Key result
Subjective social status had a significant direct effect on body mass index (-0.21, P=0.018) and partially mediated the relationship between socioeconomic status indicators and BMI.
Why the study?
Does subjective social status mediate the relationship between socioeconomic status (income and education) and body mass index in young adults?

Effect estimate: direct effect -0.21
p-value: p=0.018
Subjective social status partially mediates the relationship between socioeconomic status indicators and body mass index, suggesting perceived status plays a role in obesity risk.
SSS may mediate SES-BMI links in young adults; hypothesis-generating, with no causal or practice implications yet.
OBJECTIVE: 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). METHODS: 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. RESULTS: 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). CONCLUSIONS: Results are consistent with the hypothesized model in which SSS partially mediates the relationship between SES indicators and BMI.

Dhurandhar et al. (2017) conducted a cross-sectional in Obesity (n=2,624). Subjective social status (SSS) was evaluated on Body mass index (BMI) (direct effect -0.21, p=0.018). Subjective social status had a significant direct effect on body mass index (-0.21, P=0.018) and partially mediated the relationship between socioeconomic status indicators and BMI.
