This study aims to explore the association between restrained eating, body image, and dietary intake among Chinese college students. This cross-sectional study included 1301 college students at two universities in Hunan Province. Electronic questionnaires were used to collect information including students' demographic characteristics, restrained eating, perception of body weight, body satisfaction, and dietary intake. Anthropometric measurements were collected to calculate body mass index (BMI). The prevalence of high restrained eating was 52.8%. Students who were dissatisfied with their bodies or overestimated their body weight showed a higher tendency toward high restrained eating ( < 0.05). Students with high restrained eating tended to eat fruits and eggs more frequently, while the frequency of eating domestic animals and poultry, sugar-sweetened beverages, and fast food were the opposite. Moreover, high restrained eating was a risk factor for low dietary diversity (odds ratio (OR) = 1.384, 95% confidence interval: 1.002~1.912). The high incidence of restrained eating among Chinese college students and its energy-restricted diets that may lead to possible health implications require attention. Further studies are needed to investigate the characteristics of college students' restrained eating to tailor appropriate interventions for forming positive body images and promoting healthy eating behaviors, thus, improving dietary quality.
本研究旨在探讨中国大学生的节制饮食、身体意象与饮食摄入之间的关联。这项横断面研究纳入了湖南省两所大学的1301名大学生。采用电子问卷收集学生的人口统计学特征、节制饮食、对体重的认知、身体满意度及饮食摄入等信息。收集人体测量数据以计算体重指数（BMI）。高节制饮食的发生率为52.8%。对自己身体不满意或高估自己体重的学生表现出更高的高节制饮食倾向（<0.05）。高节制饮食的学生更倾向于频繁食用水果和鸡蛋，而食用家畜和家禽、含糖饮料及快餐的频率则相反。此外，高节制饮食是饮食多样性低的一个危险因素（优势比（OR）=1.384，95%置信区间：1.002~1.912）。中国大学生中节制饮食的高发生率及其可能导致健康问题的能量限制饮食需要引起关注。需要进一步研究调查大学生节制饮食的特点，以便制定适当的干预措施，塑造积极的身体意象并促进健康的饮食行为，从而提高饮食质量。
