UFC, 24-hr urinary free cortisol excretion (μg); aBMD, areal bone mineral density (g/cm²); BMC, bone mineral content (g); area, bone area (cm²). Data are presented as Pearson’s (R) and partial (Rp) coefficients adjusting for variables identified as cofounders in univariate analyses. Exact n varied by comparison as cases were excluded pairwise.

Correlation approaches significance at p<0.10. Correlation is significant at:

p<0.05,

p<0.01,

^***

p<0.001.

Model 1: Adjusted for 24-hr urine volume (L). Model 2: Partial correlations adjusting for 24-hr urine volume, height, lean mass, ethnicity and previous duration of oral contraceptive use (zero for non-users). Model 3: Partial correlations adjusting for 24-hr urine volume, height, lean mass, ethnicity, previous duration of oral contraceptive use, sport activity, calcium/kcal intake and Perceived Stress Scale score.
