目的探讨新疆地区居民代谢健康型肥胖(MHO)的患病率及影响因素。方法 2015年至2016年期间,采用分层多阶段随机抽样,选取新疆地区35~80岁调查对象4627人,有效数据3456(74.69%)人。肥胖和代谢状态分类基于体质指数(BMI)和代谢异常组分的数量。结果调查人群中MHO患病率为16.09%,肥胖人群MHO患病率为59.15%。女性中MHO比例随着年龄增加而下降(P<0.01),男性中未见该趋势(P>0.05)。农村居民MHO比例显著高于城市(64.75%vs.43.27%,P<0.01)。汉族(OR=0.33,95%CI:0.23~0.45)、腰围(WC)增加(每5cm)(OR=0.80,95%CI:0.73~0.88)与MHO患病风险下降相关,中度职业体力劳动(OR=2.92,95%CI:1.75~4.88)与MHO患病风险增加相关。调整内脏脂肪指数(VFI)模型中,VFI升高(OR=0.80,95%CI:0.73~0.88)与MHO患病风险下降相关。结论新疆地区35~80岁居民MHO患病率较高。年龄、民族、中度职业劳动强度、WC和VFI与肥胖人群的代谢状态有关。
Objective To investigate the prevalence and influential factors of metabolic health-type obesity (MHO) in Xinjiang region. Methods From 2015 to 2016, stratified multistage random sampling was used to select 4627 people aged 35-80 years in Xinjiang, with 3456 (74.69%) valid data. The classification of obesity and metabolic status is based on the body mass index (BMI) and the number of metabolic abnormalities components. Results The prevalence of MHO in the surveyed population was 16.09%, and the prevalence of MHO in obese people was 59.15%. The proportion of women with MHO decreased with increasing age (P <0.01), but not in males (P> 0.05). The MHO proportion of rural residents was significantly higher than that of urban areas (64.75% vs.43.27%, P <0.01). Han (OR = 0.33, 95% CI: 0.23-0.45), increased WC (every 5cm) (OR = 0.80,95% CI: 0.73-0.88) were associated with a decreased risk of MHO, moderate occupational manual labor (OR = 2.92, 95% CI: 1.75-4.88) were associated with an increased risk of MHO. Elevated VFI (OR = 0.80, 95% CI: 0.73 to 0.88) was associated with a decreased risk of MHO in the adjusted visceral fat index (VFI) model. Conclusion The prevalence of MHO in 35 ~ 80-year-old residents in Xinjiang is higher. Age, ethnicity, moderate occupational labor intensity, WC and VFI are related to the metabolic status of obese people.
