Background Asbestos-contaminated soil has been used by people for many years in the rural part of Anatolia. However, there is no program to control usage of asbestos in this region. Objective To determine the knowledge and awareness level about asbestos in a region where asbestos-related diseases are endemic due to environmental exposure to asbestos in the rural setting. Methods This study included 760 participants, recruited using non-probability sampling, who were classified into four groups according to residence and asbestos exposure type (urban, rural; asbestos-exposed, asbestos-unexposed). Asbestos knowledge and awareness was measured via the Asbestos Knowledge and Awareness Questionnaire (AKAQ). The cut-off value of questionnaire was determined by the K-means cluster analysis for sufficient and insufficient knowledge and awareness level. A multiple logistic regression analysis was performed to determine independent factors affecting sufficient knowledge and awareness of participants about asbestos. Results The median and mean score of the AKAQ in study group were 30 and 33.9, respectively. The urban asbestos-exposed group had a higher score than the urban asbestos-unexposed and both rural groups (p < 0.001). Factors affecting asbestos knowledge and awareness were education status (p = 0.035), asbestos exposure (p = 0.003) and living in the rural area (p = 0.005). Sufficient knowledge and awareness (score > 45) was higher among participants who had graduated from university and had asbestos exposure. Insufficient knowledge and awareness level was higher among participants living in rural areas. Conclusion In this region of Anatolia, knowledge and awareness level of asbestos was low among people at risk for environmental asbestos exposure. People should be aware of asbestos and its hazards by a well-designed training program and be monitored for asbestos-related diseases.
