The association of lifetime alcohol use with measures of abdominal and general adiposity in a large-scale European cohort



The relation between lifetime use of alcohol and measures of abdominal and general adiposity is unknown.

Among 99381 men and 158796 women of the European Prospective Investigation into Cancer and Nutrition (EPIC) study, means of waist circumference (WC), waist-to-hip-ratio (WHR) and body mass index (BMI), and odds ratios (OR) for a larger WC than predicted for a given BMI (WClp=positive residuals of gender specific linear regression of BMI on WC) across categories of average lifetime use of alcohol (total, from wine and from beer) were calculated, all adjusted for socio-demographic, lifestyle and health factors.

WC, WHR and BMI in men using lifetime 6g/d alcohol were 95.1cm, 0.942 and 27.3kg/m2, and 96.2cm, 0.961 and 28.3kg/m2 when using >96g/d. WC and WHR in women was 83.2cm and 0.813 for 6g/d, and 84.6cm and 0.830 for >60g/d, whereas BMI deviated only slightly with the lowest BMI (26.7kg/m2) observed for >6–24g/d. Compared with 6g/d, OR for a WClp in both genders increased steadily across categories of alcohol use (up to 1.40 (95% confidence interval 1.32, 1.49) in men using >60g/d and 1.63 (1.54, 1.73) in women using >24g/d), though increase was higher for alcohol from beer than from wine (P for difference between beer and wine<0.001 (men) and=0.002 (women)).

Lifetime alcohol use is positively related to abdominal and general adiposity in men, possibly following the male weight gain pattern; in women, it is positively related only to abdominal adiposity. In this context, beer may contribute additionally to abdominal adiposity.
