Predictors of prenatal iron folic acid supplement utilization in Wolaita, South Ethiopia: a community based cross-sectional study (quantitative and qualitative approach)

Background Effectiveness of prenatal iron supplementation program depends on utilization of the supplement by pregnant women. Nevertheless, in Ethiopia, regardless of increasing efforts, lower proportion of pregnant women use the supplementation for recommended 3 months and above but, the reason is not clear. This study aimed to identify the level and factors associated with utilization of prenatal iron supplementation. Methods A community based cross-sectional quantitative study complemented with qualitative component was carried out in January, 2016. A total of 411 pregnant women who gave birth 6 months preceding data collection were selected using multi-stage cluster sampling technique. Qualitative data were collected by conducting four focus group discussions (FGDs) of local pregnant mothers and interviewing district maternal and child health (MCH) focal, 3MCH heads of health centers and four health extension workers. Factors associated with appropriate utilization of supplementation were assessed using multivariate logistic regression. The outputs of analyses were presented using Adjusted Odds Ratio (AOR) with 95% confidence intervals (CI). Result From the study participants, 11.5% (95% CI = 9.9–13.1%) took the supplement for the recommended duration of 3 months or above. Pregnant women who could not read and write had 77% reduced odds of using iron supplementation than their counterparts (AOR = 0.23(95% CI: 0.07–0.75)). As compared to women who had four or more antenatal care (ANC), women with 2 and 3 ANC visits had 78% (AOR = 0.22(0.07–0.63)) and 66% (AOR = 0.34(0.14–0.81)) reduced odds of using the supplementation, respectively. As compared to women who were aware of benefits of taking the supplement for maternal and child health, the counterparts had 90% (AOR = 0.10 (0.10–0.63)) reduced odds of using the supplement. Women who were not knowledgeable of anemia had 85% (AOR = 0.15(0.04–0.62) reduced odds of using the supplement than those who were knowledgeable. The qualitative study indicated that there was no problem in the supply and logistic system of iron supplement and leading reasons for not taking the supplement were late initiation of Antenatal Care, lack of awareness and occurrence of side effects; unpleasant taste, nausea, vomiting. Conclusion In the study area utilization of prenatal iron supplementation is very low. Improving maternal education, ensuring early and frequent ANC, educating pregnant women about the benefits of service and ensuring comprehensive knowledge of anemia expected to improve the utilization of prenatal iron supplementation.
