The Population perspective


The longitudinal collection of data from the population perspective concerns the follow-up of health, sickness, functional ability, social contacts and need for care in a representative panel (that consists of a selection of persons from the elderly population) by continuous medical examinations, interviews, questionnaires etc.
This information will be supplemented with different types of registered data. The four areas use a common project design.

In the year 2007 a whole new cohort of people at 60 and 81 years of age. These are to be examined 2007, 2008 and some in 2009. At the same time the old cohort with all the different agegroups are examined.

In the years 2004-2006 a reexamine of all people above the age of 81 was examined.

Åren 2004-2006 gjordes en återundersökning av de som då var 81 år eller äldre.

During 2001-2003 a so-called baseline investigation has been done, regarding a selection of the elderly living in each of these areas – those aged 60, 66, 72, 78, 81, 84, 87, 90, 93, 96 and 99 years of age. These persons will then be followed up regularly – the younger group every sixth year and the older every third year. The selection comprises a total of roughly
11,000 people. An additional selection of younger and older people has been financed using a research grant. Every sixth year a new group of 60 year olds is added to the population study. In this way it will be possible to both follow ageing in individual cases within separate age groups and social conditions and compare groups – for example with regard to health improvements. Through the enormous amount of information that is collected on each individual, ageing with the appearance/development of disabilities and care-needs can be studied from many points of view and against a background of a variety of conceivable influencing factors.
