Predefined secondary outcomes
Eight weeks postpartum, a mean difference of 5.5 (95% CI: 1.0–10.1) p=0.04 (corrected for multiple testing) in WHO-5 score between the intervention and the control group was seen, the mean WHO-5 score being 60.2 (95% CI: 57.1–63.3) in the intervention group and 54.7 (95% CI: 51.3–58.1) in the control group (Table 2).
No difference was found in maternal or infant outcomes (Table 3) except for induction of labour where 27.2% in the control group versus 15.8% in the intervention group had their labour induced, p=0.02. There was no difference with regards to the medical indications for induction in the two groups (data not shown). The groups also did not differ with regards to sick leave, contacts to the hospital, or length of hospital stay (Table 4). Finally, no major adverse effects or health problems resulting from the exercise intervention were reported.
