Lifestyle Behaviors and Psychological Health in Adolescents with Overweight or Obesity: Cross-sectional Associations with Weight Underestimation

Abstract

Background: Encouraging adolescents with overweight/obesity to accurately perceive their weight in the belief that this will improve their lifestyle behaviors (physical activity [PA], sedentary behavior [SB], eating behavior [EB]) may be detrimental to their psychological health. This study aimed to investigate associations between weight underestimation and lifestyle behaviors along with psychological health in French adolescents with overweight or obesity.
Methods: Baseline data from adolescents who participated in a school-based trial were used. Lifestyle behaviors and psychological health (anxiety, depression, eating disorders, quality of life [QoL]) were self-reported. Weight underestimation was measured by matching objective and perceived weight status. Multilevel models were computed to investigate associations between weight underestimation and lifestyle behaviors and psychological health, by gender.
Results: Of the 1,245 adolescents included (15.3 ± 0.7 years), 15.8% underestimated their objective weight (boys: 24.2%; girls: 8.2%). Boys with underestimation had higher vigorous PA energy expenditure (β= 372.7 MET-min/week, 95%CI [25.1;720.4]), and lower daily sugar-sweetened beverages and foods consumption (β= -0.3 points, 95%CI [-0.7; -0.0]) than those with accurate perception. Girls with weight underestimation had lower eating disorder (β= -6.0 points, 95%CI [-9.6; -2.5]), anxiety (β= -7.8 points, 95%CI [-13.8; -1.9]), and higher QoL (β= 3.3 points, 95%CI [0.0; 6.5]) scores than girls with accurate perception.
Conclusions: Weight underestimation among adolescents with overweight or obesity was associated with healthier lifestyle behaviors in boys, and better psychological health (eating disorder, anxiety and QoL) in girls. Accurate perception of weight status may not be a relevant lever to improve lifestyle behaviors and psychological health.
