Abstract/OtherAbstract:
Our aim was to examine the association between ethnicity, phenotype, sun behaviour and other characteristics, and constitutive and relative facultative skin pigmentation. 191 participants were recruited, with a mean age of 7.6 years (SD 3.4), during 2009-2011 from Maternal and Child Health Centres and schools in Melbourne, Australia. Parental questionnaire data were obtained on sun behaviour and examination consisted of noting the child's natural skin, hair and eye colour, ethnicity, naevi count and spectrophotometric melanin density (MD). Constitutive skin pigmentation was estimated from buttock MD. Relative facultative skin pigmentation was estimated by hand compared to buttock absorption. Ethnicity, hair colour and skin colour were associated with constitutive and facultative skin pigmentation on univariate analysis. Higher ambient UVR in the past month, greater freckling, greater naevi and increased sun exposure over the past year were related to darker facultative skin pigmentation. Sun exposure over the life-course was not. The two skin charts accounted for 39.7% and 21.4% of buttock MD, respectively. Relative facultative skin pigmentation is associated with recent UVR levels, not life-course sun exposure. Relative facultative skin pigmentation may not be a useful measure of sun exposure over the early life-course. Skin colour charts can be used to assess constitutive skin pigmentation if spectrophotometry is not available. © 2013 Wiley Periodicals, Inc.
