We examined mental health care use in relation to depressive symptoms (Patient Health Questionnaire (PHQ-9) ≥10) among a nationally representative sample of pregnant women using data from the National Health and Nutrition Examination Survey 2005-2012. Logistic regression models estimated crude and adjusted odds ratios for mental health care use in the past year in relation to depressive symptoms. While 8.2 % (95 % CI 4.6-11.8) of pregnant women were depressed, only 12 % (95 % CI 1.8-22.1) of these women reported mental health care use in the past year.
