OBJECTIVES
This study compares the prevalence of Mantoux positivity among prisoners in NSW in 1996 and 2001 and examines factors associated with Mycobacterium tuberculosis infection.
DESIGN
Cross-sectional random samples of prisoners, including a longitudinal cohort of prisoners screened in both 1996 and 2001.
SETTING
29 correctional centres.
PARTICIPANTS
747 men and 167 women participated in the 2001 NSW Inmate Health Survey; a cohort of 104 prisoners from the 1996 and 2001 NSW Inmate Health Surveys.
RESULTS
The prevalence of Mantoux positivity remained stable between 1996 and 2001 (12% and 14%, p = 0.2), and increased among prisoners from Asian backgrounds (21% and 47%, p = 0.02). The annual risk of infection in the cohort among those detained continuously between 1996 and 2001 was 3.1%, and among recidivists it was 2.7% (p = 0.6).
CONCLUSION
The risk of M. tuberculosis infection for Australian prisoners is assessed to be approximately four times higher than that for the community, however there is no attributable risk to the prison environment itself.
目的
本研究比较了1996年和2001年新南威尔士州囚犯中结核菌素试验阳性的患病率，并研究了与结核分枝杆菌感染相关的因素。
设计
对囚犯进行横断面随机抽样，包括1996年和2001年都接受筛查的纵向队列囚犯。
地点
29个惩教中心。
参与者
747名男性和167名女性参与了2001年新南威尔士州囚犯健康调查；来自1996年和2001年新南威尔士州囚犯健康调查的104名囚犯队列。
结果
1996年至2001年期间，结核菌素试验阳性的患病率保持稳定（分别为12%和14%，p = 0.2），而亚洲背景的囚犯患病率有所上升（分别为21%和47%，p = 0.02）。1996年至2001年期间持续被拘留的队列中，每年的感染风险为3.1%，累犯中的感染风险为2.7%（p = 0.6）。
结论
据评估，澳大利亚囚犯感染结核分枝杆菌的风险约为社区人群的四倍，但监狱环境本身并无可归因风险。
