The primary objective of the present investigation was to identify 10-year weight gain patterns in 13,802 US adults and also to determine the extent that differences in 10-year weight gains were associated with the key demographic variables: age, sex, and race.
The study design was cross-sectional and included the years 2011-2018. Data for 2019-2020 were not available because of COVID. A multistage random sampling strategy was employed. Specifically, individual sample weights and randomly selected clusters and strata were used with each statistical model, allowing the results to be generalized to the US adult population.
Mean (±SE) 10-year weight gain was 4.2 ± 0.2 kg or 6.6 ± 0.2% of initial body weight. A total of 51% of the participants gained 5% or more body weight, 36% gained 10% or more, and 16% gained 20% or more across the 10-years. Age was linearly and inversely associated with 10-year weight gain, expressed in kg ( = 166.4, < 0.0001) or percent weight gain ( = 246.9, < 0.0001), after adjusting for sex and race. For each 1-year increase in age, 10-year weight gain decreased by 0.20 ± 0.02 kg and 0.28 ± 0.02 percent. After adjusting for age and race, 10-year weight gain (kg) was significantly greater ( = 73.6, < 0.0001) in women (5.4 ± 0.3) than in men (2.6 ± 0.2). Weight gain also differed across races, kg ( = 27.7, < 0.0001) and % ( = 28.5, < 0.0001). Non-Hispanic Blacks gained more weight and NH Asians gained less weight than the other races.
Without question, 10-year weight gain is a serious problem within the US adult population. Younger adults, women, and Non-Hispanic Blacks, particularly Black women, seem to experience the highest levels of 10-year weight gain. Consequently, obesity and weight gain prevention programs focusing on these at-risk individuals should be a public health priority.
本研究的主要目的是确定 13802 名美国成年人 10 年内的体重增长模式，并确定体重增长差异与关键人口统计学变量（年龄、性别和种族）之间的关联程度。
本研究采用了横断面研究设计，包括 2011-2018 年的数据。由于 COVID-19 的影响，2019-2020 年的数据不可用。采用多阶段随机抽样策略。具体来说，每个统计模型都使用个体样本权重和随机选择的群集和层，使结果可以推广到美国成年人群体。
10 年内体重平均（±SE）增加 4.2±0.2kg 或初始体重的 6.6±0.2%。共有 51%的参与者体重增加了 5%或更多，36%的参与者体重增加了 10%或更多，16%的参与者体重增加了 20%或更多。年龄与 10 年内体重增加呈线性反比关系，以公斤（ = 166.4， < 0.0001）或体重增加百分比（ = 246.9， < 0.0001）表示，在调整性别和种族因素后。每增加 1 岁，10 年内体重增加量减少 0.20±0.02kg 和 0.28±0.02%。在调整年龄和种族因素后，女性（5.4±0.3kg）10 年内体重增加量明显大于男性（2.6±0.2kg）（ = 73.6， < 0.0001）。体重增加也因种族而异，公斤（ = 27.7， < 0.0001）和%（ = 28.5， < 0.0001）。非西班牙裔黑人的体重增加量高于其他种族，而非西班牙裔亚裔的体重增加量则低于其他种族。
毫无疑问，10 年内体重增加是美国成年人群体中的一个严重问题。年轻成年人、女性和非西班牙裔黑人，尤其是黑人女性，似乎经历了最高水平的 10 年内体重增加。因此，关注这些高风险人群的肥胖和体重增加预防计划应成为公共卫生的重点。
