In order to make a necessary life-style change, it is of the utmost im
portance that a sound motivation is created and the best help a person
can get in the process of change is social support. The aim of this s
tudy was to locate people having physical symptoms of ill-being and to
evaluate the work of a primary prevention programme, especially with
regard to health benefits. The sample for the study was made up of 134
consecutive patients who went to see a health care professional becau
se they had subjective complaints. The patients were offered a keep-fi
t exercise programme, i.e. a layman intervention of an educative-suppo
rtive nature, which consisted of ten assignments in a fitness club. Th
e assignments comprised both physical exercise and psychosocial instru
ctions. Two self-rated questionnaires were to be filled in; one at the
beginning of the intervention and the other 1 year after its completi
on. Demographic data focused the attention on a female, manual, middle
-aged worker, having symptoms bearing on the musculoskeletal system. T
he intervention definitely affected the life-style, thus favourably ch
anging physical, psychosocial, and behavioural variables (e.g. increas
ed physical well-being, t-test: P < 0.001; decreased stress, t-test: P
< 0.001; increased physical events, t-test: P < 0.01). In plain langu
age, the use of the said intervention can result in the patients takin
g less time on sick-relief. Therefore, if many more people could be en
couraged to take part in intervention programmes, the national medical
cost would most likely be reduced. Reflecting upon the result of the
study, there is a reason to wish that future intervention programmes b
e more concerned about the patients' working areas and their leisure t
ime.
