Glossary Definition

Last Updated: 2010-11-17


A measure of the adequacy of prenatal care by a healthcare provider. Knowledge of three birth-related outcomes are required to calculate R-GINDEX:

    a) the gestational age of the infant (date of pregnancy and birth);
    b) the trimester during which prenatal care began; and
    c) the total number of prenatal visits during pregnancy.

There are six major categories of prenatal care outcomes identified for the index:

  1. Inadequate prenatal care utilization
  2. Intermediate prenatal care utilization
  3. Adequate prenatal care utilization
  4. Intensive prenatal care
  5. No care
  6. Missing information on prenatal care
For more detailed information, please read the Revised-Graduated Prenatal Care Utilization Index (R-GINDEX) concept.
