农村中老年人高血压患病率与体质量指数的关系探讨

为探讨农村中老年人高血压患病率与体质量指数 (BMI)的关系 ,对 5 3 4名 5 0～ 69岁健康农村中老年人的血压、身高、体质量进行测量 ,并计算BMI,按不同年龄、性别、BMI进行分组 ,分析高血压患病情况。结果显示男性肥胖组 (BMI≥ 2 5 )的高血压患病率 (5 5 .3 % ) ,明显高于正常组 (BMI 1 8.5～ 2 4.9,3 2 .3 % )及体质量较轻组 (BMI<1 8.5 ,3 1 .4% ,P <0 .0 5 ) ;女性肥胖组患病率 (5 6.3 % )明显高于BMI正常组 (3 1 .3 % )及体质量较轻组 (2 5 .8% ,P <0 .0 5 )。提示肥胖是影响高血压患病率的重要因素 ,建议通过控制体质量预防高血压。

Relationship between BMI and Prevalence Rate of Hypertension of Middle and Elderly Rural Residents in China

To study the relationship between BMI and the prevalence rate of hypertension, the blood pressue, weight and height of 534 people from ruralarea, aged 50～69 years were measured with standardized methods and under strict quality control. The investigated people were grouped by age、sex and BMI. The prevalence rate(55.3%)of hypertension for the obesity group(BMI≥25)was obviously higher than the normal group(BMI=18.5～24.9, 32.3%)and the light body weight group(BMI<18.5, 31.4%, P<0.05)for male. For female, the prevalence rate of hypertension obesity group(56.3%)was obviously higher than that of the normal group(31.3%)and the light body weight group(25.8 %, P< 0.05). Obesity is an important factor resulting in hypertension, and hypertension should be prevented by controlling the body weight.
