Abstract
Objectives: Incense burning is a well-known practice in Asian and Middle Eastern cultures for ceremonial and religious purposes. The excessive use of incense burning has become a critical environmental health concern. The incense sellers are more exposed to incense allied air pollution. This study examines the association between prediabetes and type 2 diabetes mellitus (T2DM) in incense sellers.
Methods: This cross-sectional prevalence study was conducted in the Department of Physiology, College of Medicine, King Saud University, Riyadh, Saudi Arabia" during the period July 2019 to January 2020. After medical history and examinations had been performed, a total of 265 non-smoking volunteers male incense sellers were selected. American Diabetes Association (ADA) criteria were followed, people with "HbA1c less than 5.7% were considered normal; HbA1c 5.7%-6.4% were pre-diabetics, and HbA1c > 6.4% were considered people with diabetes". In shops, the incense sellers were exposed to incense-related pollution for 8 hours daily, seven days a week. The mean age for the participants was 25 +/- 5.5 years, and body mass index was 19 +/- 2.8 (kg/m)(2).
Results: In incense sellers, the pre-diabetic was 125 (47.2%), and diabetes was 75 (28.3%). However, 65 (24.5 %) incense sellers were without prediabetes and diabetes. There was an increase in HbA1c levels with increasing working exposure to incense shops.
Conclusions: The prevalence of pre-diabetic and type-2 diabetes was increased in incense sellers. The prevalence of pre-diabetic and type-2 diabetes was further increased with the increasing working duration of incense sellers. The study findings call for safe practice and avoiding indoor burning incense. It is suggested that well-ventilated areas with proper masks for the workers may reduce the incense-related pollution effects.
