Lay summary
The Pacific Islands Families (PIF) birth cohort study is a successful and unique longitudinal investigation of Pacific infants born in South Auckland, Aotearoa (NZ) in 2000 (n=1398). Information from children and their families has been collected across 10 measurement waves from 6 weeks till 23 years, with findings widely disseminated and translated to policy and practice. Building on 23 years of investment, PIF: Ala mo Tupulaga Pasifika (PIF: ATP) is a unique epidemiologically robust 5-year research programme focused on determining the pathways supporting thriving, resilient, outcomes as these young Pasifika adults and their families negotiate critical lifecourse transitions. Culturally specific longitudinal research is essential to identify antecedent resilience and risk factors for developmental trajectories through the lifecourse, and to drive effective policies and programmes that serve the needs of Pacific families, promote wellbeing, and address social disparities.
