV vaccine coverage is far behind other infant vaccines, with only 13 and three US states reaching above 60% coverage by 2016. The study tracked over 7.5 million children from 2003 to 2016 and found increased uptake among girls and boys, but still fell short of the Healthy People 2020 goal of 80%.
