Ownership and use of insecticide-treated nets under Ghana's National Malaria Control Program: What are the correlates?

Objectives Ghana's National Malaria Control Program distributes free insecticide-treated nets (ITNs) as a malaria control measure. Some households with the ITN do not use it, however. This paper explores the socioeconomic and demographic determinants of ITN ownership and use among Ghanaian families. Methods Data on 5741 households were obtained from the 2019 Ghana Malaria Indicator Survey. The survey is a nationally representative survey that obtains data on malaria-related issues. Negative binomial and Tobit regressions were applied to achieve the study's objectives. Results Residence (rural-urban), wealth, and administrative region emerged as the most important predictors of ITN ownership and usage in Ghana. The results favoured rural and non-Greater Accra residents. However, wealth had a contrasting association with ITN ownership and use. Whereas affluent households owned more ITNs than the extremely poor, the latter used them more. Also, age and household size were significant for ITN ownership. Both variables had a nonlinear (inverted U-shaped) relationship with ITN ownership. In contrast, the proportion of household members under 5 and the bed net-to-household size ratio were positive and statistically significant determinants of ITN use. Conclusion The study highlights the need to effectively target the poor, especially in rural areas, for ITNs under the NMCP instead of universal distribution.
