The rate of preterm delivery of Obese or overweight pregnancies is 25% more than stated.
Department of Reproductive Epidemiology, Karolinska Institute Reproduction Epidemiology Department researched led by Prof.Sven Cnattingius and recorded 1 million 500 thousand women who gave birth between 1992 and 2010.
In the study, body mass indexes were calculated for women during pregnancy.
Women with indexes of 18.5 and 24.9 were normal weight, those with 25 and 29.9 were overweight, those with 30 and over were defined as obese.
The probability of giving birth to an overweight woman is 25%, but it’s up to 60% in obese women.As the weight increases, the chance of the baby being born earlier is increased threefold.
