Dairy products intake and the risk of postpartum depression among mothers: A pilot study

Introduction:Postpartum depression is a prevalent consequence of childbirth experienced by many women. There has been evidence linking dairy intake during pregnancy with a reduction in postpartum depression symptoms. However, there is still a lack of understanding regarding the effects of postpartum dairy consumption on postpartum depression. Objectives:To examine whether dairy products intake and calcium in dairy is associated with postpartum depression. Methods:A pilot study was conducted (n = 49 postpartum women). A food frequency questionnaire was used to evaluate the participants' consumption of calcium and dairy products during pregnancy, and the Edinburgh Postnatal Depression Scale was used to screen for postpartum depression symptoms. Results:Of 49 participants, 26 (53%) were at risk for postpartum depression (Edinburgh Postnatal Depression Scale & GT; 12). Consuming >1 serving of Laban per day is significantly associated with reduced risk of postpartum depression (odds ratio = 0.01, 95% confidence interval [0, 0.3]). Total dairy intake >1 serving per day is significantly associated with reduced risk of postpartum depression (odds ratio = 0.17, 95% confidence interval [0.03, 0.83]). No significant association was found between the postpartum intake of milk, cheese, yogurt, or calcium and postpartum depression. Conclusion:Our findings indicate that higher total dairy intake was associated with a lower likelihood of postpartum depression. Further assessment with a larger sample size of participants could provide additional insight into the potential of dietary dairy to mitigate postpartum depression.
