Collection and usage attributes

Guide for use:Help on this term

The day of the first visit for antenatal care is the day of the first contact with a midwife, medical practitioner, or other recognised health professional where antenatal care was provided. It does not include a contact if it was to confirm the pregnancy only or those contacts that occurred during the pregnancy that related to other non pregnancy related issues.  It does not include a first contact after the onset of labour.

Antenatal care visits are attributed to the pregnant woman. The duration of the pregnancy on that day is the same as the gestational age of the fetus or baby on that day.

Collection methods:Help on this term

To be collected at any time during the pregnancy or birth episode after the best estimate of gestational age has been determined.

The method of data collection will usually be from health records of pregnancy and/or birth.

The valid range of completed weeks for Pregnancy duration at the first visit for antenatal care is 3–46.
