Previous research demonstrates that lesbian and bisexual (LB) women report more binge eating behaviors compared to heterosexual women although the explanations for this disparity are not well understood. LB women also experience distal (e.g., discrimination) and proximal (e.g., expectations of rejection) minority stressors that are related to negative mental and physical health outcomes. The present study investigated the association between minority stressors and binge eating behaviors in LB women. A sample of 164 LB women completed an online survey that included measures of distal and proximal sexual minority stressors, emotional-focused coping, social isolation, negative affect, and binge eating. The resultant model partially supported both the psychological mediation framework and the affect regulation model. The principal finding was that among LB women, proximal stressors were associated with social isolation and emotion-focused coping, which in turn were associated with negative affect and ultimately binge eating. Overall, the study provides evidence that minority stress is associated with binge eating and may partially explain the disparity in binge eating between LB and heterosexual women.
