This cross-sectional study contributes to the literature on whether body dissatisfaction is a barrier/facilitator to engaging in physical activity and to investigate the impact of mass-media messages via computer-time on body dissatisfaction. High-school students ( N = 1501) reported their physical activity, computer-time (homework/leisure) and body dissatisfaction. Researchers measured students' weight and height. Analyses revealed that body dissatisfaction was negatively associated with physical activity on both genders, whereas computer-time was associated only with girls' body dissatisfaction. Specifically, as computer-homework increased, body dissatisfaction decreased; as computer-leisure increased, body dissatisfaction increased. Weight-related interventions should improve body image and physical activity simultaneously, while critical consumption of mass-media interventions should include a computer component.
本横断面研究有助于了解身体不满是否是参与体育活动的障碍/促进因素，并探讨通过电脑时间传播的大众媒体信息对身体不满的影响。研究报告了 1501 名高中生的体育活动、电脑时间（家庭作业/休闲）和身体不满情况。研究人员测量了学生的体重和身高。分析结果显示，身体不满与两性的体育活动均呈负相关，而电脑时间仅与女孩的身体不满相关。具体而言，随着电脑作业时间的增加，身体不满减少；随着电脑休闲时间的增加，身体不满增加。与体重相关的干预措施应同时改善身体形象和体育活动，而对大众媒体干预措施的批判性消费应包括电脑部分。
