The interaction between BMI, weight criticism, weight bias, and psychological and relational outcomes within marriage

Purpose To examine (1) whether a wife's BMI interacts with either her husband's weight stigma or (2) her perceived weight criticisms from her husband predict husbands' and wives' psychological and relational outcomes. Methods The study sample consisted of 209 currently married men and women in a heterosexual relationship. Participants were drawn from an online survey platform (Qualtrics, Inc. Provo, UT) designed to approximate the US population on age, race, and region of the country. Online measures assessed husbands' weight stigma, wives' perceived weight criticisms from husband, and husbands' and wives': (1) relationship satisfaction, (2) sexual intimacy, (3) self-esteem, (4) depressive symptoms, and (5) perceptions of a desirable or ideal mate. Results Wives' BMI interacted with husbands' weight stigma to predict (1) mate value for husbands and wives and (2) marital satisfaction for husbands. The same pattern was noted with interaction of wives' BMI and perceptions of husbands' weight related criticisms. The interaction reflected that higher wife BMI and higher husband weight stigma or wife perceived weight-related criticism predicted lower marital satisfaction, greater depression, and lower perceptions of a desirable or an ideal mate. Lower BMI was not associated with outcomes regardless of the husbands' weight stigma or wives' perceived weight-related criticisms. Conclusion To understand the impact of weight stigma and weight related criticisms on perceptions of a desirable or ideal mate and marital outcomes, it is important to examine the interaction with partner's BMI.

Automated summary

The study found that a wife's BMI interacts with her husband's weight stigma or perceived weight criticisms to predict mate value for husbands and wives, as well as marital satisfaction for husbands. Higher BMI in wives in combination with higher weight stigma or weight-related criticisms in husbands led to lower marital satisfaction, more severe depression, and lower perceptions of an ideal mate. Lower BMI was not associated with these outcomes regardless of husbands' weight stigma or wives' perceived weight-related criticisms.
