The report, published in the New England Journal of Medicine, found that black men who visited a barbershop with a pharmacist-led blood pressure program had significantly better blood pressure levels six months later.
Black men have the highest rates of high blood pressure compared to any other racial, ethnic or gender group. They are also much less likely to go to the doctor compared to black women. In this experiment and others, public health interventions have targeted barbershops in order to improve the health of the men who visit them.
The researchers enrolled 319 black men from 52 different barbershops in Los Angeles County. The men in the study—who were 35 to 79 years old—had systolic blood pressure measurements of 140 or more. Normal blood pressure levels are 120/80 or less, and high blood pressure levels are 140/90 or higher.
Each man was assigned either to a control group or to a program, where his barber would recommend that he meet with a trained pharmacist at the barbershop. That pharmacist would measure the men’s blood pressure, encourage lifestyle changes and prescribe blood pressure medication.

In the control group, the barbers talked to the men about blood pressure and healthy lifestyle changes and encouraged them to see a health provider. But the men did not meet with a pharmacist in the barbershop.
The researchers found nearly 64% of the men who met with pharmacists monthly at their barbershop achieved a blood pressure level of less than 130/80 six months later, compared to the nearly 12% of the men in the control group.
The researchers write in the study that they believe the intervention succeeded because the pharmacists made getting blood pressure treatment very convenient. Also, barbers are often trusted community members, and men in the study went to see them often: around every two weeks, which helped ensure regular follow-up.
