为了解海安县慢性病的流行病学特征，采用分层随机抽样的方法，对５ ８３５名年龄≥３５岁居民的慢性病患病情况进行调查，结果显示：高血压患病率（标化）为２６．９５％，冠心病为１．７４％，脑卒中为０．８１％、糖尿病为０．５４％，恶性肿瘤为１．７５％。该５种疾病的患病率与年龄、职业有关（Ｐ＜０．０５）；高血压、冠心病、脑卒中、糖尿病的患病率与性别。文化程度有关（Ｐ＜０．０５）。表明高血压和恶性肿瘤这２种疾病应是今后海安地区慢性病预防的重点。

The results showed that the prevalence of hypertension was (standardized) 26 .95%, coronary heart disease was 1.74%, stroke was 0.81%, diabetes was 0.54%, malignant tumors was 1.75%. The prevalence of these five diseases was related to age and occupation (P <0.05); the prevalence and gender of hypertension, coronary heart disease, stroke and diabetes. Education level (P <0.05). These two kinds of diseases, hypertension and malignancy, should be the focus of prevention of chronic diseases in Hai’an in the future.
