[目的]探索针对MSM人群在开展艾滋病行为干预中如何确定和利用IEC信息。[方法]对291名男男性行为者进行问卷调查,根据知晓率和影响率建立干预指数模型。[结果]8个艾滋病相关知识/信息条目的干预信息指数(IECI)≥20.0,12个条目的IECI﹤10.0;知识类的条目中低IECI比例为58.8%,而信息类条目中的高IEC比例为62.5%。[结论]IECI可以反映艾滋病干预中信息需求的强度,建议采用IECI筛选艾滋病行为干预有效知识/信息,采用高IECI的8个条目在成都MSM人群中开发IEC材料并开展预防干预活动。
[Objective] To explore how to identify and utilize IEC information for MSM population in AIDS behavioral intervention. [Methods] A total of 291 MSM were surveyed, and the intervention index model was established according to the awareness rate and impact rate. [Results] The intervention information index (IECI) of 8 AIDS-related knowledge / information items was ≥20.0, IECI <10.0 of 12 items, and the proportion of low IECI in knowledge-based items was 58.8%, while the high IEC proportion 62.5%. [Conclusion] IECI can reflect the intensity of information needs in AIDS intervention. It is suggested that IECI should be used to screen effective knowledge / information on AIDS behavioral interventions. IEC material should be developed using 8 items with high IECI in IEC MSM in Chengdu and preventive interventions should be conducted.
