Lack of Knowledge and Misperceptions on Photoprotection among Brazilian Youngsters release_2zhpn3ln2bfapkarya66hsifw4

Abstract

Daily photoprotection (PhP) is essential in preventing harmful effects from solar ultraviolet radiation (UVR) exposure. For that reason, we interviewed students aged from 4 to 20 years old about their knowledge on sun exposure and PhP habits. Age, sex, family income, and skin phototype were statistically related to the proposed questions. Our results show that Brazilian youngsters do not have the habit of wearing long-sleeved clothing (<15% in summer), sunglasses (0.0%), or hats (2.1%). More than 40% had no knowledge about ultraviolet index (UVI), while another 30% misinterpreted what it is. Less than half of all students wear sunscreen when out in the sun. Despite this low PhP use-rate, more than 90% know that UVR causes skin cancers. Low income was the factor that showed the greatest number of significant relationships with respect to the lack of PhP. The findings suggest that current traditional PhP campaigns are not efficient. We propose that PhP should be part of school curricula from elementary school onwards. After all, the lack of educational programs predisposes these youngsters to an increased chance of skin diseases in the future.
