Indoor tanning continues to grow in popularity even though empirical investigations denounce the behavior. Various reports have illustrated the detrimental health effects of ultraviolet (UV) exposure including increased risk for skin cancer. According to some physicians, the risk may be especially high for adolescents whose skin cells are dividing and changing rapidly. Persistent use of tanning facilities has become especially apparent within adolescent female populations. The purpose of this systematic literature review was to assess pertinent, empirical studies to answer the question, "What are the determinants of indoor tanning behavior among adolescent females?" Assessment of the methodological quality of each study is also presented. Consistent results from all studies demonstrated that girls were 2-3 times more likely to tan indoors than boys. Age, skin type, attitudes, beliefs, demographics, and social factors were among the determinants identified throughout the literature. Suggestions for future research and intervention are also included. (Contains 1 table.)
