Results: In our study, prevalence of IDA in study participants was 18.6%. Nearly half of anemic patients had moderate anemia, which is higher than the World Health Organization (WHO) median prevalence rate of 32.6 percent. Conclusions: The majority of cases of anemia are this research, socioeconomic determinants. Therefore, in women attending for delivery at term, they should be considered as major risk factors of anemia.
