西安市居民膳食磷摄入与高血压罹患的关联性研究

The Association Between Dietary Phosphorus Intake and Hypertension Among Residents of Xi'an City

目的:研究西安市居民膳食磷摄入状况及其与高血压罹患的相关关系,为制定高血压综合防治策略提供科学依据。方法:于2019年1月调查西安市某社区18岁以上在该地居住6个月以上的居民共1474人,采用健康危险因素问卷和膳食频率调查表获取个人基本信息、膳食磷摄入及高血压患病情况。通过单因素分析和多因素Logistic回归模型,探讨膳食磷摄入和高血压患病的影响因素及相互关联。结果:西安市成年人高血压患病率为27.1%,其中男性为30.9%、女性为22.7%。调查对象膳食总能量和磷的日均摄入量分别为(2260.1±866.0)kcal/d和(1404.1±646.2)mg/d。性别、文化程度、家庭人均月收入、体重指数(BMI)和饮酒均会影响高血压患病和膳食磷日均摄入量。多因素回归分析结果显示,调整以上混杂因素及膳食因素后,膳食磷摄入与高血压罹患风险正相关,磷摄入最高分位组的高血压患病风险是最低摄入组的1.86(95%CI:1.01~3.46)倍。结论:西安市成人膳食磷摄入量与高血压罹患风险的增加相关,适量降低膳食磷摄入量对高血压防治具有重要意义。

[Objective] To investigate the association of dietary phosphorus intake and hypertension in residents of Xi'an city,thereby providing scientific evidence for prevention of hypertension.[Method] Totally 1474 subjects(≥18 years old)were surveyed from a community in January of 2019,who have stayed for more than 6 months in Xi'an city.Personal information,dietary phosphorus intake,and prevalence of hypertension were collected using questionnaire investigation of health risk factors and quantitative food-frequency.Univariate analysis and Multivariate Logistic Regression Model were used to evaluate the association between dietary phosphorus intake and hypertension.[Result] The morbidity of hypertension among adults was 27.1%(30.9%for males and 22.7%for females).Dietary total energy and phosphorus intake were(2260.1±866.0)kcal/d and(1404.1±646.2)mg/d,respectively.Gender,education,monthly household income,body mass index(BMI),and alcohol consumption influenced hypertension and the daily intake of dietary phosphorus(P<0.05).In multivariate logistic regression models with adjustment for confounding factors,dietary phosphorus intake was positively correlated with the risk of hypertension.The risk of hypertension in the highest phosphorus intake group was 1.86(95%CI:1.01~3.46)times that of the lowest intake group.[Conclusion] The intake of dietary phosphorus is associated with an increased risk of hypertension.The proper reduction of dietary phosphorus intake might help the prevention and treatment of hypertension.
