广西成人体重异常的影响因素分析

Analysis on Relative Influencing Factors of Abnormal Weight in Guangxi

目的了解广西成人BMI(体重指数)异常的影响因素,掌握广西成人肥胖的流行状况,为肥胖防治提供科学依据。方法采用分层整群随机抽样的方法,对广西的东、西、南、北、中部地区的城市和农村≥18岁常住人口开展糖尿病流行病学横断面调查,取其中有身高、体重、腰围等完整资料的18岁以上的34 737人列入本次分析。结果广西成人超重率、肥胖率分别为31.30%、6.90%,标化率分别为15.98%、3.28%。无序多分类Logistic回归分析发现,影响体重过低的因素是舒张压(DBP)、空腹血糖(FBS)、三酰甘油(TG)等;影响超重的因素是HDL、LDL、吸烟等;影响肥胖的因素是HDL、LDL、HOMA-β等。结论广西成人超重和肥胖率较以往有所上升,处于国内较高水平;体重异常情况不同,影响因素也不同,应加大健康宣教力度,维持广西居民的健康体重。
