Intake of dairy products and calcium and prevalence of depressive symptoms during pregnancy in Japan: a cross‐sectional study

Abstract

Objective To examine the relationship between the intake of dairy products and calcium and the prevalence of depressive symptoms during pregnancy.Design Cross-sectional study. Setting Kyushu Okinawa Maternal and Child Health Study (KOMCHS).Sample A cohort of 1745 pregnant Japanese women.Methods Dietary intake during the preceding month was assessed using a self-administered diet history questionnaire. Scores of 16 or higher on the Center for Epidemiologic Studies Depression Scale denoted depressive symptoms. Adjustment was made for age, gestation, region of residence, number of children, family structure, history of depression, family history of depression, smoking, secondhand smoke exposure at home and at work, job type, household income, education, and body mass index. In our analyses regarding dairy products in general, adjustment was also made for fish intake; in our analysis regarding calcium, adjustment was also made for the intake of saturated fatty acids, eicosapentaenoic acid plus docosahexaenoic acid, and vitamin D.Main outcome measures Depressive symptoms during pregnancy.Results Higher intake levels of yogurt and calcium were independently related to a lower prevalence of depressive symptoms during pregnancy: the adjusted odds ratios between extreme quartiles were 0.69 (95% CI 0.48-0.99, P for trend = 0.03) and 0.59 (95% CI 0.40-0.88, P for trend = 0.006), respectively. No relationships were observed between the intake of all dairy products, milk, or cheese and depressive symptoms during pregnancy. ConclusionsThe current results suggest that a higher intake of yogurt and calcium may be associated with a lower prevalence of depressive symptoms during pregnancy.

Fermented Food Consumption and Psychological Distress in Pregnant Women: A Nationwide Birth Cohort Study of the Japan Environment and Children’s Study

“…This finding differed from our expectations, based on previous research by Miyake et al (2015), who reported that a higher intake of yogurt was associated with lower prevalence of depressive symptoms during pregnancy. The difference between our results and those reported by Miyake et al (2015) may be attributable to several factors.…”

“…Miyake et al (2015) previously reported that a higher intake of yogurt may be associated with a lower prevalence of psychological distress in pregnant women, so here we assessed the effect of yogurt in detail. In particular, it was included as a continuous predictor in a working model, and a linear spline interpolation with one knot was used to represent a nonlinear association between food intake and the prevalence of psychological distress due to food refusal and overeating.…”

“…Previous studies have shown an association between nutrients and depressive symptoms during pregnancy, and suggest that higher intakes of eicosapentaenoic acid, docosahexaenoic acid, and calcium are independently associated with lower prevalence of depressive symptoms in pregnant women (Miyake et al 2013(Miyake et al , 2015. A cross-sectional study of approximately 1,700 pregnant Japanese women found that a higher intake of yogurt was independently associated with lower prevalence of depressive symptoms during pregnancy (Miyake et al 2015).…”

Alta prevalência de inadequação da ingestão dietética de cálcio e vitamina D em duas coortes de gestantes

“…Outro estudo brasileiro, agora com gestantes da capital paulista, encontrou como média de ingestão dietética diá-ria desse micronutriente 633mg 9 . Num trabalho internacional, com 1.745 gestantes japonesas, não considerando o uso de suplementos, a média de ingestão foi inferior à dos trabalhos brasileiros: 502,8mg 10 , revelando que este não é um problema restrito ao Brasil.…”
