【摘要】 目的了解广西白裤瑶族中老年人群的血压及其影响因素。方法采用分层随机整群抽样方法,对485例白裤瑶族中老年人群的血压、饮食和生活方式等进行流行病学调查,另选501例当地的汉族人群进行比较。结果白裤瑶族人群的体力活动、碳水化合物和膳食纤维摄入量高于汉族人群,而受教育水平、身高、腰围、体重、体重指数、总能量、总脂肪、蛋白质、胆固醇和钠盐摄入量则低于汉族人群;白裤瑶族人群的收缩压、舒张压、脉压和高血压患病率低于汉族人群(P<0.05,P<0.01)。两民族人群高血压与年龄、体力活动、体重指数、腰围、总能量,总脂肪和钠盐摄入量呈正相关,与教育水平和总食物纤维摄入量呈负相关(P<0.05,P<0.01);此外,白裤瑶族人群高血压还与甘油三酯呈正相关,汉族人群高血压与饮酒呈正相关(P<0.05)。结论白裤瑶族和汉族人群的血压水平及其危险因素存在差异,可能与他们的饮食结构、生活方式、体力活动、钠盐摄入和遗传因素不同有关。更多还原

【Abstract】 Objective To investigate the blood pressure level and its risk factors for the middleaged and elderly Guangxi Bai Ku Yao population. Methods A total of 485 subjects of Bai Ku Yao nationality aged 40 and over were surveyed by a cluster sampling method. Information on demographic characteristics,dietary intake, and other lifestyle factors was collected by standard questionnaires. Blood pressure, height,weight, waist circumference, serum lipids and apolipoproteins were measured, and body mass index(BMI) was calculated. The results were compared with those in 501 subjects of Han Chinese from the same villages. Results Physical activity level,carbohydrate and dietary fiber intakes were higher in Bai Ku Yao than in Han,whereas educational level, height, weight, BMI, waist circumference, and total energy, dietary total fat, protein, cholesterol and salt intakes were higher in Han than in Bai Ku Yao. Systolic,diastolic and pulse pressure levels,and the prevalence of hypertension were lower in Bai Ku Yao than in Han. Hypertension was positively correlated with age, physical activity, BMI, waist circumference, total energy, total fat and salt intakes, and negatively correlated with educational level and dietary fiber intake in both ethnic groups (P<0.05, P<0.01). In addition, hypertension was also positively correlated with triglycerides in Bai Ku Yao,and with alcohol consumption in Han (P<0.05). Conclusions The differences in blood pressure and the risk factors between Bai Ku Yao and Han might result from different dietary patterns,lifestyles,physical activity levels,sodium intake,and genetic factors.更多还原
