BackgroundLinear growth faltering continues to be a pervasive public health concern, considering its persistent prevalence and repercussions. This study aimed to investigate potential maternal factors promoting normal linear growth among children from impoverished Rwandan households.MethodsA structured questionnaire was used to collect data from 807 mother-child dyads selected using a multi-stage cluster sampling procedure. The main outcome variable was height-for-age Z-scores. The main predictors were the mother has income-generating activity, maternal education, maternal depression, household decision-making (HHDM), number of ANC visits, use of family planning method, family planning types, and mode of delivery. The potential confounding variables were child age, both parents working, good handwashing practice, owning a vegetable garden, and the total number of livestock. Univariate analysis was used to establish means, frequencies, and percentages; the Kruskal-Wallis, Mann-Whitney U, and Spearman Rank Correlation tests were used for bivariate analysis and robust linear regression for multivariable analysis.ResultsMaternal factors promoting normal linear growth of children were the presence of the mother’s income-generating activity (ꞵ=0.640 [0.0269−1.253], p-value=0.041), mother’s involvement in household decision-making (ꞵ=0.147 [0.080− 0.214], p-value<0.001), and higher frequency of ANC consultations (ꞵ=0.189 [0.025− 0.354], p-value=0.024). Additionally, a combination of household decision-making with ANC visit numbers predicted an increase in child linear growth (ꞵ=0.032 [0.019− 0.045], p-value<0.001).ConclusionMaternal factors such as maternal income-generating activity, maternal involvement in household decision-making, and increased number of ANC visits were found to promote normal child linear growth and can provide valuable information for shaping interventions and policies aimed at promoting child growth in the Rwandan community.
