Linear regression analyses were performed to examine the association between DST variables and body composition. Model 1 was adjusted for no covariate (N = 77); model 2 was adjusted for sex and the mean personal environmental temperature over the L10 period (personal-ETL10, n = 76). Nonstandardized B coefficient, adjusted R2, and p values are provided. Significant values are shown in bold (p ≤ 0.05). BMI = body mass index; FMI = fat mass index; IS = interday stability; IV = intraday variability; L10 = mean of the 10 consecutive hours with the lowest values and when they occurred (TL10); LMI = lean mass index; M5 = mean of the 5 consecutive hours with the highest values and when they occurred (TM5); RA = relative amplitude; VAT = visceral adipose tissue.
