Mediterranean diet linked to lower risk of preeclampsia in pregnancies – The Hill


Story outline


  • A new study published in JAMA Network Open found an association between a Mediterranean diet and reduced adverse pregnancy outcomes.

  • The study, conducted by the Smidt Heart Institute in Cedars-Sinai, examined the diets of over 7,700 pregnant women.

  • Researchers found that women who ate a predominantly Mediterranean diet had a 28% lower risk of developing pre-eclampsia.

A diet rich in vegetables, fruits, nuts, and seafood may help women lower their chances of developing serious pregnancy complications, according to new research.

A study published Thursday at the JAMA Network Open claims that women who become pregnant following a Mediterranean diet have a “significantly” lower risk of developing pre-eclampsia during pregnancy.

Pre-eclampsia is a potentially life-threatening pregnancy complication that can cause high blood pressure and stress on the mother’s heart. If left untreated, it can weaken the blood supply to the developing fetus and weaken the mother’s kidney and liver function.

According to the study, researchers at the Smidt Heart Institute in Cedars-Sinai monitored more than 7,798 pregnant mothers for the study between 2010 and 2013, and between June 2021 and April 2022. We analyzed the results during

Of study participants, 10% were over the age of 35. 17% were Hispanic. Eleven percent are identified as non-Hispanic and four percent as Asian. Another 20% of participants were considered obese at the start of the study.

Researchers will collect data on maternal eating habits for three months before and after conception to assess maternal adherence to a Mediterranean diet that emphasizes plant-based foods, whole grains, and healthy fats. Did.

Mothers were each given a score from 0 to 9 based on their diet. Researchers found that a mother with a “high Mediterranean diet score,” or scores between her 6 and 9, was associated with her 21% lower risk of developing adverse pregnancy outcomes, such as pre-eclampsia. Did.

These same mothers had a 28% lower risk of developing pre-eclampsia and eclampsia.

Other pregnancy complications studied by researchers include gestational diabetes, high blood pressure, stillbirth, premature birth, and low birth weight of the baby.

The study also found that mothers who scored higher on the Mediterranean diet were 37% less likely to have gestational diabetes.

“There were no differences by race, ethnicity, and pre-pregnancy body mass index,” said the study. “However, the association was stronger among women over the age of 35.”

The study adds to a body of research supporting the positive health impacts of the Mediterranean diet, according to study senior author Dr. Natalie Bello of the Smidt Heart Institute. He said more long-term studies are needed to decide whether to adopt. Health complications can be prevented during and during pregnancy.
