背景：2010 年 11 月，塞拉利昂分发了超过 300 万张长效驱虫蚊帐 (LLIN)，目的是为该国所有家庭中的个人提供预防疟疾的保护。方法：我们在大规模分发活动六个月后进行了一项全国代表性调查，以评估其对家庭驱虫蚊帐 (ITN) 拥有和使用的影响。我们利用逻辑回归模型研究了与家庭 ITN 拥有和使用相关的因素。结果：调查包括 4,620 个家庭，在 14 个地区的每个地区的代表性相同。活动结束 6 个月后，87.6% 的家庭拥有至少一份驱虫蚊帐，这比 2008 年最新估计的 37% 增加了 137%。36% 的家庭每两名家庭成员至少拥有一份驱虫蚊帐；农村家庭比城市家庭更有可能为家庭成员提供 >= 1:2 的杀虫剂蚊帐，但社会经济地位或户主教育程度没有差异。在拥有 >= 1 个杀虫剂蚊帐 (ITN) 的家庭中，76.5% 的人在调查前一天晚上穿着杀虫剂蚊帐 (ITN) 睡觉。如果户主听到过疟疾信息，对疟疾传播有正确的了解，并且至少悬挂了一个驱虫蚊帐，则该家庭中的个人更有可能睡在驱蚊蚊帐下。结论：大规模分发活动有效地实现了人口的高覆盖率，特别是在疟疾负担较高的农村家庭中。需要保持这些在公平预防疟疾方面取得的重要成果，才能长期减少疟疾负担。
Background: In November 2010, Sierra Leone distributed over three million long-lasting insecticide-treated nets (LLINs) with the objective of providing protection from malaria to individuals in all households in the country.Methods: We conducted a nationally representative survey six months after the mass distribution campaign to evaluate its impact on household insecticide-treated net (ITN) ownership and use. We examined factors associated with household ITN possession and use with logistic regression models.Results: The survey included 4,620 households with equal representation in each of the 14 districts. Six months after the campaign, 87.6% of households own at least one ITN, which represents an increase of 137% over the most recent estimate of 37% in 2008. Thirty-six percent of households possess at least one ITN per two household members; rural households were more likely than urban households to have >= 1:2 ITN to household members, but there was no difference by socioeconomic status or household head education. Among individuals in households possessing >= 1 ITN, 76.5% slept under an ITN the night preceding the survey. Individuals in households where the household head had heard malaria messaging, had correct knowledge of malaria transmission, and where at least one ITN was hanging, were more likely to have slept under an ITN.Conclusions: The mass distribution campaign was effective at achieving high coverage levels across the population, notably so among rural households where the malaria burden is higher. These important gains in equitable access to malaria prevention will need to be maintained to produce long-term reductions in the malaria burden.
