More than 100,000 pregnant women and their partners across the UK will be invited to join a new birth cohort study that tracks the same babies from pregnancy through childhood and into adult life. This matters because scientists still do not fully understand how a child’s earliest social, emotional, and physical environment—combined with their biology—shapes their long-term health, development, and risk of disease. Existing British cohort studies have already revealed how early-life conditions influence later outcomes, but society has changed: family structures, diets, digital exposure, and environmental pressures are different today. This study will capture those new realities. If successful, the Life Study will create a detailed, anonymised dataset that researchers, policymakers, and public health officials can mine for decades. It could identify which aspects of a child’s early environment protect against later illness or developmental problems, and which increase vulnerability. The findings may inform parenting programmes, school readiness initiatives, healthcare screening, and social policy—helping children from all backgrounds get a better start in life.
View original technical description
A birth cohort study follows the same babies throughout their lives to understand more about how a child's very early social, emotional and physical development and their family and wider environment influences their future development, health and wellbeing as well as their risk of future ill health. These special types of studies give insights into what is called the life course starting in early life - they are a unique and special way to find out how early life experiences matter for later childhood and adult life. Our study will help identify what aspects of the environment in its broadest sense protect children and maximise their life chances and the ways in which that protection operates. It will also help us understand what aspects may increase vulnerability. We wish to understand the interplay between environmental and biological influences in early life recognising that this needs understanding of parents' lives and the wider family and society too. We will invite more than 100,000 pregnant women and their partners from across the UK to join our study. We want to include women and their partners from all walks of life. We will work to maximise recruitment of people from different ethnic groups. In pregnancy both parents will be interviewed, weighed and measured and asked to take part in some simple computer based tests. Parents will be asked to bring their baby to be seen at 6 and 12 months of age for some body size measurements and eye and child development tests. There will be no blood tests for the baby. We hope to follow all the children and their families throughout childhood and adult life so that we can see how they grow and develop and how their family circumstances change. We will do that in a number of ways including by getting consent at the beginning of the study to link to future routine health and other records of the baby and the parent. Scientists and others learn a lot from these large studies about how we can help children get a good start in life and improve their life chances and future well being and happiness. The information collected will be anonymised and made available to researchers to analyse to make sure we get the most benefit from it. We will be able to compare the Life Study generation with information collected from earlier generations in similar special British cohort studies. We will make sure that families taking part are informed about the progress of the study and any early findings and will ensure that other scientists, in the UK and abroad, policymakers and all members of the public also get to hear about Life Study findings.
