Changes in maternal and paternal body composition during the transition to parenthood ( TRANSPARENTS )
Authors' conclusion
Increases in latent means correspond to unfavorable changes in BMI, body fat percentage, and waist circumference. These changes were observed from the beginning of pregnancy up to 6 months post partum. Weight management for both women and men during pregnancy and the early postpartum period is recommended and fathers should be included in pre- and postnatal standard care.

Main finding
As reported in the abstract
Change in latent mean of body composition
- Women: PP6WK − PG12
- +1.115, SE: 0.117, p < 0.001
- Women: PP6M − PP6WK
- −0.368, SE: 0.107, p < 0.001
- Women: PP6M − PG12 (remained above baseline)
- +0.747; SE: 0.115, p < 0.001
- Men: PP6WK − PG12
- +0.370, SE: 0.075, p < 0.001
- Men: PP6M − PG12
- +0.366, SE: 0.084, p < 0.001
