2021
Background: Homeless people are prone to sexually transmitted and blood-borne infectious diseases such as hepatitis B, hepatitis C, and HIV due to their risky behaviors and low awareness of various diseases. Objectives: Thus, the present research aimed to examine the epidemiologic patterns of HBV, HCV, HIV, and related factors among the homeless population of Zahedan in 2019. Methods: A cross-sectional study was conducted on a total of 329 homeless people. Eligible people were selected using a convenience sampling method from homeless individuals residing in care centers affiliated with the Welfare Organization and the Health Deputy of Zahedan University of Medical Sciences. Data on the demographic and behavioral characteristics of the cases were collected through a structured questionnaire completed in face-to-face interviews. A 10 cc blood sample was taken from each of the cases for serological tests of hepatitis B, hepatitis C, and HIV. The test results and collected data were entered in SPSS16 software. Logistic regression analysis and chi-square tests were used to analyze the data. Results: The majority of the cases (84%) were males, and 59% were in the age-group of 35 - 50 years. Of the subjects, 93% had a history of drug abuse, 74% reported a history of smoking, and 45% had tattoos. The prevalence of hepatitis C, hepatitis B, and HIV was 13%, 2.7%, and 0.3%, respectively (only one case of HIV was identified). In a multi-variate model, imprisonment history [OR = 2.32 (1.08 - 4.98)], history of sexual abuse [OR = 3.73 (1.36 - 10.26)], being widowed or divorced [OR = 2.83, (1.21 - 6.64)], and history of injection with shared needles and syringes [OR = 5.11 (1.97 - 13.28)] remained the predicting factors of hepatitis C. Conclusions: Based on the obtained results of the study, homeless people are more prone to infections with HCV, HBV, and HIV due to their risky behaviors. Therefore, a need is highlighted for preventive interventions and developing the level of health literacy in this group regarding behaviors contributing to the aforementioned infections.
