Many students in Korea begin to use tobacco and develop a regular smoking habit before they reach adulthood. Yet, little is known about various signs contributing to the transition of the student smoking behaviors. This study used a national sample to explore and compare risk factors for smoking behaviors. Three types of smoking behaviors were defined: never smoking (in their lifetime), history of experimental smoking (ever tried but not within the last 30 days), and current smoking (at least 1 day during the last 30 days). Risk factors for experimentally starting and not continuing smoking were identified as gender, perceived health status, and friend-related stress. School type, academic performance, alcohol use, perception of harm of smoking, and close friends' smoking increased the risk of progressing from never smoking to the history of experimental smoking and current smoking. Our findings may be valuable in school health care settings in planning cessation programs.
Suicidal trends and related characteristics such as sociodemographic factors, psychological factors, and health behaviors can differ between countries. This study investigated the predictors of suicidal ideation and attempted suicide including health behaviors among American and Korean youth from two national representative data sets. In both countries, depression was the most predominant predictor to suicidal ideation and attempted suicide. Unique predictors of suicidal youth in each country were also found. In America, attempted suicide was predicted by poor body image, whereas in Korea attempted suicide was predicted by medical diagnosis such as asthma, concern about weight, and alcohol consumption. The value of our approach lies in the comparative analysis of analogous and unique characteristics of suicidal youths in these two huge data sets from different countries. These results should be helpful for school and mental health care providers to plan interventions for youth at risk of suicide to prevent suicidal completion in these nations.
The main objective of this study was to identify the risk factors and develop a decision tree model of heavy episodic drinking (HED) among adolescents. Data were obtained from a representative nationwide Korean population. Nine variables (such as last 30 days smoking, school grade, sex, depression, school achievement, level of stress, region, and economic status) were found as risk factors of HED. On the highest level of the tree root, major classification rule was played by dividing based on the last 30 days smoking and school grades. These findings should be helpful for school and mental healthcare providers to detect Korean adolescents with high possibility of HED, which will aid in planning of healthcare interventions for at-risk adolescents.
Purpose
The current study was designed to describe risk and preventive factors related to cigarette smoking among adolescents in South Korea, Vietnam, and Thailand.
Design and Methods
A cross‐sectional descriptive design was used. Student data were extracted from three national data sets, specifically the Global Youth Tobacco Survey from each country. Complex sampling multinomial logistic regression was performed to find factors related to current smoking.
Results
The prevalence of cigarette smoking was 4.7% in South Korean students, 2.8% in Vietnamese students, and 10.9% in Thai students. Students shared three risk factors related to current smoking: male sex, use of other tobacco products, and susceptibility to smoking. Additionally, only one preventive factor of cigarette smoking was found among South Korean adolescents: exposure to antitobacco advertisements. The findings suggest that personal, familial, social, and public area characteristics are associated with smoking among adolescents from these nations.
Practice Implications
These results could be useful for screening students vulnerable to cigarette smoking and the collaborative planning of interventions to prevent adolescents from smoking in these three Asian countries.
