Physical activity during the transition from adolescence to adulthood

J Phys Act Health. 2007 Apr;4(2):125-37. doi: 10.1123/jpah.4.2.125.


Background: 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.

Methods: 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.

Results: 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.

Conclusions: 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.
