Objective: The study conducted a multi-level analysis of the factors associated with the drinking behavior of single-person households in S metropolitan area. Methods: Data for individual-level characteristics were gathered from respondents who formed single-person households on the 2016~2017 Community Health Survey. Data extracted from Korea Statistics Information Services and S metropolitan census on establishments was used to identify local-level environment factors. Multi-level analysis was used to identify the effect of each level factors on drinking behaviors. Results: The study found that 39.3% of respondents were non-drinkers, 46.5% were monthly drinkers, and 14.2% were high-risk drinkers. In the analysis only using individual-level characteristics, sex, age, income level, religious activities, and friends were found to be common among drinkers and high-risk drinkers every month. Local environmental factors led to an increase in monthly drinkers and high-risk drinkers when community stores were above the median. In the multi-level analysis, only individual-level characteristics including sex, age, income level, religious activity and meeting with friends are significantly associated with the drinking behavior of single-person households, while no statistical association of local-level environmental factors observed. Conclusions: In the area that is exposed to more accessibility to alcohol, the drinking behavior of singled-person households was mainly associated with individual factors.

Background and Objectives Snoring is a condition that affects a large percentage of population and is associated with various medical and social complications. However, there are only few published reports investigating the effects of chronic snoring exposure on hearing. In the present study, we examined whether there is an association between chronic snoring noise exposure and noise induced hearing impairment not only in snorers but also in their spouses. Subjects and Method Sixty snorers and 27 spouses under the age of 55 were recruited. All participants had more than 5 years of exposure to snoring. Questionnaire for snoring and pure tone audiometry were conducted. Subjects were classified into normal hearing group and hearing impairment group. Results Forty percent of snorers and 25.9% of spouses had hearing impairment. The snorers with hearing impairment had longer duration of snoring than the snorers with normal hearing. However, there were no statistical differences in loudness of snoring between the two groups. In the spouse group, there were statistical differences in loudness of exposed snoring and in duration of snoring exposure between the hearing impairment group and the normal hearing group. Conclusion The result of this study indicated that chronic exposure to snoring noise may be associated with hearing impairment in snorers and their spouses. But in the snorers, further studies are required to identify the factors other than snoring noise associated with hearing impairment. Korean J Otorhinolaryngol-Head Neck Surg 2016;59(11):770-4
