“…An inverse dose-dependent association has been shown, suggesting that longer duration of breastfeeding is associated with a lower body mass index (Arenz et al, 2004;Harder et al, 2005). Some studies have also suggested that early weaning may increase body mass index in childhood, but results are inconsistent (Forsyth et al, 1993;Wilson et al, 1998;Morgan et al, 2004;Wright et al, 2004). Body mass index provides only information about body weight, whereas it does not distinguish between fat and lean mass (Nevill et al, 2006;Wells and Fewtrell, 2006).…”
