Insecticide-treated mosquito nets are effective in reducing malaria transmission and mortality, yet they are underused for prevention. In this study, 561 households in 33 clusters were surveyed to estimate the coverage of net ownership and the frequency of use according to selected characteristics. Of the 540 participating household heads, 247 (46%) owned mosquito nets. Of 1681 individuals in households with mosquito nets, 1359 (81%) used the nets. A household monthly income > or =2000 Indian rupees (US$45) was strongly associated with mosquito net ownership (prevalence ratio=12, 95% CI 7.8-82). Factors independently associated with net use in multivariate analysis included age < 35 years (P<0.001), sleeping inside (P<0.001), use of repellent (P=0.03) as well as knowledge that mosquitoes cause malaria (P=0.002) and that malaria is severe in children (P<0.001). Whilst household income is the strongest determinant of mosquito net ownership, selected knowledge elements are associated with net use. It is necessary to improve financial accessibility to nets and to communicate that malaria is a disease transmitted by mosquitoes that could be fatal in children.
经杀虫剂处理的蚊帐可有效减少疟疾传播和死亡率，但预防疟疾的使用率仍然较低。在这项研究中，对 33 个群组中的 561 户家庭进行了调查，以根据选定的特征估计蚊帐拥有率和使用频率。在 540 名参与的户主中，有 247 人（46%）拥有蚊帐。在有蚊帐的 1681 名家庭中，有 1359 人（81%）使用了蚊帐。家庭月收入≥2000 印度卢比（45 美元）与拥有蚊帐有很强的相关性（患病率比=12，95%置信区间 7.8-82）。多变量分析中与蚊帐使用相关的因素包括年龄<35 岁（P<0.001）、在室内睡觉（P<0.001）、使用驱虫剂（P=0.03）以及对蚊子引起疟疾（P=0.002）和疟疾在儿童中严重（P<0.001）的认识。虽然家庭收入是拥有蚊帐的最强决定因素，但某些知识要素与蚊帐使用有关。有必要提高获得蚊帐的经济可及性，并传播疟疾是一种由蚊子传播的疾病，在儿童中可能致命的信息。
