A meta-analysis of empirical studies of weight-based bias in the workplace

For nearly 30 years researchers have investigated how bodyweight affects evaluative workplace outcomes, such as hiring decisions and performance appraisals. Despite this, no meta-analytic review has been undertaken to quantify the negative impact that bodyweight has on such outcomes. The results of this meta-analytic study suggest that in relation to non-overweight individuals in the workplace, overweight individuals may be disadvantaged across evaluative workplace outcomes (d = −.52). Further, differences in magnitude of the effects of weight-based bias were found for hiring (d = −.70) and performance (d = −.23) outcomes.
