Individual socioeconomic status (SES) has been found to be associated with cardiovascular diseases in developed countries, but the association between individual SES and metabolic syndrome (MetS) is still unclear in China. The objective of this study was to investigate the association between individual SES and MetS in China.
A cross-sectional study of 10054 community residents was performed from May to August 2007 using multistage stratified random sampling. SES was assessed in terms of education, personal monthly income, and household monthly income. The association between SES and MetS was determined by logistic regression models.
After the adjustments regarding age, marital status, smoking, drinking, physical activity, body mass index (BMI), and community type, odds ratios (ORs) for MetS of individuals with education level of 7~12 years and >12 years were 0.87 (95% confidence interval [CI]: 0.75 to 0.99) and 0.83 (95% CI: 0.62 to 0.91) respectively compared with those with education level of <7 years in women. Following the adjustments as above, ORs for MetS of individuals with household monthly income level of middle and higher were 0.94 (95% CI: 0.86 to 0.97), and 0.72 (95% CI: 0.65 to 0.88) respectively compared with those with lower household monthly income level in women. The association between SES and MetS was not significant in men.
Gender had an influence on the association between individual SES and MetS. Lower education and household monthly income level were associated with higher risk of MetS among community residents in women, while such association was not significant in men.
个体社会经济地位（SES）与发达国家的心血管疾病有关，但个体 SES 与代谢综合征（MetS）之间的关系在中国仍不清楚。本研究旨在探讨中国个体 SES 与 MetS 的关系。
采用多阶段分层随机抽样方法，于 2007 年 5 月至 8 月对 10054 名社区居民进行横断面研究。SES 评估包括教育程度、个人月收入和家庭月收入。采用 logistic 回归模型确定 SES 与 MetS 之间的关系。
在调整年龄、婚姻状况、吸烟、饮酒、体力活动、体重指数（BMI）和社区类型后，与教育程度<7 年的女性相比，教育程度为 7~12 年和>12 年的女性患 MetS 的比值比（OR）分别为 0.87（95%置信区间[CI]：0.75 至 0.99）和 0.83（95% CI：0.62 至 0.91）。在进行上述调整后，与家庭月收入水平较低的女性相比，家庭月收入水平中等及以上的女性患 MetS 的 OR 分别为 0.94（95% CI：0.86 至 0.97）和 0.72（95% CI：0.65 至 0.88）。SES 与 MetS 之间的关系在男性中不显著。
性别对个体 SES 与 MetS 之间的关系有影响。较低的教育程度和家庭月收入水平与女性社区居民患 MetS 的风险增加相关，而在男性中则不显著。
