AbstractAbstract AbstractSummary PDFSupplementary Material
The purpose of this study was to identify the trajectories and potential predictors of tobacco use during adolescence in Korea and to develop appropriate strategies for the implementation of tobacco use prevention programs.
The trajectory of tobacco use and associated predictors were analyzed for 1,169 male students from grade 6 (age 11-12) to grade 10 (age 15-16) in the Korean Children & Youth Panel Survey from 2012 to 2016.
Three trajectories of smoking experience were identified: non-smokers (class 1: n=775, 82.3%), temporary users (class 2: n=32, 3.4%), and regular users (class 3: n=135, 14.3%). When compared to non-smokers, temporary users had a higher likelihood of living with a single parent, dissatisfaction with grades, having a girlfriend, having been victimized at least once, and having at least 1 delinquent friend in grade 7 (when smoking experimentation was at its peak). Significant factors associated with regular use included having a girlfriend, committing at least 1 type of delinquent behavior, and being a non-reader. Committing at least 1 type of delinquent behavior and having at least 1 delinquent friend were associated with regular users, distinguishing them from temporary users.
Understanding why adolescents exhibit different trajectories of tobacco use by identifying the factors associated with each trajectory can contribute to the development of tailored prevention strategies and early cessation programs for adolescents.
Korean summary
2010-2016년 한국아동청소년패널에 포함된 남학생 흡연경험 분석을 통해 3개의 주요 흡연유형이 확인되었다 (비흡연자 82.3%, 일시 흡연자 3.4%, 지속 흡연자 14.3%). 한부모 가정, 학업성적에 대한 불만족, 이성친구를 사귀는 경우, 또래로부터 괴롭힘을 당한 경험, 1명 이상의 비행 친구가 있는 경우 일시 흡연자가 될 가능성이 높고, 비행 경험이 있는 경우, 이성 친구를 사귀는 경우, 독서를 하지 않는 경우 지속 흡연자가 될 가능성이 높았다. 청소년기 성장단계에 따른 흡연유형의 변화와 관련 요인에 대한 분석 결과는 청소년 대상 맞춤형 흡연예방 및 금연 프로그램 마련에 기여할 수 있을 것이다.
Key Message
In adolescence, significant life changes such as increasing academic workloads and various societal influences combined with growing recognition can affect their interest in trying smoking. The current study suggested that societal influence such as living with a single parent, dissatisfaction with grades, having been victimized at least once, and having at least 1 delinquent friend initiates smoking experimentation. Adolescents having a girlfriend, committing at least 1 type of delinquent behavior, and never reading have a greater possibility of smoking continuation for regular use. These findings might contribute to development of tailored prevention and early cessation programs for adolescents.

AbstractAbstract PDF
Stomach cancer is the second most common cancer in Eastern Asia, accounting for approximately 50% of all new cases of stomach cancer worldwide. Our objective was to compare the stomach cancer incidence rates of Asian Americans in Los Angeles with those of native Asians to assess the etiology of stomach cancer from 1988 to 2011. To examine these differences, Asian Americans (Korean, Japanese, Chinese, and Filipino Americans living in Los Angeles, California, USA) and native Asians (from Korea, Japan, China, and the Philippines) were selected for this study. Using the Cancer Incidence in Five Continents database, stomach cancer incidence rates were examined. Data from the National Cancer Registry of Korea were used for native Koreans. Between native countries, the incidence rates in Japan, China, the Philippines, and the US declined over time, but the incidence in Korea has remained constant. The incidences among Asian immigrants were lower than those among native Asians. The incidence rates of males were approximately 2 times higher than those among females in Asian countries were. The effect of immigration on stomach cancer incidence suggests that lifestyle factors are a significant determinant of stomach cancer risk. However, the incidence in Korea remains the highest of these countries
