BackgroundMalaria is the main cause of morbidity and mortality in Cameroon. Insecticide-treated nets (ITNs) significantly reduce malaria transmission, but their use is not common among populations. This study aimed to estimate the prevalence of the non-use of ITNs and identify its major determinants.Methods A cross-sectional study was conducted on interview data collected in households selected across all the regions of Cameroon through a non-probabilistic, random, 2-stage stratified sampling process. Descriptive statistics were used to describe the distribution of baseline characteristics across the households, and statistical tests assessed if the distribution of these characteristics differed significantly based on the non-use of ITNs, with 0.05 serving as a threshold of the p-value for statistical significance. The prevalence of the non-use of ITNs was estimated, and logistic regression models were used to tally the odds ratios of the associations between various factors and the non-use of ITNs, along with their 95% confidence intervals. Sensitivity, specificity, and areas under the curves were also determined, and the Hosmer Lemeshow test was used to measure the goodness of fit of each statistical model. Results Of the 7593 households interviewed, 77% had at least one ITN and 59% of the population used ITNs. Only 72% of the population with at least one ITN actually used it. The logistic model of the Multivariate analysis was significant at 5%. The area under the receiver operating characteristic (ROC) curve was 0.7087 and the error rate was 18.01%. The sensitivity and specificity of the model were 97.56% and 13.70% respectively. The factors that were associated with ITN use were the presence of sufficient nets in the household ( p <0.0001), the region of residence (p< 0.0001), the level of education of the respondent (p < 0.0001) and the standard of living (p=0.0286). Sex, age, colour preferences, as well as the shape and size of the net were not associated with ITN use.ConclusionsThe use of ITNs was low and varied according to specific factors. These identified factors could be used as the foundations of effective sensitization campaigns on the importance of ITNs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
