Do participants in a physical activity program from a Care Sport Connector become healthier? An explorative study from the Netherlands

Care Sport Connectors (CSCs) have been appointed to create a connection between the primary care and physical activity (PA) sectors to stimulate residents who are inactive to become more physically active to gain health benefits. The objective of this explorative study was to find out whether CSCs achieve these goals by testing the hypothesis that more residents become physically active, and score higher for health-related fitness and health-related quality of life. We conducted a longitudinal study design whereby participants (n = 402) were measured at three time points: at the start of their PA program (T0); after 6 months (T1); and after 1 year (T2). Participants conducted a fitness test to measure their health-related physical fitness and filled in questionnaires to assess PA level (PA-, Fit-, Combi-, and sport norm), health-related quality of life, motivation for PA, and personal information. We used a multi-level analysis to test whether outcomes of participants differ over time. Participants who dropped out and maintainers were compared with a chi-square test and a one-way ANOVA. This study showed that one-third of the participants dropped out (n = 139). Participants who dropped out were, compared with maintainers, less physically active (P = 0.004) and were more often reached in bigger municipalities, by an integral approach. More participants meet the PA norm (P = 0.007) and sport norm (P
