摘　　要：目的探讨中国成年人盐摄入量与肥胖的关系。方法2017年,采用多阶段整群随机抽样的方法在江苏省和山东省的4个项目点,抽取18~75岁的常住人口,收集24 h尿并进行问卷调查和体格测量。使用多元线性回归和logistic回归的方法分析盐摄入量与肥胖的关联。结果共纳入研究对象1205名,年龄为(49.5±12.6)岁,其中男性564人(46.8%),超重率、肥胖率为42.52%、19.33%,糖尿病、高血压患病率分别为12.94%、45.46%,人均每日盐摄入量为9.32 g/d,其中有84.73%的人日均盐摄入量大于5 g。Logistic回归校正相关混杂因素后,与盐摄入量最低组相比,最高组患肥胖、按腰围(waist circumference,WC)计算的中心性肥胖、按腰围身高比(waist-to-height ratio,WHtR)计算的中心性肥胖的OR(95%CI)值分别为2.64(1.51~4.59)、2.03(1.34~3.09)和1.85(1.20~2.84)。结论盐摄入量与肥胖呈正相关,高盐饮食可能增加肥胖的发病风险。Objective To analyze the association between salt intake and obesity.Methods In 2017,participants aged 18 to 75 years were selected from Jiangsu province and Shandong province by using cluster random sampling method.24 hour urine collection,physical measurement and questionnaire survey were conducted.Logistic regression and multivariate linear regression were used to analyze the association between salt intake and obesity.Results A total of 1205 subjects aged(49.5±12.6)years were included,including 564(46.8%)males.The overweight rate and obesity rate were 42.52%and 19.33%,and the prevalence rates of diabetes and hypertension were 12.94%and 45.46%.The average salt intake was 9.32 g/d,of which 84.73%were more than 5 g.Logistic regression analysis showed that compared with the group in the lowest salt intake,group with the highest salt intake had an increased risk of being obesity,central obesity calculated by waist circumference(WC)and central obesity calculated by waist to height ratio(WHtR)with OR(95%CI)of 2.64(1.51-4.59),2.03(1.34-3.09)and 1.85(1.20-2.84),respectively,after adjusting for relevant factors.Conclusion Salt intake is independently associated with obesity.High salt intake may increase the risk of obesity.
