BackgroundEvidence for Better Lives Study (EBLS) is an endeavour to establish a global birth cohort with participants from resource poor settings across the globe. It aims to investigate mediators and moderators of child development and wellbeing; it envisages informing policy and practice change to promote child health and wellbeing globally. Pakistan is one of the resource poor settings taking part in this global birth cohort; we report the feasibility of establishing such a birth cohort in Pakistan.MethodFrom March 2019 to July 2019, 153 third trimester pregnant women were identified, using community health worker registers, and approached for baseline demographics and a number of maternal wellbeing, mental health, support related information and stress related biomarkers in a peri-urban area of Islamabad Capital Territory. From October 2019 to December 2019, we re-contacted and followed 121 between 8-24 weeks postnatal period. All interviews were done after consent and data was collected electronically. Results150 (98%) third trimester pregnant women consented and were interviewed, 111 (74%) provided bio-samples and 121 (80.6%) were followed up postnatally. Their mean age and years of schooling was 27.29 (5.18) and 7.77 (4.79) respectively. Majority (82.3%) of the participants were housewives. Nearly a tenth were first time mothers while 63% of women reported current pregnancy to have been unplanned. Overall wellbeing and mental health were reported to be poor (WHO-5 mean scores 49.41 (32.20) & PHQ-9 mean scores 8.23 (7.0)). About 22% of women reported four or more adverse childhood experiences; 12.2% reported intimate partner violence during their current pregnancy. During the postnatal follow up visits, 58% of the women reported breastfeeding their infants. ConclusionThe study demonstrated Pakistan site could identify, approach, interview and follow up women and children postnatally, with a high response rates for both the follow up visits and bio-samples. Thus, a larger scale pregnancy birth cohort study in Pakistan is feasible to conduct.
