Pregnancy weight gain in twin gestations and maternal and child health outcomes at 5 years.

ABSTRACT:

Objective

Current guidelines for maternal weight gain in twin pregnancy were established in the absence of evidence on its longer-term consequences for maternal and child health. We evaluated the association between weight gain in twin pregnancies and the risk of excess maternal postpartum weight increase, childhood obesity, and child cognitive ability.

Methods
