2.5. Assessment of Body Weight and Body Composition
CREST
All variables were measured at baseline and month 12. Body weight was assessed without shoes, in light clothing, using a digital scale at the research center. Body composition (fat mass, lean mass, and visceral fat ass) was measured using dual X-ray absorptiometry (iDXA, GE). Waist circumference was measured using a measuring tape midway between the lowest rib and the iliac crest by trained study personnel.
