To investigate the association of metabolic syndrome (MetS) and its components with socioeconomic status (SES) among general and gender-specific adult population in Nanjing municipality, China.
Cross-sectional study.
13287 participants completed the survey. A participant: (1) must be a local registered resident, (2) aged 18+ years, (3) had no literal or physical/mental problems and (4) was not pregnant.
MetS was the outcome variable, which was defined based on the diagnostic criteria released by the Chinese Diabetes Society. SES was the main explanatory measure, which was indicated with educational attainment and family average income (FAI), separately.
The prevalence of MetS was 19.7% (95% CI=19.0% to 20.4%) among overall participants, and 24.6% (95% CI=23.5% to 25.6%) and 15.5% (95% CI=14.7% to 16.4%) for men and women, respectively. After controlling for potential confounders, participants with either college level (OR=0.51, 95% CI=0.43 to 0.60) or high school level education (OR=0.78, 95% CI=0.70 to 0.90) were at lower odds to experience MetS compared with those with primary education, while only those within upper FAI tertile were at significantly lower risk of MetS relative to their counterparts within lower FAI category (OR=0.85, 95% CI=0.76 to 0.97) among overall participants. Meanwhile, with respect to the five components of MetS, higher educational level predicted lower waist circumference (WC), triglycerides, systolic blood pressure (SBP) and diastolic blood pressure (DBP) and fasting glucose concentration among all participants. And higher FAI was associated with lower WC and SBP and DBP in women, and with lower SBP and DBP in men.
Education and FAI each were inversely associated with MetS and its components at the present stage of economic development in Nanjing Municipality of China. It has important public health implications that the tailored prevention strategies for MetS should be put into consideration of the intervention of MetS components and subgroups of people with different SES.
在中国南京市的一般人群和特定性别人群中，调查代谢综合征（MetS）及其各组成部分与社会经济地位（SES）之间的关联。
横断面研究。
共有 13287 名参与者完成了调查。参与者必须符合以下条件：（1）当地注册居民，（2）年龄在 18 岁以上，（3）无语言或身体/精神问题，（4）未怀孕。
代谢综合征是因变量，根据中国糖尿病学会发布的诊断标准定义。社会经济地位是主要的解释性指标，分别用教育程度和家庭平均收入（FAI）表示。
总体参与者中 MetS 的患病率为 19.7%（95%CI=19.0%至 20.4%），男性和女性分别为 24.6%（95%CI=23.5%至 25.6%）和 15.5%（95%CI=14.7%至 16.4%）。在控制了潜在的混杂因素后，与受教育程度为小学的参与者相比，具有大学水平（OR=0.51，95%CI=0.43 至 0.60）或高中学历（OR=0.78，95%CI=0.70 至 0.90）的参与者患 MetS 的几率较低，而仅在较高的 FAI 三分位组的参与者中，MetS 的风险显著低于较低的 FAI 组（OR=0.85，95%CI=0.76 至 0.97）。同时，就 MetS 的五个组成部分而言，较高的教育程度预示着所有参与者的腰围（WC）、甘油三酯、收缩压（SBP）和舒张压（DBP）以及空腹血糖浓度较低。较高的 FAI 与女性的 WC 和 SBP 以及 DBP 较低以及男性的 SBP 和 DBP 较低有关。
在南京市现阶段的经济发展水平下，教育和 FAI 均与 MetS 及其各组成部分呈负相关。这具有重要的公共卫生意义，即针对 MetS 的定制预防策略应考虑干预 MetS 及其各组成部分以及不同 SES 亚组的人群。
