Alcohol consumption, smoking habits and body fat distribution in Italian men and women aged 20-60 years.

The study was performed on 601 patients (294 males and 307 females) of a general practitioner. Alcohol intake and smoking habits were compared with other anthropometric measurements including waist-to-hip girth ratio. Patients were divided into non-smokers and smokers (subdivided into three groups according to the number of cigarettes smoked per day) and into non-drinkers and drinkers (subdivided into three groups with different alcohol intakes). Ex-smokers were excluded from the study. Analysis of covariance using age, body mass index, physical activity and menopausal status as covariates, showed that: (1) cigarette smoking is not accompanied by a specific pattern for body fat distribution; (2) waist-to-hip ratio was significantly different for the four classes of alcohol intake for women (non-drinkers: 0.809, < 11 g: 0.805, 11-20 g: 0.809, > 20 g: 0.826; F = 2.8, P < 0.05) but not for men (non-drinkers: 0.944, < 20 g: 0.934, 21-40 g: 0.940, > 40 g: 0.943; F = 0.9); (3) increased alcohol intake corresponds to an increased lipid and energy supply.
