Library ANC.IND.7
WHO Antenatal Care (ANC) Indicator 7
Percentage of pregnant women with at least one blood pressure measure during ANC

Numerator: Number of antenatal clients with blood pressure measured
Numerator Computation: COUNT of all women who had their blood pressure measured at least once during pregnancy
Denominator: Total number of pregnant women 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

Disaggregation:
Age (10-14, 15-19, 20+)
Education Level (none, don't know, primary, secondary, higher)
Trimester categories: 1st (GA ≤ 12 weeks); 2nd (GA > 12 weeks to ≤ 28 weeks); 3rd (GA > 28 weeks)
