目的探讨有“临界”水平心血管病危险因素的居民疾病发展变化情况。方法对某社区共446人的心血管病危险因素的变化情况进行随访观察3年。结果 “临界”高血压(120～139/80～89 mm Hg)、高血糖(6.1～6.9 mmol/L)、高胆固醇血症(5.18～6.19 mmol/L)者分别占居民的45.3%、16.4%、16.1%。3年间高血压、糖尿病和高胆固醇血症的发生率分别为28.7%、9.6%、6.9%,其相对危险性分别是血压、血糖、胆固醇处于正常水平者的3.2倍、11.2倍和4.3倍(P均<0.05)。结论心血管病危险因素血压、血糖、胆固醇处于“临界”水平的居民3年间高血压、糖尿病、高脂血症的发病率较血压、血糖、胆固醇处于正常水平者显著升高;其中“临界”高血压居民的比例最高,其发展为高血压的发生率亦较高。
Objective To explore the changes of residents’ diseases with risk factors of “critical” level of cardiovascular disease. Methods A total of 446 people in a community of cardiovascular disease risk factors were followed up for 3 years. Results “Critical” hypertension (120 ~ 139/80 ~ 89 mm Hg), hyperglycemia (6.1 ~ 6.9 mmol / L) and hypercholesterolemia (5.18 ~ 6.19 mmol / L) accounted for 45.3% , 16.4%, 16.1%. The incidences of hypertension, diabetes and hypercholesterolemia in three years were 28.7%, 9.6% and 6.9%, respectively. The relative risk was 3.2 times, 11.2 times and 4.3 times higher than those with normal blood pressure, blood sugar and cholesterol P <0.05). Conclusions The incidence of hypertension, diabetes mellitus and hyperlipidemia among residents with blood pressure, blood sugar and cholesterol at the “critical” level for 3 years is significantly higher than that of the normal subjects with blood pressure, blood sugar and cholesterol. Among them, “Critical” high proportion of residents with hypertension, its development is also a high incidence of hypertension.
