Stages of change for exercise, sociodemographic variables, and beliefs
about the health benefits of exercise were obtained for a representat
ive sample of Australian adults (N = 4404). Logistic regression analys
is was used to examine the relationship between exercise stage of chan
ge and sociodemographic variables and beliefs about the benefits of ex
ercise. Thirteen percent of respondents stated that they did not exerc
ise and did not intend to start; 10% stated that they did not exercise
but were thinking of starting; 16% stated that they exercise occasion
ally and were not thinking of doing more; 23% stated that they exercis
ed occasionally and were thinking of doing more; and 38% stated that t
hey exercised regularly and intended to continue. Intention to do more
exercise generally decreased with increasing age, but increased with
level of education. An increased frequency of exercise and an intentio
n to do more exercise was associated with the belief that exercise wou
ld help to prevent heart disease and with a higher level of education.
The results provide a useful profile of the exercise habits (and inte
ntion to change those habits) of population subgroups. Public communic
ation campaigns on the benefits of physical activity should focus part
icularly on those who do not intend to exercise, older adults, and the
less well educated.
