“…Notably, 10 statistically significant associations were found between PPD symptoms and risk factors reported only once across studies. These included physical abuse (d=0.54, medium ES), sexual abuse (d=1.57, large ES) (Gilson & Lancaster, 2008), anxiety up to three years prior to birth (T-3 Anxiety: r=0.16, small ES; T-2 Anxiety: r=0.27 medium ES; T-1 Anxiety: r=0.37, medium ES), (Hipwell et al, 2016b), and grandmother acceptance during childhood (r=-0.33, medium ES) (Leadbeater & Linares, 1992). Further significant associations included multiple stressors (OR= 9.50, large ES), drinking alcohol or smoking prior to pregnancy (prior alcohol: OR 2.04, small ES; prior smoking: OR=2.01 small ES) or during the third trimester (alcohol: OR=2.95 small-medium ES; smoking: OR=2.06, small ES) (Nunes & Phipps, 2013), low self-esteem (r=-0.43, medium ES) (Secco, 1997), acculturative stress (r=0.32, medium ES) and enculturative stress (r=0.22, small ES) (Zeiders et al, 2015).…”
