Physical activity and obesity are known to be associated. We investigated whether a change in leisure time physical activities (LTPA) predicts a subsequent weight change, or vice versa.We used data from a longitudinal study among Danish adults surveyed in 1983-1984, 1987-1988, and 1993-1994. Between two sequential surveys, the change in LTPA was grouped as no change, became less or more active; the change in body weight was defined as no change, lost or gained of more than one body mass index (BMI) unit.Among 2386 adults, change in LTPA was not associated with subsequent weight change. However, a loss in body weight (BMI change < -1 unit) was associated with subsequent either becoming less [OR = 1.49, 95% CI (1.03-2.15)] or borderline more active [OR = 1.37, 95% CI (0.99-1.90)]. Subgroup analyses showed particularity among females that a loss in body weight was associated with subsequent becoming more active [OR = 1.83, 95% CI (1.15-2.89)].Our results suggest that change in LTPA is unrelated to subsequent weight change, but loss in body weight seems related to subsequent more active among female adults.
体力活动与肥胖有关。我们调查了休闲时间体力活动（LTPA）的变化是否预示着随后的体重变化，或者反之亦然。我们使用了丹麦成年人在 1983-1984 年、1987-1988 年和 1993-1994 年进行的纵向研究的数据。在两次连续调查之间，LTPA 的变化被分为无变化、减少或增加活动；体重变化定义为无变化、减轻或增加一个以上的体重指数（BMI）单位。在 2386 名成年人中，LTPA 的变化与随后的体重变化无关。然而，体重减轻（BMI 变化 < -1 单位）与随后的活动减少（OR = 1.49，95%CI（1.03-2.15））或边界上的更活跃（OR = 1.37，95%CI（0.99-1.90））有关。亚组分析表明，女性的特殊性在于，体重减轻与随后的更活跃有关（OR = 1.83，95%CI（1.15-2.89））。我们的结果表明，LTPA 的变化与随后的体重变化无关，但女性的体重减轻似乎与随后的更活跃有关。
