Background: Tattooing is among identified risk factor for blood-borne diseases., Objective: This study aims to determine the prevalence of tattooing during lifetime and in prisons and its related factors among Iranian prisoners., Methods: This is a cross-sectional study. The required data was obtained from hepatitis B and C surveillance surveys in prisons in 2015-2016 that was collected through face-to-face interview. 12,800 prisoners were selected by multi-stage random sampling from 55 prisons of 19 provinces in Iran. Weighted prevalence and associated factors (using Chi-Square test and multivariate logistic regression) were determined by Stata/SE 14.0 survey package., Results: Out of 12,800 prisioners, 11,988 participated in the study (93.6% participation rate). The prevalence of tattooing in lifetime and in prisons was 44.7% and 31.1% respectively. The prevalence of tattooing during lifetime was significantly associated with age<35 years, being single, illiteracy, history of imprisonment, drug use, piercing during lifetime, extramarital sex and history of STI; the prevalence of tattooing in prison had a significant association with history of imprisonment, drug use, piercing in prison, and history of extramarital sex (p<0.05)., Study Limitations: Information and selection bias was one of the study limitations., Conclusion: The results of this study showed that the prevalence of tattooing during lifetime and in prison among prisoners was significantly high especially in high-risk groups such as drug users and sexually active subjects. Given the role of tattooing, drug injection and sex in the transmission of blood-borne diseases, harm reduction programs are recommended to reduce these high-risk behaviors in prisons., (Copyright © 2020.

This study aimed to investigate the prevalence and correlates of hepatitis C virus infection among injecting drug users in a community-based setting in Tehran, Iran. In October 2004, injecting drug users were recruited from a drop-in centre and neighboring parks and streets in a drug-populated neighborhood in Tehran. Participants were interviewed using a structured questionnaire, and a sample of oral mucosal transudate was collected for detection of HIV and HCV antibodies. Overall, 105 of 202 participants (52.0%) were found to be positive for HCV-antibody testing. After adjustment for the basic demographic characteristics, the prevalence of HCV infection was found to be associated with length of drug injection (more than 10 years) [odds ratio (OR), 3.25; 95% confidence interval (CI), 1.43-7.38], length of lifetime incarcerations (more than a year) (OR, 3.44; 95% CI, 1.68-7.06), and a history of being tattooed inside prison (OR, 1.96; 95% CI, 1.06-3.62). High prevalence of HCV infection and its association with incarceration-related exposures are important implications for harm reduction initiatives for drug using inmates in Iran. While prevention interventions for drug using inmates are being expanded in Iran, it is important that high prevalence of HCV infection be taken into consideration in order to control further transmission of this infection.

This was a cross-sectional prevalence study to determine the prevalence of hepatitis C virus (HCV) and high-risk behaviours in drug abusers admitted to prison in Guilan province, northern Islamic Republic of Iran. Subjects were asked about risk behaviours for acquiring HCV and blood was drawn for HCV antibody testing using ELISA techniques. Of 460 inmates, the mean duration of drug use was 8.9 years; 51.7% were opium users and 18.3% heroin users. HCV risk behaviours were common in this population and 209 inmates (45.4%) were HCV antibody positive (88.9% of intravenous drug abusers). HCV-positive status was significantly associated with intravenous drug use, having skin tattoos and number of times in prison.
