Children born to moms who had the procedure before pregnancy have healthier hearts and less risk of obesity than their siblings born before the mom had surgery.

An overweight woman who has weight-loss surgery before becoming pregnant may help break the cycle of obesity in her family, according to a new study.

Researchers found that children born to women who had weight-loss surgery before pregnancy have improved heart health and a lower risk of obesity compared with their siblings who were born before the mother had surgery. The study was published last week in the Journal of Clinical Endocrinology & Metabolism.

Previous research shows a woman's weight and her tendency to develop diabetes and heart disease can influence the long-term health of her fetus, predisposing the child to metabolic problems related to obesity. Obese young women who are planning to have children some day should try to lose weight through weight-loss surgery or behavioral changes.

The researchers studied 49 women who had undergone weight-loss surgery and their 111 children, who were ages 2 to 25. About half of the women had given birth before the surgery and again after. The other women gave birth either before or after surgery.

The study showed that the children born after their mother's surgery had reduced birth weight and waist circumference and were three times less likely to become severely obese compared with siblings born before the surgery. These children also had improved cardiovascular markers, such as reduced insulin resistance and lower cholesterol and inflammation.

怀孕期前做过减肥手术妈妈们生的孩子比没有做手术妈妈的孩子拥有更好的心脏且更不易得肥胖病。

根据新的研究，超重妇女在怀孕期前做减肥手术能打破家族中的肥胖遗传链。

上周在临床内分泌和新陈代谢杂志上的研究表明：在怀孕期前做减肥手术可以增强孩子心脏功能，并与那些没有做减肥手术妈妈的孩子比，他们更不容易得肥胖病。

之前的研究说妈妈们的体重、患肥胖症倾向和心脏病都会影响胎儿的长期健康，诱导孩子产生与肥胖有关的新陈代谢问题。年轻肥胖的女人如果打算怀孩子应该试着通过手术或运动减肥。

研究人员对49位有肥胖症的妇女和他们111位年龄在2-25岁间的孩子做出了研究。其中大约一半妇女在手术前后都有生孩子，而另一半要么在术前或术后生的孩子。

研究表明生于手术后的孩子胎重和腰围均减少，比起生于手术前的孩子，他们患严重肥胖的概率小三倍。他们的心脏血管也得到改善，胰岛素抵抗、胆固醇含量及炎症发生率均减降低。
