For the combined total or within community, analysis based on paired t test (H0: μpair-diff = 0). Data are shown as mean ± standard deviation. Refer to Table 2 for baseline means and standard deviation. BP blood pressure, 6MWT 6-min walk test, Physical Activity Fq physical activity frequency score. Across four communities, one-way ANOVA used to compare the changes from baseline. Differences are indicated by an asterisk next to the name of the measure, adjusted for differences at baseline. Change scores based on post-intervention values minus baseline values. Physical Activity Frequency Score: frequency of moderate-vigorous physical activity, range 1 = ≥4 times/week (more active) to 4 = rarely or never (less active). Thus, lower scores are more active and a negative change means more physical activity. Fat in Diet Score of 2.5 or greater indicates greater than 30 % of calories from fat.
