TT国际转摘:剖腹产出生婴儿罹患肥胖的风险更高
American Heart Association News 美国心脏协会新闻
Children delivered by Cesarean section may have an increased risk for obesity compared to children born vaginally, according to research presented at the American Heart Association’s Scientific Sessions 2016.
美国心脏协会2016年科学年会研究报道称，与阴道自然分娩的婴儿相比，剖腹产出生的婴儿患肥胖的概率更高。
Compared to vaginally–delivered children, Cesarean–delivered children had 40 percent greater odds of becoming overweight or obese in childhood. This association was even greater if their mother was overweight or obese, suggesting that among obese mothers vaginal delivery may help reduce the intergenerational association of obesity.
同阴道自然分娩的婴儿相比，剖腹产出生的婴儿在童年时期超重或肥胖的几率要高40%。
This finding held even after accounting for the mother’s age at the time of delivery, race, education, pre–pregnancy body mass index, pregnancy weight gain, air pollution exposure, and the child’s birth weight.
即使是排除生产时母亲的年龄，种族，教育程度，孕前体重指数，孕期体重增长量，空气污染概率以及婴儿出生时体重这些因素的影响，这项研究依然成立。
The researchers noted that having an overweight mother is often associated with overweight or obese children, regardless of how the child is born, but the effect was stronger among women who delivered via Cesarean section.
研究者指出，不论是哪种分娩方式，超重的产妇更容易生出超重或肥胖的婴儿，剖腹产更是提高了这个概率。
“We think that the reason for the difference may be due to the beneficial microbes found in the birth canal that newborns are exposed to during a vaginal birth,” said lead study author Noel Mueller, PhD, MPH, an assistant professor of epidemiology at Johns Hopkins University. “We suspect that these microbes may benefit a child’s health, including enhancing metabolism and training the immune system.”
“我们认为导致这个差异的原因可能是婴儿在出生时从母亲产道中获得的有益微生物，”首席研究员Noel Mueller指出，Mueller拥有医学博士和公共卫生硕士双学位，同时也是美国约翰霍普金斯大学流行病学的助理教授。“我们推测这些微生物通过促进新陈代谢、强化免疫系统帮助儿童避免肥胖。”
“We need more studies to determine whether exposing Cesarean–delivered newborns to vaginal microbes at birth can reduce their future risk of metabolic disorders such as obesity.”
“我们需要进一步的研究来确定是否可以通过接触更多来自母亲产道内的健康微生物，来减少婴儿将来罹患代谢紊乱类疾病(例如肥胖)的风险。”
Researchers analyzed data on 1,441 full–term deliveries from the Boston Birth Cohort. Among the study group, 57 percent of the women who gave birth by Cesarean were obese, and 53 percent of those who delivered vaginally were obese. Children ranged from ages two to eight at the time of outcome measurement.
该项研究的分析对象来自波士顿出生队列研究中的1441名足月孕产妇。在研究组成员中， 57%的剖腹产产妇为肥胖者，另外53%的肥胖产妇则经阴道自然分娩，测量群体中涵盖了2到8岁的儿童。
