“…It is well known that inadequate weight gain as well as excessive weight during pregnancy has a profound negative impact on maternal and newborn health (Crane et al 2009, Choi et al 2011, Chung et al 2013, Drehmer et al 2013) and may reduce in this way female reproductive success dramatically. Inadequate gestational weight gain mainly results in small for gestational age newborns (Johansson et al 2007, Kiel et al 2007, Han et al 2011, Jeric et al 2013, and consequently with increased newborn morbidity and mortality (Savitz et al 2011). Excessive gestational weight gain in contrast, has been associated with increased rates of pregnancy complications such as large for gestational age newborns, preeclampsia, gestational diabetes, gestational hypertension, increased rates of caesarean sections, but also long term effects such as increased rates of obesity among mothers and offspring (Rössner 1997, Gunderson & Abrams 2000, Kac et al 2004, Cedergren 2006, Kabali & Werler 2007, Wrotinak et al 2008, Chung et al 2013, Hill et al 2013.…”
