上海市社区高血压人群左室肥厚的患病率及影响因素

Prevalence and relevant factors on echocardiographic left ventricular hypertrophy among community-based hypertensive patients in Shanghai

目的 了解社区人群左室肥厚的患病率及其影响因素。方法 对上海市南市区高血压人群进行横断面调查。结果 调查高血压人群 16 86人 ,其中男性 978人 ,女性 70 8人。左室肥厚患病率为 2 9.2 % ,男女性分别为 2 5 .4 %和 34.5 % ,女性明显高于男性 (χ2 =16 .17,P <0 .0 1) ,且患病率在两性均随年龄而增加 ,在 4 5～、5 5～、6 5～岁年龄段男女性别之间左室肥厚的患病率差异均有显著性 (P <0 .0 5 )。单因素及多因素分析结果表明性别、年龄、文化程度、体重指数、收缩压均是左室肥厚的影响因素 ,其中文化程度为保护性因素。结论 社区中老年人左室肥厚的患病率高 ,与多种复杂因素有关 ,应从多方面对这些因素进行针对性防治。

Objective To investigate the prevalence and relevant factors on the echocardiographic left ventricular hypertrophy (LVH). Method A cross sectional study was conducted among the hypertensive patients in an urban community. Results The prevalence of LVH was 29.2 % in 1 686 hypertensive patients, with 25.4 % in males and 34.5 % in females, respectively. The prevalence was significantly higher in females than in males(χ 2= 16.17 , P < 0.01 ). The rate was increasing with age and significantly higher prevalence was observed in 45 ,55 ,65 age groups of females ( P < 0.05 ). Moreover, elevated systolic blood pressure and higher BMI were related to the LVH in hypertensive patients, while higher education level seemed a protective factor. Conclusion These results implied that a comprehensive intervention should be taken in the prevention of LVH.
