AIMS: High levels of high-density lipoprotein cholesterol (HDL-C) are not necessarily effective in preventing atherosclerotic cardiovascular disease, and cholesterol efflux capacity (CEC) has attracted attention regarding HDL functionality. We aimed to elucidate whether drinking habits are associated with CEC levels, while also paying careful attention to confounding factors including serum HDL-C levels, other life style factors, and rs671 (＊2), a genetic polymorphism of the aldehyde dehydrogenase 2 (ALDH2) gene determining alcohol consumption habit.
METHODS: A cross-sectional study was performed in 505 Japanese male subjects who were recruited from a health screening program. Associations of HDL-C and CEC levels with drinking habits and ALDH2 genotypes were examined.
RESULTS: The genotype frequencies of ALDH2 ＊1/＊1 (homozygous wild-type genotype), ＊1/＊2 and ＊2/＊2 (homozygous mutant genotype) were 55%, 37% and 8%, respectively. Both HDL-C and CEC levels were higher in ALDH2 ＊1/＊1 genotype carriers than in ＊2 allele carriers. Although HDL-C levels were higher in subjects who had a drinking habit than in non-drinkers, CEC levels tended to be lower in subjects with ≥ 46 g/day of alcohol consumption than in non-drinkers. Furthermore, CEC levels tended to be lower in ALDH2 ＊1/＊1 genotype carriers with a drinking habit of ≥ 46 g/day than non-drinkers, while for ＊2 allele carriers, CEC levels tended to be lower with a drinking habit of 23-45.9 g/day compared to no drinking habit.
CONCLUSIONS: Our results suggest that heavy drinking habits may tend to decrease CEC levels, and in the ALDH2 ＊2 allele carriers, even moderate drinking habits may tend to decrease CEC levels.
