Abstract

Objectives: Re-use of contaminated syringes, greater frequency of therapeutic injections, tattooing, and skin piercing have repeatedly been shown to be an important and independent risk factors for hepatitis B and C.

Methods: We estimated the population attributable risks (PARs) of various risk factors of HBV and HCV in our population using data from a nationally representative cross sectional survey conducted between July 2007 - May 2008 by Pakistan medical and research council (PMRC).

Results: Hepatitis B: Reducing the frequency of injections in last one year yield a PAR of 3.5%. Likewise, decreasing the practice of reuse of syringes will prevent 2.7% cases from our population. Eliminating the practice of shaving at barbers will avert 2.5% of new cases. Stopping sharing of smokeless tobacco gives the highest PARs and will prevent 4.4% of hepatitis B. Hepatitis C: Reducing the frequency of injections in last one year and decreasing the practice of reuse of syringes will avert 11.3% and 2.7% of cases respectively. Decreasing the practice of sharing of smokeless tobacco will preclude 8.1%of cases. Stopping tattooing will prevent 3.5% of cases. Similarly, practice of ear/ nose piercing among females yields PARs of 5.9%.

Conclusion: About one-third of the HBV and HCV cases in this Pakistani population could be prevented by the intervention on a few selected and modifiable risk factors.
