We surveyed first- through fifth-year undergraduate students in 20011 and again in 2006 for the prevalence of body art (piercing and tattooing) and the incidence of consequent medical complications including 10 class-years (1104 respondents, 97% response rate). Prevalences were 51% for body piercing and 23% for tattooing. Although no medical complications from tattoos were reported, medical complications from piercing occurred in 19% of students.
