Subjective social status (SSS), or perceived social status, may explain, in part, the relationship between socioeconomic status (SES) and obesity. The objective of this study was to test whether SSS mediates the relationship between two indicators of SES (income and education) and body mass index (BMI).
A cross-sectional, structural equation path analysis was applied to the Coronary Artery Risk Development in Young Adults (CARDIA) study (n = 2,624). The analysis tested whether SSS (MacArthur scale), education, and income were associated with BMI at the year 20 examination (adjusting for sex, age, and race), and it was hypothesized that the associations of education and income with BMI would be at least partly mediated by SSS.
SSS had a significant direct effect on BMI (-0.21, P = 0.018). Education had a significant direct relationship with SSS (0.11, P < 0.001) and a small but significant indirect relationship with BMI through SSS (-0.02, P = 0.022). Although income did not have a significant direct relationship with BMI, it did have a significant indirect relationship through SSS (b = -0.05, P = 0.019).
Results are consistent with the hypothesized model in which SSS partially mediates the relationship between SES indicators and BMI.
主观社会地位（SSS），或感知社会地位，可能在一定程度上解释了社会经济地位（SES）与肥胖之间的关系。本研究的目的是检验 SSS 是否在 SES 的两个指标（收入和教育）与体重指数（BMI）之间的关系中起中介作用。
采用横断面结构方程路径分析方法对冠状动脉风险发展在年轻人（CARDIA）研究（n=2624）进行分析。该分析检验了 SSS（麦克阿瑟量表）、教育和收入与 20 次检查时的 BMI 之间的相关性（调整性别、年龄和种族），并假设教育和收入与 BMI 的相关性至少部分通过 SSS 来介导。
SSS 对 BMI 有显著的直接影响（-0.21，P=0.018）。教育与 SSS 有显著的直接关系（0.11，P<0.001），并且通过 SSS 与 BMI 有微弱但显著的间接关系（-0.02，P=0.022）。尽管收入与 BMI 没有显著的直接关系，但通过 SSS 与 BMI 有显著的间接关系（b=-0.05，P=0.019）。
结果与假设模型一致，即 SSS 部分中介 SES 指标与 BMI 之间的关系。
