Objectives: Women with high body mass index (BMI) have increased risk for symptoms of anxiety and depression during pregnancy and postpartum. In this pre-specified secondary analysis from the ETIP trial, our aim was to examine effects of supervised exercise during pregnancy on psychological well-being in late pregnancy and postpartum among women with a pre-pregnancy BMI ≥ 28 kg/m2.
Design: Single-centre, parallel group, randomized controlled trial.
Setting: University Hospital, Norway
Intervention: The exercise group was offered three weekly supervised exercise sessions (35 minutes of moderate intensity walking/running and 25 minutes of resistance training), until delivery.
Primary and secondary outcomes measures: Primary analyses were based on intention to treat, with secondary per-protocol analyses. To assess psychological well-being, we used the «Psychological General Well-Being Index» (PGWBI) at inclusion (gestational week 12-18), late pregnancy (gestational week 34-37), and three months postpartum. We assessed postpartum depression using the «Edinburgh Postnatal Depression Scale» (EDPS).
Results: Numbers completed data collection: Late pregnancy 72 (exercise 38, control 36), postpartum 70 (exercise 36, control 34). In the exercise group, 50% adhered to the exercise protocol. Baseline PGWBI for all women was 76.4±12.6. Late pregnancy PGWBI; exercise 76.6 (95% CI 72.2, 81.0), control 74.0 (95% CI 69.4, 78.5) (p = 0.42). Postpartum PGWBI; exercise 85.4 (95% CI 81.9, 88.8), control 84.6 (95% CI 80.8, 88.4) (with no between-group difference, p = 0.77). There was no between-group difference in EDPS; exercise 2.96 (95% CI 1.7, 4.2), control 3.48 (95% CI 2.3, 4.7) (p = 0.55).
Conclusions: We found no effect of supervised exercise during pregnancy on psychological well-being among women with high BMI. Our findings may be hampered by low adherence to the exercise protocol.
