[The effect of medical treatment on hypertension community control--a follow-up study of more than one thousand hypertensives in East City Proper, Beijing].

Hypertension exerts a great threat on human health. Although most of countries promote the management of hypertension in communities, the role of treatment of hypertension is still controversial, it directly influences the strategy of hypertension community control. This study was based on the survey of essential and borderline hypertension in Gu-lou District of East City Proper, Beijing in 1981, and the management of 1339 hypertensives in the follow-up from 1982 to 1985, and the mortality registration in the district by Disease Surveillance System. By observing the prognosis within one year among different treatment groups (nonusers, less than 9 months and more than 9 months within one year), 1289 patients were followed up for a total of 4283 person-years. Crude analyses, stratified and logistic analyses with multi-variables adjustment of age, sex, blood pressure, with or without end-organ damage, etc. could not find that treatments had obvious effects on the reduction of incidence and mortality of stroke, mortality of CVD and all-cause in hypertensives except severe cases. The stratified analyses dy smoking also showed that smoking had a disadvantageous effects for treated hypertensives. Based on our results, we suggest that health education should be a major part of hypertension management program in community; treatments of hypertension should consider the flexible situation of patients and may not be a priority in hypertension community control program.
