Exploring the gap between coverage, access, and utilization of long-lasting insecticide-treated nets (LLINs) among the households of malaria endemic districts in Bangladesh.

backgroundMalaria is still a major public health concern in Bangladesh in spite of mass distribution of long-lasting insecticide-treated nets (LLINs) as a key preventive strategy. There might be a considerable gap between coverage and actual use of nets by the population in endemic areas. This study intended to assess the gap between coverage, access to and use of LLINs among the households in malaria-endemic settings in Bangladesh.

methodsThis cross-sectional study collected data from 2640 households of 13 endemic districts of Bangladesh through three-stage cluster random sampling. The gap between coverage, access and use of LLINs were calculated using the procedure established by the Roll Back Malaria Monitoring and Evaluation Reference Group. To support the quantitative findings, qualitative data were also collected through in-depth interview, focus group discussion and key informant interview and analysed accordingly.

resultsOf 2640 total households, 77.4% (n = 2044) possessed at least two LLINs, 56.8% (n = 1499) had insufficient access, and 18.8% (n = 495) had excess LLINs. Members of 77.9% (n = 2056) households had used LLINs the previous night and 6.0% (n = 68) did not use LLINs despite having sufficient access. LLIN use was lower in non-hill track areas, in Bengali community, in richer households and households with more than four members. Moreover, qualitative findings revealed that the major reasons behind not using LLINs were insufficient access, sleeping outside the home, migration, perceived low efficacy of LLINs, or fear of physical side effects.

conclusionClosing the access gap by providing enough nets through solid investment and well-designed behavioural change interventions are crucial for achieving and sustaining universal coverage.
