Frequency of hepatitis B and C seropositivity in prisoners.
Biomedica Jan ;22(1):55-8.

This study was conducted on prisoners of Central Jail, Bahawalpur and on blood donors at Blood Bank Bahawal Victoria Hospital (BVD), Bahawalpur from Ist August 2005 to 30th November 2005. The intension was to study the seroprevalence of hepatitis B and C in prisoners and to note risk factor if any predisposing to the infection. All the prisoners of central jail Bahawalpur present during the study period, aged more than 18 years of either sex were included as the study group and a comparative group was blood donors presenting to blood bank BVH, Bahawalpur during this period. All the cases in study group (2086) as well as control group (9714) were screened for hepatitis B (HBs Ag) and hepatitis C (anti-HCV) infection detected on serum by One Step Test Device. All the positive cases were confirmed by Enzyme Linked Immunosorbant Assay. After an explanation, verbal consent was taken and a questionnaire was filled before taking samples from all the study group cases. On the basis of screening, prisoners were de vided into seropositive group and sero-negative group. The different variable applied on both the groups were age, sex, occupation, residence, marital status, self shaving / by barber, family history of (H/o) jaundice, H/o blood trans-fusion, operation, tattooing and body piercing, drug abuse, same sex/ extramarital sex and hepatitis B vaccination status. Total prisoners screened were 2086. Out of them 2072 were males (99.3%). Mean age was 34 years. Total seropositive cases were 249 (11.9%) While during the same period seropositivity in blood donors (control group) was 5.9%. Seropositivity of HBV was 5.6% in study group and 3.1% in control group (p<0.001), HCV was 6.3% Vs 2.8% (p<0.001), statistically very significant difference. Risk factors analysis among prisoners revealed that drug abuse was significantly associated with seropositivity (27% Vs 12%, p value <0.001). Among drug abusers, very high percentage of intravenous drug users was positive (89.2%, 25 out of 28). Prisoners shaved by barber were also a t higher risk than self shaving (p value <0.001). H/o operation (p<0.02) and rural origin (p<0.02) were other significant risk factors. Other risk factors evaluated were not statistically significant. Seroprevalence of hepatitis, both B and C is more in prison inmate than healthy blood donors. Main risk factor in them i is drug abuse, especially intravenous. Other significant risk factor is shaving by barber. There s a need to make some strategy to reduce the risk factors.
