An outreach program in which barbers served as health educators – monitoring their black male clients’ hypertension and referring them for medical treatment when necessary – improved the rate of blood pressure control by about 9% over 10 months, according to a report published online Oct. 25 in the Archives of Internal Medicine

Barbers were used as health educators in an outreach program to improve the rate of blood pressure control in black men. The researchers described the barbershop as a cultural institution and an open forum of discussion for topics including health.
The intervention, which was tested in 17 black-owned barbershops in a single Texas county, motivated about half the hypertensive patrons at participating barbershops to see a physician, and reduced their systolic blood pressure by a mean of 2.5 mm Hg, said Dr. Ronald G. Victor of the University of Texas Southwest Medical Center, Dallas, and his associates.
“If the intervention could be implemented in the approximately 18,000 black-owned barbershops in the United States to reduce blood pressure by 2.5 mm Hg in the approximately 50% of hypertensive U.S. black men who patronize these barbershops (2.2 million persons), we project that about 800 fewer myocardial infarctions, 550 fewer strokes, and 900 fewer deaths would occur in the first year alone, saving about $98 million in [coronary heart disease] care and $13 million in stroke care (but offset by $6 million in additional non-CHD costs contributed by persons who would otherwise have died),” the investigators noted.
Black-owned barbershops “are rapidly gaining traction as potential community partners for health promotion programs targeting hypertension as well as diabetes, prostate cancer, and other diseases that disproportionately affect black men,” the researchers said.
Such barbershops “are a cultural institution that draws a large and loyal male clientele and provides an open forum for discussion of numerous topics, including health, with influential peers.”
However, despite the growing trend of using barbershops in this manner, the effectiveness of barber-based interventions has not been assessed in a randomized trial.
Dr. Victor and his colleagues did so by offering free blood pressure screening to patrons of 17 barbershops representing four geographic sectors with sizeable black populations in the Barber-Assisted Reduction in Blood Pressure in Ethnic Residents (BARBER-1). Nine barbershops with 695 patrons who were found to have hypertension then were randomly allocated to the intervention, and eight barbershops with 602 patrons who had hypertension were randomly allocated to a comparison group.
Most of the barbershop clients were middle-income.
The comparison group was not strictly a control group; patrons there underwent two BP screenings at baseline and received standard written explanations and recommendations for physician follow-up, because failing to advise them would have been unethical. The comparison barbershops also made available American Heart Association pamphlets entitled “High Blood Pressure in African Americans.”
For the intervention, barbers continually offered all male clients blood pressure checks along with their haircuts. They displayed large posters depicting authentic stories of other male hypertensive patrons of the same shop modeling treatment-seeking behavior, using the model’s own words to tell the story. Barbers and other male patrons also discussed the issue conversationally.
The barbers were trained, equipped, and paid to conduct BP testing and interpret the results, with the main focus on encouraging clients who had positive results to consult a physician. They referred clients who had no physician to a nursing staff that then referred them to local physicians or safety-net clinics. Barbers also gave patrons found to be hypertensive a wallet-sized card for the physician to sign, documenting an office visit concerning hypertension.
The barbers were paid $3 for every recorded blood pressure they took, $10 for every referral they made to the nursing staff, and $50 for every BP card that clients returned to them with physicians’ signatures. Patrons received free haircuts (a $12 value) for every BP card they returned with a physician’s signature.
Overall, nearly half of the patrons who were screened had high blood pressure; 78% of them were already aware that they were hypertensive, and 69% said they were taking treatment for HT, yet only 38% had their blood pressure under control.
Barbers were able to measure blood pressure in three of every four patrons who had hypertension, and each hypertensive client averaged eight blood pressure checks during the 10-month study. “The barbers motivated 50% of their patrons with elevated BP readings to visit a physician,” the researchers said.
The rate of blood pressure control – the number of men who achieved blood pressure control during BARBER-1 – improved by about 10% in the comparison group, but improved by an additional and significant 8% in the intervention group. That represents a nearly 20% improvement over the baseline rate of blood pressure control.
