Abstract:
Objective To analyze the situation of insecticide-treated nets (ITNs) ownership in malaria-endemic African countries from 2010 to 2023, so as to provide insights into China’s deeper participation in malaria control in Africa. Methods The study period from 2010 to 2023 was divided into three phases: the baseline phase (from 2010 to 2015), the middle phase (from 2016 to 2019), and the final phase (from 2020 to 2023), a total of 11 African countries with at least one Demographic and Health Survey (DHS) in each phase were included. Data pertaining to ITNs in 33 surveys of the above 11 African counties from 2010 to 2023 were captured from the DHS database, and the proportions of sources of ITNs and ITN ownership in each phase (number of ITNs ownership per person, overall ownership rate, and ownership rate per two residents) were calculated. The differences in numbers of ITNs per person between urban and rural areas and specified by socioeconomic status were analyzed. Results The proportions of ITNs from distribution campaigns were 60.24% to 94.01% and 50.46% to 85.04% in 11 African countries in the middle and final phases, respectively. The median numbers (interquartile range) of INTs ownership per person were 0.22 (0.50), 0.33 (0.50) and 0.33 (0.50) in the baseline, middle, and final phases, and the overall ownership rates [95% confidence interval (CI)] were 59.77% (59.50%, 60.05%), 70.32% (70.06%, 70.57%), and 69.21% (68.95%, 69.47%), while the ownership rates per two residents were 26.91% (26.66%, 27.16%), 38.07% (37.80%, 38.34%), and 36.56% (36.29%, 36.84%), respectively. The number of ITNs per person showed a significant increase followed by a significant decrease in 7 countries during all three phases (H = 102.518 to 2 327.440, all P < 0.05; Z = -48.886 to -4.653, all P < 0.016 7 after Bonferroni correction). In 33 surveys, there were 31 (Z = -26.719 to -2.472, P < 0.05) and 28 surveys (Z = -27.316 to -4.068, P < 0.001) with significant differences in numbers of ITNs ownership per person between households in urban and rural areas and with different socioeconomic status, including 20 surveys with a significantly higher number of ITNs ownership per person in households in rural areas than in urban areas, and 17 surveys with a significantly higher number of ITNs ownership per person among the poorest households than among the richest households. Conclusions There are substantial disparities in ITNs ownership in 11 African countries. Intensified co-operation on malaria prevention and control measures, such as ITNs, is recommended between China and African countries to build a global community of health for all.
