Social inequality in aging in the Lund Group

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.

Social inequality in aging in the Lund Group

Research focus

Professor Rikke Lund is leading the Copenhagen Lifecourse Epidemiology in Ageing Research group (CLEAR) with four major research themes:

  1. Life course and aging – with a main focus on identification of life course social, psychological, behavioural and biological risk factors for physical and cognitive function, inflammation and retirement patterns in late middle-age and early old age.

  2. Risk factors for disease and functional decline among older people – with a main focus on the impact of social circumstances and risk of functional decline.

  3. Natural experiments and complex interventions - with a main focus on middle-aged and older people living in socially diverse neighbourhoods.

  4. Demography of aging – with a major focus on gender and social inequalities in health and life expectancy.

We believe that 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, in order to inform effective intervention strategies. Specific knowledge about risk factors and development of interventions in the most vulnerable older citizens will add important new knowledge to this area.

Main findings

Recent findings include:

  • Adverse socio-economic position across the life course (parental socioeconomic position and own income history) is associated with poorer physical and cognitive function as well as higher inflammatory levels in midlife.

  • That older Danish adults are in higher risk of decline in physical function and increased mortality when exposed to both poor social relations and low level of financial assets compared to those with good social relations and high assets. Poorer physical function was associated with a greater increase in general practitioner use among males, those who were married, and those with high financial assets.

  • Experiencing conflicts and demands from close social relations is associated with increased 10-year risk of hospitalization with ischemic heart disease and higher 11-year mortality in middle-aged Danes. The effect is significantly stronger in low socioeconomic groups.
