Cohort Profile: Perinatal depression and child socioemotional development; the Bachpan cohort study from rural Pakistan

PURPOSE: This is a prospective pregnancy–birth cohort designed to investigate the effects of depression on socioemotional development of children. Perinatal depression is a risk factor for poor child development and for many it has a recurring chronic course. Thus, the exposure to depression can continue through the early years of the child with detrimental developmental outcomes. PARTICIPANTS: Between October 2014 and February 2016, we recruited 1154 pregnant women from a rural subdistrict of Pakistan. Data include longitudinal and repeated measures of maternal psychosocial measures and child growth, cognitive and socioemotional measures. Follow-up include mother–child dyad assessments at 3rd, 6th, 12th, 24th and 36th months of child age. All these follow-ups are community based at the household level. We have competed baseline assessment. FINDINGS TO DATE: Of the eligible dyads, we followed 885 (76.6%), 929 (91%) and 940 (93.3%) at 3, 6 and 12 months post-childbirth. We include a subsample mother–child dyad DNA and inflammatory biomarkers, 73 and 104, respectively. FUTURE PLANS: While we continue to do 24-month and 36-month follow-up assessments, we plan to follow these mother–child dyads up to the age of 7–8 years with some children being exposed to at least 1 year of school environment.
