Malaria is the leading cause of morbidity and mortality in Sudan. The entire population is at risk of contracting malaria to different levels. This study aimed to assess the effectiveness of communication for behavioural impact (COMBI) strategy in enhancing the utilization of long-lasting insecticidal nets (LLINs) among mothers of under-five children in rural areas.
A randomized community trial was conducted in rural area of Kosti locality, White Nile State, Sudan, among mothers of under-five children, from January 2013 to February 2014. A total of 761 mothers from 12 villages were randomly selected, 412 mothers from intervention villages and 349 were from comparison villages.
The knowledge of mothers, in intervention villages, about malaria vector, personal protective measures (PPM) against malaria, and efficacy of LLINs was significantly increased from 86.9 to 97.3 %; 45.9 to 92 % and 77.7 to 96.1 % respectively. Knowledge about usefulness of PPM, types of mosquito nets and efficacy of LLINs was significantly higher in intervention villages compared to comparison villages (p < 0.05), (η = 0.64). Mothers in intervention villages increasingly perceived, post-intervention, that malaria was a serious disease (99.3 %), a preventable disease (98.8 %) and also LLINs as an effective intervention in malaria prevention (92.2 %). This resulted in an increase in the utilization rate of LLINs from 19.2 to 82.8 % in intervention villages compared to comparison villages (p < 0.05) [OR = 4.6, 95 %, CI = (3.72-5.72)], (η = 0.64). The average of mothers' knowledge about malaria was increased by 64 % (η = 0.64), the use of LLINs was increased by 79 % (η = 0.79) and a positive attitude towards malaria was 2.25 times higher in intervention villages than among mothers in the comparison villages.
These results established the usefulness of COMBI strategy for increasing awareness about malaria, developing a positive perception towards malaria prevention and, increasing the utilization of LLINs.
疟疾是苏丹发病和死亡的主要原因。全体人口都有不同程度感染疟疾的风险。本研究旨在评估行为影响沟通(COMBI)策略在提高农村地区五岁以下儿童母亲对长效驱虫蚊帐(LLINs)的使用率方面的有效性。
2013年1月至2014年2月,在苏丹白尼罗河州科斯蒂地区的农村对五岁以下儿童的母亲进行了一项随机社区试验。从12个村庄中随机选取了761名母亲,其中412名来自干预村庄,349名来自对照村庄。
干预村庄中母亲对疟疾病媒、疟疾个人防护措施(PPM)以及长效驱虫蚊帐功效的知晓率分别从86.9%显著提高到97.3%;从45.9%提高到92%;从77.7%提高到96.1%。与对照村庄相比,干预村庄中母亲对PPM的有用性、蚊帐类型以及长效驱虫蚊帐功效的知晓率显著更高(p < 0.05),(η = 0.64)。干预后,干预村庄中的母亲越来越多地认识到疟疾是一种严重疾病(99.3%)、一种可预防疾病(98.8%),并且长效驱虫蚊帐是预防疟疾的有效干预措施(92.2%)。这导致干预村庄中长效驱虫蚊帐的使用率从19.2%提高到82.8%,而对照村庄为(p < 0.05)[OR = 4.6,95%,CI =(3.72 - 5.72)],(η = 0.64)。母亲对疟疾的平均知晓率提高了64%(η = 0.64),长效驱虫蚊帐的使用率提高了79%(η = 0.79),并且干预村庄中母亲对疟疾的积极态度是对照村庄母亲的2.25倍。
这些结果证实了COMBI策略在提高对疟疾的认识、培养对疟疾预防的积极认知以及提高长效驱虫蚊帐使用率方面的有效性。
