The big issue is that the study was of Israeli women, not Americans, and there's some big differences between the two.
UTHealth and UT Physicians maternal fetal specialist Dr. Nana Ankumah said keep in mind the study is of a small group from another country.
"Israel has a very different population from the United States. Women tend to have a lower rate and may have less co-morbidity, such as hypertension, diabetes, those kind of things than we see in women in our population," said Ankumah. "Our baseline health status may not be the same as another country, and so it's hard to extrapolate those findings directly to United States."
Complications for women older than 35 and pregnant can include gestational diabetes, hypertension, premature birth, and caesarian sections.
