Persistent effect at 30-month post intervention of a community-based randomized trial of KM2H2 in reducing stroke and heart attack among senior hypertensive patients

Table 2 Differences in regular physical activity between the KM2H² and the standard care groups at baseline, 6-month and 30-month post intervention

Variables/Times	KM2H²		Control		p value
Regular physical activity	Crude	Adjusted	Crude	Adjusted
Regular physical activity	% (n/N)	% [95% CI]	% (n/N)	% [95% CI]
Baseline	56.28 (130/231)	54.26 [44.84,63.68]	48.58 (103/212)	45.68 [36.38,54.98]	0.08
6-month	79.23 (145/183)	75.57 [65.60, 85.54]	42.69 (73/171)	42.12 [32.22,52.03]	<0.01
30-month	65.27 (109/167)	64.98 [54.81,75.16]	43.62 (65/149)	40.97 [30.78,51.16]	<0.01
Duration of regular physical activity	Crude	Adjusted	Crude	Adjusted
Duration of regular physical activity	Mean (SD)	Mean [95% CI]	Mean (SD)	Mean [95% CI]
Baseline	2.93 (1.20)	2.71 [2.43,2.99]	2.84 (1.12)	2.74 [2.46,3.02]	0.87
6-month	3.48 (0.99)	3.34 [3.05,3.62]	2.97 (1.35)	2.84 [2.54,3.12]	<0.01
30-month	3.00 (1.85)	2.83 [2.54,3.12]	2.64 (1.23)	2.46 [2.17,2.76]	0.04

Note: SD standard error, CI confidence interval. The adjusted proportion and mean were estimated and compared by using general linear mixed effects model (regular physical activity) and mixed effects model (duration of regular physical activity) controlling for effect of cluster randomization, repeated measures, baseline difference, and covariates
