柳州市城区居民1996～2001年冠心病行为危险因素的动态监测

Dynamic monitoring of coronary heart disease related behavioral risk factors in residents of Liuzhou urban areas during 1996 to 2001

目的:了解城市人群中冠心病的行为危险因素,为制定康复干预措施和评价防治效果提供信息。方法:1996～2001年,每月采用单纯随机抽样方法,对全市城区范围内年龄在15～69岁的常住居民抽样进行问卷调查,6年间共调查14000人。结果:1996～2001年人群对高血压演变后果、摄入高胆固醇和高盐食品后果的知识知晓率分别上升了4.9%(斜率1.57,P=0.04)、12.7%(斜率3.05,P=0.01)、7.2%(斜率1.85,P=0.02),高血脂和吸烟可导致冠心病的知识知晓率分别上升10.5%(斜率2.29,P=0.01)、4.7%(斜率1.34,P=0.03);35岁以上人群2年内测血压率从51.9%上升到70.1%(斜率3.26,P=0.01)、高血压患者每月定期测血压率从34.8%上升到66.5%(斜率6.64,P=0.00)、40岁以上人群2年内测血脂率从14.9%上升到29.4%(斜率2.81,P=0.00)、人群吸烟率从35.0%下降到28.5%(斜率-1.44,P=0.01),动物内脏摄入显著减少,但超重、肥胖率和静坐生活方式有逐年增加的趋势。结论:人群冠心病相关危险因素知识知晓率显著增加,冠心病相关行为改变也有显著性正向变化,对某些冠心病相关危险因素还应加强干预。

AIM: To understand the behavioral risk factors of coronary heart disease (CHD) among the residents, so as to provide information and baseline data for the intervention and evaluation of the effect of prevention and treatment. METHODS: Totally 14 000 permanent residents aged 15 to 69 years old were selected by the method of randomly sampling monthly in the urban areas of Liuzhou City during 1996 to 2001 to be interviewed by using the questionnaire.RESULTS: The aware rates of hypertension developing outcome, harm of cholesterol and salty food in-take frequently were increased by 4.9%(slope was 1.57, P=0.04), 12.7%(slope was 3.05, P=0.01) and 7.2%(slope was 1.85,P=0.02);aware rates of CHD induced by hyperlipemia and smoking were increased by 10.5%(slope was 2.29, P=0.01) and 4.7%(slope was 1.34, P=0.03) respectively. There were 70.1%of the residents over 35 years old checked their blood pressure every 2 years in 2001 whereas only 51.9%in 1996(slope was 3.26, P=0.01); 66.5%of hypertensive patients checked blood pressure every month in 2001 while only 34.8%in 1996 (slope was 6.64, P=0.00); The rate of checking blood lipid every 2 years among the residents aged over 40 years old was increased from 14.9%to 29.4%(slope was 2.81, P=0.00), while the smoking rate dropped from 35.0%to 28.5%(slope was-1.44, P=0.01). The intake of animal tripe was reduced dramatically, but the rates of overweight, obesity and sedentary life-style were increased gradually.CONCLUSION:The aware rate of the CHD related behavioral risk factors is significantly improved, and the CHD related behavioral changes have significantly positive variation, so intervention measures about CHD related risk factors should be reinforced.
