One of the most important risk factors for melanoma is the number of acquired common and atypical nevi in childhood. The role played by neonatal blue-light phototherapy in the increasing incidence of common and atypical melanocytic nevi in childhood or adolescence has been discussed recently with discordant results.<\/jats:p>\n               <jats:p>PATIENTS AND METHODS. We designed a multicenter study to assess the effects of neonatal blue-light phototherapy on nevus count in a cohort of 9-year-old children. We counted back and arm nevi as a function of size in 828 children included in a French photoprotection educational campaign. History of neonatal phototherapy, phototype, skin, hair and eye color, and sunburn were assessed through questionnaires to which both parents and children responded, and a nevus count was performed by trained nurses blinded to phototherapy history.<\/jats:p>\n               <jats:p>RESULTS. Mean nevus count was 16.7 per child. Twenty-two percent of the children had received neonatal blue-light phototherapy. Neonatal phototherapy had no effect on the nevus count irrespective of nevi location, nevi size, or phototype of the children. A light phototype, skin, and hair color; blue\/green eyes; and history of sunburn were closely correlated with an increase in nevus count.<\/jats:p>\n               <jats:p>CONCLUSIONS. This study found no evidence for a major role of blue-light phototherapy on nevus count in 9-year-old children. It underlines the dominant effect of phototype characteristics and history of sunburn in childhood on the early development of melanocytic nevi.<\/jats:p>","DOI":"10.1542\/peds.2008-2986","type":"journal-article","created":{"date-parts":[[2009,4,27]],"date-time":"2009-04-27T13:17:09Z","timestamp":1240838229000},"page":"e896-e900","source":"Crossref","is-referenced-by-count":24,"title":["Neonatal Blue-Light Phototherapy Does Not Increase Nevus Count in 9-Year-Old Children"],"prefix":"10.1542","volume":"123","author":[{"given":"Emmanuel","family":"Mahe\u0301","sequence":"first","affiliation":[{"name":"Departments of Dermatology"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alain","family":"Beauchet","sequence":"additional","affiliation":[{"name":"Public Health, Ambroise Pare\u0301 University Hospital, Research Unit EA 4339, Skin, Cancer, and Environment, University of Versailles-Saint Quentin en Yvelines, Assistance Publique-Ho\u0302pitaux de Paris, Boulogne-Billancourt, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Philippe","family":"Aegerter","sequence":"additional","affiliation":[{"name":"Public Health, Ambroise Pare\u0301 University Hospital, Research Unit EA 4339, Skin, Cancer, and Environment, University of Versailles-Saint Quentin en Yvelines, Assistance Publique-Ho\u0302pitaux de Paris, Boulogne-Billancourt, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Philippe","family":"Saiag","sequence":"additional","affiliation":[{"name":"Departments of Dermatology"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"417","published-online":{"date-parts":[[2009,5,1]]},"reference":[{"key":"2021120902401410300_R1","doi-asserted-by":"crossref","unstructured":"Jemal A, Siegel R, Ward E, Murray T, Xu J, Thun MJ.
