“…The pooled prevalence of PND in fathers was found to be 19.26% (95% CI: 17.32, 21.21) within 3 months after the childbirth, 23,[26][27][28]36 13.64% (95% CI: 12.98, 14.30) between 3 and 6 months 24,25,30 and 18.97% (95% CI: 15.73, 20.21) within 6 months, 33,37 and 20.60% (95% CI: 18.26, 22.93) from birth up to 12 months postpartum. 31,32,34,35 There was a substantial heterogeneity in the studies that were included for PND prevalence estimates between birth and 3 months (I 2 ¼ 99%, p < 0.00001), 3 to 6 months (I 2 ¼ 98%, p < 0.00001), birth to 6 months (I 2 ¼ 78%, p ¼ 0.03), and birth to 12 months postpartum (I 2 ¼ 87%, p < 0.0001). PND was shown to be more prevalent in fathers within the first year after childbirth, with the highest prevalence occurring within 3 months after childbirth.…”
