Description
Teenage pregnancy is pregnancy in human females under the age of 20 at the time that the pregnancy ends. A pregnancy can take place in a pubertal female before menarche (the first menstrual period), which signals the possibility offertility, but usually occurs after menarche. In well-nourished girls, menarche usually takes place around the age of 12 or 13.
Pregnant teenagers face many of the same obstetrics issues as women in their 20s and 30s. There are, however, additional medical concerns for mothers aged under 15. For mothers aged 15–19, risks are associated more with socioeconomic factors than with the biological effects of age. However, research has shown that the risk of low birth weight is connected to the biological age itself, as it was observed in teen births even after controlling for other risk factors (such as utilization of antenatal care etc.).
