The tendency for selected cardiovascular disease (CVD) risk factors to occur in clusters has led to the description of metabolic syndrome (MetS). The relative impact of the individual risk factor on the overall relative risk (RR) for cardiovascular death from metabolic syndrome is not well established and may differ across the different racial/ethnic groups. Using data from the National Health and Nutrition Examination Survey (NHANES II) mortality follow-up (NH2MS), we determined the prevalence and RR of cardiovascular death for individual components in the overall population and across racial and ethnic groups. The prevalence of MetS components varied significantly across gender and racial/ethnic groupings. The RR for CVD also varies for the number and different components of MetS. The adjusted RR for cardiovascular death was highest with diabetes (3.23; 95% CI: 2.70-3.88), elevated blood pressure (2.28; 95% CI: 1.94-2.67) and high triglycerides (1.63; 95% CI: 1.34-2.00). Although the RR for cardiovascular death differs significantly for some of the different components, the overall findings were similar across racial/ethnic groups. The two components that confer the highest risks for death are more prevalent in African Americans. We concluded that the RR of cardiovascular death associated with the diagnosis of MetS varies depending on the number and components used to establish the diagnosis of MetS and the racial/ethnic characteristic of the participants.
特定心血管疾病(CVD)危险因素成簇出现的倾向促使了代谢综合征(MetS)这一概念的形成。个体危险因素对代谢综合征所致心血管死亡总体相对风险(RR)的影响尚未明确,且可能因不同种族/族裔群体而异。利用美国国家健康与营养检查调查(NHANES II)死亡率随访(NH2MS)的数据,我们确定了总体人群以及不同种族和族裔群体中各单项指标的心血管死亡患病率及RR。代谢综合征各组分的患病率在性别和种族/族裔分组中差异显著。心血管疾病的RR也因代谢综合征的数量和不同组分而有所不同。经调整后的心血管死亡RR在糖尿病患者中最高(3.23;95%可信区间:2.70 - 3.88),其次是血压升高(2.28;95%可信区间:1.94 - 2.67)和高甘油三酯血症(1.63;95%可信区间:1.34 - 2.00)。尽管某些不同组分的心血管死亡RR差异显著,但总体研究结果在不同种族/族裔群体中相似。导致死亡风险最高的两个组分在非裔美国人中更为普遍。我们得出结论,与代谢综合征诊断相关的心血管死亡RR因用于确立代谢综合征诊断的指标数量和组分以及参与者的种族/族裔特征而异。
