The Dunedin Multidisciplinary Health and Development Study, renowned globally for its comprehensive exploration of human health and development, is launching its age 52 assessments, according to Otago University. This latest phase targets an often overlooked but pivotal life stage, with Research Professor Moana Theodore, the Study Director, highlighting the critical need to understand midlife health and well-being dynamics.
Why it matters: Focusing primarily on childhood and old age, research has largely bypassed the middle stages of life. The Dunedin Study aims to bridge this knowledge gap, examining how early life influences shape health trajectories and impact aging processes. "Midlife is a time of change... it's also when significant health issues can arise," notes Professor Theodore, stressing the importance of this research phase for addressing healthcare, social, and economic challenges associated with an aging population.
Details:
The study follows 1,037 individuals born in 1972-1973 in Dunedin, offering unparalleled insights into human development.
The age 52 assessments will incorporate a variety of physical tests, including dental, vision, hearing, respiratory examinations, and brain MRI scans.
A focus will also be placed on the environmental impacts on health, exploring participants' exposure to chemical toxins.
Zoom in: The Dunedin Study boasts an impressive 94% participation rate from living members at its last assessment, underscoring the dedication and contribution of its participants. This high retention rate allows for a detailed examination of a broad spectrum of human experiences, setting the study apart from other longitudinal research.
What they're saying: Professor Theodore lauds the Study members as "the true heroes," having dedicated half a century to this research. Their participation has garnered recognition, including Civic Awards and the prestigious Rutherford Medal in 2022. With the last assessments conducted pre-COVID-19, the study now also aims to explore the pandemic's lasting impacts on individuals' lives.
What's next: As the Study enters this new phase, it continues to build on its legacy of informing both national and international health policies and practices. Professor Terrie Moffitt, the Associate Director, emphasises the Study's role as a "trusted source of health information overseas," with findings contributing to the global understanding of health and disease.
Between the lines: The Dunedin Study's unique approach of in-depth, in-person assessments sets a high standard for health research, providing invaluable data on the variation in biological aging and the widespread prevalence of mental health conditions among participants.
The bottom line: By delving into the midlife period, the Dunedin Study seeks to uncover the lifecourse pathways leading to health inequities and inform interventions aimed at promoting health and well-being into older age. This phase represents a pivotal step in understanding how to support a healthy, aging population effectively.
