Babies who are delivered through Caesarean section are twice as likely to become obese as those born traditionally, US research suggests. Researchers from Boston Children’s Hospital in Massachusetts found a doubling in the odds of obesity by the time the child was three years old.

The team said birth by C-section might affect bacteria in the gut, which in turn affects the way food is digested. The study looked at 1,255 pairs of mothers and children from 1999 to 2002. The mothers joined the study before 22 weeks of pregnancy. Their babies were measured and weighed at birth and this was repeated at the age of three.

About one in four of the deliveries were C-section births and the remainder were vaginal deliveries. The team found a link between body mass, skin thickness and how a child was born. They also found that mothers who delivered by C-section tended to weigh more than those delivering traditionally, something which is known to influence obesity.

The researchers said another possible explanation was the difference in the composition of gut bacteria acquired at birth between the two delivery methods. They suggested expectant mothers who choose a C-section should be made aware of the obesity risk to their babies.

美國研究顯示,以剖腹方式產下的嬰兒,過胖機率是以傳統方式出生的小孩的兩倍。麻州波士頓兒童醫院研究人員發現,到孩子三歲時,其過胖的機率增加一倍。

團隊說,剖腹生產可能影響腸中的細菌,結果影響食物消化方式。研究從一九九九年到二○○二年觀察一千兩百五十五對母親與嬰兒,母親在懷孕滿二十二週前加入這份研究,孩子的體重出生時量一次,三歲時再量一次。

約四分之一的分娩是剖腹生產,其餘則是經陰道分娩。團隊發現,身體質量、皮膚厚度與小孩出生的方式有關聯,他們也發現,剖腹生產的母親,體重似乎比以傳統方式生產的母親重,這是已知影響過胖的因素。

但研究人員說,另一項可能的解釋是,出生時取得的腸道細菌結構,兩種分娩方式不同。他們認為,選擇剖腹生產的懷孕母親,應該被告知她們的寶寶有過胖風險。
