Many indoor tanning businesses require parental consent for teenagers to use their facilities, but most would allow young tanners more than the government-recommended amount of exposure during the first week, according to a report in the September issue of Archives of Dermatology, one of the JAMA/Archives journals. Facilities with specific state laws regarding parental consent or accompaniment were more likely to require these steps.
"Exposure to UV radiation from indoor tanning lamps has been linked with both melanoma and squamous cell cancer, and first exposure before age 35 years may increase melanoma risk by as much as 75 percent," the authors write as background information in the article.
Indoor tanning is especially popular among adolescent girls in the United States, which may contribute to the recently reported increase in melanoma rates among U.S. women ages 15 to 39. As of 2005, 28 states had laws regulating indoor tanning, including 21 with youth access restrictions.
Approximately 87 percent of the facilities required teens to get parental consent, about 14 percent required a parent to accompany the tanner and 5 percent would not allow a 15-year-old to tan at all. "State law and youth access law each were significantly related to parental consent and parental accompaniment, with facilities in states with a law more likely to require these than facilities in states without such a law," the authors write.
Only around 11 percent of the facilities limited teens to the FDA-recommended three or fewer sessions the first week. The average number of sessions allowed the first week was 6.02, and about 71 percent of facilities reportedly indicated they would allow a teen to tan seven days a week.
