2021 - Ongoing

COINCIDE is a prospective, longitudinal study of children aged 0 to 9 years living in diverse settings of North and South India to evaluate the independent, cumulative, and interaction effects of nutritional, psychosocial, and environmental determinants of neurodevelopment and child mental health in LMICs. The study also aims to identify the processes by which these determinants are influenced by sociodemographic and economic disparities to result in differential child outcomes.


There is a need to extend our focus on the determinants of ECD beyond the first 1000 days to better identify the sensitive periods of each determinant. More prospective, longitudinal studies are needed to quantify the associations between early life experiences with later mental health outcomes, as an attempt to determine the aetiologies and progression of common mental health disorders.
