Background: This research investigated the usefulness of
heavy drinking standards of 'guidelines for moderate
alcohol drinking amount for Koreans' for diagnosis of
Diagnostic and Statistical Manual of Mental Disorders 5th
edition (DSM-5) alcohol use disorder.
Methods: This retrospective study was conducted with 976
adults who visited an health screening center in
Daejeon for health check-up in 2015. Daily drinking amount,
drinking frequency per week, and weekly drinking
amount were investigated. Using the heavy drinking criteria
of Korean guideline, participants were grouped by
age and gender and classified as normal or heavy drinkers.
The sensitivity, specificity, positive predictive value
(PPV), negative predictive value (NPV), Positive likelihood
ratio (LR+), Negative likelihood ratio (LR-), odds ratio
(OR) and Youden's Index of heavy drinking according to
Korean guideline for diagnosis of DSM-5 alcohol
use disorder were calculated.
Results: The Area under the receiver operating characteristic
(ROC) curve of a model screening DSM-5 alcohol
use disorder by weekly drinking amount were 0.812 in males
up to age 65 years and 0.931 in males over age 65
years and females respectively. The sensitivity, specificity,
PPV and NPV of Korean guideline heavy drinking group
for diagnosis of DSM-5 alcohol use disorder were 61.0%,
89.7%, 67.0%, and 87.05% respectively. The LR+, LR-,
OR and Youden's Index of those were 5.917 (4.704-7.435),
0.434 (0.379-0.497), 13.623 (9.607-19.317), and 0.507
respectively.
Conclusions: This research shows the Korean heavy drinking
standard is useful for diagnosis of DSM-5 alcohol
use disorder in Korean people.
