新疆维吾尔自治区汉族、维吾尔族、哈萨克族右束支阻滞流行病学调查及患病率研究

Prevalence and distribution feature of right bundle branch block in Xinjiang adult population

目的了解新疆维吾尔自治区成年人右束支阻滞（fightbundlebranchblock，RBBB）的患病率、分布特征及合并其他心血管疾病的情况。方法应用四阶段整群随机抽样法，在全疆7个地区抽取年龄在35岁以上样本。结果共抽取14618人，RBBB患病率为1．40％；其中汉族为1．60％，维吾尔族为1．50％，哈萨克族为1．00％。男性患病率高于女性（x2=22．00，P〈0．01）。35～44岁、45～54岁、55～64岁、65～74岁、75岁以上各年龄组RBBB患病率依次为0．70％、1．00％、1．80％、2．90％、4．70％。RBBB患者中合并超重或肥胖者占65．20％，高血压者占50．98％，糖尿病者占13．24％，冠心病者占10．78％，心室肥厚占0．50％。结论新疆维吾尔自治区RBBB患病率随年龄增加呈递增趋势，且存在性别和民族差异。RBBB患者主要合并症是超重、肥胖、及高血压。

Objective To investigate the prevalence and distribution feature of right bundle branch block （RBBB） as well as the prevalence of other cardiovascular diseases in patients with RBBB in Xinjiang adult population. Methods Four-stage selected random samples age 35 and over were ended up. The sampled adults were collected from 7 localities in Xinjiang. Results A total of 14 618 adults were surveyed. The preva- lence of RBBB was 1.60% , 1.50% and 1.00% in Han, Uygur and Kazak population, respectively. The prev- alence of RBBB in females was lower than in males （X2 = 22. 00, P 〈 0. 01 ）. The prevalence of RBBB was 0. 70% ,1.00% ,1.80% ,2. 90% and 4. 70% in 35-44, 45-54, 55-64, 65-74, and over 75 age groups, re- spectively. RBBB was along with overweight or obesity （ 65.20% ） , hypertension （ 50. 98% ）, diabetes （ 13.24% ）, coronary heart disease （ 10. 78% ） and ventricuiar hypertrophy （ 0. 50% ）. Conclusions The prevalence of RBBB shows consecutive upward trend with the increasing of age. The prevalence of RBBB is dif- ferent among ethnics and different between males and females. The main cardiovascular diseases in patients with RBBB are over weight, obesity and hypertension.
