Abstract: 

Background: Hepatitis B virus (HBV) is likely to be more prevalent in certain populations and occupational groups, such as municipal solid waste workers (MSWWs).
Objectives: The current study aimed to estimate the prevalence of HBV and its risk factors among MSWWs compared to other municipal employees not exposed to waste.
Patients and Methods: The current cross-sectional study included 654 municipal employees in Zahedan (south-eastern Iran). A sample of blood was taken from each participant and tested for HBsAg through the enzyme-linked immunosorbent assay (ELISA). Demographic and other data on high risk behaviors were also collected through in-depth interviews. Data were analyzed using chi-square test and multiple regression analysis by STATA.
Results: The overall prevalence of HBV among municipal employees was 3.06% (95% CI: 1.70 - 4.30); however, it varied among the different employee subgroups as follows: 6.20% (95% CI: 2.70 - 9.70) in MSWWs, 3.3% (95% CI: 0.08 - 5.80) in drivers and 1% among staff who were not exposed to waste. Multiple regression analysis showed that exposure to waste [OR=9.36; 95% CI=2.01 - 43.7], lack of vaccination against HBV [OR=3.83; 95% CI=1.86 - 25.2], jaundice [OR=6.91; 95% CI=1.51 - 31.5], history of endoscopy [OR=2.86; 95% CI=1.08 - 7.62], and high risk behaviors [OR=4.80; 95% CI=1.96 - 27.2] were independently associated with HBV.
Conclusions: Greater encouragement for immunization against HBV as well as better education on HBV transmission routes and work safety precautions should be implemented to reduce the prevalence of HBV in MSWWs.
