Abstract

Background: Iron folic acid supplementation during pregnancy is one of the major intervention given for pregnant women to alleviate the risk of anemia. According to WHO 2012 report anemia prevalence among pregnant women is highest in Africa including Ethiopia. The major problem with increased prevalence of anemia during pregnancy is noncompliance as the women fails to take their pills properly. Objective: Aimed to validate self report to measure adherence to iron folic acid supplementation among ante-natal care attending pregnant women in Addis Ababa Ethiopia. Methods: Longitudinal was employed among 361 pregnant women in Addis Ababa from March to July 2019. A multi-stage random sampling procedure was employed. The study participants was prospectively observed over three months using pill count and self report methods. Data were entered using Epi-Info version 7 and analyzed using STATA SE Version 14.1. Estimation of the prevalence of adherence was done using both methods. Sensitivity, specificity and positive predictive value was computed to check the validity on the performance of self report in estimating Adherence. McNemar test was done to assess if there was significant difference in adherence rate between the methods. P-value of <0.05 was considered to indicate a significant difference in prevalence. Result: The prevalence of iron folic acid supplementation of 82.8% (at 95% CI, 78.5 – 86.6) was obtained by self report where as adherence rate of 58.2% (95% CI of 52.9 - 63.3) was observed using pill count method. Descripance of 24.6 % difference was observed between both methods of adherence measurement. The sensitivity, specificity and RUC curve of selfreport was showed 97.7%, 37.7% and 0.68% respectively at a P-Vvalue of < 0.05. Conclusion: Valid measurment is extremely important in assessing adherence rate. Self report adherence estimation to IFA supplementation continues to be problematic and difficult in determining how pregnant women are using their supplement. Self-report adherence measurement had poor validity in measuring those who were correctly adhered as compared to pill count. There was a statistically significant difference in estimation of adherence between the self report and pill count methods.
