Relationship between Alcohol Purchasing Time and Alcohol Use Disorder in South Korea

Objectives Currently, time of alcohol purchase is not part of the policies to regulate alcohol consumption in South Korea. This study was conducted to determine the relationship between alcohol purchasing time and alcohol use disorder. Methods The survey for this study was conducted in geographically diverse regions of South Korea in 2012. Respondents' purchasing behaviors for both on-licensed (i.e., allows for consumption within the premises) and off-licensed (i.e., where alcohol is consumed off the premises) outlets and time of alcohol consumption were collected. Alcohol consumption patterns were examined using the Rapid Alcohol Problem Screen 4 (RAPS4). Data were also analyzed by age, gender and purchasing time. Results Results showed that among the off-licensed premises, supermarkets appear to be the most popular venue while for on-licensed premises; alcohol was generally consumed inside hotels/pubs regardless of age and gender of the purchaser. Purchasing of alcohol was highest during the day and early evening period (9:00 a.m. to 9:59 p.m.). Females are most likely to abuse alcohol than males during the early morning period and is that period after 12:00 midnight. Conclusion Analysis suggests that the survey instrument used in the International Alcohol Control Study is being used to collect data on alcohol purchasing time consumption; therefore, the potential is there to provide accurate results to contribute appropriate policy responses to reduce alcohol related-harm.
