Odds ratio is obtained from binary logistic regression coeffic, with backward elimination procedure.

Total number of the participants that remained in a final model was 120.

Factors included in the model were: Age in years, education, religion, number of children, first place of checked up, if IEC was seen in commune, reasons of taking iron tablets, if caution for taking iron tablets was told, if iron tablets were delivered before pregnancy, place of iron tablets supplied, knowing that role of iron is good for health, if side effects was explained were also entered in the first models and did not remain in the final models. Only risk factors which partial regression coefficients that were significant (p < 0.05) were included in the final models.
