Indoor residual spraying (IRS) is among the major vector control strategies recommended for endemic populations by the World Health Organization (WHO). The success of IRS requires high coverage which is dependent on its acceptability. In Nigeria, IRS pilots have been ongoing and rejection has been a major setback to its coverage. We assessed coverage of IRS and determined factors associated with its acceptability in Nasarawa Eggon district, Nasarawa state, Nigeria.
A cross-sectional survey involving 409 households selected using multi-stage sampling was carried out. Trained data collectors administered pre-tested structured questionnaire to collect data on socio-demographic characteristics of household heads or their representatives, their perceptions on IRS and factors associated with IRS acceptability. Descriptive, bivariate and multivariate analyses were done at 5% level of significance.
Majority of respondents were male (79.7%) and married (82.6%), and their mean age was 36.4 ± 13.3 years. Coverage of IRS was 99.3%. However, only 82.6% of those who previously accepted IRS were willing to accept it in again. Factors independently associated with acceptability were perceived effectiveness of IRS (aOR = 21.8; 95%CI = 6.9-68.8) and lower household cost of malaria prevention after IRS (aOR = 5.0; 95%CI = 1.1-21.8).
IRS coverage in the communities studied met WHO minimum standard of 85%. However, for similar results to be achieved in future, acceptability must be promoted by providing information on its effectiveness and its ability to reduce household cost of malaria prevention.
室内滞留喷洒（IRS）是世界卫生组织（WHO）推荐给流行地区人群的主要病媒控制策略之一。IRS的成功需要高覆盖率，而这取决于其可接受性。在尼日利亚，IRS试点一直在进行，但拒绝接受是其覆盖率的一个主要挫折。我们评估了尼日利亚纳萨拉瓦州纳萨拉瓦埃贡区IRS的覆盖率，并确定了与其可接受性相关的因素。
采用多阶段抽样选取409户家庭进行横断面调查。经过培训的数据收集员使用预先测试的结构化问卷收集关于户主或其代表的社会人口特征、他们对IRS的看法以及与IRS可接受性相关的因素的数据。在5%的显著性水平上进行描述性、双变量和多变量分析。
大多数受访者为男性（79.7%）且已婚（82.6%），他们的平均年龄为36.4±13.3岁。IRS的覆盖率为99.3%。然而，之前接受IRS的人中只有82.6%愿意再次接受。与可接受性独立相关的因素是对IRS有效性的认知（调整后比值比[aOR]=21.8；95%置信区间[CI]=6.9-68.8）以及IRS后家庭预防疟疾成本较低（aOR=5.0；95%CI=1.1-21.8）。
在所研究的社区中，IRS覆盖率达到了WHO规定的85%的最低标准。然而，为了在未来取得类似的结果，必须通过提供有关其有效性以及降低家庭预防疟疾成本能力的信息来提高可接受性。
