Using blood pressure self-monitoring is an effective way to empower patients with hypertension to stick with an exercise program, according to a first-of-its-kind study conducted by a multidisciplinary team of UConn researchers in collaboration with Hartford Hospital.<\/p>\n

The findings, recently published in the Journal of Hypertension<\/em><\/a>, confirm a long-held but previously untested theory by the study\u2019s principal investigator, Linda Pescatello, a distinguished professor in UConn\u2019s Department of Kinesiology, and Dr. Paul Thompson, chief of cardiology at Hartford Hospital, that blood pressure self-monitoring can and should be used as a behavioral strategy to help keep patients with hypertension engaged in an aerobic exercise training program, a proven means of addressing the chronic condition known to be a leading risk factor for cardiovascular disease.<\/p>\n

\u201cWe know that hypertension is the most common and costly, but modifiable, chronic condition in the U.S. and world,\u201d says Amanda Zaleski, a postdoctoral fellow in UConn\u2019s Department of Kinesiology who works as an exercise physiologist in Hartford Hospital\u2019s Department of Preventive Cardiology. Zaleski is the lead author of the study, which was her doctoral dissertation.<\/p>\n

\u201cWe know that regular aerobic exercise lowers blood pressure on average to the order of five to seven points,\u201d she says, \u201cand these reductions are even greater for those with higher baseline blood pressure.\u201d<\/p>\n

The difficulty, Zaleski adds, is that hypertension causes no outward symptoms, and patients often become frustrated when they don\u2019t know or understand what their blood pressure values are and don\u2019t see results from lifestyle modifications. These frustrations can make starting and, perhaps more importantly, sticking with an exercise training program more difficult for many patients.<\/p>\n

The research team \u2013 which included experts in kinesiology, psychology, cardiology, and statistics, among other disciplines \u2013 set out to test their long-held notion that encouraging patients to monitor their own blood pressure, especially before and after exercising, would not only show the patients that exercise had an immediate, positive effect on their blood pressure, but also would help them better adhere to an exercise training program.<\/p>\n

Exercise, Zaleski says, lowers blood pressure immediately, an effect first established by Pescatello in a 1991 study<\/a> which showed that, after one single bout of exercise, blood pressure drops about five to seven points and that this reduction persists for up to 22 hours after the exercise.<\/p>\n

She says these blood pressure reductions serve as an objective biomarker that people can measure and see with their own eyes. “This is really powerful for someone with hypertension because it enables them to demonstrate to themselves that their blood pressure is lower on days they exercise than on days that they do not. There are very few chronic conditions that respond this way to exercise. Imagine if an individual with overweight\/obesity lost five to seven pounds after a single bout of exercise?\u201d<\/p>\n

The researchers recruited 24 participants with hypertension and engaged them in a 12-week supervised aerobic exercise training program. Half of the study participants self-monitored their blood pressure twice a day as well as before and after exercising, and the other half did not self-monitor their blood pressure at all. Most of the participants exercised on a treadmill for 40-minute supervised sessions three times a week at moderate intensity, and they were encouraged to exercise on their own at home in addition to the training sessions.<\/p>\n

While both groups saw their blood pressure values lowered by the end of the 12 weeks, the group engaged in self-monitoring lowered their blood pressure by about double the magnitude \u2013 about 10 points \u2013 compared to the group that was not self-monitoring, which saw an average five-point reduction.<\/p>\n

But the study didn\u2019t end there.<\/p>\n

Four weeks after the supervised training period ended, Zaleski and other kinesiology graduate and undergraduate students conducted telephone exit interviews with the study participants and asked whether they were still engaging in physical activity and, for those in the self-monitoring group, if they were still checking their own blood pressure.<\/p>\n

In total, about 75 percent of the study participants were still maintaining some level of exercise, but those who were in the blood pressure self-monitoring group were engaging at an average of 70 percent of their previous exercise training volume \u2013 compared to the other group, who were only engaging in about 30 percent as much exercise as when they were supervised.<\/p>\n

Within the self-monitoring group, 60 percent of the participants were still measuring their own blood pressure and those participants still self-monitoring were engaged in even greater physical activity \u2013 exercising for 45 minutes at least three and a half days per week. This compared to those who were not measuring their blood pressure, who were exercising for about 19 minutes one day a week.<\/p>\n

\u201cThat was really promising to us,\u201d Zaleski says, \u201cdemonstrating that if they\u2019re out on their own in the free living world, with all of the other confounders that can come into play \u2013 like stress, family, vacations \u2013 that even without our team holding them accountable, the favorable effects of blood pressure self-monitoring still held true.\u201d<\/p>\n

Study co-author Beth Taylor notes that blood pressure is one of the only ways to see non-invasively the effects of lifestyle modification.<\/p>\n

Taylor, director of exercise physiology research in cardiology at Hartford Hospital and an assistant professor of kinesiology at UConn, says most clinical guidelines right now call for patients to monitor their blood pressure at home; gold-standard, accurate, and easy-to-use blood pressure monitors are available for patient use at home for less than $100. But using blood pressure monitoring before and after exercise, she says, when most patients would be able to see for themselves a notable drop in their blood pressure, would represent a new behavioral health strategy for providers to employ to help increase adherence to an exercise training program.<\/p>\n

Both Taylor and Zaleski says that additional studies, with larger sample sizes, are needed to try to replicate the findings. Additionally, for reasons currently unknown, 10 to 20 percent of people do not demonstrate the same drop in blood pressure immediately following exercise, which could limit the effectiveness of self-monitoring as a behavioral modification strategy.<\/p>\n

But, says Taylor, exercise is important for a host of different reasons \u2013 including body weight management, bone density, and overall health \u2013 and blood pressure self-monitoring could have lifestyle modification implications well beyond treating hypertension.<\/p>\n

\u201cThis is a great study that shows how we might increase exercise adherence for patients with hypertension,\u201d she says. \u201cCould this be a \u2018gateway drug\u2019 to getting people to exercise for an abundant variety of reasons?\u201d<\/p>\n

In addition to Pescatello, Thompson, Zaleski, and Taylor, co-authors on the study include Crystal L. Park, a UConn professor of psychological sciences; Lucas Santos, a visiting scholar and graduate student at the Federal University of Rio Grande do Sul in Brazil; Gregory Panza and Melody Kramarz, UConn graduate students in kinesiology; Kyle McCormick, an undergraduate student majoring in kinesiology; Dr. Antonio B. Fernandez, medical director of the Cardiac Intensive Care Unit at Hartford Hospital; Ming-Hui Chen, a UConn professor of statistics; Bryan Blissmer, a professor and director of the Institute for Integrated Health and Innovation at the University of Rhode Island; and Kim M. Gans, a UConn professor of human development and family sciences.<\/p>\n

The study was funded by UConn\u2019s Office of the Vice President for Research and was supported by the Department of Preventive Cardiology at Hartford Hospital.<\/em><\/p>\n
