RESUMEN
OBJECTIVES: The focus on physical appearance among gay men has potential implications for anti-fat attitudes, including those directed toward romantic partners. Partners often influence each other's behaviors including those linked to weight, but most research has examined the consequences of these influence strategies versus their antecedents. To address this research gap, we examined how men's own and their partners' anti-fat attitudes were related to both health-promoting (control) and health-compromising (undermining) types of diet-related influence and whether these associations differed by weight status. METHODS AND RESULTS: Analyzing data from a cross-sectional online survey of 450 U.S. adult gay married men (225 couples), Actor-Partner Interdependence Models revealed that individuals' own anti-fat attitudes (all types) were positively associated with more frequent receipt of spousal control and undermining. Additionally, partner's fears about gaining weight were positively associated with more frequent receipt of spousal control and dislike of higher weight people and fear of gaining weight (among those of higher weight status) were positively associated with more frequent receipt of spousal undermining. CONCLUSION: Our findings add to the literature on diet-related interactions among gay married men, highlight the value of examining these processes dyadically, and suggest the importance of including both members of couples in health promotion and intervention efforts.
