Resum

ObjectiveTo examine the frequency and correlates of skin examination behaviors in an international sample of individuals at varying risk of developing melanoma.DesignA cross-sectional, web-based survey.SettingData were collected from the general population over a 20-month period on behalf of the Melanoma Genetics Consortium (GenoMEL).ParticipantsA total of 8178 adults from Northern (32%), Central (33%), and Southern (14%) Europe, Australia (13%), and the United States (8%).Main outcome measuresSelf-reported frequency of skin self-examination (SSE) and clinical skin examination (CSE).ResultsAfter adjustment for age and sex, frequency of skin examination was higher in both Australia (odds ratio [OR]SSE=1.80 [99% CI, 1.49-2.18]; ORCSE=2.68 [99% CI, 2.23-3.23]) and the United States (ORSSE=2.28 [99% CI, 1.76-2.94]; ORCSE=3.39 [99% CI, 2.60-4.18]) than in the 3 European regions combined. Within Europe, participants from Southern Europe reported higher rates of SSE than those in Northern Europe (ORSSE=1.61 [99% CI, 1.31-1.97]), and frequency of CSE was higher in both Central (ORCSE=1.47 [99% CI, 1.22-1.78]) and Southern Europe (ORCSE=3.46 [99% CI, 2.78, 4.31]) than in Northern Europe. Skin examination behavior also varied according to melanoma history: participants with no history of melanoma reported the lowest levels of skin examination, while participants with a previous melanoma diagnosis reported the highest levels. After adjustment for region, and taking into account the role of age, sex, skin type, and mole count, engagement in SSE and CSE was associated with a range of psychosocial factors, including perceived risk of developing melanoma; perceived benefits of, and barriers to, skin examination; perceived confidence in one's ability to engage in screening; and social norms. In addition, among those with no history of melanoma, higher cancer-related worry was associated with greater frequency of SSE.ConclusionsGiven the strong association between psychosocial factors and skin examination behaviors, particularly among people with no history of melanoma, we recommend that greater attempts be made to integrate psycho-education into the fabric of public health initiatives and clinical care, with clinicians, researchers, and advocacy groups playing a key role in guiding individuals to appropriate tools and resources.
