In several studies from northern Europe, north America and Australia, @entity8205 are correlated with pigmentary traits and with intense sun exposure in a way similar to @entity320 . However, it is unclear if these data can be extrapolated to populations in other geographic locations and with different prevalent phenotypes. Our study was conducted among schoolchildren aged 13-14 years in 16 Italian cities. The parents of 3,127 @entity1 of a total of 3,160 (99%) consented to our study. A structured questionnaire was used to collect information about sun exposure and lifetime history of sunburns. @entity1 were also examined by trained dermatologists to assess pigmentary traits and to make a count of @entity8205 . The median nevus density was higher among @entity1 than @entity1 . Areas that are usually chronically exposed to the sun exhibited a higher density of nevi compared to intermittently and rarely exposed areas. A higher density of nevi was found in @entity1 with lighter skin, blond hair and blue eyes. Red-haired @entity1 had a remarkably lower nevus density compared to the other color categories. The density of nevi increased with an increased number of reported episodes of sunburns. The results concerning nevi >/=6 mm in diameter paralleled those obtained for the total nevus density. However, at variance with total nevus density, a significant relation was also observed between larger nevi and freckling. Our study confirms that, in Italian schoolchildren, there is a relation between pigmentary traits, history of sunburns and the density of @entity8205 . @entity8205 and @entity320 share a similar risk factor profile.

The density of XXXX correlates with constitutional variables and history of sunburns: a prevalence study among Italian schoolchildren.
