Predictors of hepatitis B vaccination in women prisoners in two prisons in England.
BACKGROUND
Hepatitis B is an important public health issue, especially in the female prison population. The high prevalence in this population is largely accounted for by the high rates of injecting drug use and the fact that these women are more likely to exchange sex for drugs or money and practice unprotected sex. There is a national programme in English prisons to vaccinate everyone against Hepatitis B. This study aimed to investigate whether women who had been in prison before were more likely to have been vaccinated against hepatitis B and whether contact with community services was more likely to predict hepatitis B vaccination.


METHODS
A questionnaire survey of new entrants into two women's prisons in England.


RESULTS
Four hundred and eighty seven out of 613 women approached completed the questionnaire and gave complete data on hepatitis B vaccination status, giving a response rate of 79.4%. One hundred and thirty three women (27.3%) had received at least three vaccinations against hepatitis B. Previous imprisonment and intravenous drug use were independent predictors of vaccination. Six months or more in prison greatly increased an individual's odds of being immunized [odds ratio 12.01 (95% confidence interval (CI) 5.53-26.10)]. Registration with a general practitioner (GP), contact with drug or alcohol services and exchanging money or goods for sex were not independently associated with vaccination status.


CONCLUSIONS
Prisons play an important role in the delivery of hepatitis B vaccination. However, this should not prevent providers of health services making greater efforts to engage this marginalized group and to ensure that they receive an appropriate level of healthcare in the community.
