Obesity May Increase Risk Of Preterm Birth

Studies have revealed that the babies born to overweight women are more likely to be premature babies and they also pose a severe threat to their mothers as well. Obesity is considered as a well known threat to pregnancy and can pose severe complications for the growing fetus.

Although there are different views regarding the impact of the mother’s weight on early delivery research has confirmed that overweight women have a greater risk of delivering their baby before 32 weeks of gestation and a higher risk of induced delivery before 37 weeks of gestation. The studies also claim that the babies who are born this early tend to remain sick and will remain in a nursery for a longer time. In the article below we will be discussing the relation between obesity and preterm birth.

Obesity And Preterm Birth:

Studies have proved that the most common complication during pregnancy is caused if the women are overweight. It has been found that the women who are overweight at the time of pregnancy have a risk of many health complications, not only for themselves but also for the developing fetus, as well as premature birth, congenital heart defects etc.

A recent study was conducted to establish a relationship between the weight of the mother and premature babies. The research was conducted on 1,095 women and drew the following conclusions:


•   There was a 37% risk of induced premature birth, if the mother is overweight.

•   It was also concluded that the heavier the mother the greater the risk.

•   In women who are highly obese, the risk of premature birth can be up to 70% as compared to normal weight women.

Babies who are born in between 37-42 weeks are called full term babies, while those who are born before 37 weeks are premature babies. It has been found that premature babies or babies with low weight are the leading causes of infant deaths and illness in childhood. There are several problems associated with a premature birth, like problems related to breathing, some everlasting conditions like mental retardation, learning and behavioral problems, cerebral palsy, problems related to behaviors, learning and vision and/or hearing loss.
