Longitudinal prediction of gestational weight gain trajectory according to (A) first-trimester major depressive disorder status, (B) persistent depressive symptoms (PDS), and (C) Second-trimester state anxiety score. All the models were constructed using cumulative gestational weight gain and adjusted for linear, quadratic, and cubic gestational weeks, desire to be pregnant, education, marital status, pre-pregnancy leisure time physical activity, parity, and pre-pregnancy body mass index. (A) Number of observations: 749; Number of women: 206; Average of 3.6 observations per woman. Major depressive disorder status was assessed using Mini-International Neuropsychiatric Interview. (B) Number of observations: 645; Number of women: 165; Average of 3.9 observations per woman. Persistent depressive symptoms were classified as ‘yes’ if the women presented Edinburgh Postnatal Depression Scale score ≥ 11 at the three pregnancy trimesters. (C) Number of observations: 707; Number of women: 182; Average of 3.9 observations per woman. Anxiety symptoms were measured using the Spielberger State Anxiety Inventory.
