“…The provision of guidelines for twin pregnancies was an important step given the association between adverse outcomes and both insufficient (e.g., preterm delivery [Lipworth et al, 2022 ; Zhong et al, 2021 ], gestational diabetes mellitus, low birthweight, neonatal intensive care unit admission [Zhong et al, 2021 ]) and excessive (e.g., Pre‐eclampsia [Lipworth et al, 2022 ], gestational hypertension, caesarean section, preterm birth [Zhong et al, 2021 ]) GWG in twin pregnancies. Furthermore, compared to singleton pregnancies, twin pregnancies have a higher incidence of poor obstetric and perinatal outcomes associated with insufficient GWG (e.g., foetal and neonatal death, small for gestational age [GA]) and of increased GWG and pregnancy complications associated with excessive GWG (e.g., Pre‐eclampsia, gestational diabetes, caesarean section [Bodnar et al, 2014 ; Hutcheon et al, 2018 ; Widen, 2018 ]).…”
