Teenage pregnancy can occur after the start of ovulation, which is usually after the onset of periods around age 12 or 13. Pregnant teenagers face the same issues as other women but those under 15 are less developed physically to have a healthy pregnancy or birth. Risks of low birthweight and preterm labor are associated with younger biological age. Teenage pregnancies are connected to lower education and poverty. Rates of teenage pregnancy are higher in Africa and lower in Asia, with about 2.5 million females under 16 and 16 million aged 15-19 having children each year in developing nations.
