Exposure to ultraviolet radiation from the sun is the most important source of vitamin D, but is also a risk factor for skin cancer. People who worried about their vitamin D status were more likely to have altered their sun protection behaviors and spent more time in the sun than those not worried about vitamin D. Use of novel item response theory analysis highlighted the potential impact of such behavior change on skin cancer predisposition. The strongest determinants of self-reported sun protection behavior changes due to vitamin D concerns were attitudes and location, with people at higher latitudes worrying more.
