Multiple logistic regression analysis was used to identify the factors associated with weight misperception. Variables included in the final regression analyses: for men, intention to eat healthily, leisure-time physical activity, self-rated health and survey year); for women, leisure-time physical activity, self-rated health and survey year.
*‘Misperceivers’ refers to overweight individuals who did not perceive themselves as overweight, while ‘correct perceivers’ refers to overweight individuals who did perceive themselves as overweight.
†Proportion of weight misperceivers among overweight Danes.
‡No association was found in women.
