Obese couples could be risking health of future infants, studies say

Diet and lifestyle during the pre-conception period can profoundly affect the childs growth, researchers find

Couples who are obese, as well as those who smoke and beverage alcohol, could be risking the health of their future infants, say experts who are calling for far more awareness of the effects of modern lifestyles on newborns in the womb.

A series of three scientific papers in a leading medical journal spell out the consequences of poor diet and lifestyles for the next generation. They urge schools, GPs and nurses to talk to young people and those who may be planning their own families about how to be fitter and healthier before they embark on pregnancy.

What happens in the “pre-conception” period can have a profound impact on the growth, developing and long-term health of children, they say. Some of the interventions that exist to help pregnant women be healthier are taken up too late. Folic acid assistances avoid neural flaws, but most women do not start to take it until they have seen a GP to confirm their pregnancy, which can be after a month or two. The crucial time is in the early days and weeks.

Lead author Prof Judith Stephenson of University College London said:” The key message is to act earlier, before conception. The notion that there are things you can do before the pregnancy that will affect the health of the baby is not always comprehended.

” The general position of most women is,’ Once I’m pregnant I will go and see the GP and things will get going from there .'”

But she said the scientists did not want to distress mothers who might have been overweight when they had their children.” All the evidence points to early events being very influential in later life, but you are not doomed at that stage ,” she said.” Things you do throughout childhood and adolescence also have a powerful influence on future health .”

The global series of three newspapers in the Lancet also highlights the risks of undernourished daughters in the developing world having stunted babies with poor cognitive growth. It is a very serious problem that needs to be better tackled, but obesity is now more widespread.” In many low, middle, and high-income countries, up to 50% of women are overweight or obese when they become pregnant ,” say the experts.

” In high-income countries, teens have the poorest diets of any age group … it is a crucial period for establishing long-term health risk .”

Obesity, they say, is associated with increased risk of most major adverse outcomes for pregnant women and their babies. It can make it hard to conceive and complicate pregnancy- girls are at risk of high blood pressure, called pre-eclampsia, for instance. It increases the chances of birth defects, stillbirth, low-weight newborns, unsuccessful breastfeeding and even the death of the mother.

The issues is not only with the weight of the mother. Obesity in the parent has been linked to impaired fertility and an increased risk of chronic disease in the child.

Couples are already advised to stop smoking and drinking when a woman is pregnant. Now they should be advised about their nutrition and losing weight as well. One of the best opportunities to intervene is when a woman visits a nurse or a family planning clinic to have a contraceptive implant or coil removed. But GPs could also ask whether couples are considering having a family during any other routine visit.

There is a window of opportunity to get the healthy message across when couples are thinking of having a child, said Stephenson.” Couples are very motivated around this time ,” she said. In one pilot study, a researcher suggested to obese women planning to get pregnant that they lose a lot of weight first.” Two-thirds gave it a go and a third completed it ,” she said.

Couples need support, however.” It is usually not enough to simply educate or give advice, as knowing something is good for you is rarely sufficient to change behaviour ,” says one of the papers.

The Royal College of Obstetricians and Gynaecologists said it was very concerned that 96% of women of reproductive age had low levels of iron and folic acid.” This is yet another piece of proof adding to the overwhelming need for the government to add folic acid to flour ,” said Prof Janice Rymer, vice-president.” This simple measure will reach women most at risk in our society who have poor dietary and socioeconomic status, as well as those women who may not have planned their pregnancy .”

The college also supported the call for education about health and fitness prior to having infants.” Education from an early age- ideally from adolescence- about the need to maintain a healthy diet and weight will not only improve the health of individuals, but also the health and quality of life of future generations ,” Rymer said.
