Canadian infants appear to have some of the highest levels of colic in the world, according to a new study that attempted to create the first international crying chart to determine why some babies cry more than others.
Colic has long been defined as infant crying that lasts longer than three hours a day for at least three days a week. For parents who cant comfort their child with the usual rocking, swaddling, or diaper-changing, the unexplained crying of colic can become heart-wrenching.
To try to understand where colic levels are highest, researchers at the University of Warwick that involved close to 8,700 infantsfrom eight countries whose parents kept diaries of their babies crying habits.
They found that in Canada, 34.1 per cent of babies have colic by age three to four weeks old. In the U.K., 28 per cent of infants meet the threshold of colic at age one to two weeks old. And in Italy, 20.9 per cent had colic around age eight to nine weeks.
Denmark, on the other hand, has one of the lowest rates, with only 5.5 per cent of babies aged 3 to 4 weeks meeting the definition for colic. Germany also had low colic rates, of only 6.7 per cent at 3 to 4 weeks.
Dieter Wolke, the study lead author and a professor in Warwicks department of psychology, says the average four-week-old baby cries for about two hours a day.
In Canada, babies cried on average for 30 minutes more, so 2-1/2 hours a day, he told CTV News Channel from Munich.
