The ESTER study focuses on preterm birth at any gestational age and maternal hypertension in pregnancy and gestational diabetes as exposures. The study comprises 1161 subjects born in the two northernmost provinces of Finland in 1985-1989 and included two arms; the ESTER preterm birth arm includes 396 participants born preterm (55 VLBW) and 356 controls (a random sample of those born at term in the source population). Subjects born in 1985-1986 were recruited through the Northern Finland Birth Cohort 1986 and the remaining subjects were identified through the Finnish Medical Birth Register. In 2009-2012, all subjects underwent a clinical examination.
Our results are consistent with a dose-response relationship between degree of prematurity and metabolic syndrome, ambulatory blood pressure and its variability and physical fitness.

ESTER Cohort
The ESTER cohort is a population based cohort from Northern Finland. Participants were recruited between 1985 and 1989 either via the Northern Finland Birth Cohort 1986 (NFBC) for those born 1985-1986, or were born in the same geographical area in 1987-1989 and identified through the Finnish Medical Birth Register.
