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
Bibliographic record
Abstract
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.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
