Sociodemographic characteristics and childhood trauma (table 1)
Being single was associated with early PPD (OR=1.9, 95% CI 1.0-3.4,
p=.043), whereas being unemployed was associated with late PPD (OR=1.9,
95% CI 1.2-3.0, p=.004). Age and educational level were not associated
with early or late PPD.
Childhood trauma was twice as common in women with early and late PPD as
in women without perinatal depression (aOR=2.2, 95%CI 1.5-3.2,
p<.001 and aOR=2.1, 95%CI 1.4-3.0, p<.001
respectively). Regarding the different types of childhood trauma, sexual
abuse and emotional neglect were both associated with early (aOR=2.6,
95%CI 1.4-4.8, p<.002 and aOR=2.2, 95%CI 1.4-3.3,
p<.001) and late PPD (aOR=2.5, 95%CI 1.3-4.8, p=.005 and
aOR=1.9, 95%CI 1.1-3.0, p<.012), while physical and emotional
abuse were associated only with late PPD (aOR=2.8, 95%CI 1.4-5.5,
p=.004 and aOR=3.1, 95%CI 1.8-5.3, p<.001).
