Background: This study examined changes in multiple physical activity domains during the transition out of high school and psychosocial and environmental determinants of these changes. Methods: A 1-year prospective study was designed. The baseline sample was composed of 244 last-year high school students (58.6% female) from Valencia, Spain. Follow-up rate was 46%. Physical activity and potential determinants were measured by the Global Physical Activity Questionnaire and other evaluated scales in 2 waves. Results: Total physical activity and active commuting (AC) decreased, respectively, by 21% and 36%, only in males. At time 1, access to car/motorbike (inverse), planning/psychosocial barriers (inverse), street connectivity (positive) and parental education (inverse) were significantly associated with AC (P <.05). Prospectively, the increase in distance to school/workplace was associated with AC decrease among males (P <.001). In both genders, there was a decrease in leisure-time physical activity (LTPA; 35% in males, 43% in females). At time 1, self-efficacy and social support were positive correlates of LTPA (P <.05). Social support decreases were associated with reductions in LTPA for males (P <.05). Conclusions: Several psychosocial and environmental correlates of physical activity change were identified, and these are promising targets for interventions.
