Identifying risk factors of anemia among women of reproductive age in Rwanda to inform designing better interventions – a secondary data analysis, cross-sectional study using the Rwanda Demographic and Health Survey (RDHS) data
Abstract Background Anemia among Women of Reproductive Age (WRA) continues to be among the major public health problems in many developing countries including Rwanda where it was increased comparing 2015 to 2010 Rwanda Demographic and Health Survey (RDHS) reports. A thorough understanding of the its risk factors is necessary to design interventions. However, to the best of our knowledge, no study with national representation assessing anemia risk factors among WRA has been conducted in Rwanda. Therefore, this study aims to identify anemia risk factors among WRA in Rwanda. Methods This was a quantitative, cross-sectional study using secondary data from the 2014-2015 RDHS data. The study population consisted of 6680 WRA who were tested for anemia during the survey. Anemia was defined as having a hemoglobin level equal or below to 10.9 g/dl for a pregnant woman, and hemoglobin level equal or below to 11.9 g/dl for a non-pregnant woman. Pearson’s chi-squared test and multiple logistic regression were conducted for bivariate and multivariable analysis respectively. We reported Odds Ratio (OR), 95% Confidence Intervals (CI) and p-values. Results The overall prevalence of anemia among WRA was 19.2% (95% CI: 18.0 - 20.5). After controlling for other variables, four factors were found associated with lower odds of anemia, they are being obese (OR: 0.61, 95% CI: 0.40 - 0.91), being in rich category (OR: 0.74, 95% CI: 0.63 - 0.87), sleeping under a mosquito net (OR: 0.85, 95% CI: 0.74 - 0.98), and using hormonal contraceptives (OR: 0.61, 95% CI: 0.50 - 0.73). Four factors associated with higher odds of anemia were being underweight (OR: 1.39, 95% CI: 1.09 - 1.78), using an Intra Uterus Device (OR: 1.98, 95% CI: 1.05 - 3.75), and living in the Southern province (OR: 1.45, 95% CI: 1.11 - 1.89) or in the Eastern province (OR: 1.41, 95% CI: 1.06 - 1.88). Conclusion Anemia continues to pose public health challenges; novel public health interventions should consider geographic variations, improve women economic status, and strengthen iron supplementation especially for Intrauterine Device users. Additionally, given the association between anemia and malaria, interventions to prevent malaria should be enhanced.
