¹Abbreviations are as follows: Wt weight, ht height, BMI Z age-sex-adjusted BMI z-score, waist circ waist circumference, hip circ hip circumference, SS subscapular skinfold thickness, TR triceps skinfold thickness, BIA bioelectrical impedance. Data from 1110 participants in Project Viva. Some participants did not have data for all forms of measurement, so some correlations were among as few as 873 participants.
