↵a Mean times per week. Mild-intensity exercise refers to activities such as yoga, golf, and easy walking. Moderate-intensity exercise refers to activities such as fast walking, tennis, cycling, and dancing. Vigorous exercise refers to activities such as jogging and aerobics.
↵b Denotes significant difference between groups at P<0.05.
↵c Follow-up scores are adjusted for baseline. Note: follow-up data: usual care, n = 15; exercise, n = 16.
EPDS = Edinburgh Postnatal Depression Scale.
