Effects of community - based comprehensive prevention on incidence and mortality of stroke
Abstract：Aim To explore the effective measures for lowering multiple risk factors for stroke and incidence and mortality of cerebrovascular disease in community population.Methods In Changsha city,2 geographically separated communities with registered population of approximately 50 000 each similar demographic characteristics were selected as either intervention or control communities in 1991.During April to May in 1992 before intervention,eight variables were measured in 812 and 831 subjects of random sampling individuals,35 to 74 years of age,from intervention and control community respectively.In intervention community,a program of treatment for hypertension,heart disease,and diabetes was instituted and health education was provided to the full intervention community. A follow - survey was conducted in 2000 in 804 and 826 subpopulation under the same condition as before it.Comparisons of intervention and control communities were pooled to yield a single summary.Results Systolic blood pressure,body mass index,body weight and high - density lipoprotein cholesterol significantly increased after intervention in the both communities(P< 0.05 or 0.01),and diastolic blood pressure,cholesterol and blood glucose also significantly increased in the control communities(P< 0.05);however, diastolic blood pressure tended to decrease,and triglycerides significantly decreased after intervention in the intervention area(P< 0.05).The prevalence of smoking 20 cigarettes or more daily in men was 44.6 % in 1992 and 42.4% in 2000 in the intervention community,meanwhile 45.2% in 1992 and 46.0 % in 2000 in the control community.Drinking rate tended to rise after intervention,however,no further attempt was possible to differentiate between 1991 and 2000 in each community.The crude and adjusted - incidence of stroke and crude mortality of stroke in 2000 in the intervention community were significantly lower than those in the control community(P< 0.05 or 0.01). Conclusion A community - based intervention for stroke reduction is feasible and effective in Changsha. Intervention measures,focused on health education and hypertension control,play an important and effective role in lowering incidence and mortality of stroke.
