Collection and usage attributes | |
Guide for use: | 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 visit where the sole purpose of contact is to confirm the pregnancy, or those contacts that occurred during the pregnancy that related solely to 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: | 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. |
