壶关县农村居民高血压患病及膳食摄入与其关系的非条件Logistic分析

[目的]探讨农村居民食物摄入水平与高血压的关系，对农村居民开展高血压的膳食防治提供参考依据。[方法]2006年7月，对壶关县石河末村25岁以上农村常住居民进行食物频率调查和血压测量，并对食物摄人量与高血压患病关系进行多因素非条件Logistic回归分析。[结果]调查1256人，高血压患病率为23．96％。高血压患病率，男性为26．10％，女性为21．92％（P〉0．05）；男性与女性均为≥45岁高于〈45岁（P〈0．01）；〈45岁男性高于女性（P〈0．05），≥45岁男性与女性的差异无统计学意义（P〉0．05）。非条件Logistic回归分析结果，进入回归模型的食物因素有腌制蔬菜摄入量（OR=1．28）、油脂类食物摄入量（OR=1．06）、新鲜蔬菜水果摄入量（OR=0．72）。[结论]石河末村25岁以上农村常住居民高血压患病率处于一般水平。腌制蔬菜、油脂类食物摄入量多是高血压的危险因素，新鲜蔬菜水果摄入量多是高血压的保护因素。

Unconditioned Logistic Analysis of Hypertension and the Relationship with Dietary Intake among Rural Population in Huguan County

[Objective]To understand the relation between dietary intakes and hypertension, provide reference for prevention and dietary instruction of hypertension among rural population. [Methods]The people over 25 years old in Shihc mo village of Huguan county included in the survey in July,2006. The questionnaire about dietary frequency and the blood pressure measure were done. unconditioned. logistic regression analysis was adopted to analyze the relation between dietary intakes and hypertension. [Results]A total of 1 256 people included in the survey. The prevalence rate of hypertension among rural population in Huguan County was 23.69%. The prevalence rate of hypertension among male was 26.10% and female was 21.92% （ P 〉0.05） The prevalence rate of hypertension among people（≥45 years old） was higher than those （G45 years old） （ P 〈0.01）. The prevalence rate of hypertension in male（G45 years old） was higher than those in female （G45 years old）（ P 〈0.05）. There was no statistical significance between male and female（≥45 years old） in the prevalence rate of hypertension（ P 〉0.05）. The results of unconditioned logistic regression analysis indicated that among factors entering the regression model were the salted vegetables intake（ OR = 1.28）, rich-fat food intake（ OR = 1.06） and the fresh vegetables intake （ OR = 0.72）. [Conclusion]The prevalence rate of hypertension among the people in Shihemo village was at a common level. More intake of the salted vegetables and rich-fat food were the risk factors of hypertension. More intake of the fresh vegetables was the protective factor of hypertension.
