Differences in frequency, total time, total volume and energy expenditure of different physical activity subtypes between unimpaired preterm-born VLBW and term-born control young adults.

VLBW = very low birth weight (aMET×hours of physical activity/year (MET = metabolic equivalents; ratio of metabolic rate during exercise and estimated metabolic rate at rest; 1 MET corresponds energy expenditure of approximately 1 kcal/kg×hour).bphysical activity with MET ≥5.cPModel 1; adjusted for age and sex.Model 2; adjusted for age, sex and body mass index.Model 3; adjusted for age, sex, body mass index, daily smoking of the participant, and highest education of either parent.Predicted by linear regression and adjusted for covariates in different models.
