Ziehfreund S, et al. - Researchers analyzed data obtained from a systematic review of articles indexed for MEDLINE on PubMed via selected MeSH terms and keywords related to topics, as well as a hand search of publications between January 1, 2012, and December 31, 2018, in order to: provide an updated overview of primary prevention against keratinocyte carcinoma (KC)—including skin cancer-related knowledge, attitudes, and sun protection behavior (SPB) of outdoor workers, the general population, and medical professionals—and assess the effectiveness and acceptability of sun-protection programs. In all, they found substantial differences with distressing consequences—including subjects who had not even heard about skin cancer before—in sun-related knowledge and attitude. They noted variations in SPB among the involved studies, whereas no study provided an overall sufficient SPB in their examined sun protection measures. However, sun-protection interventions using new technologies appeared to have great potential to increase sun-related knowledge and SPB.
