There are important and understudied health differences among subgroups of Asian Americans. The authors examined differences in BMI percentile and body weight status among Asian American youth.
The authors conducted a retrospective cohort study using electronic health records in 2011-2020 from 2 integrated healthcare systems in California. Single-race, non-Latino White, and Asian American youth aged 2-19 years during the study period were included. Asian American subgroups included East, South, Southeast, and unidentified. Whites were the reference group. Study outcomes included age- and sex-specific BMI percentile and body weight status category (underweight, overweight or obesity, obesity). Series of 1-sample estimates for study outcomes were calculated by calendar year and biological ages.
A total of 395,134 youth were included in the study (mean [SD] age at baseline of 8.26 [5.61] years; mean [SD] BMI percentile of 53.8 [30.3]), including 23,183 East Asians; 34,783 South Asians; and 34,738 Southeast Asians. Southeast Asians had the highest age-adjusted prevalence of obesity (2019 estimate: 13.3%) than East Asians (5.2%), South Asians (7.8%), and Whites (11.8%). South Asians had the highest prevalence of underweight (2019 estimate: 11.8%) than East Asians (5.5%), Southeast Asians (3.9%), and White (3.6%).
Substantial heterogeneity among Asian American youth was found in the study cohort. Asian American youth face distinct challenges of unhealthy weight statuses unique to their subgroups.
亚裔美国人亚组之间存在重要且研究不足的健康差异。作者研究了亚裔美国青少年在BMI百分位数和体重状况方面的差异。
作者进行了一项回顾性队列研究，使用了2011年至2020年加利福尼亚州2个综合医疗系统的电子健康记录。纳入了研究期间年龄在2至19岁的单一种族、非拉丁裔白人和亚裔美国青少年。亚裔美国亚组包括东亚、南亚、东南亚和身份不明者。白人作为参照组。研究结果包括特定年龄和性别的BMI百分位数以及体重状况类别（体重过轻、超重或肥胖、肥胖）。按日历年和生物学年龄计算研究结果的一系列单样本估计值。
该研究共纳入395,134名青少年（基线时的平均[标准差]年龄为8.26[5.61]岁；平均[标准差]BMI百分位数为53.8[30.3]），其中包括23,183名东亚人；34,783名南亚人；以及34,738名东南亚人。东南亚人的肥胖年龄调整患病率最高（2019年估计值：13.3%），高于东亚人（5.2%）、南亚人（7.8%）和白人（11.8%）。南亚人的体重过轻患病率最高（2019年估计值：11.8%），高于东亚人（5.5%）、东南亚人（3.9%）和白人（3.6%）。
在该研究队列中发现亚裔美国青少年存在显著的异质性。亚裔美国青少年因其亚组的不同而面临独特的不健康体重状况挑战。
