New knowledge aims to prevent social inequality in weight and well-being.
Social inequality is increasingly shaping Danish children's weight, mental health, and overall well-being.
That is why we are supporting a new research project that will investigate the patterns and mechanisms underlying these inequalities and explore how prevention efforts can be targeted more effectively.
The project, called Dynamics, combines machine learning, complex simulation models, and large-scale datasets to develop a deeper understanding of the links between social inequality and challenges related to weight and well-being.
Important for future prevention efforts
The Centre is supporting the project with DKK 6 million. The findings could contribute to earlier and more effective interventions for children and young people in vulnerable circumstances. This is the assessment of Nina Geiker, Programme and Development Director:
“We know that there are clear links between social inequality, weight, and well-being. However, we need a better understanding of what drives these relationships and where interventions can have the greatest impact in reducing them. If Dynamics succeeds in identifying the most likely patterns and dynamics underlying inequality, we will be able to target prevention efforts much more effectively,” says Nina Geiker.
Understanding the mechanisms behind inequality
The project is led by Professor Naja Hulvej Rod together with Assistant Professor Jeroen Uleman and Associate Professor Anne Helby Petersen from the Centre for Complexity and Health at University of Copenhagen. Naja Hulvej Rod explains:
“Research on childhood obesity has long been dominated by a focus on diet and physical activity. Today, however, we know that weight development is also shaped by social conditions, well-being, and mental strain, which can influence and reinforce one another throughout childhood.”
Among other things, Dynamics will investigate the dynamics behind inequality by analysing:
- how social conditions influence children's well-being and weight over time;
- which children are most vulnerable;
- which types of interventions have the greatest potential to reduce inequality effectively.
The researchers will do this by combining Danish register data with advanced analytical methods and artificial intelligence. See the fact box for further details.
The Dynamics Project
- draws on data from more than 2.2 million children born in Denmark between 1980 and 2015
- links this data with information on factors such as weight, well-being, family circumstances, and neighbourhood conditions throughout childhood
- uses, among other methods, causal discovery machine learning, which applies artificial intelligence to identify likely causal relationships within complex datasets. This will help reveal how challenges and influences at the individual, family, and societal levels interact and evolve over time.
The study is being conducted by the Centre for Complexity and Health at the University of Copenhagen and is supported by the Centre for Healthy Living and Well-being.
The project is expected to be completed in 2030.
New figures from the National Institute of Public Health document substantial social inequalities in adolescents' weight and well-being. In some groups, the trend is even worsening.
The report, Trends in Social Inequalities in Adolescent Overweight and Low Mental Health and Well-Being, shows, among other findings, that:
- 17.6% of adolescents from lower socioeconomic groups were overweight or living with obesity in 2022.
- The corresponding figure was 9.0% among adolescents from higher socioeconomic groups.
The gap appears to be widening over time, particularly because these challenges are increasing among the most disadvantaged groups.
The report also highlights significant differences in mental well-being. In 2022:
- 33.4% of adolescents from the lowest socioeconomic group reported low mental well-being.
- The corresponding figure was 19.7% among adolescents from higher socioeconomic groups.
The trend is particularly pronounced among girls from socially disadvantaged families.
The report is based on data from the Health Behaviour in School-aged Children Survey and was supported by the Centre for Healthy Living and Well-being.
