OBJECTIVE To identify risk factors associated with HCV infection in Islamabad–Rawalpindi. METHODS Fifty‐seven cases and 180 controls were enrolled from various departments of the nine major hospitals of the Rawalpindi–Islamabad during July–September 1998. Cases were enzyme‐linked immunosorbent assay (ELISA) positive for antibodies to HCV (anti‐HCV), aged 20–70 years, and residents of Islamabad or Rawalpindi division. Controls were anti‐HCV ELISA negatives of the same age range and from the same area. A structured questionnaire was used to collect data on demographic variables and potential risk factors, which was analysed by logistic regression to calculate crude and adjusted odds ratios (OR) and corresponding 95% confidence intervals (CI) for risk factors. RESULTS The final multivariate logistic regression model revealed that after adjusting for age, cases were more likely to have received therapeutic injections in the past 10 years (1–10 vs. 0 therapeutic injections; adjusted OR=2.8, 95% CI: 1.1–7.1; > 10 vs. 0 therapeutic injections; adjusted OR=3.1, 95% CI: 1.2–7.9) and were significantly more likely to have daily face (adjusted OR=5.1, 95% CI: 1.5–17.0) and armpit shaves (adjusted OR=2.9, 95% CI: 1.3–6.5) by a barber. CONCLUSION HCV control and prevention programs in this region should include safe injection practices and educate men about the risk of HCV infection from contaminated instruments used by barbers.
