Artigo Original Avaliação do conhecimento e hábitos de fotoproteção entre crianças e seus cuida­ dores na cidade de Porto Alegre, Brasil Evaluation of the knowledge and photoprotection habits of children and their caregivers in the city of Porto Alegre, Brazil

Introduction: Childhood is considered a critical period for photoprotection, since approximately 80% of the exposure to the sun occurs during this phase of life. Objectives: To evaluate the characteristics of the knowledge and sun protection habits of children and their caregivers. Methods: A cross sectional study was conducted with questionnaires from October 2011 to July 2012. Results: 177 children (mean age = 7.66 years); 64.9% of children assessed exposure to the sun as dangerous, 88.7% knew what sunscreen is, and 94.3% considered its use important; however, 66.6% believed it was necessary only in summer. Regarding photoprotection habits, 37.3% reported exposure to the sun between 10a.m. and 4p.m. Among caregivers, 81.3% reported an absence of daily application of sunscreen on their children, and 33.9% reported that their children had already had some type of sunburn. Conclusions: Strong dissociation between knowledge and practice regarding exposure to the sun was observed in the present study. The discrepancy between knowledge and habits that was observed in the two groups can be explained by the quality of information on exposure to the sun. The present study’s data point to the need for a wider dissemination of adequate knowledge, both by the media and by physicians, to nurture healthy practices regarding exposure to the sun.
