The present study aimed at assessing the association between leisure-time physical activity at 15 and 19 years of age, and adult leisure-time physical activity at 23 years of age. In 1982, all 5914 hospital births occurring in Pelotas, whose family lived in the urban area, were identified and these subjects have been followed. In 1997 (15 years) and 2001 (19 years) a sample of the cohort was traced, whereas in 2004-5 we attempted to follow all cohort members. Physical activity was measured at all these visits. Among 1076 individuals evaluated in 1997, 928 subjects provided data on leisure-time physical activity in 2001 and 2004-5. At the mean age of 23 years, 37.3% of the individuals were considered as physically active at leisure-time (reported at least 150 minutes per week of physical activity). Even after controlling for confounding by demographic and socioeconomic factors, the prevalence ratio to be active at 23 years was 4.49 (CI95%: 1.79, 11.21) and 2.49 (CI95%: 1.41, 4.40) among men and women, respectively, who were considered as active at 15 and 19 years in comparison to those who were not active at both visits. Active adolescents are more likely to be active in early adulthood.
