Comparison of criteria for metabolically healthy overweight/obesity in Shanghai Changfeng study / 中华内科杂志

ABSTRACT

Objective:To establish a more suitable and practicable criterion of metabolically healthy overweight/obesity (MHO/O) in Chinese, a comparison study on different criteria of MHO/O was conducted in subjects aged over 45-year-old in Shanghai Changfeng Community.Method:A total of 3 301 overweight/obese subjects over 45 years old (men 1 521, women 1 789) in Shanghai Changfeng Community was included in the study. According to the inclusion or exclusion of waist circumference (WC), homeostasis model assessment of insulin resistance (HOMA-IR) ≥2.5, and numbers of abnormal metabolic components, the MHO/O criteria were divided into 7 types Adult Treatment Panel Ⅲ (ATP-Ⅲ) (with WC)<1 component, ATP-Ⅲ (with WC)<2 components, ATP-Ⅲ (with WC)<3 components, ATP-Ⅲ (without WC)<1 component, ATP-Ⅲ (without WC)<2 components, adjusted metabolic associated fatty liver disease (MAFLD) criteria<1 component, and adjusted MAFLD criteria<2 components. The prevalence of MHO/O and its relationship with the changes of body mass index (BMI), and the differences of the characteristics of MHO/O among the 7 types of metabolic health standards were compared.Result:The prevalence of MHO/O according to the ATP-Ⅲ (with WC)<1, ATP-Ⅲ (with WC)<2, ATP-Ⅲ (with WC)<3, ATP-Ⅲ (without WC)<1, ATP-Ⅲ (without WC)<2, adjusted MAFLD criteria<1, and adjusted MAFLD criteria<2 was 2.85%, 15.48%, 39.87%, 8.00%, 33.66%, 2.33%, 12.24%, respectively. The prevalence of MHO/O decreased as BMI increased. When BMI ≥ 28 kg/m 2, the prevalence of MHO/O by ATP-Ⅲ (with WC)<1 and adjusted MAFLD criteria<1 dropped to 0. Conclusion:The adjusted MAFLD criterion without abnormal metabolic components is the most practicable definition of MHO/O.
