With an increasing incidence of obesity, the relationship between obesity and body image has become a hot research topic worldwide. From high school to university, young people experience changes in their social environment. University students have a high incidence of eating disorders and insufficient physical activity. The purpose of this study was to explore the relationship between body dissatisfaction, insufficient physical activity, and disordered eating behaviors among university students in southern China.
In total, 1296 university students aged 18-23 years were recruited for this study. The participants completed anthropometric measurements, the Physical Activity Rating scale-3 (PARS-3), and the Chinese-Dutch Eating Behavior Questionnaire (C-DEBQ). The ideal weight and silhouette were reported by university students using a questionnaire.
Compared with men, young women had a higher level of body dissatisfaction. For men, body mass index (BMI; β = 0.76, P < 0.01), physical activity score (β = - 0.11, P < 0.01), and restrained eating score (β = 0.10, P < 0.01) were the significant factors predictive of body dissatisfaction. For women, BMI (β = 0.57, P < 0.01), muscle mass (β = 0.12, P < 0.01), physical activity score (β = - 0.11, P < 0.01), and restrained eating score (β = 0.09, P < 0.01) were the significant factors predictive of body dissatisfaction.
University students with high body dissatisfaction had lower physical activity scores and higher restrained eating scores. The data presented here highlight the impact of university students' body dissatisfaction on physical activity deficiency and disordered eating behaviors in China.
随着肥胖发病率的增加，肥胖与身体意象之间的关系已成为全球热门研究课题。从高中到大学，年轻人所处的社会环境发生了变化。大学生饮食失调和身体活动不足的发病率较高。本研究旨在探讨中国南方大学生的身体不满、身体活动不足与饮食失调行为之间的关系。
共招募了 1296 名 18-23 岁的大学生参加本研究。参与者完成了人体测量学指标、体力活动评定量表-3（PARS-3）和中荷饮食行为问卷（C-DEBQ）的测量。大学生通过问卷报告了理想体重和体型。
与男性相比，年轻女性的身体不满程度更高。对于男性，身体质量指数（BMI；β=0.76，P < 0.01）、身体活动得分（β=-0.11，P < 0.01）和约束性进食得分（β=0.10，P < 0.01）是身体不满的显著预测因素。对于女性，BMI（β=0.57，P < 0.01）、肌肉质量（β=0.12，P < 0.01）、身体活动得分（β=-0.11，P < 0.01）和约束性进食得分（β=0.09，P < 0.01）是身体不满的显著预测因素。
身体不满程度较高的大学生身体活动得分较低，约束性进食得分较高。这里呈现的数据突出了中国大学生身体不满对身体活动不足和饮食失调行为的影响。
