A joint research team of the National Institute of Public Health, Ehime University, the University of Tokyo, and Ryukyu University has announced for the first time in the world research results suggesting that milk intake during pregnancy has a preventive effect on postpartum depressive symptoms. It was published in "Research".
Postpartum depression is a type of depression that causes depressed mood and decreased motivation, and is said to be caused by a combination of various factors such as changes in hormone balance, fatigue due to childbirth, anxiety about childbirth, and lack of sleep.
Only one study has so far investigated the relationship between dairy intake and postpartum depression, and this study is also significant between dairy intake and postpartum depression. No association was found.This time, the research group used data from the "Kyushu-Okinawa Maternal and Child Health Study," which was a follow-up survey of mothers and children born during pregnancy, and targeted 3 mothers who participated in the survey at the age of 4 to 1319 months. We investigated the relationship between nutrition and postpartum depression.
As a result of the survey, when the frequency of postpartum depression in the group with 0 milk intake was set to 1, the group with the highest milk intake during pregnancy (1 grams per day on average) was almost halved to 187.5. For the first time in the world, it was recognized that the risk of postpartum depression was significantly reduced by ingesting milk.By the way, no significant association with postpartum depression was found when taking total dairy products, yogurt, cheese, calcium, and vitamin D.
In today's world, where it is said that 10-15% of postpartum women suffer from postpartum depression, this result is of great interest.In the future, in order to ensure the relationship between milk intake and the reduced risk of postpartum depression, it is hoped that further research will be conducted and reliable evidence will be accumulated.
