To investigate the association between body image disorders and the lifestyle and body composition of female adolescents.
Cross-sectional study.
The Body Shape Questionnaire (BSQ) and Silhouette Scale and Sociocultural Attitudes Towards Appearance Questionnaire-3 were used to evaluate the participants' body image. Body composition was evaluated by a Dual-Energy X-ray Absorptiometry equipment, and lifestyles were identified by latent class analysis (LCA) using the poLCA package for R.
Female adolescents aged 14-19 years old, in the city of Viçosa-MG, Brazil.
In total, 405 girls participated in the study. Almost half of the participants were dissatisfied with their current physical appearance (51·4 %), presented body perception distortions (52·9 %). 47·3 % of the adolescents were dissatisfied with their body according to the BSQ, and another 8 % severely so. Subjects with an 'Inactive and Sedentary' latent lifestyle were 1·71 times as likely to feel dissatisfied as those with active and sedentary or inactive and non-sedentary lifestyles (95 % CI 1·08, 2·90, P = 0·047). Body image disorders showed an association with decreased amounts of moderate and vigorous physical activity, high screen time, increased alcohol consumption and excess body fat.
Particular patterns of lifestyle and body composition seem to be associated in female adolescents with dissatisfaction with, distortion of and excessive concern about appearance. Specifically, physical inactivity, sedentary behaviour, alcohol consumption and high body fat percentage may be strongly linked to body image disorders.
研究女性青少年的身体意象障碍与生活方式和身体成分的关系。
横断面研究。
使用身体意象问卷（BSQ）和剪影量表以及社会文化态度对外观问卷-3 评估参与者的身体意象。通过双能 X 射线吸收仪评估身体成分，通过 R 中的 poLCA 包进行潜在类别分析（LCA）来确定生活方式。
巴西维索萨市 14-19 岁的女性青少年。
共有 405 名女孩参加了这项研究。几乎一半的参与者对自己目前的外貌不满意（51.4%），表现出身体感知扭曲（52.9%）。47.3%的青少年根据 BSQ 对自己的身体不满意，另有 8%的人非常不满意。具有“不活跃和久坐”潜在生活方式的受试者感到不满的可能性是活跃和久坐或不活跃和非久坐生活方式受试者的 1.71 倍（95%CI 1.08, 2.90，P = 0.047）。身体意象障碍与中等强度和剧烈身体活动减少、屏幕时间增加、饮酒增加和体脂过多有关。
生活方式和身体成分的特定模式似乎与女性青少年对外观的不满、扭曲和过度关注有关。具体而言，身体不活动、久坐行为、饮酒和高体脂百分比可能与身体意象障碍密切相关。
