Association between psychomotor function and ALDH2 genotype after consuming barley shochu: A randomized crossover trial.

ABSTRACT: Sustained exposure to acetaldehyde, the major metabolite of ethanol, may influence psychomotor performance even after the breath ethanol level significantly drops several hours following ethanol consumption. We examined the relationship between psychomotor function and changes in exhaled ethanol and acetaldehyde concentrations after consuming a low dose (0.33 g/kg) of barley shochu, a traditional Japanese distilled alcohol beverage, at the point when the exhaled ethanol concentrations dropped below 78,000 parts per billion (0.15 mg/L), the standard threshold for driving under the influence of alcohol in Japan. We assessed how the genetic polymorphisms of rs671 G/G homozygous (*1/*1) and G/A heterozygous (*1/*2) of ALDH2 influenced the kinetics of ethanol and acetaldehyde in exhaled air and
