Library ANC.IND.2
WHO Antenatal Care (ANC) Indicator 2
Percentage of pregnant women who received iron and folic acid (IFA) supplements for 90+ days

Numerator: Number of pregnant women who received the recommended number of IFA tablets during all previous contacts
Numerator Computation: COUNT of number of women who were prescribed IFA tablets at each ANC contact they have had
Denominator: Total number of antenatal clients with a first contact
Denominator Computation: COUNT of all women whose records were closed (ANC
  close form) in the last reporting period due to any of the reasons below:
    » live birth
    » stillbirth
    » miscarriage
    » abortion
    » woman died
    » lost to follow-up
    » moved away
