| Background and purpose:Cardio-cerebrovascular is a severe thread to the health of human beings. Since1980s, cardio-cerebrovascular has risen to the first among all the causes of death, while hypertension is the main danger to the cardio-cerebrovascular, such as stroke, coronary heart disease, etc., and it has become the most serious disease that severely threatens humans’health and lives, and that increases economic burden on the society. According to the survey on the epidemiology of Dalian Citizens, this paper tends to learn about the features of hypertension in Dalian city, analyze the main factors of hypertension related and its dangers, and provide scientific basis for making the policy related to the hypertension prevention and taking the specific measures.Method:By the method of stratified random sampling, two districts (county) were chosen among all the districts in Dalian City, among which two residents committees (village) were chosen randomly. Subjects should be those who have been living there for more than five years, aged over20. Consequently, in all5,340subjects have participated this survey and4,858effective questionnaires were collected. The effective ratio is92.89%. Through the EPidata3.1software, data were entered, which then were statistically analyzed using SPSS13.O. Statistical methods include t test,χ2test, analysis of variance, logistic regression, etc.Result:(1) the general epidemic characteristics of hypertensionThe survey shows that on average37.3%Dalian Citizens have got the disease of hypertension, and the number is35.7%in rural area while38.3%in suburb. As age rises, case rate also rises, especially to those over50years old. The case rate of men (40.5%)is higher than that of women (34.5%). This difference has statistical significance. The case rate of men aged20to50is also higher than that of women. This difference has statistical significance. After the age of50, the case rates of hypertension between women and men are almost the same, which has no statistical significance. (2) influence factors related to hypertensionSingle factor analysis shows that factors like the intake of milk product and fruit, bad habits (for example smoking and drinking), or physical activity and exercise, are closely related to the disease of hypertension, which is also the same to the survey result. The more intake of milk product and fruit, the lower case rate. The case rate of heavy smokers who have smoked for over20years and more than20cigarettes per day is the highest. With the increase of drinking time, the rate has a tendency to rise. The case rate of those who drink occasionally is the lowest, while the case rate is the highest to those who drink everyday. Also those citizens who seem to have no physical exercise have the highest case rate.But the survey shows that different intake of salt and vegetable has no influence on the case rate of hypertension, which is inconsistent with other materials. Maybe that is because patients with hypertension changed with eating behavior and turned to a healthier one, or because nowadays people have improved their health consciousness, increase their health knowledge and strengthen a good diet idea, and therefore the number of people who have high salt diet and low intake of vegetable decreases.Conclusion:1. The case rate of hypertension in Dalian City is37.3%, and with the increase of age, the rate becomes higher, especially to those over50years old.2. The influence factors of hypertension includes the eating habits of higher intake of milk product and fruit, drinking, smoking, but physical exercise, reasonable diet and good habits, and proper physical exercise will lower the case rate. Bad habits like long-term drinking and smoking will greatly increase the risk of hypertension. |
