We introduce a conceptual framework with social relations as the main conce
pt and the structure and the function of social relations as subconcepts. T
he structure of social relations covers aspects of formal relations and soc
ial network. The function of social relations covers social support, social
anchorage and relational strain. We use this conceptual framework to descr
ibe social relations in the Danish population, with questionnaire data from
the Danish Longitudinal Health Behaviour Study including a random sample o
f each of the age groups 25-, 50-, 60- and 70-year olds,.N = 2,011. The pos
tal questionnaires were answered by a random sample in each of the age grou
ps. The results show marked age and gender differences in both the structur
e and the function of social relations. The social network, measured as wee
kly contacts, weakens with age and so does instrumental support. Emotional
support is unrelated to this decline in contact frequency and appears to be
at the same level for younger and older individuals. Relational strain, me
asured as conflicts, declines with age for all kinds of social relations. T
he weakening of the social network with age does not seem to affect the lev
el of emotional support and in turn seems to be partly compensated for by a
simultaneous decline in relational strain. (C) 1999 Elsevier Science Ltd.
