CHICAGO (AP) - Mothers who smoke during or after pregnancy increase their babies' risk of developing colic, those vexing, inconsolable crying spells that affect up to 20 per cent of babies in their first few months of life, researchers say.
The culprit, based on studies in adults, is likely nicotine, which increases blood levels of a gut protein involved in digestion, said Brown University epidemiologist Edmond Shenassa. That may result in painful cramping that makes babies cry, he said. Shenassa and Harvard University researcher Mary-Jean Brown reviewed several studies, including six that involved more than 12,000 babies.
