Higher the alcohol intake, more the postmenopausal muscle wasting

Feeling as though you can't do as much physically as you've gotten older? According to a recent study, you can put the blame on your boozing habit.

Both aging and menopause are known to affect sarcopenia, which is a loss of muscle mass and strength, which in turn affects balance, gait, and overall ability to perform tasks of daily living.

The research is one of the first to link alcohol consumption with a higher prevalence of sarcopenia in postmenopausal women.

The Korean-based study included 2,373 postmenopausal women (mean age, 62.4 y), 8.2% of whom were identified as having sarcopenia. Participants were categorized into three groups according to alcohol-drinking patterns, as assessed by the Alcohol Use Disorders Identification Test questionnaire.

Study results showed that the prevalence of sarcopenia was found to be nearly four times greater for the high-risk, alcohol-drinking group than the low-risk group. High-risk drinking was determined by the self-reporting of quantity and frequency of alcohol consumption, combined with a perceived lack of control over drinking, as well as blackouts and other injuries related to drinking.

Women in the high-risk, alcohol-drinking group were more likely to be current smokers and have worse blood pressure and total cholesterol. They were also significantly younger.

"Preclinical studies suggest a possible benefit of estrogen therapy when combined with exercise to increase strength and performance and to prevent the loss of muscle mass, but the role of estrogen in muscle mass is not yet clear for postmenopausal women," said JoAnn Pinkerton.

"With this study suggesting that more muscle loss leads to sarcopenia and other studies suggesting that even one drink of alcohol may increase the risk of breast cancer, postmenopausal women should limit their alcohol intake," noted Pinkerton.

The study is published online in Menopause, the journal of The North American Menopause Society (NAMS).
