Body dissatisfaction is distressing and a risk factor for adverse consequences including eating disorders. However, data pertaining to the prevalence of body dissatisfaction in adolescence, a key period for its emergence, are lacking. This is a substantial barrier to tailored assessment and early intervention. This study addresses this gap and provides the prevalence of body dissatisfaction and associations with depressive symptoms and body change strategies. Adolescent boys (n = 367; Mage = 12.8, SD = 0.7) and girls (n = 368; Mage = 12.7, SD = 0.7) completed measures of body dissatisfaction and depressive symptoms with established cut-off levels. They also completed measures of dietary restraint and strategies to increase muscle size. Of boys and girls, 37.9% and 20.7%, respectively experienced moderate, and 6.8% and 19.6% experienced clinically significant body dissatisfaction, with higher rates among girls than boys and among adolescents aged 13 and 14 than aged 12. More than one-quarter of boys (26.70%) and one-third of girls (33.15%) reported subthreshold depressive symptoms or possible, probable or major depressive episodes. Girls revealed a higher prevalence of possible-, probable-, or major depressive episode than boys. Relative to those with no or low body dissatisfaction, adolescents with clinically significant body dissatisfaction were 24 times more likely to also report possible-, probable-, or major depressive episodes. Among boys and girls, clinically significant body dissatisfaction was associated with higher levels of dietary restraint and engagement in strategies to increase muscle size. Greater attention to identification and early intervention for body dissatisfaction is needed, especially for girls.

对身体的不满是令人痛苦的，也是导致饮食失调等不良后果的危险因素。然而，缺乏关于青春期身体不满流行率的数据，青春期是其出现的关键时期。这是量身定制的评估和早期干预的重大障碍。这项研究解决了这一差距，并提供了身体不满的普遍程度以及与抑郁症状和身体变化策略的关联。青春期男孩（n  = 367；Mage = 12.8，SD = 0.7）和女孩（n = 368; Mage = 12.7, SD = 0.7) 完成了身体不满和抑郁症状的测量，并具有既定的截止水平。他们还完成了饮食限制措施和增加肌肉大小的策略。在男孩和女孩中，分别有 37.9% 和 20.7% 的人经历过中度，6.8% 和 19.6% 的人经历过具有临床意义的身体不满，女孩的比例高于男孩，13 岁和 14 岁青少年的比例高于 12 岁。超过四分之一的男孩 (26.70%) 和三分之一的女孩 (33.15%) 报告了阈下抑郁症状或可能、很可能或严重的抑郁发作。与男孩相比，女孩可能、很可能或重度抑郁发作的患病率更高。相对于没有或身材不满度低的人，具有临床显着身体不满的青少年也报告可能、很可能或重度抑郁发作的可能性高出 24 倍。在男孩和女孩中，临床上显着的身体不满与更高水平的饮食限制和参与增加肌肉大小的策略有关。需要更加重视对身体不满的识别和早期干预，尤其是对女孩而言。
