Syndrome X in 8-y-old Australian children: Stronger associations with current body fatness than with infant size or growth

Abstract

OBJECTIVE: Syndrome X (clustering of insulin resistance, dyslipidaemia and hypertension) in adults with central obesity has been suggested to be a consequence of poor foetal development.
