As seniors, these women had brain test scores that indicated one to two years of additional aging in their memory and thinking skills, compared with women who delivered normal-weight babies, according to results published June 12 in the journal Neurology. And the more low-birth-weight babies a woman had, the lower her test scores were, results show. “Previous research has shown that people who have had a low-birth-weight delivery have a higher risk of cardiovascular disease and high blood pressure,” said researcher Diana Soria-Contreras, a postdoctoral research fellow with the Harvard T.H. Chan School of Public Health in Boston. “Our study found that a history of having a child with a low birth weight may also be a marker of poorer cognition later in life,” Soria-Contreras added in a journal news release. The study involved more than 15,000 women with an average age of 62. About 8% had delivered a baby with low birth weight, defined as less than 5.5 pounds for pregnancies lasting more than 20 weeks. The women completed a series of thinking and memory tests, and also filled out a questionnaire about their pregnancy history. On average, women who had babies with low birth weigh scored lower in tests of thinking… read on > read on >
