The ethnic and geographical variations of AIDS prevalence among injection drug users (IDU) have highlighted the need to understand the role of the relevant risk factors in specific subpopulations of IDU. In this study we examine the factors related to seropositivity among IDU entering drug detoxification facilities in metropolitan San Juan, Puerto Rico.
From October 1990 until August 1991, 390 IDU were interviewed. Four groups of risk factors were examined: sexual practices, drug injection behaviours, risk behaviours while in US Mainland cities, and while incarcerated. A stepwise logistic regression model was used to simultaneously assess the independent effects of the behavioural risk factors on HIV seropositivity.
Of the 342 IDU who were tested for HIV antibodies, 29.5% were seropositive. The behaviours found to be associated with seropositivity were: having sex with an IDU in the last 6 months; having injected drugs for over 5 years; and injecting with used needles while incarcerated.
Public health programmes will need to establish more effective collaborative links with correctional institutions in order to reduce the spread of HIV among IDU in Puerto Rico.
注射吸毒者中艾滋病流行情况的种族和地域差异凸显了了解相关风险因素在特定注射吸毒者亚人群中作用的必要性。在本研究中，我们调查了波多黎各圣胡安大都市地区进入戒毒所的注射吸毒者中与血清学阳性相关的因素。
1990年10月至1991年8月，对390名注射吸毒者进行了访谈。研究了四组风险因素：性行为、药物注射行为、在美国大陆城市期间的风险行为以及监禁期间的风险行为。采用逐步逻辑回归模型同时评估行为风险因素对HIV血清学阳性的独立影响。
在342名接受HIV抗体检测的注射吸毒者中，29.5%为血清学阳性。发现与血清学阳性相关的行为有：在过去6个月内与注射吸毒者发生性行为；注射毒品超过5年；以及在监禁期间使用用过的针头注射。
公共卫生项目需要与惩教机构建立更有效的合作联系，以减少波多黎各注射吸毒者中HIV的传播。
