^aLong-term (40 year) weight change was determined between the index examination (2011–2014) and enrollment (1971–1974) and expressed as a percentage of the weight at the index examination.

^bRecent (6 year) weight change was determined between the index examination and the preceding clinic visit (2005–2008) and expressed as a percentage of the weight at the preceding clinic visit.

^cThe sample includes 1,361 individuals with HR-pQCT measures at the tibia (N=1,328) and/or radius (N=1,263).

^dClinical characteristics were assessed at index examination (2011–2014) unless otherwise noted.

^eThe baseline examination was at enrollment (1971–1974) for long-term weight change and at the preceding clinic visit (2005–2008) for recent weight change.
