Body image concerns may play a role in weight changing behaviour. The objective of this study was to assess body image in different weight groups. Participants reported satisfaction with (AE) and investment in (AO) appearance, and the discrepancy between current and ideal body size (BS). These scores were compared between weight groups based on body-mass index (BMI) using analysis of variance. One-sample t-tests and Cohen's d effect sizes examined the magnitude of differences within each weight group relative to neutral midpoints of the scales; cluster analysis identified body image profiles. A total of 27 896 women were included in this study. AE scores were highest for people with underweight and normal weight, AO scores were highest for the underweight group and lowest in class III obesity, and BS scores were largest in the obese groups (all p
