上海市社区高血压人群左室肥厚的患病率及影响因素

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1686人，其中男性978人，女性708人，左室肥厚患病率为29．2％，男女性分别为25．4％和34．5％，女性明显高于男性（X^2＝16．17，P＜0．01），且患病主在两性均随年龄而增加，在45－、55－、65－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＜0．05）。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度的影响因素，其中文化程度为保护性因素。结论：社区中老年人左室肥厚度的患病率高，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。

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

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 (chi(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.
