目的：虽然目前肥胖与身体残疾之间的联系是众所周知的，但肥胖的累积影响尚不清楚。利用健康、老龄化和身体成分研究的数据，我们检验了青壮年和中年体重历史和成年后期体重状况与成年后期体能表现之间的关系。设计：纵向队列研究。研究对象：研究基线(n=2803)的白人和黑人男性和女性(n=2803)。测量：身体质量指数(BMI；kg/m(2))是根据25岁的回忆身高和25岁和50岁的体重以及70-79岁的测量身高和体重计算的。结果：在这个功能良好的队列中，大约24%的男性和8%的女性报告在25岁时超重或肥胖(BMI和GT；=25 kg/m(2))，51%的男性和37%的女性报告在50岁时超重或肥胖，69%的男性和66%的女性在70-79岁时超重或肥胖。年龄在25岁、50岁和70-79岁的肥胖(BMI和Gt；=30 kg/m(2))的男性和女性的SPPB评分和400米步行时间明显低于正常体重的人。在25岁、50岁和70-79岁超重(BMI 25-29.9 kg/m(2))的女性的身体表现也明显较差。此外，那些在25岁或50岁时有超重或肥胖史的男性和女性与那些在70-79岁时体重正常或超重或肥胖但在中年或更早阶段没有超重或肥胖的人相比，身体表现更差。结论：在整个成年期保持健康的体重可能在预防或延缓身体残疾的发生方面发挥作用。
Objective: Although the association between current obesity and physical disability is well known, the cumulative effect of obesity is unknown. Using data from the Health, Aging and Body Composition study, we examined the association between weight history in young and middle adulthood and weight status in late adulthood with physical performance in late adulthood.Design: Longitudinal cohort study.Subjects: White and black men and women aged 70-79 years at study baseline (n = 2803).Measures: Body mass index (BMI; kg/m(2)) was calculated using recalled height at age 25 and weight at age 25 and 50 and measured height and weight at ages 70-79. Physical performance at ages 70-79 was assessed using a short physical performance battery (SPPB) and a 400- m walk test.Results: In this well- functioning cohort, approximately 24% of men and 8% of women reported being overweight or obese (BMI >= 25 kg/m(2)) at age 25, 51% of men and 37% of women reported being overweight or obese at age 50, and 69% of men and 66% of women were overweight or obese at ages 70-79. Men and women who were obese (BMI >= 30 kg/m(2)) at ages 25, 50 and 70-79 had significantly worse SPPB scores and 400- m walk times than those who were normal weight. Women who were overweight (BMI 25-29.9 kg/m(2)) at ages 25, 50 and 70-79 also had significantly worse physical performance. Furthermore, men and women who had a history of being overweight or obese at ages 25 or 50 had worse physical performance compared to those who were normal weight throughout or who were overweight or obese at ages 70-79 but not in midlife or earlier.Conclusions: Maintaining a healthy body weight throughout adulthood may play a role in preventing or delaying the onset of physical disability.
