A neighborhood barbershop might seem to some Americans like a thing of the past. Today men often get their hair cut at the same salons as women. But the traditional barbershop still holds a special place in black culture.(16)A barbershop is a place of trust where men can talk about things they might not want women to hear. This is why black-owned barbershops increasingly offer more than just a haircut. Men also receive health education and testing that could save their lives. A new study has examined the barbershop health-care model. The study involved about 1 300 customers at 17 black barbershops. Researchers had the barbers at eight of the shops continue to just give haircuts. The other barbers learned how to measure blood pressure and offered it with every haircut. If a customer had high blood pressure, the barber would intervene. The customer would be urged to see a doctor. (17)Customers who went to a doctor would get their next haircut free of charge. The study lasted ten months. All of the men had their blood pressure taken at the start. (18)The study found that blood pressure rates decreased at the shops where the barbers intervened and also at those where they did not. But the difference was in the amount. Twenty percent of the men who were urged to see a doctor got their blood pressure down to a healthy level. So did only 11% of the men who just got haircuts. Dr. Ronald Victor, the study leader, says(19)barbers historically were members of the medical profession. So he thinks it makes a lot of sense for today’s barbers to act as "health care extenders" by sharpening their skills.
