La Paz, capital of Bolivia, with 3.600m of altitude, gathers favorable conditions for the development of this research whose main objective was to evaluate the behavior of the UVI levels and number of new cases of FTD in the period 1998-2012. Information on FTD cases has been collected from the Central Polyclinic of the Hospital "Caja Nacional de Salud"(CNS). The UV-R information was obtained by Brewer spectrophotometer. A descriptive evaluation of the incidence rates of FTD, UVI and Minimum Erythematosus Dose (MED) was performed. Generalized estimation equations were used to estimate the relative risk of FTD by sex and age group. It was observed that, regardless of the time of the year, at around midday, 94.6% of the UVI records corresponded to the "Very High and Extreme" scales, the MED for phototype IV (450Jm-2) was soon reached in the first two hours of the day. In summers, the accumulated erythremic daily dose (AED) reached a maximum of 12.950 Jm-2 . In the study period, 12.153 cases of FTD were recorded, of which 63.7% corresponded to females. The average Incidence Rate (IR) was 31 cases per 100.000 inhabitants, showing a 4.7-fold higher risk in the elderly compared to 0 to 4 years. It is concluded that there is a need to adopt policies and strategies of protection education according to the reality of La Paz cityAttribution 3.0 Brazilhttp://creativecommons.org/licenses/by/3.0/br/Radiação ultravioletaÍndice ultravioletaFotodermatosesarticle10.5935/1984-2295.20170022
