Factors Associated with Sunbed use in Women: the E3N-SunExp Study.

OBJECTIVES: In this study, we attempt to describe the profile of sunbed users among cancer-free French women.

METHODS: E3N is a prospective cohort including 98,995 French women aged 40- 65 years in 1990. In 2008, a specific UV questionnaire was sent to all reported skin cancer cases and 3 controls per case, matched on age, county of birth, and education. We used logistic regression models adjusted for pigmentary traits.

RESULTS: Compared with non-users, ever-users of sunbeds were younger (ptrend < .0001), had higher levels of education (ptrend = .0004) and income (ptrend = .002), and were more likely to be divorced/separated (OR = 1.58). They were more likely to be smokers (OR = 1.59) or former smokers (OR = 1.64), had higher alcohol intakes (ptrend = .001), and lower physical activity levels (OR = 0.54), although they had a lower BMI (ptrend = .004) and a thinner body shape (ptrend = .006). Sunbed users were also more likely to report many freckles (ptrend = .01) and sunburns in adulthood (ptrend = .008), to use sunscreen (SPF<8: OR = 2.15), and to renew sunscreen application (sometimes: OR = 1.49).

CONCLUSIONS: Sunbed use is associated with intentional sun exposure and several unhealthy behaviors. Our findings call for further re- search towards the development of targeted prevention campaigns to reduce sunbed use.
