Understanding how intimate relationships influence physical health has been an important topic of focus; however, research remains unclear on the mechanisms through which this influence occurs. The purpose of this study was to examine how relationship satisfaction relates to diet quality, through mental health (depression and anxiety) and diet self-efficacy. Using a dyadic mediation model with a sample of 234 heterosexual couples, researchers found that women\u27s higher relationship satisfaction was associated with better diet through lower depression and higher diet self-efficacy. Results revealed the same association between women\u27s relationship satisfaction and diet through lower anxiety. Interestingly, rather than mediation through mental health, the association between men\u27s relationship satisfaction and diet was mediated through their partners\u27 diet self-efficacy. This presentation will review the gendered pathways by which relationship satisfaction influences diet in heterosexual couples and discuss the important implications of these findings for tracing how intimate relationships affect overall well-being
