使用经杀虫剂处理的蚊帐被广泛认为是预防疟疾的主要干预措施之一，高使用率是疟疾项目的中心目标。家庭拥有至少一个驱虫蚊帐与人口使用驱虫蚊帐之间的差距过去被视为未能实现适当蚊帐使用的证据。然而，过去的研究将蚊帐使用与至少拥有一顶蚊帐进行了比较，而不是将家庭内获得足够蚊帐的情况进行了比较。这项研究使用“击退疟疾”组织和世界卫生组织目前建议的“家庭内获得蚊帐的机会”的比较指标，重新计算了最近大型家庭调查中蚊帐使用的差距。使用了撒哈拉以南非洲41次人口健康调查和疟疾指标调查（2005-2012年）的数据。对于每个数据集，计算了三个指标：使用驱虫蚊帐的人口、使用驱虫蚊帐的人口和至少拥有一个驱虫蚊帐的家庭。驱虫蚊帐使用差距表示为1与使用与获得比率之间的差距。使用者与有机会使用者的比例中位数很高，为82.1%。即使在人口获得率低于50%的情况下，只要能够获得，使用驱虫蚊帐的人口比例中位数也为80.6%，而在获得率高于50%的情况下，这一比例上升到91.2%。使用与获得的线性回归显示，89.0%获得蚊帐的家庭成员在前一天晚上使用蚊帐。这些结果清楚地表明，以前将净使用差距解释为行为改变沟通干预措施的失败是不合理的，相反，差距主要是由于缺乏家庭内部的访问。它们还表明了新建议的驱虫蚊帐指标的有用性;在家庭中获得驱虫蚊帐的情况比拥有驱虫蚊帐的情况更能准确地比较驱虫蚊帐的使用情况。
Use of insecticide treated nets is widely recognized as one of the main interventions to prevent malaria and high use rates are a central goal of malaria programs. The gap between household ownership of at least one ITN and population use of ITN has in the past been seen as evidence for failure to achieve appropriate net use. However, past studies compared net use with ownership of at least one net, not access to sufficient nets within households. This study recalculates the net use gap in recent large household surveys using the comparison indicator of ‘access to nets within the household’ as now recommended by Roll Back Malaria and the World Health Organization. Data from 41 Demographic Health Surveys (DHS) and Malaria Indicator Surveys (MIS) (2005–2012) in sub-Saharan Africa were used. For each dataset three indicators were calculated: population access to ITN, population use of ITN, and household ownership of at least one ITN. The ITN use gap was expressed as the difference between one and the ratio of use to access. The median proportion of users compared to those with access was high, at 82.1%. Even at population access levels below 50%, a median 80.6% used an ITN given they had access, and this rate increased to 91.2% for access rates above 50%. Linear regression of use against access showed that 89.0% of household members with access to nets used them the night before. These results clearly show that previous interpretations of the net use gap as a failure of behavioral change communication interventions were not justified and that the gap was instead primarily driven by lack of intra-household access. They also demonstrate the usefulness of the newly recommended ITN indicators; access to an ITN within the household provides a much more accurate comparison of ITN use than ownership.
