The Bavarian Longitudinal Study follows the lives of a cohort of babies born in Bavaria between 1 January 1985 and 31 March 1986. In 2025 this groundbreaking research (the longest longitudinal study of its kind) marks its 40th anniversary. Special thanks go to all those participants and researchers whose continued commitment has made this work possible.


The Bavarian Longitudinal Study is a unique long-term research project which has followed participants for over 40 years from birth into adulthood. Through regular collection of health data, interviews and brain scans we aim to understand how early childhood, particularly very early birth or very low birth weight, affects development, relationships and health throughout life.
Our findings help scientists and doctors worldwide to better support children and adults, ensuring that future generations grow up healthy and successful. We are deeply grateful to our participants for their incredible commitment over the decades - you make this research possible.
Hundreds of participants have taken part over the decades. Their commitment has made this research possible.
40 years of sustained effort and dedication lie behind the data and discoveries.
Individuals born at different stages of pregnancy and in diverse family circumstances have been studied to discover how these early factors shape lifelong development.
Dissemination of knowledge worldwide will enable future generations to grow up healthy and supported.
Influence of social and genetic factors on lifelong health.
Use of brain scans and new imaging techniques to better understand brain growth and changes.
Researching how friendships, family ties and mental health develop and are influenced over time.
The trajectory from birth to old age. Which early experiences slow down or accelerate aging and shape health and resilience.
