To evaluate how a change in the level of leisure-time physical activity from adolescence into adulthood is associated with overall and abdominal obesity at the age of 31 y.
Prospective follow-up study of Northern Finland birth cohort of 1966.
In all, a population of 2834 males and 2872 females aged 31 y was studied.
At the age of 31 y, overweight was defined as a body mass index (BMI) of 25.0-29.9 kg/m(2) and obesity as a BMI of 30.0 kg/m(2) or more. The cutoff points of waist circumference for mild and severe abdominal obesity were 94.0 and 102.0 cm in males and 80.0 and 88.0 cm in females. The change in the level of physical activity (at least moderately active vs inactive) was evaluated by inquiries conducted at the ages of 14 and 31 y. The odds ratios (OR) and their 95% confidence intervals (CI) obtained from logistic regression were adjusted for maternal BMI before pregnancy, BMI at the age of 14 y, alcohol intake, occupational physical activity, smoking, and, in the case of females, for parity at age 31 y.
Becoming inactive during the transition from adolescence to adulthood was associated with overall overweight in males (OR 1.49, CI 1.18-1.89), overall obesity in males (OR 1.53, CI 0.99-2.37) and females (OR 1.51, CI 0.94-2.44), and with severe abdominal obesity in females (OR 1.80, CI 1.13-2.86). Being persistently inactive from adolescence to adulthood was associated with mild abdominal obesity in males (OR 1.83, CI 1.13-2.95), but not with other obesity measures in either gender after adjustment for confounding factors.
Becoming inactive during the transition from adolescence to adulthood is related to overall obesity in both genders, and to severe abdominal obesity in females at the age of 31 y. The results emphasize the role of continued physical activity from adolescence into adulthood in the prevention of adult obesity.
评估从青春期到成年期休闲时间身体活动水平的变化与31岁时总体肥胖和腹部肥胖的关联。
对1966年芬兰北部出生队列进行前瞻性随访研究。
共研究了2834名31岁男性和2872名31岁女性。
31岁时，超重定义为体重指数（BMI）为25.0 - 29.9 kg/m²，肥胖定义为BMI为30.0 kg/m²或更高。男性轻度和重度腹部肥胖的腰围切点分别为94.0和102.0 cm，女性分别为80.0和88.0 cm。通过在14岁和31岁时进行的询问来评估身体活动水平的变化（至少中度活跃与不活跃）。从逻辑回归中获得的比值比（OR）及其95%置信区间（CI）针对孕前母亲BMI、14岁时的BMI、酒精摄入量、职业身体活动、吸烟情况进行了调整，对于女性还针对31岁时的产次进行了调整。
从青春期到成年期变得不活跃与男性总体超重（OR 1.49，CI 1.18 - 1.89）、男性总体肥胖（OR 1.53，CI 0.99 - 2.37）和女性总体肥胖（OR 1.51，CI 0.94 - 2.44）以及女性重度腹部肥胖（OR 1.80，CI 1.13 - 2.86）相关。从青春期到成年期持续不活跃与男性轻度腹部肥胖（OR 1.83，CI 1.13 - 2.95）相关，但在调整混杂因素后，与两性的其他肥胖指标均无关。
从青春期到成年期变得不活跃与两性的总体肥胖以及31岁女性的重度腹部肥胖有关。研究结果强调了从青春期到成年期持续进行身体活动在预防成人肥胖中的作用。
