Sociodemographic factors associated with the use of insecticide treated nets among under-fives in Nigeria: Evidence from a national survey.

Insecticide treated nets (ITN) are effective in malaria prevention; however, they remain underutilized among children. A secondary analysis of the 2018 Nigeria-Demographic and Health Survey including logistic regression was conducted to determine factors influencing ITN use among under-fives (U5s). Overall, 22,954 (72.4%) slept under ITN the night before the survey. Children <4 years and those in the northern regions had significantly higher odds of using ITN, as did those from households with ≤6 members and those from the lowest to middle wealth quintiles. However, among those households recorded as having "universal ITN coverage" i.e. at least one net between two persons, children <3 years, those from the rural northern regions and those from the lowest wealth category had significantly higher odds of using ITN. Interventions to improve ITN use by U5s should be intensified among households with larger size, those from the highest wealth quintiles and residents in southern Nigeria.
