BACKGROUND: Social relationships are among the strongest predictors of health. The extent to which one is embedded in social networks, also referred to as social integration, has been associated with physical activity in short-term longitudinal and cross-sectional studies. How changes in social integration impact physical activity over longer periods of time is not well understood. METHODS: Longitudinal data from 5 waves of the Americans' Changing Lives study were used (wave 1: n = 3617; wave 5: n = 1427)...

BACKGROUND: Extensive research demonstrates the benefits of fitness on children's health and academic performance. Although decreases in health-related fitness may increase school absenteeism, multiple years of prospective, child-level data are needed to examine whether fitness changes predict subsequent chronic absenteeism status. METHODS: Six cohorts of New York City public school students were followed from grades 5-8 (2006/2007-2012/2013; N = 349,381). A longitudinal 3-level logistic generalized linear mixed model with random intercepts was used to test the association of individual children's changes in fitness and 1-year lagged chronic absenteeism...
