目标。居住在贫困的市中心社区的妇女感染艾滋病毒的风险很高。一项随机、多地点社区层面的HIV预防试验在美国5个城市的IS低收入住房开发项目中进行。通过在两个时间点对690名妇女进行调查，评估了基线和12个月随访人群的风险特征。在9个干预条件住房开发项目中，开展了社区层面的干预，包括减少艾滋病风险讲习班和由同龄人中的民意领袖妇女开展的社区艾滋病预防活动。干预后2个月内发生无保护性行为的比例由50%降至37.6%，安全套保护性行为比例由30.2%上升至47.2%。在接受干预活动的女性中，在过去2个月中，无保护性行为的平均频率在随访时(平均值=4.0)低于基线时(平均值=6.0)。其他风险指标的变化也证实了这些变化。让妇女参与以社区为基础的艾滋病毒预防活动的社区一级干预措施可以减少高危性行为。
Objectives. Women in impoverished inner-city neighborhoods are at high risk for contracting HIV. A randomized, multisite community-level HIV prevention trial was undertaken with women living in IS low-income housing developments in 5 US cities.Methods. Baseline and 12-month follow-up population risk characteristics were assessed by surveying 690 women at both time points. In the 9 intervention condition housing developments, a community-level intervention was undertaken that included HIV risk reduction workshops and community HIV prevention events implemented by women who were popular opinion leaders among their peers.Results. The proportion of women in the intervention developments who had any unprotected intercourse in the past 2 months declined from 50% to 37.6%, and the percentage of women's acts of intercourse protected by condoms increased fi om 30.2% to 47.2%. Among women exposed to intervention activities, the mean frequency of unprotected acts of intercourse in the past 2 months tended to be lower at follow-up (mean = 4.0) than at baseline (mean = 6.0). These changes were corroborated by changes in other risk indicators.Conclusions. Community-level interventions that involve and engage women in neighborhood-based HIV prevention activities can bring about reductions in high-risk sexual behaviors.
