Bottom Line: 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 pilot study showed the effectiveness of an enhanced low-cost, evidence-based intervention in increased physical activity and improved social support.

ABSTRACT

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 long-term adherence to physical activity.

Figure 1: Flowchart of participant's recruitment and trial design.

Mentions: Recruitment will take place in 9 PHC in different regions of Catalonia during the first three months of 2009. Until August 2008, 63 PHC in Catalonia were informed and the trial has been presented to the 54 centres which showed interest in participating. Of these, the first nine centres which volunteered to participate will undergo the trial. Two health professionals, who were selected on a voluntary basis from each of the participating centres, were trained. During the recruitment period, the opportunity to participate in the study will be offered daily to all patients with a chronic pathology, who by systematic random sampling will be previously identified in the doctors' lists: a total of 50 subjects per centre will be recruited. The patients who meet the inclusion criteria and agree to participate will be contacted to inform them about how the project will be carried out. A record of demographic and health data, as well as attendance at the sessions, will be kept of those who agree to participate in the intervention. Figure 1 shows the flowchart of participants' recruitment and trial design.
