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.
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.
Of the 1245 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.
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.
鼓励超重/肥胖青少年准确认知自己的体重，认为这会改善他们的生活方式行为（身体活动（PA）、久坐行为（SB）、饮食行为（EB）），这可能对他们的心理健康有害。本研究旨在调查法国超重或肥胖青少年体重低估与生活方式行为以及心理健康之间的关联。
使用了参与一项基于学校试验的青少年的基线数据。生活方式行为和心理健康（焦虑、抑郁、饮食失调、生活质量（QoL））通过自我报告获得。通过匹配客观和感知的体重状况来测量体重低估。计算多水平模型以按性别调查体重低估与生活方式行为和心理健康之间的关联。
在纳入的1245名青少年（15.3±0.7岁）中，15.8%低估了他们的客观体重（男孩为24.2%；女孩为8.2%）。与体重认知准确的男孩相比，体重被低估的男孩有更高的剧烈身体活动能量消耗（β = 372.7代谢当量分钟/周，95%置信区间[25.1；720.4]），以及更低的每日含糖饮料和食物摄入量（β = -0.3分，95%置信区间[-0.7；-0.0]）。与体重认知准确的女孩相比，体重被低估的女孩饮食失调得分更低（β = -6.0分，95%置信区间[-9.6；-2.5]）、焦虑得分更低（β = -7.8分，95%置信区间[-13.8；-1.9]），生活质量得分更高（β = 3.3分，95%置信区间[0.0；6.5]）。
超重或肥胖青少年中的体重低估与男孩更健康的生活方式行为以及女孩更好的心理健康（饮食失调、焦虑和生活质量）相关。准确认知体重状况可能不是改善生活方式行为和心理健康的有效手段。
