“…While many studies suggest that secular increases in stature are predominately increases in leg length (Greulich, 1957;Udjus, 1964 as cited in Malina et al, 2004;Dangour et al, 2002;Fredriks et al, 2005;Malina et al, 2004;Meredith, 1978;Moore, 1970;Sanna and Sorro, 2000;Tanner et al, 1982;Vercauteren et al, 1998), results from other studies are not entirely consistent or easily interpreted with available information (Greulich, 1976;Himes, 1979;Kaur and Singh, 1981;Kromeyer-Hauschild and Jaeger, 2000;Leung et al, 1996;Malina et al, 2004;Sanna and Soro, 2000). Several studies have reported gains in mean height but no increases in mean relative leg length in either sex (Greulich, 1976;Kaur and Singh, 1981;Kromeyer-Hauschild and Jaeger, 2000). Others have reported significant increases for males, but not females (Himes, 1979;Malina et al, 2004), and at least one study reports noticeably greater increases in relative leg length among females, but not males (Leung et al, 1996).…”
