Description
Asmaa Mohammad Ahmad Mohammad, Rabab Ahmed Abd El-Hai Hammad, and Noha M Elghazally studied nail biting among medical students in Egypt, in a 2025 paper. Nail biting, called onychophagia, is a repetitive habit often tied to stress, worry, and perfectionism. The team asked how common it is at Tanta University and what traits go with it.
They surveyed 330 students with a set of questions plus a standard stress scale. About fifty-seven percent said they actively bit their nails, with the habit a bit more common in men, though that gap was not firm. Among nail biters, smoking, a family history of the habit, and fear of public spaces each showed clear links. Stress scores, though, did not differ between biters and non-biters. The authors suggest habit-focused help for students.
