Impact of Extreme Prematurity or Extreme Low Birthweight on Young Adult Health and Well-being

Project Details

We are assessing physical, socio-emotional and mental health of extremely preterm (EP, <28 weeks’ gestation) or extremely low birthweight (ELBW, <1000 g) young adults born in the era after surfactant was introduced into clinical practice.

The participants comprise the Victorian Infant Collaborative Study 1991-92 (VICS 91-92) cohort, a unique geographic cohort of all (n=297) EP/ELBW infants survivors born in the state of Victoria in 1991-92, and 262 contemporaneously recruited matched NBW controls. A wealth of perinatal information, and data from longitudinal follow up at ages 2, 5, 8 and 18 years are already available.

VICS research is one of Australia’s flagship research areas since the 1980s, with over 50 publications on the long-term outcomes of very tiny or preterm infants in Victoria since that time .
