BMI = body mass index, WC = waist circumference.
a
All values are unadjusted values. Difference = self-reported value − measured value.
b
Time difference from self-report to measurement.
c
Self-reported weight value was missing for one woman, and self-reported waist value was missing for one man and one woman.
