To evaluate the association of body image with physical activity level, body composition, and sedentary behavior (SB) of female adolescents.
Exploratory cross-sectional study conducted with 120 female adolescents aged between 14-19 years, from the city of Viçosa, Minas Gerais, Southeast Brazil. Body image was evaluated with a Body Silhouette Scale (BSS) and a Body Shape Questionnaire (BSQ). Weight, height, and waist circumference values were analyzed, as well as the waist-to-height ratio and body fat percentage. The physical activity level (PAL) was assessed by 24-hour Physical Activity Recall and SB by screen time, that is, time spent in front of a TV, playing video game, on the computer and using tablets, and, separately, the cell phone time.
Mean age was 16.5±1.5 years, and most adolescents were eutrophic (77.6%), sedentary/low PAL (84.2%), with high screen time (85.2%) and cell phone time (58.7%). Body dissatisfaction was stated in 40.6% of BSQ and 45.8% of BSS evaluations. Body distortion was identified in 52.9% of participants. All body composition measures, along with cell phone time and PAL, were associated with body dissatisfaction, the more active adolescents presenting higher levels of dissatisfaction.
This study concluded that female adolescents with higher cell phone time also present higher body dissatisfaction, as well as the most physically active ones. All body composition measurements were associated with body dissatisfaction, mainly body mass index, waist circumference, and waist-to-height ratio.
评估女性青少年的身体意象与身体活动水平、身体成分及久坐行为（SB）之间的关联。
对来自巴西东南部米纳斯吉拉斯州维索萨市的120名14 - 19岁女性青少年进行探索性横断面研究。采用身体轮廓量表（BSS）和身体形状问卷（BSQ）评估身体意象。分析体重、身高、腰围值，以及腰高比和体脂百分比。通过24小时身体活动回忆评估身体活动水平（PAL），通过屏幕使用时间评估久坐行为，即花在电视前、玩电子游戏、使用电脑和平板电脑上的时间，以及单独的手机使用时间。
平均年龄为16.5±1.5岁，大多数青少年营养状况良好（77.6%），久坐/身体活动水平低（84.2%），屏幕使用时间长（85.2%），手机使用时间长（58.7%）。在40.6%的BSQ评估和45.8%的BSS评估中表示对身体不满意。52.9%的参与者存在身体变形。所有身体成分指标，连同手机使用时间和身体活动水平，均与身体不满意相关，身体活动越活跃的青少年不满意程度越高。
本研究得出结论，手机使用时间长的女性青少年以及身体活动最活跃的女性青少年身体不满意程度也更高。所有身体成分测量指标均与身体不满意相关，主要是体重指数、腰围和腰高比。
