In previous studies, higher levels of oxidized low-density lipoprotein (ox-LDL) have been reported to increase the risk of cardiovascular disease. Furthermore, the anti-oxidative properties of red wine have been invoked to explain the paradox of low cardiovascular mortality, in spite of high-fat intake, in the French population. However, the distribution of ox-LDL-antibodies (ox-LDL-Ab) in the unselected population and its relationship with red wine consumption are unknown. This study was carried out to identify factors associated with ox-LDL-Ab, with particular emphasis on the association with wine consumption.


We performed a cross-sectional study of 551 unselected, community-dwelling older adults (aged 65 to 94 years) living in Dicomano (Italy). Ox-LDL-Ab titre was measured with an ELISA method.


In the whole study sample, ox-LDL-Ab increased with age and was unrelated to blood lipids, HbA(1c), and smoking habit. A significant inverse relationship was found between ox-LDL-Ab titre and daily wine intake, which persisted after adjusting for possible confounders or in subgroup analyses of participants who reported to drink wine or were free from significant morbidity.


These results suggest that wine affects ox-LDL-Ab titre in older populations, possibly because of its antioxidant properties.
