Indoor tanning is a public health threat,1 and the Surgeon General has called for its reduction in adolescents and young adults.2 Research on indoor tanning has not distinguished between tanning-only salons vs other businesses and private residences that provide tanning (ie, nonsalon tanning). For example, gyms often offer free tanning, which may lead to riskier tanning habits.3 Better understanding of nonsalon tanning could have policy, prevention, and clinical implications. Our study addresses this literature gap by examining the prevalence and correlates of nonsalon tanning in a nationally representative sample of young women, who have the highest rates of indoor tanning use.
