背景：2006 年 7 月和 9 月，在针对肯尼亚 46 个疟疾地区 0-59 个月大的儿童 (CU5) 的活动中，免费分发了 340 万张长效驱虫蚊帐 (LLIN)。分发后一个月进行了一项调查，以评估谁收到了 LLIN 活动、谁拥有经过杀虫剂处理的蚊帐和通过其他渠道收到的其他蚊帐，以及这些蚊帐的使用情况。评估了针对高风险目标群体以满足床帐拥有和使用目标的分配策略的可行性。方法：采用分层、两阶段整群调查，以与规模成比例的概率对地区和普查区进行抽样。使用带有全球定位系统 (GPS) 的手持电脑 (PDA) 来开发抽样框架，引导访谈员返回选定的家庭，并收集调查数据。 结果：在目标区域，67.5%（95% CI：64.6，70.3%）的 CU5 家庭接受了活动 LLIN。包括以前拥有的蚊帐在内，所有拥有 CU5 的家庭中 74.4%（95% CI：71.8，77.0%）拥有蚊帐。超过一半的 CU5（51.7%，95% CI：48.8，54.7%）在前一天晚上睡的是驱虫蚊帐。近 40% (39.1%) 的家庭收到了活动网，将杀虫剂蚊帐的家庭总体拥有率提高到 50.7%（95% CI：48.4，52.9%）。结论：该活动成功覆盖了目标人群，即 CU5 家庭，即最容易感染疟疾的风险群体。有针对性的分配战略将有助于肯尼亚实现指标目标，但需要与其他战略相结合，以实现所需的人口覆盖水平。
Background: In July and September 2006, 3.4 million long-lasting insecticide-treated bed nets (LLINs) were distributed free in a campaign targeting children 0-59 months old (CU5s) in the 46 districts with malaria in Kenya. A survey was conducted one month after the distribution to evaluate who received campaign LLINs, who owned insecticide-treated bed nets and other bed nets received through other channels, and how these nets were being used. The feasibility of a distribution strategy aimed at a high-risk target group to meet bed net ownership and usage targets is evaluated.Methods: A stratified, two-stage cluster survey sampled districts and enumeration areas with probability proportional to size. Handheld computers (PDAs) with attached global positioning systems (GPS) were used to develop the sampling frame, guide interviewers back to chosen households, and collect survey data.Results: In targeted areas, 67.5% (95% CI: 64.6, 70.3%) of all households with CU5s received campaign LLINs. Including previously owned nets, 74.4% (95% CI: 71.8, 77.0%) of all households with CU5s had an ITN. Over half of CU5s (51.7%, 95% CI: 48.8, 54.7%) slept under an ITN during the previous evening. Nearly forty percent (39.1%) of all households received a campaign net, elevating overall household ownership of ITNs to 50.7% (95% CI: 48.4, 52.9%).Conclusions: The campaign was successful in reaching the target population, families with CU5s, the risk group most vulnerable to malaria. Targeted distribution strategies will help Kenya approach indicator targets, but will need to be combined with other strategies to achieve desired population coverage levels.
