These findings were consistent with studies that children from high SES family have bigger physiques than those from low SES family (Morton, et al, 2002;McBride, 1990;Mahoney, Kaiser et al, 1999;McLoyd, 1998;Ma, Wu, Yang, 2010;NICHD Early Child Care Research Network, 1998;Ortega, Fang, Perez, et al, 2007;Parke, Coltrane, Duffy, Buriel, Dennis et al, 2004;Rona, Chinn, 1991;Solinger, 1999;Mohanty, Woolhandler, Himmelstein, Pati, Carrasquillo, Bor, 2005;Slesinger, Christenson, Cautley, 1986;Stamatakis, Wardle, Cole, 2010). Finally, by the ANCOVA in which both socioeconomic factors and groups were taken as independent variables and age was taken as a covariate, although strong associations between physiques and group were identified, there were hardly associations between socioeconomic factors and physiques.…”
