Scores of 16 or higher on the Center for Epidemiologic Studies Depression Scale denoted depressive symptoms.

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.</p> </sec> <sec id="bjo12972-sec-0006" sec-type="section"> <title>Main outcome measures</title> <p>Depressive symptoms during pregnancy.</p> </sec> <sec id="bjo12972-sec-0007" sec-type="section"> <title>Results</title> <p>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, <italic>P</italic> for trend = 0.03) and 0.59 (95% CI 0.40–0.88, <italic>P</italic> for trend = 0.006), respectively.
