Our analyses also did not include several other factors that have been previously shown to relate to neonatal anthropometry, including maternal pregnancy weight gain (Kramer, 1987; Catalano et al, 1995; Goldenberg et al, 1997; Frederick et al, 2008; Roland et al, 2012; Tikellis et al, 2012), maternal and paternal birthweight (Kramer, 1987; Little, 1987; Emanuel et al, 1992; Magnus et al, 2001), maternal micronutrient status (Kramer, 1987; Mathews et al, 1999; Leffelaar et al, 2010), placental weight (Kramer, 1987; Roland et al, 2012; Tikellis et al, 2012) and maternal glucose metabolism before or during pregnancy (Catalano et al, 2003; HAPO Study Cooperative Research Group, 2009; Catalano et al, 2012; Roland et al, 2012). …”
