2011年，喀麦隆及其卫生伙伴分发了800多万顶免费长效驱虫蚊帐，以努力减少该国疟疾的严重发病率和死亡率。2011年7月发起了一项全国宣传运动，以确保在发放蚊帐时，蚊帐得到持续使用，以缩小蚊帐使用差距：在发放蚊帐前，至少有一顶蚊帐的家庭中，只有51.6%的成年人和63.4%的儿童睡在蚊帐下。即使在每两个人至少有一个蚊帐的家庭中，也有超过35%的成年人没有睡在蚊帐下。消灭疟疾组织调整了其标志性的“夜间观察”宣传方案，以配合协调一致的“KO Palu”（消灭疟疾）全国运动。本研究评估了KO Palu NightWatch活动（即由MNM NightWatch计划资助的KO Palu品牌通信的子集）对蚊帐使用的影响。本研究使用基线（2011年3月/4月，全国LLIN分发和KO Palu NightWatch启动之前）和干预后（2012年3月/4月）收集的全国调查数据，评估了接触KO Palu NightWatch活动的影响喀麦隆成年人及其五岁以下儿童昨晚的蚊帐使用情况。首先，通过比较2011年和2012年的蚊帐使用情况并测量KO Palu NightWatch的暴露量，建立了一个合理的因果关系案例;其次，通过模拟随机对照试验，使用倾向评分匹配（PSM）模型来估计暴露量对蚊帐使用的影响;最后，测试模型对不可测量因素的敏感性。PSM模型估计，在家中至少有一顶蚊帐的喀麦隆人中，接触KO Palu NightWatch活动与受访者昨晚使用蚊帐的增加6.6个百分点有关（65.7%对59.1%，P < 0.05），以及受访者5岁以下儿童昨晚使用蚊帐的比例增加了12.0个百分点（79.6% vs 67.6%，p < 0.025）。敏感性分析表明，只有一个非常小的风险，从遗漏的因素影响曝光和净使用的偏见。将PSM模型的结果外推到至少有一顶蚊帐的喀麦隆人口，这项分析估计，大约有298，000名成年人和超过221，000名五岁以下的儿童睡在蚊帐下，因为KO Palu NightWatch活动提供的知识，动机和/或及时提醒。该方案的费用为每一个得到保护的成年人不到0.16美元，每增加一个得到蚊帐保护的人不到1.62美元。研究结果表明，大众媒体传播干预措施在支持对长效驱虫蚊帐等疟疾控制商品的投资方面发挥着重要作用。
In 2011, Cameroon and its health partners distributed over eight million free long-lasting insecticide treated nets (LLINs) in an effort to reduce the significant morbidity and mortality burden of malaria in the country. A national communications campaign was launched in July 2011 to ensure that as the nets were delivered, they would be used consistently to close a net use gap: only 51.6% of adults and 63.4% of their children in households with at least one net were sleeping under nets before the distribution. Even in households with at least one net for every two people, over 35% of adults were not sleeping under a net. Malaria No More (MNM) adapted its signature NightWatch communications programme to fit within the coordinated “KO Palu” (Knock Out Malaria) national campaign. This study evaluates the impact of KO Palu NightWatch activities (that is, the subset of KO Palu-branded communications that were funded by MNM’s NightWatch program) on bed net use. Using national survey data collected at baseline (in March/April 2011, before the national LLIN distribution and KO Palu NightWatch launch) and post-intervention (March/April 2012), this study evaluates the impact of exposure to KO Palu NightWatch activities on last-night net use by Cameroonian adults and their children under five. First, a plausible case for causality was established by comparing net use in 2011 and 2012 and measuring exposure to KO Palu NightWatch; next, a propensity score matching (PSM) model was used to estimate the impact of exposure on net use by simulating a randomized control trial; finally, the model was tested for sensitivity to unmeasured factors. The PSM model estimated that among Cameroonians with at least one net in their household, exposure to KO Palu NightWatch activities was associated with a 6.6 percentage point increase in last-night net use among respondents (65.7% vs 59.1%, p < 0.05) and a 12.0 percentage point increase in last-night net use among respondents’ children under five (79.6% vs 67.6%, p < 0.025). Sensitivity analysis suggests only a very small risk of bias from omitted factors influencing exposure and net use. Extrapolating the results of the PSM model to the population of Cameroonians with access to at least one mosquito net, this analysis estimates that approximately 298,000 adults and over 221,000 of their children under five slept under a bed net because of the knowledge, motivation, and/or timely reminder provided by KO Palu NightWatch activities. The programme cost less than $0.16 per adult reached, and less than $1.62 per additional person protected by a net. The results suggest a strong role for mass media communication interventions in support of investments in malaria control commodities such as LLINs.
