Background/Objectives: It has been reported that alcohol stimulates appetite. We aimed to establish the association between leptin, as a major food intake regulating factor, and alcohol intake in patients with chronic manifest coronary artery or cerebrovascular disease.
Subjects/Methods: A cross-sectional study of 820 subjects after acute coronary syndrome, coronary revascularization or after first ischemic stroke (the Czech part of EUROASPIRE III surveys). Leptin concentrations were evaluated among predefined categories of reported weekly alcohol intake: abstainers, light drinkers (up to 2 drinks weekly, 1-44 g of pure alcohol), mild regular drinkers (3-14 drinks weekly, 45-308 g) and moderate or heavy drinkers (more than 15 drinks, >= 309 g of alcohol).
Results: Leptin showed a clear negative trend among the alcohol intake categories. Mild regular drinkers showed significantly lower leptin levels (9.3(8.2) ng/ml) compared with abstainers (18.7(18.7) ng/ml, P<0.0001) and light occasional drinkers (14.2(17.8) ng/ml, P = 0.00064). The negative association between leptin and alcohol intake as a dependent variable remained significant even after adjustment for potential confounders in multiple linear regression analysis (P = 0.00032).
Conclusions: Drinking of small amounts of alcohol was, in our setting, associated with decreased serum leptin concentration, with a possible benefit in terms of cardiovascular risk.
