Childhood Adversity Raises Early Death Risk More Than Sevenfold

In brief
- Children with both health-related adversity and high family adversity had more than 7x the risk of dying from age 16 into early adulthood.
- The study followed 1.2 million Danes born between 1980 and 2001 until 2022 (ages ~16–42).
- 26% of the most disadvantaged children had a childhood mental health diagnosis versus 7% of the least disadvantaged.
- The doubly burdened group with amplified mortality risk represented 1.4% of the study population.
- The study was published in The Lancet Regional Health – Europe (2026), DOI: 10.1016/j.lanepe.2026.101863.
Children who face both health problems and severe family hardship run more than seven times the risk of dying between age 16 and early adulthood compared with children who grow up with few or no such challenges. That is the central finding of a new study from the University of Copenhagen, published in The Lancet Regional Health – Europe.
The result comes from registry data covering 1.2 million Danes born between 1980 and 2001, whom researchers followed until 2022, until death, or until emigration — a span of roughly ages 16 to 42.
"This is a striking figure in a society that prides itself on providing universal access to health care," said Naja Hulvej Rod, professor of epidemiology at the Copenhagen Health Complexity Center and lead author of the study. "Yet here we see a group of children who are profoundly disadvantaged and who continue to experience the consequences of health inequality many years later."
What counts as adversity?
The researchers measured hardship at three distinct levels of a child's life:
- Individual level: birth-related factors such as preterm birth, plus physical and mental health indicators, including psychiatric diagnoses and frequent hospital contacts.
- Family level: poverty, long-term unemployment, serious illness, death, mental illness, and alcohol or substance misuse within the family.
- Neighborhood level: local-area data on income, education, and unemployment where the child grew up.
Epidemiology is the study of how often diseases and other health conditions occur in groups of people, and why. Adversity, in this study, means any of these measurable hardships — from a psychiatric diagnosis in childhood to a parent's long-term unemployment.
How do these hardships combine?
The team examined how different adversities cluster together and how they relate to mortality from age 16 onward.
They found that children with the highest levels of family adversity were also the most likely to face health problems of their own. In the most disadvantaged group, 26% had received a mental health diagnosis during childhood, compared with 7% in the least disadvantaged group. Those children were also more likely to grow up in disadvantaged neighborhoods: 28% versus 16%.
Each of the three forms of adversity — individual, family, and neighborhood — was independently associated with a higher risk of death in early adulthood.
But the key finding involves overlap. Children facing both health-related adversity and extensive family adversity showed mortality beyond what the individual effects of each hardship would predict. This doubly burdened group made up 1.4% of the study population.
"In some cases, adversities across different aspects of a child's life appear to reinforce one another and amplify the risk of premature death," Rod said. "This likely reflects a situation in which some children are exposed to multiple interconnected challenges from an early age, making them especially vulnerable."
What can't the data capture?
The study is observational. It identifies patterns in registry data, not proof that adversity directly causes early death.
Rod acknowledged that the measured factors may not tell the whole story. "The excess mortality we observe is likely related both to the adversities we measure and to other factors that are not captured in our data, such as air pollution, bullying or neglect," she said. "One interpretation is that the most disadvantaged children are more likely to experience an accumulation of adverse circumstances simultaneously."
Denmark's registries are unusually comprehensive, which strengthens the study. Still, unmeasured hardships could explain part of the elevated risk, and the findings may not transfer directly to countries with different welfare and health systems.
What should prevention look like?
The researchers argue the findings call for rethinking how societies reduce health inequalities.
"We need to consider the child's overall life situation and take a broader approach to prevention than focusing on a single illness or a single type of adversity," Rod said.
"If we want to reduce health inequalities, we cannot focus solely on treating problems once they emerge. We also need to become better at identifying children and families facing multiple forms of adversity and ensure that they receive coordinated support across health care, social services and other welfare sectors."
In practical terms, that means health care, social services, and other welfare institutions would need to share responsibility for children who appear repeatedly in the system — the child hospitalized many times who also lives amid poverty or substance misuse at home.
