RESUMEN
BACKGROUND AND OBJECTIVE: The SolSano (HealthySun) project is a primary school sun education program that has been running in Aragon, Spain, since 2000. In the short term, it has proven to be effective at promoting sun protection behaviors and heightening awareness in childhood. The aim of this study was to evaluate the long-term effectiveness of the SolSano program. PARTICIPANTS AND METHODS: Retrospective, observational, analytical, cohort study of students at the University of Zaragoza between 2015 and 2016. The students answered a previously validated, purpose-designed, online questionnaire. We calculated descriptive statistics for all variables and performed bivariate and multivariate analyses to test for differences between students who had attended a primary school that ran the SolSano program and those who had not. RESULTS: Data for 324 students were analyzed. Mean age was 22.9 years and 78% of the respondents were women. In total, 44% of the students had participated in the SolSano program at primary school. Half of the respondents (50.5%) had experienced 1 or 2 sunburn episodes the previous summer. Significant differences were only observed for some aspects addressed by the questionnaire between SolSano participants and nonparticipants. CONCLUSIONS: This is the first study to evaluate the long-term effectiveness (15 years) of a primary school sun protection program. The absence of significant differences in our sample might be explained by non-continuation of the program into adolescence and the existence of sun protection campaigns outside the school.
