Study finds obese pregnant women that maintain or lose weight save money and have healthier newborns

A recent study conducted by The University of Texas Medical Branch (UTMB) at Galveston shows that severely obese women who maintained or lost weight during pregnancy had healthier babies and lower health care costs.

“The ob-gyn department is justifiably proud of this result, which required a lot of close attention to the mothers’ prenatal care,” said David McCormick, clinical professor of pediatrics in the Division of General Academic Pediatrics at UTMB. “We were quite surprised by the relatively large proportion of mothers who responded to the educational efforts. We were especially happy to see the benefits on pregnancy-related costs and the favoruable infant health outcomes.”

The study, to be published in the journal Clinical Obesity, compared 82 severely obese pregnant women with 85 healthy weight women. The obese mothers experienced more medical problems during pregnancy, higher medical costs and longer lengths of hospital stay compared to non-obese women. Twenty-six per cent of the obese mothers maintained or lost weight during pregnancy and experienced lower medical costs and gave birth to healthier infants.

Neonatal intensive care consumed 78 per cent of total hospital costs for infants of the obese women who gained weight, but only 48 per cent of costs for infants of obese women who maintained or lost weight.

Total medical charges – including hospital and physician – were 37 per cent higher for labour and delivery care for obese mothers and their infant compared to non-obese mothers and their baby.

The findings are important, McCormick said, because 34 per cent of reproductive-aged women living in the USA are obese. Of these, nearly 19 per cent are morbidly obese. The study found that, compared with women whose body mass index was less than 25, women with severe obesity were also more prone to preeclampsia, gestational diabetes, insulin use, cesarean section and prolonged hospitalisation.

Compared with infants of normal-weight mothers, infants of obese mothers experienced more complications such as stillbirth, prematurity, excessively large size and neonatal trauma.

Infants of the one-quarter of women with severe obesity who maintained or lost weight during pregnancy were less likely to suffer the adverse consequences of abnormal birth weight. No premature infants or overweight babies were born in this group.

Caregivers in the prenatal clinics advised the mothers on nutrition and exercise, and provided them with written educational materials. Study authors suggest that more research will be needed to fully assess the health risks for infants when an obese woman maintains or loses weight during pregnancy.

Researchers obtained data for the study by reviewing the medical records of 2215 women who delivered at UTMB from June through December 2009.
