Abstract:
Objective To evaluate the effect of blood pressure intervention program on stroke among high risk population aged 45-79 at the community level,in Beijing.Methods 7604 subjects were followed and given specific advice according to the situation of each individual,every month.Data regarding average blood pressure,number of hypertension control and the incidence of stroke among people in the community,were recorded and analyzed.Results Prior to the follow-up program,the hypertension prevalence was 64.1％ but both the systolic and diastolic blood pressure showed a reduction of 2.9 and 1.5 mm Hg,respectively after the intervention program was implemented,with t value as-20.987,-15.494,respectively,and P values were both 0.000.Decrease of BP at the first four follow-up experiences was more obvious.Decrease of systolic blood pressure appeared more in elderly (F value was 14.287,and P value was 0.000),in males (t value was-2.885,P value was 0.004),people living in suburban areas (t value was 5.314,P value was 0.000) and with poorer education (t value was-6.943,P value was 0.000).However,decrease of diastolic blood pressure was seen more in younger age population (F value was 22.864,P value was 0.000),in males (t value was-2.259,P value was 0.024) and those having received better education (t value was 2.428,P value was 0.015).Rate regarding hypertension control increased from 67.7％ to 87.9％ after the intervention program was implemented (x2 value was 324.595,P value was 0.000).Incidence of stroke was 2.7‰ and seen higher in suburban area (x2 value was 5.293,P value was 0.021).Conclusion Community intervention program on hypertension could both reduce the blood pressure and the incidence rate of stroke among high-risk population.The earlier the blood pressure intervention program started,the better the effect would be seen.Reduction of blood pressure in males seemed more obvious.In order to prevent or delay the occurrence of stroke,knowledge on hypertension prevention should be improved among populations at high risk.Individualized and comprehensive follow-up management programs should be strengthened among the community health care takers.
