Background: Few longitudinal studies have investigated the role of weight-loss attempts or weight-related stress on body image during childhood. We examined whether weight-loss attempts and weight-related stress are associated with weight misperception and body dissatisfaction across childhood and adolescence. Methods: Data were drawn from the Quebec Adipose and Lifestyle InvesTigation in Youth (QUALITY) cohort of Canadian children with parental obesity (8-10 years: n = 630; 10-12 years: n = 564; 15-17 years: n = 377). We assessed weight-loss attempts and weight-related stress at baseline and first follow-up, and perceived and desired silhouettes at first and second follow-up with questionnaires. Weight misperception consisted of the difference in BMI z-score (zBMI) from the perceived silhouette and the measured zBMI. Body dissatisfaction consisted of the discordance between perceived and desired silhouettes. We estimated multivariable mixed-effects regression models adjusting for age, sex, pubertal stage, parental BMI and education, and sport-based teasing. Results: Weight loss attempts were associated with a higher weight misperception score (ever tried, beta [95% confidence intervals; CI]: 0.13 [0.01-0.24]) and with 2.13 times higher desire to be thinner (95% CI: 1.39-3.26) at the subsequent follow-up. Similarly, children stressed by their weight had a higher misperception score (beta [95% CI]: 0.15 [0.02-0.27]) and greater desire to be thinner at the next follow-up (odds ratio [95% CI]: 1.73 [0.999-3.00]). Conclusions: Weight-loss attempts and weight-related stress in children and adolescents are associated with weight misperception and body dissatisfaction, supporting empowerment and counseling focusing on healthy eating behaviors and a positive body image.
