BACKGROUND & OBJECTIVES: Malaria presents a huge health and economic burden to families living in malaria endemic areas. The use of insecticide-treated nets (ITNs) is one of the global strategies in decreasing the malaria burden on vulnerable populations. The use of ITNs reduces clinical malaria by over 50% and all cause mortality in children by 15-30% when the overall population coverage is >70%. This study was aimed at establishing the level of household insecticide -treated bednet ownership and utilization in Rivers State, Nigeria before a statewide scale -up distribution campaign.
A descriptive, cross - sectional study was carried out in the Rivers State in November 2008 among household heads or their proxies to serve as a pre -intervention baseline for the scale -up distribution of insecticide treated bednets in the state. The households were selected by a multi -staged sampling technique: first stage being the selection of Local Government Areas (LGAs) from Senatorial districts, second stage the selection of communities from LGAs and final stage the selection of households. Data were collected using a questionnaire adapted from the WHO/FMoH and analyzed using the Epi -Info version 6.04d statistical software package. Hypothesis tests were conducted to compare summary statistics at 95% significance level.
A total of 811 household heads or their proxies were interviewed. Their age ranged between 20 and 70 yr, with a mean of 47.96 ± 4.39 yr. The study showed that although 552 (68.1%) of the households owned bednets, only 245 (30.2%, 95% CI=27.1-33.5) of them owned long -lasting insecticidal nets (LLINs). Similarly, only 37.2% of those who owned ITNs slept under them the night preceding the survey.
Household ITN ownership and utilization were low in the state. Incorporating behavour change communication package as part of the ITN distribution intervention is advocated to increase ITNs utilization in the state.
疟疾给生活在疟疾流行地区的家庭带来了巨大的健康和经济负担。使用经杀虫剂处理的蚊帐(ITN)是减轻弱势群体疟疾负担的全球战略之一。当总体人群覆盖率>70%时,使用ITN可使临床疟疾减少50%以上,儿童全死因死亡率降低15 - 30%。本研究旨在在尼日利亚河流州开展全州范围的扩大分发运动之前,确定家庭经杀虫剂处理蚊帐的拥有率和使用率。
2008年11月在河流州对户主或其代理人进行了一项描述性横断面研究,作为该州扩大分发经杀虫剂处理蚊帐的干预前基线。采用多阶段抽样技术选择家庭:第一阶段从参议院选区中选择地方政府区域(LGA),第二阶段从LGA中选择社区,最后阶段选择家庭。使用从世界卫生组织/尼日利亚联邦卫生部改编的问卷收集数据,并使用Epi - Info 6.04d版统计软件包进行分析。进行假设检验以在95%显著性水平下比较汇总统计数据。
共采访了811名户主或其代理人。他们的年龄在20至70岁之间,平均年龄为47.96 ± 4.39岁。研究表明,虽然552户(68.1%)家庭拥有蚊帐,但其中只有245户(30.2%,95%可信区间=27.1 - 33.5)拥有长效杀虫剂蚊帐(LLIN)。同样,在拥有ITN的人群中,只有37.2%的人在调查前一晚睡在蚊帐下。
该州家庭ITN的拥有率和使用率较低。建议将行为改变沟通方案纳入ITN分发干预措施,以提高该州ITN的使用率。
