目的探讨代谢综合征(MS)患病率的性别差异,分析不同性别代谢综合征各组分的聚集特征。方法有效样本20502名,男性6997人,女性13505人,分别对其代谢综合征的组分[血压、体质指数(BMI)、腰围(WC)、血清胆固醇(TC)、三酰甘油(TG)、高密度脂蛋白胆固醇(HDL-C)、空腹血糖(FPG)]进行因子分析。结果代谢综合征患者3434人,粗患病率为16.75%,其中男性为11.52%,女性为19.46%,女性粗患病率显著高于男性(P<0.001);标化率为10.74%,其中男性为10.35%,女性为11.16%。男性WC、收缩压(SBP)、舒张压(DBP)高于女性,女性BMI、TC、HDL-C、FPG高于男性,差异均有统计学意义(P<0.05),男女性之间TG差异无统计学意义。男、女因子分析分别都提取了4个主要因子,因子方差累计贡献率分别为80.898%,78.347%。男女代谢综合征组分的聚集性基本相同但也存在差异,肥胖因子处于核心地位,血压因子为重要且独立的因子,其次是血脂紊乱因子、血糖因子。结论代谢综合征是多因素综合作用的结果,该调查研究显示肥胖因子、血压因子作用较强,男女代谢综合征的因子构成存在差异。
Objective To investigate the gender differences in the prevalence of metabolic syndrome (MS) and to analyze the characteristics of aggregation of various components of metabolic syndrome in different sexes. Methods A total of 20,502 validated samples were collected from 6997 males and 13,505 females. Their blood pressure, BMI, WC, TC, TG, HDL-C, FPG] were analyzed by factor analysis. Results There were 3434 patients with metabolic syndrome, the crude prevalence rate was 16.75%, of which 11.52% for males and 19.46% for females, crude prevalence in females was significantly higher than that in males (P <0.001); the standardization rate was 10.74% 10.35% for males and 11.16% for females. The WC, systolic blood pressure (SBP) and diastolic blood pressure (DBP) of males were higher than those of females. The levels of BMI, TC, HDL-C and FPG were higher in males than in females (P <0.05) No statistical significance. Male and female factor analysis were extracted four main factors, respectively, the cumulative variance of the factors were 80.898%, 78.347%. Metabolic syndrome of men and women gathered in basically the same but also differences, the obesity at the core, the blood pressure is an important and independent factor, followed by dyslipidemia, blood glucose. Conclusion Metabolic syndrome is the result of multifactorial combination. The investigation shows that the factors of obesity and blood pressure are stronger, and the factors of the metabolic syndrome of men and women are different.
