BACKGROUND: Nevus density in children, a well-known risk factor for malignant melanoma, depends both on constitutional factors and on previous ultraviolet (UV) exposure. Secular trends of childhood UV exposure could thus be indirectly monitored by repeated standardized surveys assessing nevus density in children, such as the "childhood monitoring of nevus density (CMONDE-Study)".
METHODS: Two complete surveys comprising all children at the time of school enrolment were performed in the city and county of Göttingen, Germany, during the years 1999 and 2000. A total of 4252 children with a median age of 6.25 years were examined as part of the mandatory school enrolment health assessment, and complete data were available for 3881 children.
RESULTS: Median nevus density was 5.8/m(2) in the entire study group. The subgroup-specific median increased from "Fitzpatrick skin type" IV to II, but the density was not increased for the type I subgroup. Similarly, nevus density rose with increasing lightness of hair color, but was very low in red-haired individuals. While the number of freckles was also strongly associated with nevus density, the association between iris color and skin reflectance, respectively, was weak. The duration of the additional examination for CMONDE was on average 3-5 min per child.
CONCLUSION: We regard CMONDE as a highly feasible surveillance instrument, which should be implemented as an important addition to regular regional or national health reporting.
