LOZA, A; SIMI, M  y  IRIBAS, J L. Knowledge of melanoma and sun-protective practices in patients at José M. Cullen Hospital of Santa Fe, Argentine. Rev. argent. dermatol. [online]. 2011, vol.92, n.3. ISSN 1851-300X.

Background. Melanoma is one of the deadliest forms of skin cancer, showing an increasing incidence worldwide over the past years. The aim of this study was to assess people's knowledge about melanoma, and their protective measures against UV radiation, considering that two-thirds of melanoma cases are associated to sun exposure. General objective. To assess the knowledge about melanoma and the sun protective practices in patients who attended the Department of Dermatology and in those admitted to the General Internal Medicine Unit of José M. Cullen Hospital. Material and methods. It was an observational, prospective, longitudinal, descriptive study. A sample of 275 participants aged between 16-85 years was included, composed of voluntary patients from the Department of Dermatology and inpatients from the General Internal Medicine Unit of José M. Cullen Hospital. The Statistical Package for the Social Sciences 15.0 software was used to make a descriptive analysis; the chi-square test was performed with a significance level of p < 0.05 to determine the statistical association among qualitative variables. Results. The knowledge was poor, since only 53% of respondents associated melanoma to skin cancer correctly. Hats were the most used sun protection choice, specially in men (p < 0.001). The use of sunscreen was more common among women (p= 0.003) - in fact, they were the ones who used it more regularly (p= 0.011) last summer - and among people under 40 (p= 0.002). Using long clothing was more common in men (p= 0.006) and in people over 40 (p= 0.002). A significant result was found between the use of SPF and its daily reapplication (p < 0.001), between not using any sun protection element and considering that a mole can develop skin cancer (p= 0.014). Conclusion. There is little knowledge among people, which is reflected on the inadequate protective practices against UV radiation.
