The Link Between Alcohol and Body Weight
Results
from studies on alcohol intake and body weight are inconsistent.
To help clarify the association between alcohol use and
waist-to-hip ratio (WHR) and body mass index (BMI), researchers
in France analyzed data from 2323 adults, aged 35-60,
who had participated in a study of antioxidant supplementation.
Analyses were adjusted for age, smoking, physical activity,
education, and calorie intake.
- Overall,
the relationship between total alcohol consumption and
WHR was J-shaped*; those consuming 0-12 g (equal to
1 standard drink or less) per day had a lower ratio
than did those who drank more or abstained. The J-shaped
relationship was also seen for total alcohol consumption
and BMI, but in men only. - The
J-shaped curves were due primarily to wine intake. Those
who consumed 0-100 g (up to 8 glasses) of wine per day
had a lower WHI than did those who drank more wine or
no wine. The J-shaped relationship was also seen for
wine intake and BMI, but in men only. -
Spirits consumption increased
WHR and BMI in a linear fashion for both men and women. -
Beer consumption did not
significantly affect WHR or BMI.
Comments:
This
study showed a J-shaped association between measures of
obesity and alcohol, primarily wine, intake. Whether the
favorable effects of wine were due to polyphenols or to
inadequate control of confounding (e.g., lifestyle of
wine drinkers versus beer drinkers) is unclear. Therefore,
recommending drinking to prevent obesity would be premature.
However, gaining a better understanding of how alcohol
consumption relates to obesity—an increasingly prevalent
health problem—is very important.

*Researchers determined that the curve was J-shaped by conclusions drawn from regression equations.
