As part of the evaluation of a community-level HIV prevention program for women, this study examined predictors of exposure to print media and community outreach and assessed the relationship between exposure to the intervention and condom use behavior. Data from interviews with 479 women randomly selected from the intervention community in 1995 and 1996 were examined. Analysis of demographic and risk characteristics were conducted to identify predictors of exposure to the project's HIV prevention messages. Additionally, logistic regression analyses were conducted to examine the effects of intervention exposure on condom use, controlling for factors related to exposure. The results revealed that the print media campaign reached the largest number of women. However, women at highest risk did not have high rates of exposure to print media, but had greater exposure to outreach. Exposure to print media had an effect on increased communication with a main partner about condom use, but was not significantly related to condom use last time had sex. There were no significant main effects for exposure to outreach on condom use behavior. An important finding of this analysis was that each intervention strategy was successful in reaching a different portion of the target population and that exposure had differential effects on the condom use behavior of particular segments of the target population.
作为一项针对女性的社区层面艾滋病毒预防项目评估的一部分，本研究考察了接触印刷媒体和社区外展服务的预测因素，并评估了接触干预措施与避孕套使用行为之间的关系。研究分析了1995年和1996年从干预社区随机抽取的479名女性的访谈数据。对人口统计学和风险特征进行了分析，以确定接触该项目艾滋病毒预防信息的预测因素。此外，进行了逻辑回归分析，以检验干预接触对避孕套使用的影响，并控制与接触相关的因素。结果显示，印刷媒体宣传活动覆盖的女性人数最多。然而，风险最高的女性接触印刷媒体的比例并不高，但接触外展服务的比例更高。接触印刷媒体对增加与主要伴侣关于避孕套使用的沟通有影响，但与上次性行为时使用避孕套并无显著关联。接触外展服务对避孕套使用行为没有显著的主要影响。该分析的一个重要发现是，每种干预策略都成功覆盖了目标人群的不同部分，并且接触对目标人群特定部分的避孕套使用行为有不同影响。
