Just one drink a day can raise blood pressure, study says
As little as one alcoholic drink a day increased systolic blood pressure — the top number in a blood pressure reading — even in men and women with no existing hypertension, a new study found.
“We found no beneficial effects in adults who drank a low level of alcohol compared to those who did not drink alcohol,” said senior study author Dr. Marco Vinceti, a professor of epidemiology and public health at the University of Modena and Reggio Emilia in Italy, in a statement.
The negative impact of alcohol on systolic blood pressure continued to rise over the years, the study found, even in men and women who drank little each day. Small amounts of alcohol also raised the lower, or diastolic blood pressure reading, but only in men, according to the study, which was published Monday in the journal Hypertension.
“Both systolic and diastolic readings contribute to (cardiovascular) risk and go hand in hand, but of the two, systolic blood pressure is definitely the most important risk factor in adults,” said study coauthor Dr. Paul Whelton, chair in global public health at Tulane University’s School of Public Health and Tropical Medicine in New Orleans and president of the World Hypertension League.
Blood pressure and cardiovascular health
Blood pressure is measured in units of millimeters of mercury (abbreviated as mmHg), and written as two numbers, one above the other. The top or systolic reading, which represents the force of blood against artery walls when the heart contracts, is a “major risk factor for cardiovascular disease for people over 50,” according to the American Heart Association. The lower diastolic reading measures pressure in the arteries as the heart muscle rests between beats.
