PURPOSE: Despite recent increases in the popularity of tattooing, little is known about the prevalence and characteristics of adults who have ever been tattooed. We investigated demographic and behavioral correlates of ever getting tattooed in an adult population. METHODS: Computer-assisted telephone interviews were completed by a representative sample of 8656 men and women ages 16-64 years in Australia. RESULTS: A total of 14.5% of respondents had ever been tattooed, and 2.4% of respondents had been tattooed in the year before the interview. Men were more likely than women to report a tattoo, but the highest rates of tattooing were found among women in their 20s (29.4%). Men and women ages 20-39 were most likely to have been tattooed, as were men with lower levels of education, tradesmen, and women with live-out partners. Tattooing was also associated with risk-taking behaviours, including smoking, greater numbers of lifetime sexual partners, cannabis use (women only) and ever having depression (men only). CONCLUSIONS: Tattooing has increased in popularity during the past decade. Yet tattoos still appear to be a marker for risk-taking behavior in adults.
