Background. There is increasing research supporting the argument for a
beneficial link between physical activity and health maintenance and,
in the past five years, this has led to a growth in physical activity
promotion schemes involving primary health care. Aim. To document and
critically examine the extent and nature of physical activity promoti
on in general practice in England. Method. A postal survey to all fami
ly health services authorities and primary care facilitators was condu
cted to identify existing and planned activity promotion schemes invol
ving primary health care. Telephone interviews with leaders from 50 se
lected schemes and further detailed case studies of 11 schemes provide
d descriptive information of the nature of physical activity promotion
. Results. The initial phase revealed 157 existing schemes and a furth
er 35 planned schemes. Two basic models of physical activity promotion
were identified that were distinguishable by the primary location of
the management of the patient. Practice-managed interventions (32%) in
volve on-site counselling to change the behaviour of patients. Leisure
centre-managed projects (68%), sometimes termed 'exercise by prescrip
tion' or 'general practioner referral for exercise' schemes, involve t
he identification of suitable patients and their referral to 10- to 12
-week-long leisure centre based exercise induction courses. The projec
ts in the planning stage were all of the latter type, indicating this
as the favoured model. Although such schemes were generally successful
in attracting patients, in all cases they involved less than 1% of th
e patient base from which they were drawn. Conclusion. There is eviden
ce of successful recruitment, increased short-term physical activity a
nd fitness, and improvements in the well-being of patients. However, s
chemes are inadequately resourced for rigorous long-term evaluation; t
herefore, conclusions regarding the cost-effectiveness of the two mode
ls are not possible.
