Srikanthan P, Horwich TB, Press MC, et al. - Researchers utilized the National Health and Nutrition Examination Survey 1999–2004 to investigate if variations in body composition add to gender disparities in cardiovascular disease (CVD) mortality, and for this purpose, they examined the link between components of body composition and CVD mortality in healthy males and females. They found that both men and women exhibited lower CVD and mortality in relation to higher muscle mass. However, high fat in females, irrespective of muscle mass level, seemed to be related to lower CVD mortality risk. This observation not only shows that muscle mass has importance for CVD risk prevention in healthy males and females but also suggests sexual dimorphism regarding the CVD risk related to fat mass.
