Early childhood weight trajectory differences in twins, singletons, and gestational-age matched singletons.

ABSTRACT:

Objective

Understanding of twin growth in the United States (US) is based on outdated or predominantly non-Hispanic White samples, and the age at which twins catch up to singletons is unclear. In this study, we characterized normative weight trajectories of twins and singletons in a contemporary, diverse cohort.

Methods

Data were from the PROMISE study, an electronic health record-based cohort of pregnant people and their children in the US (2005-2021). The Jenss model was used to characterize weight trajectories from 0 to 24 months of age. Twins (n = 716) were compared to the full cohort of singletons (n = 40,075) and a matched sample with similar gestational age at birth (GA) (n = 7160).

Results

Male and female twins had lower birth weight compa
