摘要
本研究报告分析了在中国七个大城市进行的脑血管病危险因素干预实验对队列人群血压的影响.37661名35岁以上市区居民分为干预组和对照组.研究结果显示;干预组收缩压和舒张压均值复查比基线时有所下降.而对照组正好相反,都有所上升.干预组确诊高血压的比例从基线时的18.4%降至复查时的15.5%,而对照组则从17 5%上升至17.7%.在基线血压正常且以往无高血压史者中,干预组男性与女性确诊高血压的发病率分别为6.5%和4.9%,都低于对照组的7.6%和8.0%.脑卒中的发病率随血压(收缩压或舒张压)的增高而上升,几乎在各个血压等级中,干预组脑卒中发病率都低于对照组.上述干预组和对照组之间的差别都具有统计学显著意义.
A two year experiment in intervention of risk factors forcerebrovascular disease was carried out in seven large cities inChina, and the effect of the intervention on blood pressure wasstudied in a cohort population with 3766] individuals over 35?years of age, divided into the study group and control group.The findings of the experiment showed that the levels of systolic and diastolic blood pressure in the study group decreased at terminal examination as compared to that at baseline survey, in contrast to that, the levels in the control group increased. The prevalence rate of definite hypertension in the study group also decreased from 18.4% at baseline survey to 15. 5% at terminal examination while in the control group it slightly increased from 17.5% to 17.7%. In the study group, incidence rates of definite hypertension among normotensives at baseline survey were 6. 5% for males and 4. 9% for females. Both were lower than that in the control group (for males 7.6% , for females 8. 0%).The incidence rate of stroke increased with increasing levels of systolic or diastolic blood pressure. And the incidence rate at any level of blood pressure was lower in the study group than that in the control group- AH the differences in the incidence rates between the study group and control group were statistically significant.
