title: Sunbed use in Swedish urban adolescents related to behavioral characteristics.
abstract: BACKGROUND
  Sunbed use among Swedish adolescents has not been extensively studied, nor has the social learning process associated with it. The purpose of this study was to explore Swedish adolescents' sunbed use in relation to sex, age, smoking, perceived physical attractiveness, attitudes to artificial and natural UV exposure, psychosomatic symptoms, and risk knowledge.
  
  
  METHODS
  In the spring of 1993, 60 school classes comprising 1,502 students ages 14-19 were randomly selected to answer a questionnaire concerning sunbed use and sunbathing habits, smoking, perceived physical attractiveness, psychosomatic symptoms, and need for information about and knowledge of the risks of UV exposure.
  
  
  RESULTS
  Of 1,252 respondents, 57% had used sunbeds (females 70%, males 44%) > or = four times during the previous year. A marked increase (P < 0.001) in both sunbed use and smoking was detected between the 8th and the 9th grade (at ages 14-15). Sunbed use was also significantly correlated with sex, age, excessive tanning in natural sunlight, and low perceived physical attractiveness. The need for information on risks of high UV exposure was greatest among the best informed students and among students with high UV exposure (sunbed use, excessive tanning in natural sunlight).
  
  
  CONCLUSIONS
  It seems doubtful whether further information on UV risks would result in altered behavior among highly exposed students, who seem receptive to information and have good knowledge. For a better understanding of the mechanisms underlying the association between sunbed use, smoking, and self-esteem, more in-depth, qualitative studies are required.
