Maternal age and the risk of low birthweight and pre-term delivery: a pan-Nordic comparison
(2023) In International Journal of Epidemiology 52(1). p.156-164- Abstract
- Advanced maternal age at birth is considered a risk factor for adverse birth outcomes. A recent study applying a sibling design has shown, however, that the association might be confounded by unobserved maternal characteristics. Methods: Using total population register data on all live singleton births during the period 1999-2012 in Denmark (N = 580-133; 90% population coverage), Norway (N = 540-890) and Sweden (N = 941-403) and from 2001-2014 in Finland (N = 568-026), we test whether advanced maternal age at birth independently increases the risk of low birthweight (LBW) (
