扩大疟疾控制范围以实现全民覆盖需要更好地了解受保护最少并为中断传播提供障碍的人口亚群体。在这里，我们研究了非洲使用经杀虫剂处理的蚊帐（ITN）的年龄模式与生物脆弱性的关系以及对未来普遍覆盖前景的影响。汇总了非洲 18 个疟疾流行国家最近的国家家庭调查数据，以确定按年龄和性别划分的驱虫蚊帐使用信息。最早和最近一次全国调查中点年份的年龄结构中变预测人口估计值是根据驱虫蚊帐保护的年龄计算人口。所有调查均在 2005 年至 2009 年期间进行，要么是人口健康调查（n = 12），要么是疟疾指标调查（n = 6）。各国被分为三个驱虫蚊帐使用组： <10%；<10%； 10 至 <20%；计算了 2007 年中点的 ≥20% 和预计人口估计数。总体而言，不同国家和三个国家组的驱虫蚊帐总体使用情况与年龄相似，驱蚊蚊帐使用率最初在 5 岁以下儿童中较高，在 5-19 岁人群中急剧下降，然后在 20-44 岁年龄段再次上升，最后在老年群体中逐渐下降。对于所有国家组而言，未受杀虫剂蚊帐保护的人口比例最高 (38% - 42%) 是 5 岁至 19 岁的人口。在疟疾流行的非洲，学龄儿童受到杀虫剂蚊帐的保护最少，但却是最大的感染库。随着学校入学率的提高，应将向学校提供杀虫剂蚊帐视为实现杀虫剂蚊帐普遍覆盖并提高影响寄生虫传播的可能性的一种方法。
The scaling of malaria control to achieve universal coverage requires a better understanding of the population sub-groups that are least protected and provide barriers to interrupted transmission. Here we examine the age pattern of use of insecticide treated nets (ITNs) in Africa in relation to biological vulnerabilities and the implications for future prospects for universal coverage. Recent national household survey data for 18 malaria endemic countries in Africa were assembled to indentify information on use of ITNs by age and sex. Age-structured medium variant projected population estimates for the mid-point year of the earliest and most recent national surveys were derived to compute the population by age protected by ITNs. All surveys were undertaken between 2005 and 2009, either as demographic health surveys (n = 12) or malaria indicator surveys (n = 6). Countries were categorized into three ITN use groups: <10%; 10 to <20%; and ≥20% and projected population estimates for the mid-point year of 2007 were computed. In general, the pattern of overall ITNs use with age was similar by country and across the three country groups with ITNs use initially high among children <5 years of age, sharply declining among the population aged 5-19 years, before rising again across the ages 20-44 years and finally decreasing gradually in older ages. For all groups of countries, the highest proportion of the population not protected by ITNs (38% - 42%) was among those aged 5-19 years. In malaria-endemic Africa, school-aged children are the least protected with ITNs but represent the greatest reservoir of infections. With increasing school enrollment rates, school-delivery of ITNs should be considered as an approach to reach universal ITNs coverage and improve the likelihood of impacting upon parasite transmission.
