RESUMO:
In recent years several studies have shown that ultraviolet radiation (R-UV) causes impacts in several areas, among them, human health and climatology. The cities of La Paz - Bolivia and Natal - Brazil, are characterized by high R-UV fluxes throughout the year. These cities have typical and proper characteristics: Natal is a coastal city with a tropical climate, while La Paz is located at altitude above 3,600 m in the Andes. The main objectives of this work were: 1) to evaluate the behavior of R-UV levels by means of the ultraviolet index (UVI); the Minimum Erythemical Dose (DEM) and the Cumulative Erythema Dose (DEA) determination, in the cities of La Paz and Natal, between 1997 and 2012; 2) to perform a description of the main climatic characteristics of these cities that can identify potential factors that could justify such high levels of radiation and 3) to evaluate the incidence of photodermatoses (FTD) observed in La Paz, seeking its possible association with climatic factors. The information on FTD cases in the city of La Paz was collected at the Central Polyclinic of the Hospital "Caja Nacional de Salud" (CNS). The R-UV information was obtained by Brewer spectrophotometers, installed in both locations. Regarding the human health area, the generalized estimation equations were used to determine the relative risk of FTD by sex and age group and so the incidence rates of FTD were evaluated. About the intensity of the R-UV, it was carried out a validation of the information collected by the spectrophotometers through modeling. It was observed that, regardless of the time of the year, around midday, the IUV records corresponded to the "Very High and Extreme" scales in the two cities. The DEM for phototypes IV (450 Jm-2) was reached already in the first two hours of the day. In summers, the DEA reached a maximum of 12,950 Jm-2 in La Paz and 7,546 Jm-2 in Natal. In La Paz, there were 12,153 cases of FTD, of which 63.7% were female. The average Incidence Rate (TI) was 31 cases per 100,000 inhabitants, showing a 4.7 times higher risk in the elderly compared to the 0 to 4 year age range. One of the main difficulties in the development of this research was the access to health information in Natal in a reference hospital (Hospital Universitário Onofre Lopes - HUOL-UFRN) due to the fact that the research would have to be submitted to an ethics committee for evaluation and/or approval. However, there was no guarantee of approval. In order to not postpone the study, it was decided to restrict the analysis of the clinical cases only to the city of La Paz. Concerning the health of the population in La Paz it is emphasized that the incidence of FTD in the female sex is greater in relation to the male, with special emphasis on the age group of 15 to 59 years. It is concluded that there is a need to adopt educational policies and strategies for individual protection, both in La Paz and in Natal, due to the exposure of the populations of these cities to the high fluxes of R-UV observed in soil.
