“…For example, different equations have been established for predicting stature from knee height in white and black populations (Chunlea and Guo, 1992), Japanese (Myers et al, 1994;Knous and Arisawa, 2002), Hispanics (Palloni and Guend, 2005) and Thai people (Cheng et al, 2001). As ulna length-height relationships have also been established in different populations in different ways, care should be taken about extrapolation from children (Valk, 1971;Cheng et al, 1998;Gauld et al, 2004;Smith, 2007) to adults (Elia M (chairman & editor), 2003;Agnihotri et al, 2009;Auyeung et al, 2009), and vice versa, between different ethnic groups, (Joshi et al, 1964;Elia M (chairman & editor), 2003;Gauld et al, 2004;Auyeung et al, 2009), between different measurement techniques (Munoz et al, 2001;Elia M (chairman & editor), 2003;Gauld et al, 2004;Zhou et al, 2007) and between healthy subjects and those with marked osteoporosis or scoliosis. In one study involving community dwelling older Chinese (65-98 years) attending an osteoporosis centre, predictions of height based on ulna length was found to be comparable to that obtained from fibula length.…”
