(n=114657)。为了检验研究的稳定性和普遍性,采用了英国生物银行(UK-Biobank)的一个独立队列重复
了其主要分析(n=499357)。肥胖分级标准为:按BMI分为肥胖(≥30.0 kg/m²)、超重(25.0-29.9 kg/m²)、
正常体重(18.5-24.9 kg/m²)和体重不足(<18.5 kg/m²)。肥胖进一步分为class1(BMI 30·0–34·9
kg/m²)、class2(35·0–39·9 kg/m²)和class3(≥40 kg/m² )。简单共病:同时存在两种肥胖相关性疾病;
复杂共病:同时存在四种及四种以上肥胖相关性疾病。在所有三项队列研究中,根据WHO《国际疾病分类第
10版》(ICD-10)对疾病进行编码。
研究结果
1、研究人群概况(表1):在两个芬兰队列数据中,平均年龄为40.5岁,女性比例为67.4%。在114657名
参与者中体重不足人群为1639人(1.4%)、体重正常人群为62119人(54.2%)、超重人群为29660人
(25.9%)、肥胖人群为21239人(18.5%)。与芬兰队列参与者相比,英国Bio-Bank队列参与者年龄更大,
性别分布更平均,肥胖患病率更高。
