Norwegian Old age Health and Retirement Survey (NORSE)

Vitenskapelig sammendrag

There is a lack of surveys including objective measurements of physical and cognitive function following multiple cohorts over the adult life span. We propose to carry out a representative health examination survey (N=1200) of the 1929, 1939, 1949 and 1959 birth cohorts in the Norwegian county of Oppland (where 4% of the Norwegian population lives).

The survey will include face-to-face-interviews to gather objective measurements on physical performance (grip strength, gait speed, standing balance, and chair rise time) and cognitive function as well as anthropometric measures (height, weight and waist circumference), blood pressure and DNA samples. A questionnaire will include measurements on mental health and responses on social and work-related information, self-assessed and retrospective health, expectations on longevity, quality of life, volunteering, type and quality of work, and consumption. Administrative registers will be linked to the data by the unique personal identification number and provide information on disability status, socioeconomic status (education, work, income, wealth), household and marital status, support to/from children and parents, and pension status.

Tests and questions will be made compatible with those of HRS-type surveys, and the survey will be made comparable with other surveys of those aged 50 and more, including HRS, SHARE and SAGE. This allows objective measures of economic and social activities as well as physical/mental function; avoiding recall bias from retrospective questions. We will match the collected information with future information on mortality and cause-of-death.

Moreover, the longitudinal dimension will follow from using objective tests from several points over the life-course – including anthropometric measures and IQ-assessment from military test data (all Norwegian men aged 18-20 years from 1949 cohort onwards), extensive mid-life cardiovascular health examinations (30-49 year olds, both sexes, up to three waves, tested 1976-88) - and the proposed survey material – aimed to be collected in 2017 (55-85 year olds, both sexes). We will use tests (including health analysis and cognitive test batteries) to ensure comparability over time, across cohorts and relatively to other countries and regions. For the cognition tests, the 37-47 year span will minimize any "retest bias" in cognition (short intervals tend to bias test performance).

A key strength of this survey is the combination of data on health and functioning with economic and social information (e.g., retirement, intergenerational support). NORSE-Oppland will also include the institutionalized population and thereby reduce sample bias (which is not done in for instance SHARE). This survey aims to fill the gap of surveys that include objective tests of multiple birth cohorts that can be followed over most of an economically active life cycle.

Summarizing, NORSE-Oppland will increase our ability to answer questions such as: What matters for healthy ageing – your childhood factors, your adult lifestyle and events, or both? How can lifecycle variation in skills and health affect mortality? How does the risk of disability and functional abilities change over the life cycle? What happens to cognitive abilities as individuals grow older - how protective is a high cognitive and health level at younger ages? Does dementia-free life expectancy change across cohorts? What determines at what age individuals retire and how they plan for their retirement? How much longer would later born cohorts potentially be able to work based on trends in health and cognitive function across cohorts? It will also allow us to learn from experiences how to conduct a similar survey on a national level. The data will be made publicly available to other researchers, free of costs for research purposes, given security arrangements to ensure data misuse and protect anonymity.
