Lifetime and Daily Weight Stigma among Higher Weight Sexual Minority Women: Links to Daily Weight-based Concerns, Avoidance, and Negative Affect.

Background: Weight stigma is associated with a range of adverse health outcomes (e.g., disordered eating). Women, sexual minorities, and higher-weight individuals are at increased risk of experiencing weight stigma, but little is known about its influence on emotions, cognitions, and behaviors in real-world contexts, particularly among multiply marginalized individuals such as higher-weight sexual minority women (SMW). The current study examined how lifetime and daily weight stigma experiences relate to momentary weight/shape concerns, size-based avoidance, and negative affect in this population.

Methods: Fifty-five higher-weight (BMI > 25 kg/m2) SMW completed a baseline survey and a five-day Ecological Momentary Assessment protocol (five prompts per day) assessing weight stigma events, weight/shape concerns, size-based avoidance, and negative affect.

Results: Greater frequency of lifetime weight stigma experiences was significantly associated with greater odds of engaging in size-based avoidance at least once during the 5-day period. Reporting momentary weight stigma events at any given prompt was significantly associated with greater odds of reporting momentary weight/shape concerns, but not negative affect, at the same prompt. Greater frequency of lifetime weight stigma experiences was also marginally associated with greater odds of reporting momentary weight/shape concerns at any given prompt.

Conclusions: Both lifetime and momentary experiences of weight stigma are linked to negative consequences (e.g., weight/shape concerns, size-based avoidance) among higher-weight SMW. Although structural interventions are needed to reduce weight stigma at its source, individual interventions can help higher-weight SMW to cope with weight stigma in ways that may reduce its negative consequences.
