[헬스코리아뉴스 / 임대현] Depression is one of the most common mental disorders in modern people. The importance of prevention is being emphasized as social problems and costs caused by depression such as interpersonal problems and suicide are also increasing rapidly.
In particular, women have twice the incidence of depression than men, and are known to have a high risk of depression at certain times, such as postpartum depression or menopausal depression.The more dietary fiber, such as fruits and vegetables, in premenopausal women, the higher the risk of developing depression. A domestic research result that is low has been published and is attracting attention.
Chung-Ang University Hospital (Han-Jun Lee), Professor Jeong-ha Kim and Yoon-sun Kim, majors in Family Medicine, recently announced,’Inverse assosiation between dietary fiber intake and depression in premenopausal women: a nationwide population. -based study)’.
Using data from the National Health and Nutrition Survey, the research team measured the average dietary fiber intake of women with and without depression in order to analyze the correlation between dietary fiber intake according to menopause and depression in 5807 women.
As a result, average dietary fiber intake among all women was higher in the non-depressed group than in the depressed group. (Total female dietary fiber intake: 14.07±0.11g/1,000kcal[비우울증 그룹] vs 12.67±0.45g/1,000kcal[우울증 그룹]. g/1,000kcal: The number of grams of dietary fiber intake per 1000kcal of energy intake per day).
In particular, premenopausal women were found to have significantly higher dietary fiber intake in the non-depressed group than in the depressed group. (Female dietary fiber intake before menopause: 12.45±0.13g/1,000kcal[비우울증 그룹] vs 10.30±0.46g/1,000kcal[우울증그룹]).
In addition, the research team found that a 1g/1000kcal increase in dietary fiber intake per day in pre-menopausal women correlated with a 5% decrease in the prevalence of depression, whereas in postmenopausal women this difference did not appear.
“The inverse association between dietary fiber intake and depression in premenopausal women identified in this study is the’brain-gut axis’, which is the interaction between the gastrointestinal tract and the central nervous system,” said Yoon-sun Kim, a doctor of family medicine at Chung-Ang University Hospital. “There is a possibility that it may be related to the interaction and female hormones,” he said. “We hope that it will become a preliminary study to reveal the causal relationship in the future and contribute to preventing depression through non-drug approaches such as dietary change.” .
This research paper was published in the February 2021 issue of Menopause-The Journal for The North American Menopause Society, an SCI(E)-level international academic journal.
