Abstract

Objective: To determine if exposure to atmospheric ozone disruption and other factors are associated with photodermatoses in the high-altitude pediatric population in Peru. Materials and Methods: A cross-sectional study based on data obtained from studies of dermatological diseases among the population exposed to mine tailings in Peru which included children under the age of 18 in 6 population centers located over 2500 meters above sea level (m.a.s.l). We evaluated the presence of photodermatoses and possible associated factors obtaining the adjusted odds ratio (aOR) and confidence intervals (CI). Results: 594 children below the age of 18 participated in this study, 53.0% girls, the average age was 10.4 ± 4.1 years. 51.3% were exposed to a mini hole in the ozone layer, 60.1% resided at an altitude over 3500 m.a.s.l and 51.9% presented cutaneous manifestations of atopy upon physical examination. The prevalence of photodermatoses was 64.8%, of which the most frequent were actinic prurigo (49.3%), pityriasis alba (18.5%) and actinic cheilitis (4.4%). The multivariate analysis found that residing in a region exposed to the mini hole in the ozone layer (aOR = 4.23; CI 95%: 2.32–7.72) and residing at an altitude over 3500 m.a.s.l (aOR = 2.76; CI 95%: 1.57–4.86) were both independent associated factors to photodermatoses. Conclusion: A high prevalence of photodermatoses exists among the pediatric population living at high-altitude in Peru. Residing in a region exposed to a mini hole in the ozone layer and residing over 3500 m.a.s.l constituted associated factors.
