Study: Sun Seeking and Vitamin D

PEOPLE AT GREATEST RISK FOR SKIN CANCER STILL SEEK THE SUN TO GAIN VITAMIN D BENEFITS, ACCORDING TO HOLLINGS CANCER CENTER STUDY

Findings Highlight Mixed Messages about Risks and Benefits of Sun Exposure

July 15, 2010, Charleston, SC – The media message about vitamin D, “the sunshine vitamin,” is reaching the general public.  Approximately one-third of people surveyed, including those at greatest risk for skin cancer, were aware of intentionally seeking the sun in hopes of increasing their body’s production of vitamin D, and of these two out of five were actually engaging in sun-seeking behavior to increase Vitamin D levels.

The study, led by Anthony Alberg, PhD, MPH, associate director for Cancer Prevention and Control at the Hollings Cancer Center at the Medical University of South Carolina, have been published in the July/August issue of Public Health Reports.

Key findings of the study of over 8,000 people:

  • 30% of the people surveyed were aware that going into the sun unprotected leads to increase    productionof vitamin D.
  • Of those who were aware that unprotected sun exposure increased the body’s synthesis of vitamin D, 42% were actually engaging in sun-seeking to increase their body’s vitamin D production.  People who had a personal history of skin cancer were just as likely as those who did not to intentionally spend unprotected time in the sun for vitamin D.

“The conflicting messages emerging from the biomedical research community about vitamin D  are a big controversy right now,” Alberg said. “On the one hand, there is concern about the erosion of skin cancer prevention behaviors, particularly among those at high risk of skin cancer.  On the other hand, there is concern that vitamin D levels in the population are on average too low.”

Vitamin D has well-established benefits for bone health, helping to form and maintain strong bones. There are many other hypothesized health benefits of vitamin D that are still being tested, such as for hypertension, cancer, and several autoimmune diseases.

“We do not want people to increase their risk of developing skin cancer simply to increase their vitamin D levels,” Alberg added. “Taking a vitamin D supplement provides a sensible alternative source of the ‘sunshine vitamin.'”
