Eating disorders are regarded to be associated with many psychological and behavioral problems. Moreover, adolescence has been reported to be the key period for developing eating habits, and eating disorders typically emerge in adolescence and early adulthood. This study aimed to investigate the prevalence of eating disorders and explore the associated factors among adolescents in Hunan province, China METHODS: A total of 1610 middle school students from Hunan province, China, were enrolled in this study. The participants were aged from 11 to 16 years old. The following data were collected: demographic variables, Body Mass Index (BMI), suicidal behaviors, non-suicidal self-injury, depression, anxiety, stress (depression - anxiety - stress scale, DASS-21), childhood trauma (Childhood Trauma Questionnaire, CTQ), symptoms of social anxiety (Social Anxiety Scale-Adolescents, SAS-A), and eating problems (Eating Attitudes Test, EAT-26).
The estimated prevalence of eating disorders was 8.9%. Compared with participants without eating disorders, participants with eating disorders were more likely to be at a younger age, obese and overweight, and have a history of non-suicidal self-injury, suicidal ideation, suicidal plans, suicide attempts, emotional abuse, physical abuse, emotional neglect, and physical neglect; more likely to experience stress, anxiety or depression as well as have high scores of social avoidance and distress related to general social contexts. Anxiety, emotional neglect, physical neglect, obesity, and overweight were still significant in the binary logistic regression model after controlling for confounding factors. Additionally, younger age, emotional abuse, physical abuse, stress, anxiety, depression, social avoidance, and distress related to general social contexts were significantly correlated with the EAT-26 scores in correlation analysis CONCLUSIONS: Eating disorders are quite common among middle school students. Moreover, eating disorders are associated with younger age, non-suicidal self-injury, suicidal ideation, suicide attempts, stress, anxiety, depression, emotional abuse, physical abuse, emotional neglect, physical neglect, social avoidance, and distress related to general social contents and BMI. This study provides a reference for school counselors and clinicians in the prevention and treatment of eating disorders.
饮食失调被认为与许多心理和行为问题有关。此外，青春期被报道是养成饮食习惯的关键时期，饮食失调通常在青春期和成年早期出现。本研究旨在调查中国湖南省青少年饮食失调的患病率，并探讨相关因素。
本研究共纳入 1610 名来自中国湖南省的中学生。参与者年龄在 11 至 16 岁之间。收集了以下数据：人口统计学变量、体重指数（BMI）、自杀行为、非自杀性自伤、抑郁、焦虑、压力（抑郁-焦虑-压力量表，DASS-21）、儿童创伤（儿童创伤问卷，CTQ）、社交焦虑症状（青少年社交焦虑量表，SAS-A）和饮食问题（饮食态度测试，EAT-26）。
饮食失调的估计患病率为 8.9%。与无饮食失调的参与者相比，有饮食失调的参与者更年轻、肥胖和超重，且有非自杀性自伤、自杀意念、自杀计划、自杀企图、情感虐待、身体虐待、情感忽视和身体忽视的病史；更有可能经历压力、焦虑或抑郁，以及在一般社交环境中具有较高的社交回避和苦恼分数。在控制混杂因素后，焦虑、情感忽视、身体忽视、肥胖和超重仍在二元逻辑回归模型中具有统计学意义。此外，在相关性分析中，年轻、情感虐待、身体虐待、压力、焦虑、抑郁、社交回避和与一般社交环境相关的苦恼与 EAT-26 评分显著相关。
饮食失调在中学生中较为常见。此外，饮食失调与年龄较小、非自杀性自伤、自杀意念、自杀企图、压力、焦虑、抑郁、情感虐待、身体虐待、情感忽视、身体忽视、社交回避和与一般社交环境相关的苦恼以及 BMI 有关。本研究为学校辅导员和临床医生在预防和治疗饮食失调方面提供了参考。
