Effectiveness of government anti-smoking policy on non-smoking youth in Korea: a 4-year trend analysis of national survey data.

ABSTRACT: OBJECTIVES:Since the Health Promotion Act was introduced in Korea in 1995, anti-smoking policies and regulations have undergone numerous revisions, and non-smoking areas have gradually been expanded. The purpose of this study was to examine the impact of a partial legislative ban on adolescent exposure to secondhand smoke using objective urinary cotinine levels in a nationwide representative sample. METHODS:Urine cotinine levels were measured in the Korea National Health and Nutrition Examination Survey from 2008 to 2011. This study was a trend analysis of 4?years of national survey data from 2197 Korean youth aged 10-18 years. Among non-smokers, the 75th percentile urinary cotinine level was estimated. We also considered the number of household smokers. RESULTS:The 75th percentile urine cotinine level of non-smokers showed a significant decreasing trend from 2008 to 2011, from 15.47 to 5.37?ng/mL, respectively. Urine cotinine did not decline significantly in non-smokers living with smokers during the study period. The results did not show a statistically significant reduction in smoking rate in adolescents from 2008 to 2011, although there was a trend towards a decrease (p=0.081). CONCLUSIONS:Based on urine cotinine levels, government-initiated anti-smoking policies have only been effective among highly exposed non-smoking adolescents during the study period. Further study needs to evaluate whether or not the legislative ban affects domestic smoking exposure.

Project description:Smoking is a global public health concern. Timor-Leste is facing a rapidly growing epidemic of tobacco use. The trend of smoking in Timor-Leste seems to be increasing and the magnitude of the problem affects people who smoke before reaching adulthood. One of the factors implicated in the continuously rising trend of smoking among young people in Timor-Leste is clearly due to unavailability of restrictive laws and regulations. Therefore, our study sought to analyze available dataset from the Global Youth Tobacco Survey (GYTS) for developing a comprehensive national smoking policy in order to lower smoking risks among young people in Timor-Leste.We conducted a secondary analysis of the 2009 GYTS in Timor-Leste. The 2009 GYTS assessed 1657 in-school students aged 13-15 years for current smoking prevalence and determinants of tobacco use. We used IBM SPSS version 21 software to analyze the data. Frequency analyses were computed to identify demographic characteristics of study participants. Bivariate logistic regression analysis was performed to examine the association between each demographic characteristic as well as each independent variable and the outcome of being current smokers.Out of 1657 in-school students, 51 % were of ages less than 15; 53 % were girls; and 45 % were in grade 2. Prevalence of current cigarette smoking was found to be 51 %. The prevalence of current smoking among in-school students increased with ages (from 46 % in less than 15 to 57 % in 15 plus). Boys were more likely to be smokers than girls (59 % versus 28 %). Significant factors positively associated with current smoking included parental smoking; closed-peer smoking; number of days people smoked in the house; having family discussion about harmful effects of smoking; being smoking in areas such as school, public places and home; and having seen cigarette advertisements on billboard.Timor-Leste has higher prevalence of cigarette smoking among minors, especially among boys. Our analysis provides evidence-based information for developing comprehensive tobacco control programs - both education and policy interventions to reduce smoking rate among young people in Timor-Leste.
