“…Numerous factors that influence a pregnancy and its subsequent outcome have been identified, including illness (Atta et al, 2016;Ellington et al, 2011;Guntupalli, Hall, Karnad, Bandi, & Belfort, 2015;Hartert et al, 2003;Lapinsky, 2010;Mouyis, Thornton, Williams, & Giles, 2017;O'Brien et al, 2014), stress (Carmichael & Shaw, 2000;Christian, 2014;Coussons-Read, Okun, & Nettles, 2007;Davis, Glynn, Waffarn, & Sandman, 2011;Livingston, Otado, & Warren, 2003;Rini, Dunkel-Schetter, Wadhwa, & Sandman, 1999;Sandman, Wadhwa, Chicz-Demet, Dunkel-Schetter, & Porto, 1997), emotional states such as depression and anxiety (Abedian, Soltani, Mokhber, & Esmaily, 2015;Diego et al, 2004;Lewis, Austin, Knapp, Vaiano, & Galbally, 2015;Orr, James, & Blackmore, 2002), and disturbed sleep (Lee, 2006;Okun, Hall, & Coussons-Read, 2007;Okun, Hanusa, Hall, & Wisner, 2009;Okun, Schetter, & Glynn, 2011;Tomfohr, Buliga, Letourneau, Campbell, & Giesbrecht, 2015).
