Associations Between Cumulative Risk, Childhood Sleep Duration, And Body Mass Index Across Childhood, Tiffany Phu, Jenalee R. Doom

Psychology: Faculty Scholarship

Background: Although associations between cumulative risk, sleep, and overweight/obesity have been demonstrated, few studies have examined relationships between these constructs longitudinally across childhood. This study investigated how cumulative risk and sleep duration are related to current and later child overweight/obesity in families across the United States sampled for high sociodemographic risk.

Methods: We conducted secondary analyses on 3690 families with recorded child height and weight within the Fragile Families and Child Well-Being Study. A cumulative risk composite (using nine variables indicating household/ environmental, family, and sociodemographic risk) was calculated for each participant from ages 3-9 years. Path analyses …

Infant Motor Development Predicts The Dynamics Of Movement During Sleep, Aaron Demasi, Melissa N. Horger, Anat Scher, Sarah E. Berger

Publications and Research

The characteristics of infant sleep change over the first year. Generally, infants wake and move less at night as they grow older. However, acquisition of new motor skills leads to temporary increases in night waking and movement at night. Indeed, sleep-dependent movement at night is important for sensorimotor development. Nevertheless, little is known about how movement during sleep changes as infants accrue locomotor experience. The current study investigated whether infant sleep and movement during sleep were predicted by infants' walking experience. Seventy-eight infants wore an actigraph to measure physical activity during sleep. Parents reported when their infants first walked across …
