Factors Related to Regional Variation in the High-risk Drinking Rate in Korea: Using Quantile Regression

Abstract

Objectives: This study aimed to identify regional differences in the high-risk drinking rate among yearly alcohol users in Korea and to identify relevant regional factors for each quintile using quantile regression. Methods: Data from 227 counties surveyed by the 2017 Korean Community Health Survey (KCHS) were analyzed. The analysis dataset included secondary data extracted from the Korean Statistical Information Service and data from the KCHS. To identify regional factors related to the high-risk drinking rate among yearly alcohol users, quantile regression was conducted by dividing the data into 10%, 30%, 50%, 70%, and 90% quantiles, and multiple linear regression was also performed. Results: The current smoking rate, perceived stress rate, crude divorce rate, and financial independence rate, as well as one’s social network, were related to the high-risk drinking rate among yearly alcohol users. The quantile regression revealed that the perceived stress rate was related to all quantiles except for the 90% quantile, and the financial independence rate was related to the 50% to 90% quantiles. The crude divorce rate was related to the high-risk drinking rate among yearly alcohol users in all quantiles. Conclusions: The findings of this study suggest that local health programs for high-risk drinking are needed in areas with high local stress and high crude divorce rates.

Prevalence, awareness, and treatment of depression among community-dwelling stroke survivors in Korea

“…Participants were classified as either current smokers or non-smokers (never or past smokers), according to their smoking status. For the drinking status, participants were categorized into risky drinkers (those who drank ≥ 2 times/week, with an average of ≥ 5 drinks/occasion for men and ≥ 7 drinks/occasion for women) and non-risky drinkers (those who drank less alcohol than risky drinkers) 41 . The physical activity status of participants was classified according to the Physical Activity Guidelines for Americans 2nd edition 42 , which recommends that adults engage in at least 150 min of moderate-intensity aerobic physical activity, 75 min of vigorous-intensity aerobic physical activity, or an equivalent combination of moderate and vigorous-intensity activity.…”

Data resource profile: the Korean Community Health Status Indicators (K-CHSI) database

“…Previous studies on community-level health have mainly used KCHS data. A study on factors related to regional variation in high-risk drinking rates found that the current smoking rate, perceived stress rate, crude divorce rate, and financial independence rate of all municipalities were related to the high-risk drinking rate [ 18 ]. Community-level data may be used to evaluate the effects of specific health policies.…”
