Study: Frequent drinking a heart risk for women

Young to middle-aged women who drink more than one alcoholic beverage a day, on average, were more likely to develop coronary heart disease than people who drink less, according to new research by Kaiser Permanente Northern California.

Women in the study who reported drinking eight or more alcoholic beverages per week were 33% to 51% more likely to develop coronary heart disease. And women who binge drink — three alcoholic beverages per day — were 68% more likely to develop coronary heart disease than those who drink in moderation, the research showed.

“There has been an increasing prevalence of alcohol use among young and middle-aged women as women may feel they’re protected against heart disease until they’re older, but this study shows that even in that age group, women who drink more than the recommended amount of one drink per day or tend to binge drink, are at risk for coronary heart disease,” Jamal Rana, a cardiologist with the Permanente Medical Group and the study’s lead author, wrote in an email.

The study will be presented at the American College of Cardiology’s Annual Scientific Session in early April. It was funded by the National Institutes of Health and the National Institute on Alcohol Abuse and Alcoholism.

The study used data from 432,265 adults, ages 18 to 65, who received care in the Kaiser Permanente Northern California integrated health organization. The group was composed of about 243,000 men and 189,000 women who filled out routine assessments between 2014 and 2015 in which they reported their alcohol intake.

Researchers then looked at the coronary heart disease diagnoses among participants over the four years that followed.
