The ethnic and sex differences in the distributions of body mass index (BMI) and waist circumference (WC) among adults are largely unknown. Therefore, we aimed to investigate the percentiles of BMI and WC in groups divided according to age, sex, and ethnicity.
We conducted a population-based binational study of adults aged ≥20 years based on data from two sources: US National Health and Nutrition Examination Survey (2015 to 2020) and Korea National Health and Nutrition Examination Survey (2016 to 2019).
Weight, height, and WC were measured in 13,144 American adults and 30,191 Korean adults. Overall, BMI increased at younger ages and decreased at older ages, which indicates a reversed U-shaped relationship, and differed in terms of age, sex, and ethnicity. Women in the other Hispanic, non-Hispanic white, non-Hispanic black, and "other ethnic groups" showed a common BMI peak at ages 50-54 years. The patterns of WC distribution were similar to those of BMI distribution.
In this binational representative study, we found varied distributions of ethnic and sex differences in BMI and WC. Considering the differences in these distributions may help improve individual and personalized treatment strategies.
成年人的体重指数（BMI）和腰围（WC）在种族和性别分布上存在很大差异，但目前对此知之甚少。因此，我们旨在根据年龄、性别和种族对成年人进行分组，调查 BMI 和 WC 的百分位数。
我们进行了一项基于两项来源数据的成人（年龄≥20 岁）的基于人群的跨国研究：美国国家健康和营养检查调查（2015 年至 2020 年）和韩国国家健康和营养检查调查（2016 年至 2019 年）。
美国 13144 名成年人和韩国 30191 名成年人接受了体重、身高和 WC 的测量。总体而言，BMI 随年龄增长而增加，随年龄增长而减少，呈倒 U 型关系，且在年龄、性别和种族方面存在差异。其他西班牙裔、非西班牙裔白种人、非西班牙裔黑人和“其他种族群体”的女性在 50-54 岁时 BMI 达到峰值。WC 分布模式与 BMI 分布模式相似。
在这项跨国代表性研究中，我们发现 BMI 和 WC 的种族和性别差异分布存在差异。考虑到这些分布的差异，可能有助于改善个体化和个性化的治疗策略。
