2021.09.06  65

A research team from the Department of Gastroenterology at Samsung Medical Center and Kyunghee University Hospital assessed 6,893 women aged 30 to 50 who had given childbirth and participated in the Korean National Health and Nutrition Examination Survey, which was conducted from 2010 to 2018.


The average age of all subjects were 41 years old, and 15.2% were diagnosed with nonalcoholic fatty liver disease (NAFLD).


The research team calculated the degree of fatty liver according to the breastfeeding period of the participants by considering other indicators such as age, obesity, waist circumference, dyslipidemia, and diabetes.


As a result, the risk of the disease was reduced by 26% when the duration of breastfeeding was within 1 to 3 months, 30% in 3 to 6 months, and 33% in 6 to 12 months. Breastfeeding for more than one year lowered the risk of the disease by 36%.


The research team interpreted the reason for this result by stating nonalcoholic fatty liver disease is fundamentally related to metabolic disease.


Therefore, breastfeeding is reported to be effective in preventing and improving metabolic diseases, which includes improving insulin resistance and raising good cholesterol levels.


This study was published in the Hepatology, Impact Factor 17.425, a highly distinguished publication in the field of liver science.
