We examine how age, life course roles, and contextual variables relate to both the composition and the overall level of physical activity in late adolescence and early adulthood.
Data on respondents age 15 to 29 y in the 2003 American Time Use Survey are used to estimate multivariate logistic regressions that assess what factors are associated with meeting the recommended level of physical activity.
The proportion of respondents who do 30 min or more of team sports declines over the 15 to 29 y age range even after controlling for life course and contextual covariates. Parenthood, employment status, and school enrollment have selective effects on the odds of meeting physical activity recommendations.
Given the declines in team sports activities, schools and public health officials should consider the potential benefits of promoting other options such as cardiovascular activities, strength training activities, and/or active transportation.

Complete streets require evaluation to determine if they encourage active transportation.
Data were collected before and after a street intervention provided new light rail, bike lanes, and better sidewalks in Salt Lake City, Utah. Residents living near (<800 m) and far (≥801 to 2000 m) from the street were compared, with sensitivity tests for alternative definitions of near (<600 and <1000 m). Dependent variables were accelerometer/global positioning system (GPS) measures of transit trips, nontransit walking trips, and biking trips that included the complete street corridor.
Active travel trips for Near-Time 2 residents, the group hypothesized to be the most active, were compared with the other 3 groups (Near-Time 1, Far-Time 1, and Far-Time 2), net of control variables. Near-Time 2 residents were more likely to engage in complete street transit walking trips (35%, adjusted) and nontransit walking trips (50%) than the other 3 groups (24% to 25% and 13% to 36%, respectively). Bicycling was less prevalent, with only 1 of 3 contrasts significant (10% of Near-Time 2 residents had complete street bicycle trips compared with 5% of Far-Time 1 residents).
Living near the complete street intervention supported more pedestrian use and possibly bicycling, suggesting complete streets are also public health interventions.
