The DASH diet combined with walking reduced 24-hour systolic ambulatory blood pressure by 12.5 mm Hg compared to 1.5 mm Hg in the control group in patients with type 2 diabetes and hypertension.

Does a DASH diet combined with increased walking reduce blood pressure in patients with type 2 diabetes and uncontrolled hypertension?
A 4-week lifestyle intervention combining the DASH diet and increased walking significantly reduced ambulatory blood pressure in patients with type 2 diabetes and uncontrolled hypertension.
Absolute Event Rate: -12.5% vs -1.5%
p-value: p=<0.001
Data on the potential beneficial effects of combining diet and exercise on blood pressure (BP) are still scarce. A 4-week randomized controlled clinical trial was undertaken in 40 hypertensive patients with type 2 diabetes with uncontrolled blood pressure (BP) in office and daytime ambulatory BP monitoring (ABPM). Patients were assigned to follow a Dietary Approaches to Stop Hypertension (DASH) diet associated with advice to increase walking using a pedometer (intervention group) or a diet based on the American Diabetes Association recommendations (control group). The lifestyle intervention caused a greater ABPM (mm Hg) reduction in systolic 24-hour, diastolic 24-hour, nighttime systolic, daytime systolic, and daytime diastolic measurements than observed in the control group. In the intervention group there was a decrease in urinary sodium and an increase in urinary potassium, plasma aldosterone, and the number of steps per day (P<.05). The DASH diet and increased walking were associated with clinically significant reductions in ABPM values in hypertensive patients with type 2 diabetes.
Paula et al. (2015) conducted an RCT in Type 2 diabetes and uncontrolled hypertension (n=40). DASH diet and walking vs. ADA diet and usual physical activity was evaluated on Change in 24-hour systolic ambulatory blood pressure (mm Hg) (p=<0.001). The DASH diet combined with walking reduced 24-hour systolic ambulatory blood pressure by 12.5 mm Hg compared to 1.5 mm Hg in the control group in patients with type 2 diabetes and hypertension.
