More twins are born as mums wait until 30s

MORE women are having twins these days. The reason? Older mothers and fertility treatments.

One in every 30 babies born in the US is a twin -- an astounding increase over the last three decades, according to a new report. In 1980, only one in every 53 babies was a twin.

"When people say it seems like you see more twins nowadays, they're right," said Joyce Martin, an epidemiologist who co-authored the Centers for Disease Control and Prevention report.

Some increase was expected, as more women are waiting until they are over 30 to have babies. For some unknown reason, mothers in their 30s are more likely to have twins than younger or older women. As much as a third of the increase can be attributed to that, Martin said.

The rest of the rise is due to fertility drugs and treatments, experts said. "There are more older moms and more widespread use of fertility-enhancing therapies," she said.
