(legend) 1Logisitic regression model of best fit was adjusted for parity (categorical) and pre-pregnancy body mass index (continuous) for 3-month analyses, and for parity (categorical), education (categorical), and pre-pregnancy body mass index (continuous) for 6-month analyses. 2IIFAS score range among participants in the 3-month analyses: Quartile 1: 39.00-62.00; Quartile 2: 62.01-67.00; Quartile 3: 67.01-72.00; Quartile 4: 72.01-83.00. IIFAS score range among participants in the 6-month analyses: Quartile 1: 39.00-62.25; Quartile 2: 62.26-67.00; Quartile 3: 67.01-73.00; Quartile 4: 73.01-83.00.
