Health sciences, and in particular Nutrition and Dietetics students, have been shown to exhibit an increased prevalence of disordered eating. The aim of the present cross-sectional study was to evaluate other specified feeding and eating disorders (OSFEDs), including stress-related eating, food addiction, and orthorexia, in relation to the dietary intake, among nutrition/dietetics students.
A total of 176 undergraduate students from a Department of Nutrition and Dietetics, in Greece, participated in the study. Dietary intake was recorded, and the prevalence of Eating and Appraisal Due to Emotion and Stress (EADES), food addiction (with the modified Yale Food Addition scale mYFAS), and orthorexia were assessed. Chi-square and t tests were performed between sexes, orthorexic and non-orthorexic students, as well as between food-addicted and non-addicted participants. Multiple linear regression analysis assessed relationships between energy intake, BMI or waist circumference, and the food-related psychometric scales.
Among participating students, 4.5% had food addiction and 68.2% demonstrated orthorexia. No differences were observed between men and women, concerning the prevalence of food addiction and orthorexia, the sum of mYFAS symptoms, or individual EADES factors. Orthorexic students exhibited increased BMI, reduced energy, and saturated fat intake. In addition, orthorexic men consumed more vegetables. Multiple linear regression analysis revealed that orthorexic behavior was associated with increased BMI, waist circumference and energy intake. Lower BMI was associated with increasing ability to cope with emotion-and-stress-related eating and increasing appraisal of ability and resources to cope with emotions and stress. Emotion-and-stress-related eating was negatively associated with BMI. Appraisal of ability and resources to cope with emotions and stress was associated with the energy intake. Finally, age was positively correlated with the appraisal of outside stressors/influences, indicating increased ability to cope with outside stressors among older students.
The study shows that despite the suggested interventions, the problem of OSFEDs among nutrition and dietetics students is still valid. Regular screening, counseling, and education is needed to reduce its prevalence.

已有研究表明，健康科学专业，尤其是营养与饮食学专业的学生，饮食失调的患病率有所上升。本横断面研究的目的是评估营养/饮食学专业学生中其他特定的进食和喂养障碍（OSFEDs），包括与压力相关的进食、食物成瘾和orthorexia（健康食品强迫症）与饮食摄入量之间的关系。
希腊一所大学营养与饮食学系的176名本科生参与了该研究。记录饮食摄入量，并评估因情绪和压力导致的进食和评估（EADES）、食物成瘾（使用改良的耶鲁食物成瘾量表mYFAS）以及orthorexia的患病率。对性别、orthorexic学生和非orthorexic学生以及食物成瘾者和非成瘾者进行卡方检验和t检验。多元线性回归分析评估能量摄入、BMI或腰围与食物相关心理测量量表之间的关系。
在参与研究的学生中，4.5%有食物成瘾，68.2%表现出orthorexia。在食物成瘾和orthorexia的患病率、mYFAS症状总和或个体EADES因素方面，男女之间未观察到差异。orthorexic学生的BMI升高，能量和饱和脂肪摄入量降低。此外，orthorexic男性摄入更多蔬菜。多元线性回归分析显示，orthorexic行为与BMI、腰围和能量摄入增加有关。较低的BMI与应对情绪和压力相关进食的能力增强以及应对情绪和压力的能力和资源评估增加有关。情绪和压力相关进食与BMI呈负相关。应对情绪和压力的能力和资源评估与能量摄入有关。最后，年龄与外部压力源/影响的评估呈正相关，表明年龄较大的学生应对外部压力源的能力增强。
研究表明，尽管有建议的干预措施，但营养与饮食学专业学生中的OSFEDs问题仍然存在。需要定期进行筛查、咨询和教育以降低其患病率。
