目的：研究的体重增加率随着时间的推移在美国人的年龄，性别，和race.PARTICIPANTS：科学样本的5117美国人，年龄25-74 y在1971年，随后为20 y.RESULTS：混合效应模型估计的体重增加率是最高的年轻人和体重减轻率是最大的老年人。就体重增加和减轻而言，男性和女性、黑人和白色的生长曲线的总体形状相似。肥胖率也受基线体重指数（BMI =体重（kg）/身高（m2））的影响。结论：美国人的体重增加直到中年，稳定下来，并在60岁左右开始减肥。老年时期的体重减轻对肥胖的美国人来说尤其明显。准确识别风险增加的群体并针对他们进行肥胖预防的能力将有助于对抗美国超重和肥胖的稳步上升。
OBJECTIVE: To examine the rate of weight gain over time among Americans by age, gender, and race.PARTICIPANTS: Scientific sample of 5117 Americans, ages 25-74 y in 1971 followed for 20 y.RESULTS: Rates of weight gain estimated by mixed effects models are highest among young adults and rates of weight loss are greatest among older adults. The overall shape of the growth curves are similar for men and women, black and white, in terms of both weight gain and weight loss. Rates are also affected by baseline body mass index (BMI = wt in kg/height in m(2)).CONCLUSIONS: Americans gain weight until middle age, stabilize, and begin to lose weight near age 60. Weight loss during old age is especially evident for obese Americans. The ability to accurately identify groups with increased risk and target them for obesity prevention will help combat the steady rise of overweight and obesity in America.
