Phototypes I and II, freckles, a large number of acquired nevi, dysplastic nevi, and inadequate photoprotection appeared as risk factors with moderate strength for cutaneous malignant melanoma in the studied population. The color of the eyes and hair showed a very weak statistical significance as a risk factor. Sunscreens showed progressive significance corresponding to an increase in SPF, the best scores in statistical protection being achieved in users of sunscreens with SPF15 or greater. Frequent sunburn episodes appeared as the most important risk factor associated with malignant melanoma in this sample of the white population in southern Brazil.
