The ERC Consolidator WELL-BEING project, led by Prof. Meike Bartels, aimed to transform our understanding of human well-being by bridging disciplinary boundaries and integrating insights from genetics, epigenetics, and environmental sciences. It addressed a critical issue: how biological and environmental factors interact to shape individual and societal well-being—a question of growing urgency as mental health and subjective quality of life gain traction in public policy.
The central challenge was the fragmented nature of existing research, which often treats genetic and environmental influences in isolation. For society, this gap limits the design of effective interventions and policies grounded in a holistic understanding of well-being across life stages and social contexts.
The project set four key objectives:
1. Define the well-being exposome by identifying and integrating static and dynamic environmental and social exposures.
2. Uncover the interplay between genome, epigenome, and exposome using polygenic scoring, structural equation modeling, and multivariate GWAS.
3. Develop a comprehensive framework for well-being by integrating multidisciplinary findings across datasets.
4. Innovate data collection through ecological momentary assessment (EMA), GPS/GIS, and social media text mining (SMTM) to capture real-time, context-sensitive data.
The project’s conclusions yielded major scientific and societal contributions. It introduced data-driven methods like Environment-Wide Association Studies (EnWAS) and Poly-Environmental Scores (PES), showing that subjective perceptions—e.g. perceived neighborhood safety—can influence well-being more than objective conditions. Over 300 genetic variants were identified as associated with well-being, and analyses demonstrated that genetic influence on well-being changes across the lifespan and differs partly from that on depressive symptoms.
In the final phase, advanced machine learning models were developed to predict well-being using psychosocial and neighborhood factors. These confirmed that environmental and psychosocial variables are stronger predictors than genetic data. Additionally, the COVID-19 pandemic provided an unforeseen opportunity to examine how well-being determinants shift under crisis, showing increased environmental and reduced genetic influence. Through methodological innovation, interdisciplinary integration, and real-world application, the WELL-BEING project significantly advanced the field and laid a foundation for future policy and research to enhance human flourishing.
