Adjusted prevalence of physical activity over the 3-year intervention period. Adjusted prevalence is shown for those met recommended level of overall physical activity (a), walked 150 min/week or over (b), engaged in flexibility activity daily (c), and engaged in muscle-strengthening activity for 2 days/week or over (d). In each community in the intervention subgroups, aerobic activity (Group A), flexibility and muscle-strengthening activities (Group FM), or all aerobic, flexibility, and muscle-strengthening activities (Group AFM) were promoted. The prevalence is adjusted for sex, age, body mass index, self-rated health, years of education, employment status, engagement in farming, chronic low back and knee pain, chronic disease history, and community (cluster) where the respondents lived; 95 % confidence intervals of specific physical activities (b, c, d) are presented only for groups with the lowest or highest prevalence over the period. Range of confidence-bar lengths for specific physical activities is 4.2-6.6
