Knowledge deficit, attitude and behavior scales association to objective measures of sun exposure and sunburn in a Danish population based sample

<div><p>The objective of this study was to develop new scales measuring knowledge and attitude about UVR and sun related behavior, and to examine their association to sun related behavior objectively measured by personal dosimetry. During May-August 2013, 664 Danes wore a personal electronic UV-dosimeter for one week that measured their UVR exposure. Afterwards, they answered a questionnaire on sun-related items. We applied descriptive analysis, linear and logistic regression analysis to evaluate the associations between the questionnaire scales and objective UVR measures. Perceiving protection as routine and important were positively correlated with protective behavior. <i>Knowledge deficit of UV and risk of melanoma</i>, <i>perceived benefits</i> and <i>importance of protection behavior</i> was also correlated with use of protection. ‘<i>Knowledge deficit of UV and risk of melanoma</i> and <i>Perceived barrier towards sun avoidance between 12 and 15’</i> were both associated with increased risk of sunburn. <i>Attitude towards tan</i> was associated to both outdoor time and exposure as well as use of protection, but not to sunburn. The results regarding <i>Knowledge deficit of UV and risk of melanoma</i> associated to UVR exposure and <i>Perceived barrier towards sun avoidance between 12 and 15</i> emphasize the importance of awareness of melanoma risk and the priority of the skin cancer prevention advice. Shifting activities to outside the suns peak-hours could be an approach for structural and campaign preventive measures. Knowledge of items predicting exposure to UVR, use of protection and sunburn are important for planning of preventive interventions and melanoma research.</p></div
