Steep Decrease of Gender Difference in DSM-IV Alcohol Use Disorder: A Comparison of Two Nation-wide Surveys Conducted 10 Years Apart in Korea

While decreasing trend in gender differences in alcohol use disorders was reported in Western countries, the change in Asian countries is unknown. This study aims to explore the shifts in gender difference in alcohol abuse (AA) and dependence (AD) in Korea. We compared the data from two nation-wide community surveys to evaluate gender differences in lifetime AA and AD by Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV). Face-to-face interviews using the Composite International Diagnostic Interview (CIDI) were applied to all subjects in 2001 (n=6,220) and 2011 (n=6,022). Male-to-female ratio of odds was decreased from 6.41 (95% CI, 4.81-8.54) to 4.37 (95% CI, 3.35-5.71) for AA and from 3.75 (95% CI, 2.96-4.75) to 2.40 (95% CI, 1.80-3.19) for AD. Among those aged 18-29, gender gap even became statistically insignificant for AA (OR, 1.59; 95% CI, 0.97-2.63) and AD (OR, 1.18; 95% CI, 0.80-2.41) in 2011. Men generally showed decreased odds for AD (0.55; 95% CI, 0.45-0.67) and women aged 30-39 showed increased odds for AA (2.13; 95% CI 1.18-3.84) in 2011 compared to 2001. Decreased AD in men and increased AA in women seem to contribute to the decrease of gender gap. Increased risk for AA in young women suggests needs for interventions.     

Ocular changes in the mouse embryo following acute maternal ethanol intoxication

The development of the eye was investigated in the mouse embryo following a single administration of ethanol plus [3H]thymidine to the dam on day 13 of gestation. After 1 hr there was no difference in the number of labelled cells/100 micron 2 in the neural layer of the retina compared to controls, but there was an alcohol-related reduction in labelling density. After 24 hr there was an increase in the numbers of both pyknotic cells and mitotic figures, breaks occurred in the inner surface of the retina and cell debris was being extruded into the posterior chamber. At 48 hr the increase in pyknotic cells persisted, but there was less evidence of cell debris and the borders had been repaired. The estimated cell cycle time in the neural progenitor cells following maternal alcohol administration was increased 7-fold compared to controls. Morphometric analysis revealed that after 48 hr there were significant alcohol-related reductions in the width and depth of the eye, in the thickness of the neural layer and in the interocular distance. It appears that many of the ophthalmic abnormalities reported in human fetal alcohol syndrome can be produced in the mouse embryo following a single episode of acute maternal intoxication during a critical period of ocular ontogeny, and that they evolve primarily from disturbances in the normal patterns of recruitment and loss of neural progenitor cells in the developing retina.     

Enhancing Nurse Assessment of Alcohol and Drug Dependency: A Preliminary Study

The purpose of this project was to prepare nurses to provide brief interventions for clients with alcohol or other drug (AOD) dependency in order to reduce hospitalization, morbidity, and mortality. The project was a collaborative process between a major medical center and a school of nursing. Nurses were surveyed for understanding of alcohol and other drug assessment, and a day long training was provided to teach techniques of brief interventions. The short-term results included increased knowledge of nurses about AOD assessment. Long-term results indicated that 95% of patients referred to the AOD team were confirmed to have AOD problems (Dunn & Ries, 1997). This project documents the need for nurses to have more knowledge about AOD problems and brief intervention techniques.     

Adolescent alcohol initiation: A review of psychosocial risk factors

Longitudinal research studies focused on alcohol use initiation in adolescence were reviewed to determine which variables function as antecedent predictors or risk factors. Only studies that focused on time-1 abstainers were included. Classes of risk factors examined include sociodemographic, family, peer, personality, and behavioral variables. The most consistent antecedent risk factors for starting to drink in adolescence were parental and peer approval and models for drinking and drug use as well as adolescents’ own prior involvement in delinquent behavior. There was little evidence for gender differences in risk factors for alcohol use initiation. Secondary analyses of existing longitudinal data sets are encouraged to examine whether there are ethnic/racial differences in the risk factors for starting to drink and to establish those factors that serve a protective or buffering function, delaying onset of alcohol use in adolescence.
