Trend and determinants of anemia change among pregnant and/or lactating women in Ethiopia: A multivariate decomposition analysis

BACKGROUND: Even though anemia was highly targeted in different global strategies, many pregnant and/or lactating women and children were suffering from it and its complications. Besides this, prior trend analysis has not been conducted among pregnant and/or lactating women in Ethiopia. Therefore, this study aimed to assess the trend and determinants of anemia change among pregnant and/or lactating women in Ethiopia. METHODS: The study utilized two consecutive Ethiopia Demographic and Health Survey (EDHS) datasets. A total of 6,106 and 5,641 pregnant and/or lactating women in 2011 and 2016 survey respectively were included in the analysis. The data were analyzed by using Stata version 14.0. Logit based decomposition analysis was done to identify contributing factors for anemia change and statistical significance was determined by using P-value. RESULTS: The trend of anemia was increased from 19% in 2011 to 29% in 2016 EDHS. The analysis revealed that, 8% of the overall change in anemia was because of the change in women's composition. Changes in the composition of pregnant and/or lactating women according to region, economic status and tobacco and/or cigarette use were the major sources of the change. Greater than 90% of the increase in anemia was due to differences in the coefficient. Mostly, the change in behaviors of the Amhara population, those who had a history of terminated pregnancy and use tobacco and/or cigarette were the sources of the change. CONCLUSIONS: Anemia among pregnant and/or lactating women was increased against government interventions over the last half-decade in Ethiopia. Programmatic interventions targeting Somali and Dire Dawa regions are still needed to decrease anemia.
