Design outcomes

Primary

MeasureTime frame
1. Total-body less-head (TBLH) Bone Mineral Content (BMC) for lean mass adjusted-for-height (TBLH-BMCLBM) Z-scores) measured using DXA (dual-energy X-ray absorptiometer) at baseline and one year 2. Lumbar spine (LS) Bone Mineral Apparent Density (BMAD) (LS BMAD) Z-score measured using DXA at baseline and one year

Secondary

MeasureTime frame
1.1 Prevalence of low muscle function; grip strength (Z-score 2 years) explains changes in these bone and muscle outcomes measured using hand x-ray (to measure bone age) and questionnaire (to measure chronological age) at baseline and one year
