Impact of a sun protection campaign in Medellín (Colombia)

Abstract

To evaluate the impact of an educational massive sun protection campaign. Two telephone surveys were performed to 707 participants, on knowledge about the hours of greater solar intensity, UV protection devices, the ultraviolet index, and the history of skin cancer. Between the first and the second survey, a massive sun protection campaign was carried out. A sun protection brochure was also sent to each participant. In the first survey (S1) a total of 707 individuals were interviewed, while in the second one (S2), the effectiveness of the calls decreased to 374 people. Nevertheless, we found significant differences between the first and the second survey (chi(2) = 12.3, P = 0.006). Overall, a significant increment in sun protection knowledge was acquired, but the use of sun-block remained stable. The knowledge about what the UVI means was increased significantly from S1 to S2. The best communication means to increase the overall knowledge about the sun and its effects were the brochure and TV. We should encourage massive sun protection. The role of women in the transmission of these messages to their children or family nucleus is essential. Also, we should encourage the elaboration of brochures and an appropriate television use for health messages. Dermatologists must have a role in controlling skin topics presented on television to avoid erroneous messages or inadequate attitudes.
