The use of universal body mass index (BMI) cutoffs do not take into account variation in the association between BMI and health risk across diverse ethnic groups. We used the New Zealand Health Survey data collected between 2002/2003 and 2014/2015 to calculate the predictive marginal means of hypertension, cardiovascular diseases, and type 2 diabetes mellitus (T2DM) after adjusting for demographic variables and health-related behaviors. Compared with European group, we found that Pacific had a lower prevalence of hypertension at a BMI of ≥35 kg/m, and Māori had a higher prevalence of hypertension, T2DM, and cardiovascular diseases at higher BMI intervals. Whereas Asian had a higher T2DM prevalence compared with Māori, Pacific, and European at some BMI intervals. Using universal BMI cutoffs on the ethnically diverse population to compare obesity rates does not address the risk of chronic diseases associated with high BMI and may stigmatize certain ethnic groups.
使用通用的身体质量指数 (BMI) 切点并不能考虑到 BMI 与不同种族群体的健康风险之间的关联在不同人群中的变化。我们使用了 2002/2003 年至 2014/2015 年期间收集的新西兰健康调查数据，在调整了人口统计学变量和与健康相关的行为后，计算了高血压、心血管疾病和 2 型糖尿病 (T2DM) 的预测边缘均值。与欧洲组相比，我们发现太平洋族群在 BMI≥35kg/m2 时高血压的患病率较低，而毛利人在更高的 BMI 区间时高血压、T2DM 和心血管疾病的患病率较高。而亚洲族群在某些 BMI 区间时，T2DM 的患病率高于毛利人、太平洋族群和欧洲族群。在种族多样化的人群中使用通用的 BMI 切点来比较肥胖率，并不能解决与高 BMI 相关的慢性疾病风险，并且可能会给某些族群带来污名化。
