“…Sex differences have been studied and documented for many health problems, including heart disease (Azad, Kathiravelu, Minoosepeher, Hebert, & Fergusson, 2011;Claassen, Sybrandy, Appelman, & Asselbergs, 2012;Lawton, 2011), hypertension (Beigh & Jain, 2012;Mounier-Vehier et al, 2012), diabetes (Sekerija et al, 2012), autoimmune disease (Oertelt-Prigione, 2012;Quintero, Amador-Patarroyo, Montoya-Ortiz, Rojas-Villarraga, & Anaya, 2012) and Alzheimer's disease (Sinforiani et al, 2010). The majority of studies of gender roles and norms and their impact on specific health conditions have been generally limited to reproductive health, domestic violence and mental health (Boileau et al, 2008;Collins, von Unger, & Armbrister, 2008;Ghanotakis, Peacock, & Wilcher, 2012;Kerrigan, Andrrinopoulos, Chung, Glass, & Ellen, 2008;Mantell et al, 2009;Paek, Lee, Salmon, & Witte, 2008;Phillips & Phillips, 2010;Wagner, Yates, & Walcott, 2012;Zuo et al, 2012). Less is known about the impact of gender on health behaviors, specifically in the area of obesity and lifestyle factors that influence healthy weight, such as diet (Costanzo, Musante, Friedman, Kern, & Tomlinson, 1999;Fagerli & Wandel, 1999;Frank et al, 2009;Gavin, Fox, & Grandy, 2011;Gray, Cinciripini, & Cinciripini, 1995) and physical activity (Butt, Weinberg, Breckon, & Claytor, 2011;Frank et al, 2009;Gavin et al, 2011;Langer et al, 2009;McLaren, Godley, & MacNairn, 2009;Sjogren, Hansson, & Stjernberg, 2011;…”
