To determine the seroprevalence of HIV infection and hepatitis C among inmates of a federal penitentiary for women.
Voluntary, anonymous, linked, point-prevalence study involving testing of blood samples for antibodies to HIV and hepatitis C virus.
All inmates of the multilevel security federal Prison for Women, Kingston, Ont., who volunteered to participate in the study. Inmates at this long-stay facility are from across Canada.
Seroprevalence rate among participants of antibodies to HIV and hepatitis C virus.
Of the 130 inmates available for study 113 (86.9%) agreed to donate a blood sample. One woman (0.9%) was HIV positive; 45 (39.8%) were positive for hepatitis C antibody.
It is possible to obtain a high participation rate in a voluntary, anonymous, linked point-prevalence study in a long-stay penitentiary. The HIV seroprevalence rate of 0.9% is lower than that found in studies in provincial (short-stay) prisons. However, the high rate of antibodies to hepatitis C suggests a significant level of risk behaviour, most likely injection drug use, and suggests the potential for a rapid increase in the rate of HIV infection should the number of newly admitted HIV-positive inmates who use injection drugs rise.
确定一所联邦女子监狱中囚犯的艾滋病毒感染和丙型肝炎血清流行率。
一项自愿、匿名、关联的现患率研究，涉及检测血样中的艾滋病毒和丙型肝炎病毒抗体。
安大略省金斯顿市多层安全级别的联邦女子监狱中所有自愿参与该研究的囚犯。该长期关押设施中的囚犯来自加拿大各地。
参与者中艾滋病毒和丙型肝炎病毒抗体的血清流行率。
在130名可供研究的囚犯中，113名（86.9%）同意捐献血样。一名女性（0.9%）艾滋病毒呈阳性；45名（39.8%）丙型肝炎抗体呈阳性。
在长期关押的监狱中进行自愿、匿名、关联的现患率研究，有可能获得较高的参与率。0.9%的艾滋病毒血清流行率低于在省级（短期关押）监狱研究中发现的流行率。然而，丙型肝炎抗体的高流行率表明存在显著程度的危险行为，很可能是注射吸毒，这表明如果新入狱的注射吸毒艾滋病毒阳性囚犯数量增加，艾滋病毒感染率可能会迅速上升。
