Outline of Final Research Achievements

A cluster randomized trial with community as unit of randomization were conducted to evaluate a 5-year community wide campaign (CWC) to promote physical activity. Randomly-sampled 4414 residents (40-79 years) responded to the baseline survey (74 %) and were followed from 2009 to 2014. As the results, CWC did not significantly increase proportion of active adults (adjusted change difference = +4.5 % [95 % Confidence interval: 0.3, 9.3], P=0.066). However, in the analyses using secondary outcomes, adults doing flexibility activity significantly increased in intervention communities (P=0.049), and adults doing walking tended to increase in intervention communities (P=0.058). In conclusion, CWC did not achieve significant increase in active adults at population level. However, the results of borderline significance and analyses of secondary outcomes suggested its potential effectiveness.
