【 摘 要 】

INTRODUCTION:Leisure-Time Physical Activity (LTPA) is a health behavior that is consideredrelatively stable over the course of life; this life-long habit seems to beshaped during youth and early adulthood. LTPA is one of the few healthy behaviorsmore prevalent among men than among women.
METHODS:Data from 3,199 participants of the Pro-Saude Study were analyzed- a cohort of employees of a university in Rio de Janeiro, collected with aself-reported multidimensional questionnaire. The association between LTPA inearly adulthood and later was investigated using multinomial logistic regression,with estimated odds ratios (OR), considering three outcome categories: inactive,insufficiently active, and active. Past LTPA was grouped into three categories:never/rarely (reference category), sometimes and frequently/always. Estimateswere adjusted for: age; participants' schooling, their father's and mother'sschooling, and color/race.
RESULTS:Analysis shows men who engaged in LTPA sometimes and almost always/alwaysin early adulthood had an OR= 1.42 (95% CI: 0.70-2.89) and OR=3.33 (95% CI: 1.82-6.10), respectively, of being physically active in lateradulthood than those who did not engage in LTPA. Among women, the correspondingodds ratios were lower: OR = 1.19 (95% CI: 0.79-1.79) and OR =1.42 (95% CI:1.00-2.04).
CONCLUSION:LTPA during early adulthood is associated with physical activitylater in adulthood, and this association is stronger in men than in women. Publicpolicies that encourage LTPA among youth, with specific efforts directed atwomen, could increase the proportion of physically active adults.
