Target Child

The current design follows pregnant women, the children they subsequently birth (what we refer to as the target child, or the prenatal cohort), a subsample of husbands, and a subsample of one existing child between the ages of 36 and 60 months at the time of recruitment, if present (what we refer to as the older sibling, or the early years cohort). Pregnant women are recruited from the population of forcibly displaced Rohingya living in the refugee camps (N=2250), Bangladesh, and a subsample from the surrounding host community (N=550). In the current and confirmed design, there will be a total of three or four waves of data collection for each household over the period that spans recruitment (during pregnancy) through to the target child reaching 6-months of age. In between, data is collected at the third trimester (for women recruited before that) and 72 hours and 28 days after birth. A 24-month wave is currently in the planning stages. A 24-month wave will include measures of child growth and neurocognitive development, and extensive caregiver surveys.

This study takes a particular interest in adolescent mothers, as a highly understudied population, because we know that children born to adolescent mothers tend to have poorer developmental outcomes and are more likely to bear children early, perpetuating an intergenerational cycle of poor developmental outcomes. Despite strong evidence of the risks and intergenerational consequences of early childbearing, there is remarkably little evidence on how to support pregnant and parenting adolescents. This study will explore risk and protective factors that can serve to design new and improve existing interventions.

RECRUITMENT

The children born to recruited pregnant women, the Prenatal Cohort, are our primary research interest. It is their development, ultimately, that we are trying to understand, focused on what factors pose risks to their development, and what sources of resilience could be leveraged to improve their developmental odds. They have not themselves been exposed to war. Their exposure is limited to the trauma and mental health problems their parents endure, even several years after arriving in Bangladesh, and the ongoing instability and unpredictability of the camp context. Prenatally their development is being shaped and primed through biological mechanisms related to their mother’s experiences and wellbeing, and postnatally through caregiving, and the environments that affect caregiving relationships, such as the larger family or household unit, and the community.

RECRUITMENT

When recruiting pregnant women into the study, we ask them about existing children who fall into the age range of 36-60 months. These children, with their caregivers’ consent, will then be invited to participate in additional data collection activities focused on their development. A total of nearly 500 women had children in this age group and were willing to participate. These children make up our “Early Years Cohort”. Tracking the developmental trajectories of older siblings allows us to investigate 1) how the same exogenous events may affect children differently depending on their developmental stage at the time of the event; and 2) differential trajectories based on how close to displacement children were gestated, born, and raised.

Target Child

Increasing evidence, mainly from high-income countries, points to the importance of fathers’ involvement in early care and parenting for children’s socioemotional and cognitive development. We recruit a sample of husbands (N=800), stratified by whether or not their wives are first-time mothers and, if not, whether or not they have older children in the Early Years cohort. Stress, trauma, and mental health problems are known to affect husbands’ and fathers’ behaviors toward their families. Father’s mental health with regards to ECD has not, however, been the focus of much attention, especially in humanitarian contexts. This is a major gap in the literature, especially in light of the strong and growing evidence about the importance of fathers’ engagement on children’s development.
