A systematic review and meta-analysis of studies involving more than 230,000 adolescents found that greater social jet lag was associated with higher anxiety levels. The findings identified a consistent but small association and did not establish causality.

Genetic analyses of nearly 80,000 infants identified variants associated with toddler activity levels and other early behavioral traits. Several of these genetic signals overlapped with those previously linked to ADHD and autism, although the findings do not establish causality.

Sleep midpoint variability, duration variability, and social jetlag were each associated with lower receptive vocabulary and visuospatial memory scores in 379 preschool-age children, with executive attention unaffected by any sleep regularity measure.

Among 206,464 mother-child pairs, children of mothers with stably optimal glycemic management after a GDM diagnosis had obesity risk at age 10 nearly identical to children unexposed to GDM. Children of mothers with suboptimal trajectories had a 62% higher risk.

In a small neuroimaging substudy of children exposed to prenatal stress during Superstorm Sandy, stronger early adaptive skills were associated with limbic activation patterns resembling unexposed peers.
