Orthorexia nervosa (ON) is defined as the excessive attention on healthy eating, and studies especially focused on food quality ON prevalence in university students can be extremely variable. The objective of this study is to investigate whether there was a difference in ON risk between health-scientific, economic-humanistic, sport sciences and dietetics and nutrition students, and to evaluate if lifestyle-related ON risk factors (dieting, physical activity, drugs and supplements use) could have an impact in different ways in determining ON risk among students attending these four programs. Participants were recruited at the University of Pavia and received a two-section questionnaire including demographic and lifestyle information and the ORTO-15 questionnaire. A total of 671 students (54% F e 46% M) completed the questionnaire (median age 21.00 (IQR 20.00−23.00), median BMI 21.77 kg/m2 (IQR 20.06−23.66 kg/m2)). The 31.2% had ORTO-15 test scores < 35, and were considered at risk of having ON. No differences were found in ON risk among the students attending the four university courses. Dieting was confirmed as the major ON risk factor for health-scientific, economic-humanistic and sport sciences students. The type of sport practiced was an important determinant of ON risk only for the economic-humanistic course, while supplements use was statistically different between sport sciences students with or without ON. Our findings may suggest that lifestyle-related risk factors of orthorexia can differ among the students of distinct university courses, but these results need to be supported by further longitudinal and prospective studies.
饮食强迫症（ON）被定义为对健康饮食的过度关注，尤其是针对大学生食品质量 ON 患病率的研究结果差异极大。本研究旨在调查健康科学、经济人文、运动科学和营养与饮食学专业学生的 ON 风险是否存在差异，并评估与生活方式相关的 ON 风险因素（节食、体力活动、药物和补充剂使用）是否会以不同方式影响不同专业学生的 ON 风险。参与者在帕维亚大学被招募，并接受了包括人口统计学和生活方式信息以及 ORTO-15 问卷的两部分问卷调查。共有 671 名学生（54%为女性，46%为男性）完成了问卷（中位数年龄 21.00（IQR 20.00-23.00），中位数 BMI 为 21.77 kg/m2（IQR 20.06-23.66 kg/m2））。31.2%的学生 ORTO-15 测试得分<35，被认为存在 ON 风险。在参加四门大学课程的学生中，ON 风险无差异。节食被确认为健康科学、经济人文和运动科学学生的主要 ON 风险因素。所从事的运动类型是经济人文课程学生 ON 风险的重要决定因素，而补充剂的使用在有或没有 ON 的运动科学学生之间存在统计学差异。我们的发现表明，与生活方式相关的 orthorexia 风险因素可能因不同大学课程的学生而异，但这些结果需要进一步的纵向和前瞻性研究来支持。
