RESUMEN
OBJECTIVES: Skin cancer (melanoma and non-melanoma) is the most common cancer in humans, with melanoma being the most aggressive. Due to the fact that ultraviolet (UV) radiation exposure is the only adjustable aetiological factor, UV protection is the essential preventive measure. Based on these grounds, a study was conducted in order to compare three population groups with different levels of knowledge about UV protection, as well as to determine any differences in sun exposure habits, and the level of awareness of the damaging effects of the sun on the skin. MATERIALS AND METHODS: An observational, cross-sectional study was conducted using a questionnaire survey of 317 Spanish university students aged 18-25years old, between October and December 2015. Descriptive statistics methods and Pearson's Chi-squared were used. RESULTS: Six questions were used to evaluate the sun exposure habits. Significant differences were detected in two of them: mole self-assessment (P<.001) and the use of an appropriate sun protection factor (P=.025). Five questions were asked concerning the level of knowledge about UV protection, with differences (P<.001) being found in all cases. CONCLUSIONS: Despite having more knowledge about the risks of sun exposure in the medical dermatology students group, only two of the six habits questioned were improved. Other factors that could be involved are the aesthetic or sociocultural factors. The early prevention of skin cancer is essential, with health promotion programs needing to be established that take into account all these conditions.
