Spatial distribution and determinant factors of anemia among women age 15-49 years in Burkina Faso; using mixed-effects ordinal logistic regression model.

Background: Anemia is a condition in which the number of healthy red blood cells/ hemoglobin (Hgb) level (and consequently their oxygen-carrying capacity) is insufficient to meet the body's physiologic needs. Thus, the current study is aimed to assess the spatial distribution and determinant factors of anemia among women aged 15-49 in Burkina Faso.

Methods: A secondary data analysis was done based on 2021 Burkina Faso; Demographic and Health Surveys. Total weighted samples of 5655 women's were included. Data processing and analysis were performed using STATA 14; ArcGIS 10.1 and SaTScan 9.6 software.

Result: The spatial distribution of anemia in Burkina Faso among women aged 15-49.was found to be clustered (Global Moran's I = 0.25, p value < 0.0001). In the multivariable mixed-effect ordinal regression analysis; Age 25-29 years [AOR = 1.31 ; 95% CI: 1.06 1.61], rich wealth status [AOR = 1.32 ; 95% CI: 1.08 1.62], regions Cascades [AOR = 1.62 ; 95% CI: 1.16 2.25],Hauts-bassis [AOR = 1.40; 95% CI: 1.06 1.84], Plateau central [AOR = 0.72 ; 95% CI: -0.54 0.96 and Sahel[AOR = 0.42 ; 95% CI: 0.28 0.63], were significant predictors of anemia among women aged 15-49.

Conclusions: A significant clustering of anemia among women aged 15-49 were found in Burkina Faso. Age, wealth index, regions Cascades, Hauts-bassins, Plateau central, and Sahel were significant predictors of anemia.
