When women remain in state, it is common for mothers and grandmothers to offer advice based on generational wisdom and beliefs of the place where they come from.Despite the little faith with which this knowledge is heard today, in In recent years, a handful of studies have found that some of the most extravagant old ideas may have some scientific merit after all.Find out which pregnancy myths are true.
3 myths about pregnancy that have been corroborated by studies
1.A long and difficult labor means that the baby is a child In 2003, a team of doctors I analyze more than 8,000 births in a single hospital in Ireland between 1997 and 2000, excluding women who gave birth prematurely or who needed to have their birth induced.
By observing all numbers, the difference between sexes was small, but notable .
On average, births for boy births lasted just over six hours , while the births of girls took a little less than six.Women who gave birth to children were also more likely to have complications during childbirth , requiring caesarean sections 6% of the time (compared to 4% for girls) and forceps in 8% of cases (compared to 6% in the case of childbirth deliveries).
In general, 29% of childbirths ended up requiring some kind of extra intervention ; For girls, it was 24%.
2.To have a girl, stay away from bananas
Eat more in the pre-pregnancy period also can make it more likely that the baby is a child.
In 2008, a study published in the Proceedings of the Royal Society magazine took 740 women who were pregnant for the first time to describe their diets during the year prior to conception, and then divided them into three groups based on calorie intake.
Women in the upper third of the study, who consumed more calories, had boys 56% of the time, those who consumed fewer calories, had girls in 55% .
This is where the old advice on eat bananas before conception to have a child enter The authors of the study found that calorie intake was not the only thing that made a difference, specific nutrients did too. Eating a lot of potassium (abundant in bananas) was linked to children , like diets high in calcium and sodium.
3.Heartburn is an omen of a hairy baby
Mothers who want to know before of time if your baby will be hairy or can't find out for his heartburn.
In 2006, for a study in Birth magazine, a team of researchers from Johns Hopkins University followed 64 women during their pregnancies, 28 of whom reported moderate or severe heartburn.
Within that group, 23 women ended up having babies with average or above average hairiness At the opposite end of the spectrum, of the 12 women who reported no heartburn at all, ten of them gave birth to children who were less p eludos than the average newborn.
Heartburn was not, however, what determined the abundance or lack of hair.Rather, the authors of the study argued, both were caused by a third factor : pregnancy hormones.
