In the current issue of the Journal of Sport and Health Science,Wang et al.^(1)describe their prospective study,where they analyzed whether or not multiple pregnancies would influence glycemia and the glycemic response to physical exercise in gestational diabetes mellitus(GDM).2 Multiparous women are known to be at a higher risk for GDM than primiparas.GDM carries an increased risk for adverse perinatal outcomes,not only for the mothers but also for the newborn babies.Due to a contemporary environment that is conducive to a sedentary lifestyle and obesity,the incidence of GDM among pregnant women is increasing.
