Sun Exposure and Usage of Sun Protection: Knowledge, Perception and Practice among University Students

Abstract

Background: Exposure to the sun is vital for the body but is associated with problem ranging from pigmentation to cancer. Therefore, knowledge about protective measures is critical. This study aims to assess undergraduate students’ knowledge, perception and practices towards the adverse effects of sun exposure and the usage of sun-protective measures. Methods: A cross-sectional study was conducted between 1 September 2022 and 20 September 2022 using a web-based questionnaire. Undergraduate students from medical and non-medical colleges in Iraqi universities participated in this study. Descriptive and inferential statistics and logistic regression were performed to analyse the data. Results: A total of 655 students participated in this study. The knowledge level of more than one-half of the students (53%) was inadequate. Approximately three-quarters of the study sample used sunscreens products. Skin type was the main factor in choosing the appropriate sunscreen product. Media and advice from specialists were the main factors affecting participants’ usage of sunscreens. Gender (females), college (medical), year(s) of study (sixth), residence (urban), daily sun exposure (1 h–3 h) and less-than-normal vitamin D levels were found to be significantly associated with better knowledge (P-value < 0.05). Age, gender, being a student in medical colleges and not knowing vitamin D levels were found to be significant predictors of participants’ knowledge. Conclusion: The low level of knowledge reported among the participants’ calls for more attention from health authorities in educating the public about the harmful effects of sun exposure and the importance of adopting protective measures.
