Copeptin levels in adulthood are unknown.<h4>Methods</h4>In this case-control study of 101 adults born very preterm (<30 weeks of gestation) and 105 control adults born full-term, a comprehensive clinical and biological assessment was performed, including blood pressure measurements, kidney ultrasound and determination of plasma copeptin, renin activity, angiotensin II, aldosterone, apelin, sodium and potassium, serum and morning urine osmolality.<h4>Results</h4>The median age in the study was 23.1 years [interquartile range (IQR) 21.2-24.8] and 57% were females.
