"Elderly persons in the risk zone" is a health-promoting and preventive intervention study. The intention was that the study group should comprise a representative sample of pre-frail 80-year old persons still living at home in two municipalities of Gothenburg: The participants should live in their ordinary housing and not be dependent on the municipal home help service or care. Further, they should be independent of help from another person in activities of daily living and be cognitively intact, having a score of 25 or higher as assessed with the Mini Mental State Examination (MMSE).

The participants were randomised to three study groups: two intervention groups and one control group.
- Intervention A; Senior meetings and one follow-up home visit
- Intervention B; Preventive home visit
- Control group

459 persons were included in the study, 171 in intervention A, 174 in intervention B and 114 in the control group. All participants received a first visit that comprised an interview, assessment and observation. The first visit, i.e.the baseline interview, was performed in the participant's

Sampling procedure

Probability: Simple random
Eligible persons for the study were drawn from official registers of all persons over 80 years of age in the two municipalities. Equal numbers from the two municipalities were listed in random order. The persons were included in the sample consecutively using the simple random sampling chart until the intended sample size was reached. Invitation letters were then sent to all persons in the sample asking them to participate in the study. The letter described the study, how it would be conducted and what would be expected of those consenting to participate. The letter stressed the fact that participation was voluntary. The letter was followed up by a telephone call about 1-2 weeks later. 365 persons out
of 2031 persons were either non-eligible or not traceable. The remaining persons was then informed verbally about the study and given the opportunity to ask questions if anything was unclear. They were also asked personally if they would like to participate, while again stressing that this was voluntary. After a baseline interview, those who fulfilled the study criteria were randomised to one of the three study arms by the use of sealed opaque envelopes. If eligible persons lived together, they were always allocated to the same intervention group.
