Frequency of Acquired Melanonevocytic Nevi and Their Relationship to Skin Complexion in 939 Schoolchildren

Abstract

In 939 schoolchildren aged 8–16 years skin complexion was determined by a system of seven categories. Anamnestic data concerning tanning ability and history of sunburns, however, were not considered owing to their obvious unreliability in children. Mean nevus count was 17.97 was significantly higher in boys than in girls and increased with age. There was a clear relation of mean nevus number and skin complexion: in fair skin type nevi are most frequent decreasing in number by increasing of pigment content. Additionally, children with freckles have higher mean nevus count in every category of skin complexion. All literature data critically reviewed as dealing with mean mole count are not comparable in several respects. In different races however such studies may serve as a basis for subsequent investigations concerning the questions of probably increasing number of melanonevocytic nevi.

The Prevalence of Common Acquired Melanocytic Nevi and the Relationship With Skin Type Characteristics and Sun Exposure Among Children in Lithuania

“…Most researchers 7,13,21,[30][31][32] have found a higher number and density of MN in boys compared with girls, and we found the same tendency in our study. Boys aged 9 to 10 years had more MN of all sizes compared with girls, while male adolescents aged 14 to 15 years had more MN, both of all sizes and MN 2 mm of larger.…”

Risk factors of incident melanocytic nevi: A longitudinal study in a cohort of 1,232 young German children

“…Moreover the susceptibility to develop MN depends on skin complexion and populations with pigmentary traits that protect the skin more effectively against solar radiation develop fewer nevi. 14,35,36 In our study, there was a clear association of ethnicity of parents with MN counts in children in the cross-sectional 19 and longitudinal analysis. Most non- …”

Body-Site Distribution of Melanocytic Nevi in Young Australian Children

“…Children from Townsville have total body and site-specific MN counts and densities that are higher than those reported for children the same age or slightly older from other Australian states 13,27 and abroad, 11,12,[28][29][30] even though the prevalence of MN is similar at birth. 31,32 This may be partly explained by geographic differences in ambient solar UV radiation and annual temperature variation, which influences the length of the season during which clothing offering little protection from the sun is worn.…”
