People who received regular lifestyle counselling online were able to lower their blood pressure as much as a medication would, researchers said. Their study involved 264 people with high blood pressure and an average age of 58. The subjects’ average blood pressure began at around 140/90 mmHg, meaning they had what is clinically known as stage 1 hypertension. Most were already taking at least one drug to cut their blood pressure.
The control group saw more generic information about heart-healthy living. By the end of the study period, the more engaging online content seemed to have had an effect, and patients in that group reduced their systolic blood pressure – the higher number in a blood-pressure reading – by 10 millimetres of mercury (mmHg). That was a statistically significant difference compared to the control group, which saw a 6 mmHg reduction.
“The electronic counselling intervention had an effect similar to that of adding an additional blood-pressure-lowering medication,” said lead study author Robert Nolan, associate professor at the University of Toronto. “We think this lifestyle counselling intervention can complement and optimise the effectiveness of medical therapy to reduce high blood pressure.”
The study was released at American College of Cardiology’s annual meeting in Washington.
