Clinical characteristics at study assessment in young adulthood.

aHeight SDS by Finnish growth charts.
bTarget height SDS reflects the expected adult height of the individual based on genetic growth potential. It was calculated from the equation: 0.0611×father's height (cm)+0.0703×mother's height (cm) − 22.1 [19].
cNumbers represent geometric means (and geometric SDs) for the intakes, weight, and BMI; and means (and SD) or n (%) for the other variables. Geometric SD corresponds to relative increase in the variable corresponding to 1 SD-unit absolute increase in the logarithm of the variable. Number of participants not providing valid data were 13 on both parents' heights, eight on exercise habits, and 86 on food-diary data. p-Values are for the difference between the VLBW and term-born groups (Student's t-test or Pearson's chi-squared test).
