Özkan SA, et al. - Researchers examined if and how an exercise program affects the severity of postnatal depression in women who had a spontaneous vaginal delivery via performing a randomized control trial including 65 postpartum women residing in a city located in south‐eastern Turkey. In the first postpartum month, participants were randomly assigned to either the experimental group (n = 40), in which they performed exercises for 4 weeks, or to the control group (n = 40), in which they received standard care. The Edinburgh postpartum depression scale. The exercises (16.41 ± 1.61) and control group (15.74 ± 2.35) had similar pretest mean depression scores. After the 4‐week exercise program, the posttest mean scores of the exercises (7.29 ± 1.67) and control (12.54 ± 2.65) group participants showed a statistically significant difference. Outcomes support the effectiveness of the 4‐week exercise program in reducing the severity of depressive symptoms experienced in the postpartum period. Hence women in this period should be provided with exercise training by nurses and midwives providing care in the postpartum period.
