慢性病危险因素聚集是指一个人具有某一个可能导致慢性病发生的危险因素的同时,还具有另外一个或几个危险因素的现象。这种危险因素在个体身上聚集时产生的致病作用,而不是单个因素的简单叠加,是存在一种交互和协同作用,使发生慢性病的危险成倍增长。以2011年的监测数据为例,高血压、糖尿病、血脂异常、吸烟和超重肥胖是心脑血管事件发生的危险因素,在北京市18~79岁常住居民中,同时具备至少3个危险因素的居民达33.5%,那么,这类人群患脑卒中、冠心病的风险就会远高于只有1种或2种危险 Chronic disease risk factors Aggregation refers to a person with one of the risk factors that may lead to chronic diseases, but also have another one or several risk factors. The risk-causing effects of aggregation of individuals on individuals, rather than the simple overlay of individual factors, present an interaction and synergy that multiplies the risk of developing chronic conditions. Take the monitoring data of 2011 as an example. Hypertension, diabetes, dyslipidemia, smoking and overweight and obesity are risk factors of cardiovascular and cerebrovascular events. Among the 18 to 79-year-old residents in Beijing, at least 3 risk factors 33.5% of residents, then, such people suffering from stroke, the risk of coronary heart disease will be much higher than only one or two kinds of danger
