Social inequalities in ageing. Copenhagen Life Course Epidemiology in Aging Research (CLEAR)

Our purpose is to study social inequalities in health and aging in a life course perspective, and to explore the pathways through and interactions with psychosocial, psychological and biological factors. We want to inform policy makers on intervention possibilities aiming at reducing social inequality in health among middle-aged and older adults.

To inform intervention strategies a better understanding of life course social determinants of aging as well as their interplay with psychological, behavioural and biological factors is of huge importance in today’s aging society. Knowledge about risk factors and development of interventions in the most vulnerable older citizens will add important new knowledge to this area.




















AHEAD is an acronym for Arbejdsmiljø, Hovedpine og Evnen til at Arbejde i Danmark (Working environment, Headache and the Ability to Work in Denmark)

Headache disorders are the most prevalent neurological disorders, and among primary headaches migraine and tension-type headache are the most frequent. Among occupationally active individuals in Denmark, 10% of the men and 24% of the women report migraine or frequent headache.

Despite the high number of people with headache disorders, surprisingly few studies have investigated the causes and consequences of headache in an occupational health perspective. Consequently, the adverse effects of headache on sickness absence, work ability and—not least—quality of life are often unnoticed.

Together with our collaborators, we are investigating causes and consequences of headache, and how these consequences can be mitigated among employees in Denmark.

Currently, with support from Helsefonden we are studying the demand-specific work ability among people with from migraine or frequent headache and among people with possible medication-overuse headache.

The overall aim of our research is to investigate the effect of the COVID-19 pandemic on emotional reactions to the pandemic, social relations at work, and social stigmatization among frontline employees.

Currently, we are investigating teachers at public schools and employees, working within eldercare, ambulance service, psychiatry, childcare, and rehabilitation.


This research is carried out as a collaboration between researchers at the Section of Social Medicine, Department of Public Health, University of Copenhagen and labor unions (FOA and Danmarks Lærerforening).
