Background and Objective: Microplastic pollution is recognized as a major environmental threat, and individuals’ Knowledge, attitudes, and behaviors play a crucial role in its prevention. This study aimed to assess the levels of Knowledge, attitudes, and preventive behaviors of students at Khoy University of Medical Sciences toward microplastic pollution.
Materials and Methods: This cross-sectional study was conducted among students of Khoy University of Medical Sciences. All enrolled students (n = 550) were invited to participate using a voluntary census-based approach, of whom 400 completed the questionnaire. After excluding incomplete responses, data from 372 participants were included in the final analysis. Data were collected using a two-part questionnaire comprising demographic characteristics and a researcher-developed instrument assessing knowledge, attitude, and practice (KAP) regarding the prevention of microplastic pollution. Content validity was confirmed using the content validity ratio (CVR) and content validity index (CVI), and reliability was established through test–retest analysis (ICC = 0.78) and internal consistency (Cronbach’s alpha = 0.83–0.95). Data were analyzed using Pearson correlation and ordinal logistic regression in STATA version 15.
Results: The findings indicated that students’ levels of knowledge and preventive behaviors were predominantly moderate, while their attitudes toward preventing microplastic pollution were mostly positive. Ordinal logistic regression analysis showed that higher levels of knowledge (OR = 3.98, 95% CI = 1.91–8.28)and positive attitudes (OR = 14.96, 95% CI = 7.26–30.83) significantly increased the likelihood of engaging in preventive behaviors. In addition, younger age (OR = 9.41, 95% CI = 1.26–7.29), being married (OR = 3.03, 95% CI = 3.33–26.52), higher maternal educational level (OR = 2.99, 95% CI = 1.24–7.17), and father's employment status (OR = 1.67, 95% CI = 1.02–2.73) were identified as demographic factors effective in promoting preventive behaviors.
Conclusion: The results suggest that enhancing Knowledge and fostering positive attitudes considerably improve preventive behaviors against microplastic pollution among students. Therefore, implementing targeted educational programs focusing on increasing knowledge and strengthening positive attitudes is essential for promoting preventive practices and mitigating the environmental impacts of microplastics.
