“…Rosenberg, Garbers, Lipkind and Chiasson (2005), and, James-Todd et al (2014) found that chronic and gestational diabetes were significant risks for preterm births. Maternal age remains a risk factor as women older than 35 have more preterm births (Yang, Greenland, & Flanders, 2006;Fuchs, Monet, Audibert, & Chaillet, 2014). Prior preterm births increase the risk for subsequent preterm deliveries, and depending on the population, could vary between 1.5 to 4-fold (Iams & Berghella, 2010, p. 91) A maternal BMI score above 19.8 kg/m2 is protective (Iams & Berghella, 2010, p. 91).…”
