Background: Declining physical activity is associated with a rising burden of global disease. There
is little evidence about effective ways to increase adherence to physical activity. Therefore,
interventions are needed that produce sustained increases in adherence to physical activity and are
cost-effective. The purpose is to assess the effectiveness of a primary care physical activity
intervention in increasing adherence to physical activity in the general population seen in primary
care.
Method and design: Randomized controlled trial with systematic random sampling. A total of
424 subjects of both sexes will participate; all will be over the age of 18 with a low level of physical
activity (according to the International Physical Activity Questionnaire, IPAQ), self-employed and from
9 Primary Healthcare Centres (PHC). They will volunteer to participate in a physical activity
programme during 3 months (24 sessions; 2 sessions a week, 60 minutes per session).
Participants from each PHC will be randomly allocated to an intervention (IG) and control group
(CG). The following parameters will be assessed pre and post intervention in both groups: (1)
health-related quality of life (SF-12), (2) physical activity stage of change (Prochaska's stages of
change), (3) level of physical activity (IPAQ-short version), (4) change in perception of health
(vignettes from the Cooperative World Organization of National Colleges, Academies, and Academic
Associations of Family Physicians, COOP/WONCA), (5) level of social support for the physical activity
practice (Social Support for Physical Activity Scale, SSPAS), and (6) control based on analysis (HDL,
LDL and glycated haemoglobin).Participants' frequency of visits to the PHC will be registered over the six months before and after
the programme. There will be a follow up in a face to face interview three, six and twelve months
after the programme, with the reduced version of IPAQ, SF-12, SSPAS, and Prochaska's stages.
Discussion: The pilot study showed the effectiveness of an enhanced low-cost, evidence-based
intervention in increased physical activity and improved social support. If successful in
demonstrating long-term improvements, this randomised controlled trial will be the first
sustainable physical activity intervention based in primary care in our country to demonstrate longterm
adherence to physical activity.
