Overweight and obese moms face more risk of early births

21.07.2010
A new study by researchers at McMaster University shows overweight and obese women face greater risks of preterm births. Their babies may suffer serious health problems from being born too soon, especially earlier than 32 weeks.

"It looks like the heavier the woman, the higher the risk," said Dr. Sarah McDonald, associate professor in the Michael G. DeGroote School of Medicine's Department of Obstetrics and Gynecology. She led a meta-analysis of 84 studies comparing overweight and obese to normal weight women.

The analysis found overweight or obese women have a 30 per cent greater risk of induced preterm birth before 37 weeks and that risk climbs to 70 per cent for very obese women. (A full-term pregnancy is 40 weeks).

Overweight or obese women also had a higher risk of early preterm birth – before 32 or 33 weeks, again with higher risks in heavier women. The research appears in the latest issue of the British Medical Journal (BMJ).

"Preterm birth and low birth weight are leading predictors of neonatal morbidity and mortality and morbidity or illness through childhood," said McDonald, adding there are also implications for the child's family and the health care system.

She said it is not yet clear why there is a link between a mother's weight and preterm birth.

Overweight and obesity is now the most common pregnancy complication in many developed, and some developing countries. Statistics Canada reports 29 per cent of Canadian women are overweight and 23 per cent are obese.

Two-thirds of Hamilton area women who are pregnant are overweight or obese, according to local data. No similar provincial or national statistics are available.

McDonald said the popular view that a pregnant woman is eating for two is not true. "It's just not right. Typically, women should add about 300 calories a day – the equivalent of a large glass of milk and a piece of fruit - in the latter half of their pregnancy," she said.

Counselling women before they become pregnant on the potential risks to overweight and obesity using a multi-pronged approach is required, McDonald said.

"Family doctors, nurses, obstetricians, public health nurses, and dieticians are all important in delivering a consistent message. Women often make many positive lifestyle changes for their pregnancies to have healthier babies, so now we need to make sure that they are aware of these findings so they can optimize their weight before pregnancy."

The research was supported by a Canadian Institute of Health Research (CIHR) operating grant. McDonald is supported by a CIHR New Investigator Award.

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

Im Focus: Entangled atoms shine in unison

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.

The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
