目的探讨成人膳食盐摄入量与肥胖关系。方法于2013年4月采用多阶段整群随机抽样方法抽取徐州市≥18岁常住人口30 572人进行调查。结果 30 572名成年居民平均膳食盐摄入量(14.53±11.04)g/d,超重率为32.17%(9 834/30 572),肥胖率为7.09%(2 169/30 572),中心性肥胖率为45.58%(13 934/30 572);校正潜在的混杂因素后,膳食盐摄入量对肥胖和中心性肥胖的OR值(95%CI)分别为1.467(1.267~1.698)、1.155(1.080~1.234)。结论膳食盐摄入量与肥胖的发生有关联。降低膳食盐摄入量有助于减少肥胖的发生,对居民进行低盐饮食相关健康教育刻不容缓。
Objective To investigate the relationship between dietary salt intake and obesity in adults. Methods In April 2013, a multistage cluster random sampling method was used to survey 30 572 permanent residents ≥ 18 years old in Xuzhou city. Results The average dietary salt intake of 30 572 adult residents was (14.53 ± 11.04) g / d, the rate of overweight was 32.17% (9 834/30 572), the obesity rate was 7.09% (2 169/30 572), central obesity The odds ratio (95% CI) of dietary salt intake to obesity and central obesity were 1.467 (1.267-1.698) and 1.155 (1.080, respectively) after correction for potential confounding factors ~ 1.234). Conclusion Dietary salt intake is associated with the occurrence of obesity. Reducing dietary salt intake helps to reduce the incidence of obesity. It is urgent to educate residents on health education related to low-salt diet.
