Physical Activity Counseling for Adults with Hypertension: A Randomized Controlled Pilot Trial

The effect of physical activity counseling (PAC) in hypertensive adults is unclear. This study investigated the effect of PAC on blood pressure (BP), physical activity level, sitting time, metabolic profile, and body composition in hypertensive adults. Twenty-two hypertensive adults (48.8 +/- 7.3 years) participated in this pilot trial. The 12-week PAC was based on the 5 A's model considering the FITT principle (Frequency, Intensity, Time, and Type) of physical activity. The control group received instructions about FITT in one face-to-face meeting at baseline. Pedometer-measured physical activity, sitting time, resting and ambulatory BP, metabolic profile (cholesterol, triglycerides, fasting glucose), and body composition (fat mass, abdominal fat, fat free mass) were assessed. The PAC group showed higher steps per day (5839 +/- 992 vs. 5028 +/- 902;p= 0.044) and a trend for lower sitting time (5.6 +/- 1.3 vs. 8.0 +/- 4.0 h/day; p= 0.059) than the control group. No changes were observed in BP, metabolic profile, and body composition (p >0.05). In conclusion, 12 weeks of a PAC program based on the 5 A's model resulted in a modest increase of similar to 800 steps per day and a trend to decrease similar to 2 h/day in sitting time, but there were no associated reduction in BP and improvements in metabolic and body composition.
