Increasing Use of Antenatal Magnesium Sulphate Prior to Preterm Birth for Preventing Cerebral Palsy in Australia and New Zealand, 2012-2020: A Binational Registry Study.

We assessed the use of magnesium sulphate prior to preterm birth for preventing cerebral palsy in an Australian and New Zealand registry study. Use increased markedly from 32.3% (2012) to 78.

Health Outcomes 50 Years After Preterm Birth in Participants of a Trial of Antenatal Betamethasone.

Background And Objectives: Preterm birth results in neonatal and childhood morbidity and mortality. Additionally, population-based studies show poorer cardiovascular health in adult survivors, but a full range of health outcomes has not been investigated into midlife. We aimed to assess the health outcomes after preterm vs term birth at 50 years in survivors of a randomized trial of antenatal betamethasone.

Associations between growth and childhood body composition in very preterm, late preterm and term children.

Aim: To determine how gestational age at birth and postnatal growth relate to body composition in childhood.

Methods: We calculated conditional growth (birth-2 years, 2 years-6 years) and measured body composition at 2 and 6 years using bioelectrical impedance in cohorts of New Zealand children born very preterm (VPT; 23-31 weeks), late preterm (LPT; 35- <37 weeks) and term (≥37 weeks). We explored the relationships between growth and fat mass (FM) index and fat-free mass (FFM) index at 6 years using multivariable linear regression.
