ABSTRACT
Introduction. The use of insecticide-treated mosquito nets (ITNs) is a key intervention in malaria control efforts. However, non-utilization of ITNs continues to be a challenge in many endemic regions, including Benin. The aim of our study was to determine the factors associated with the non-use of ITNs in Benin in 2022. Methodology. This study utilized secondary data from the malaria indicators survey conducted in Benin in 2022. A total of 9,184 households and 44,669 individuals were included in the analysis. The dependent variable was the non-use of ITNs, while independent variables included age, residential area, etc…. Descriptive statistics and binary logistic regression were used for data analysis. Results. A total of 9184 households were included in the study. The median age of household members was 17 years. The age group of 30-64 years was the most represented with a sex ratio of 1, 06. Household heads were predominantly of Fon ethnicity in 33% of cases, had a primary educational level in 22.7% of cases, and belonged to the middle socioeconomic status quintile in 20.8% of cases. The prevalence of non-use ITNs was 39.4%. Men slept under ITNs less than women (p < 2.2 × 10−16). Individuals with a primary education had a 16% lower risk of not using ITNs (aOR = 0.86; 95% CI = [0.79-0.87]) compared to those with no education. This risk was 49% lower when the household head had a secondary school (aOR = 0.51; 95% CI = [0.45-0.55]) or university education (aOR = 0. 51; 95% CI = [0.45-0.57]). Conclusion. Understanding and addressing the multifaceted determinants of ITN non-use are essential for improving malaria control strategies and reducing the disease burden in endemic regions like Benin.
RÉSUMÉ
Introduction. L'utilisation de moustiquaires imprégnées d'insecticide (MIIs) est une intervention clé dans les efforts de lutte contre le paludisme. Cependant, la non-utilisation des MIIs continue d'être un défi dans de nombreuses régions endémiques, dont le Bénin. L'objectif de notre étude était de déterminer les facteurs associés à la non-utilisation des MIIs au Bénin en 2022. Méthodologie. Cette étude a utilisé des données secondaires de l'enquête sur les indicateurs du paludisme menée au Bénin en 2022. Un total de 9 184 ménages et 44 669 sujets ont été inclus dans l'analyse. La variable dépendante était la non-utilisation des MIIs, tandis que les variables indépendantes incluaient l'âge, la zone de résidence, etc.... Des statistiques descriptives et une régression logistique binaire ont été utilisées pour l'analyse des données. Résultats. Un total de 9184 ménages ont été inclus dans l'étude. L'âge médian des membres du ménage était de 17 ans. Le groupe d'âge de 30 à 64 ans était le plus représenté avec un ratio hommes/femmes de 1,06. Les chefs de ménage étaient majoritairement d'ethnie Fon dans 33% des cas, avaient un niveau d'éducation primaire dans 22,7% des cas, et appartenaient au quintile de statut socio-économique moyen dans 20,8% des cas. La prévalence de la non-utilisation des MIIs était de 39,4%. Les hommes dormaient sous des MIIs moins que les femmes (p < 2,2 x 10−16). Les individus ayant un niveau d'éducation primaire avaient un risque de non-utilisation des MIIs 16% inférieur (aOR = 0,86 ; IC 95% = [0,79-0,87]) par rapport à ceux sans éducation. Ce risque était de 49% inférieur lorsque le chef de ménage avait un niveau d'éducation secondaire (aOR = 0,51 ; IC 95% = [0,45-0,55]) ou universitaire (aOR = 0,51 ; IC 95% = [0,45-0,57]). Conclusion. Comprendre et aborder les déterminants multifacettes de la non-utilisation des MIIs sont essentiels pour améliorer les stratégies de lutte contre le paludisme et réduire le fardeau de la maladie dans les régions endémiques comme le Bénin.
