Pooled result
As reported in the abstract
- Studies using weight status measures: actual and self-perceived higher weight were risk factors for anticipated rejection, dietary control challenges, increased physiological stress and greater functional disability following stigmatisation
- Studies measuring connection with the higher-weight group: stronger identification had protective effects on self-esteem and distress, but only for specific individuals (e.g., those with low internalised weight bias)
