Associations between anti-bisexual minority stress and body esteem and emotional eating among bi+ individuals: The protective role of individual- and community-level factors.

Bisexual individuals experience prejudice specifically related to their bisexual identity, and these experiences may compound extant risk for disordered eating behaviors and body esteem concerns. However, little is known about how sexual minority stress related to bisexual orientation is associated with emotional eating and body esteem. The current study examined the associations between bisexual-specific minority stress and emotional eating and body esteem in a sample of bisexual plus (bi+) adults (including bisexual, pansexual, queer, and those with attractions to more than one gender regardless of identity), and tested the moderating effects of identity centrality, affirmation, and community connectedness as potential protective factors. This study leveraged data from an online survey of 498 adults (77.46% cisgender women; 79.7% White), ages 18 to 64 years (M = 28.5; SD = 9.59). Bisexual-specific minority stress was associated with more emotional eating (β = 0.15, p = .013) and lower body esteem (β = -0.16, p = .005), while controlling for sociodemographic characteristics, body mass index, and heterosexist minority stress. This finding remained the same when sensitivity analyses were conducted with participants who identified specifically as bisexual. Identity centrality and affirmation and community connectedness did not demonstrate moderating effects but they had main effects, such that they were positively associated with body esteem (β = 0.16, p = .001; β = 0.21, p < .001; β = 0.13, p = .004, respectively). Results suggest that anti-bisexual minority stress has a unique association with bi+ individuals' emotional eating and body esteem, and identified potential individual- and community-level protective factors for body esteem. These findings inform future research and interventions for this understudied population.
