The first part presents an overall summary of the scientific evidence related to the three studies that compose this thesis. The second part includes three scientific articles published and one being under-review, where the PhD candidate is the first author. The third part summarizes the main results of the three studies. The fourth part is the general discussion for the three scientific articles, with the strength and limitations of the present studies and recommendations for future research. The present thesis consisted in three studies I, II and III. The study I gives an insight on the prevalence of PA among Catalan population and identify the most physically active and the most sedentary population groups. The study II explores PA level and other lifestyle-related behaviours within Catalan physicians. The study III assesses the recent implantation of Physical Activity Referral Scheme (PARS) in primary health care centres in Catalonia. The first two studies describe the prevalence of PA among representative samples of Catalan population and Catalan physicians. The study I focused on describing the prevalence of both Health-Enhancing Physical Activity (HEPA) and Leisure-time Physical Activity (LTPA) in the Catalan population. It also identifies associated factors to the most active and the most sedentary population’s groups. The results from the Catalan population survey identify those population groups most needed of PA interventions. Considering PA counselling a powerful strategy to promote PA to general population in primary care (Petrella & Lattanzio, 2002), it was necessary to assess the effectiveness of a PA referral scheme in the Catalan context. According to previous literature, PA counselling is influenced by physicians own habits. PA counselling is more effective when physicians presented positive health behaviours and regularly exercise (Abramson, Stein, Schaufele, Frates, & Rogan, 2000; Lobelo, Duperly, & Frank, 2009; Frank, Segura, Shen, & Oberg, 2010). 1 Given the importance of physicians own habits on PA counselling and the lack of previous data on PA level of physicians in Catalonia, it was important to explore the PA level and other health-related behaviours of Catalan physicians in the study II. This study gives an insight of the lifestyle-related behaviours of Catalan physicians, particularly PA habits and identify those most physically active and the most sedentary. Exploring the profile of the most physically active physicians is relevant to managers of health care systems to identify those who are more likely to be better PA promoters. The study III focuses on assessing the recent implantation of a PA referral scheme in Catalan primary care centres by the Plan of Physical Activity, Sport and Health (PAFES). There was a need to test PARS in the Catalan primary are centres to assess its effectiveness and justify its implementation. These results are related to both studies I and II. The study I identifies target groups to increase PA and study II describe the health-related behaviours of physicians that are in part, related to PA counselling.
