Weight Gain & Alcohol
Weight Gain Study Background
There is uncertainty as to whether regular alcohol consumption contributes
directly to weight gain and the risk of obesity.
Weight Gain Study Aim
Examine the relation between alcohol intake and body weight and the association
between changes in alcohol intake and in body weight over 5 years of follow-up.
Weight Gain Study Method
A prospective study of 7608 men aged 40-59 years drawn from general practices
in 24 British towns, excluding persons with known diabetes. Five years
after screening, 6832 men then aged 45-64 years and without diabetes completed
a postal questionnaire on changes in alcohol intake and body weight.
Weight Gain Study Results
Mean body mass index (BMI; in kg/m2) and the prevalence of men with a
high BMI (28) increased significantly from the light-moderate to the very
heavy alcohol intake group even after adjustment for potential confounders.
Similar patterns were seen for all types and combinations of alcohol.
After 5 years of follow-up, stable and new heavy drinkers showed the greatest
weight gain and had the highest prevalence rates of high BMI. Weight change
patterns in heavy drinkers at baseline who reduced their intake were not
significantly different from those in the stable none-occasional group
but showed more weight loss and less weight gain than in the stable or
new heavy drinkers.
