Obesity Stigma and Health Behavior: An Experimental Approach

University of California, Los Angeles·interventional·Posted Jun 2, 2022·Updated Jan 20, 2026

In Brief

A clinical study evaluating Weight stigma intervention for Obesity. Completed, enrolled 330 participants across 1 site.

Detailed Summary

The study will use a between-subjects design in a sample of individuals with BMI greater than or equal to 28 from the Los Angeles community (N=330). Participants will be randomly assigned to a weight stigma vs. control manipulation. Changes to the following health behaviors will be subsequently measured in their everyday lives: 3-day diet as captured by ecological momentary assessment (EMA) food diaries, objectively measured eating of obesogenic foods, objectively measured physical activity captured by 24-hour actigraphy, and sleep, captured objectively by overnight actigraphy and subjectively self-reported sleep measures. The investigators hypothesize that weight stigma causes decrements in health behaviors (e.g., sleep, eating, and physical activity) in everyday life.
