This study’s purpose was to examine 9‐year trends in misperceptions of body size and dieting for weight loss among adolescents from 24 countries, and explore the influence of country‐level overweight prevalence. Body size perception and dieting for weight loss were assessed in the Health Behaviour in School‐aged Children survey conducted in 24 countries cross‐sectionally at 3 time points (2001/02, 2005/06, 2009/10). Logistic regression models examined change over time in over‐ and under‐estimation of body size and dieting for weight loss. Compared to Time 1, overweight adolescents had greater odds of body size underestimation at Time 3 (OR=1.68 for girls, OR=1.10 for boys), while non‐overweight adolescents had lower odds of body size overestimation at Time 3 (OR=0.87 for girls, OR=0.89 for boys). Controlling for country‐level overweight prevalence attenuated these relationships. Compared to Time 1, overweight and non‐overweight boys were 10% more likely to diet at Time 3, while overweight and non‐overweight girls were 19% and 16%, respectively, less likely to diet at Time 3. Controlling for country‐level overweight prevalence did not impact trends in dieting for weight loss. Findings suggest body size perceptions among adolescents may have changed over time concurrent with shifts in country‐level body weight.
