摘要
目的:分析每日膳食钾摄入量与代谢综合征(MS)的关系。方法:纳入2015年3月至2019年3月2 248名在扶风县人民医院体检者为研究对象,使用连续3 d持续24 h膳食回顾法获得个人膳食钾的摄入量。同时进行体格检查和清晨空腹血样采集,根据膳食钾摄入量(mg/d)分为亚组,使用多因素 logistic回归分析,探讨膳食钾摄入量与MS的相关性。 结果:所有调查对象平均每日膳食钾摄入量为(2 432.87±31.43) mg,男性显著高于女性( t=30.281, P=0.000)。男性吸烟比例、饮酒比例、腰围、总胆固醇、低密度脂蛋白-胆固醇、高密度脂蛋白-胆固醇水平显著高于女性( χ^2=467.068、478.304;t=16.726、14.844、4.313、5.267, P均<0.05);而女性MS患病率、腹型肥胖比例、高血压、糖尿病、高甘油三酯血症、低高密度脂蛋白-胆固醇血症及甘油三酯水平显著高于男性( χ^2=4.700、12.005、30.280、5.170、5.946、3.543, t=6.116, P均<0.05)。 Logistic回归分析显示,男性调查对象的每日膳食钾摄入量和MS发病率间无显著相关关系( OR=1.38,95% CI: 0.68~2.79, P=0.364)。当女性调查对象每日膳食钾摄入量少于3 600 mg时,每增加1 000 mg/d,其MS发病风险降低12%( OR=0.88, 95% CI: 0.83~0.98, P=0.002)。每日膳食钾摄入量增加时,MS的5个组成因素(腹型肥胖、高血糖、高血压、高甘油三酯血症、低高密度脂蛋白-胆固醇血症)的发生均显著下降( χ^2=75.02、22.09、146.00、25.54、14.68, P均<0.05),平均每个患者所患MS组成因素个数也显著减小( F=3 119, P=0.000)。 结论:每日膳食钾摄入量与女性MS的发病风险呈负相关,高钾膳食是MS的保护因素。
Objective To analyze the relationship between daily dietary potassium intake and metabolic syndrome(MS).Methods A total of 2248 eligible participants in the examination center of Fufeng County People′s Hospital from March 2015 to March 2019 were enrolled in this survey.Individual dietary potassium intake was obtained using a continuous 3 d continuous 24 h dietary review method.Physical examination and fasting blood samples were collected at the same time,and the correlation between daily dietary potassium intake and MS was analyzed using multivariate logistic regression analysis.Results The average dietary potassium intake of all the respondents was(2432.87±31.43)mg/d,which was significantly higher in men than that in women(t=30.281,P=0.000).The smoking ratio,drinking ratio,waist circumference,total cholesterol,low-density lipoprotein-cholesterol and high density lipoprotein-cholesterol in men were significantly higher than those in women(χ^2=467.068,478.304;t=16.726,14.844,4.313,5.267,all P<0.05).The prevalence of MS,the proportion of abdominal obesity,hypertension,diabetes,hypertriglyceridemia,low-density lipoprotein-cholesterol and triglyceride levels in women were significantly higher than those in men(χ^2=4.700,12.005,30.280,5.170,5.946,3.543;t=6.116,all P<0.05).Logistic regression analysis showed that there was no significant correlation between daily dietary potassium intake and the incidence of MS among male respondents(OR=1.38,95%CI:0.68-2.79,P=0.364).When the female subject′s daily dietary potassium intake was less than 3600 mg,each increased intake of 1000 mg/d reduced the risk of MS by 12%(OR=0.88,95%CI:0.83-0.98,P=0.002).When daily dietary potassium intake increased,the incidence of the five constituent factors of MS(abdominal obesity,hyperglycemia,hypertension,hypertriglyceridemia and low high-density lipoprotein-cholesterol)decreased significantly(χ^2=75.02,22.09,146.00,25.54,14.68,all P<0.05),the number of MS constituents per patient also decreased significantly(F=3119.00,P=0.000).Conclusi
