Adolescent Smoking Susceptibility: Gender-Stratified Racial and Ethnic Differences, 1999-2018

Racial/ethnic disparities in sleep health among adolescents in South Korea: The role of substance use behaviours

AIM

To examine the relationship between racial/ethnic disparities and substance use behaviours (alcohol and tobacco use) and their impact on the sleep health of South Korean adolescents.

DESIGN

Secondary analysis of cross-sectional study data from the 2021 Korea Youth Risk Behaviour Web-based Survey dataset.

METHODS

Given that Korean society has historically linked its racial/ethnic identity to a shared bloodline, we categorized 2644 adolescents from the Korea Youth Risk Behaviour Web-based Survey based on their racial/ethnic status, determined by their parents' birthplaces. Using multiple linear regression, we investigated whether the impact of racial/ethnic disparities on sleep health (sleep duration, debt, and timing) varies depending on substance use behaviours (alcohol and tobacco use) after controlling for age, sex, household economic status, depressed mood, suicidal ideation, perceived excessive stress, and anxiety level.

RESULTS

Despite no statistical differences in sleep health and the prevalence of substance use between racial/ethnic groups, racial/ethnic minority adolescents experienced greater sleep debt than racial/ethnic majority adolescents when consuming alcohol. Moreover, racial/ethnic minority adolescents were more likely to report psychosocial distress and had lower parental education level.

CONCLUSION

Racial/ethnic minority adolescents were more vulnerable to the detrimental effects of alcohol use on sleep health compared to racial/ethnic majority adolescents. This heightened vulnerability may be attributed to the more pronounced psychosocial challenges and the lower socioeconomic status of parents in the racial/ethnic minority group.

IMPACT

Racial/ethnic disparities are concerning in South Korea, particularly since the negative effects of substance use on sleep health are intensified among racial/ethnic minority adolescents. Nurses and other healthcare providers should recognize the importance of addressing the social disadvantages linked to racial/ethnic disparities. Beyond just advocating for the cessation of substance use, it is crucial to address these underlying issues to reduce sleep disparities among South Korean adolescents.

Factors associated with intentions to quit vaping and quit attempts among Adolescents: A structural equation modeling approach

OBJECTIVES

Previous youth tobacco research has identified multiple factors relating to intentions to quit vaping and quit attempts among current e-cigarette users in adolescents. The pathways in the complex associations with vaping cessation behaviors remain unclear.

METHODS

Using data from the 2022 National Youth Tobacco Survey (NYTS) (grades 6-12), structural equation models (SEMs) are developed to examine the associations of social environment, vaping risk perceptions, e-cigarette marketing, vaping characteristics, and demographics with two outcome measures - intentions to quit vaping and past year quit attempts among current e-cigarette users.

RESULTS

The national sample of current e-cigarette users (n = 2,701) consisted of 52.7 % females, 47.0 % non-Hispanic Whites, 80.1 % high school students, and 56.2 % heterosexual individuals. Among them, 70.2 % reported intentions to quit vaping and 66.3 % reported past year quit attempts. The protective factor for quit intentions was vaping risk perceptions (p < 0.001). Risk factors included e-cigarette marketing (p = 0.04), dual use of e-cigarettes and other tobacco products (p = 0.003), vaping due to feeling anxious or stressed (p = 0.01), vaping for nicotine buzz (p = 0.002), nicotine dependence (p = 0.02), identifying as Gay or Lesbian (p < 0.001), bisexual (p = 0.03), or Hispanic (p = 0.04). Similar associations were observed with quit attempts except that e-cigarette marketing, vaping due to feeling anxious or stressed, vaping dependence, and identifying as Hispanic were not significant. Besides, high vaping frequency (p < 0.001), grade level (p < 0.001) and not sure about sexual orientation (p = 0.01) were also negatively associated with quit attempts.

CONCLUSIONS

This study provided insights into factors influencing vaping cessation outcomes among adolescent current e-cigarette users. Developing tailored vaping cessation programs based on these findings could enhance quit success.

Noncigarette Tobacco Product Use Among Smoking-Susceptible and Nonsusceptible Adolescent Never Smokers, 2009-2021

PURPOSE

Examine trends in noncigarette tobacco use among smoking susceptible and nonsusceptible adolescents from 2009-2021.

METHODS

Data came from cross-sectional samples of the National Youth Tobacco Survey (N = 183,198). Using Pierce's smoking susceptibility scale, participants were classified as either susceptible or nonsusceptible to cigarette smoking. Their use of noncigarette tobacco products was classified into four mutually exclusive categories: nonuse, noncigarette combustibles use, noncombustibles use, and noncigarette combustibles and noncombustibles dual use. We produced covariate-adjusted predicted marginal proportions of noncigarette tobacco use for 12 National Youth Tobacco Survey years, which were entered into Joinpoint trend analysis software to determine (a) trends in noncigarette tobacco use from 2009-2021 using the average annual percent changes (AAPCs) and (b) changes in each time segment using the average percent change. Models were fitted by smoking susceptibility, sex, and race/ethnicity.

RESULTS

Nonuse was lower among susceptible (vs. nonsusceptible) adolescents whereas noncigarette tobacco use was higher. Trends show significant declines in nonuse (nonsusceptible: AAPC = -0.3%) and noncigarette combustibles use (susceptible: AAPC = -12%) between 2009-2021, increases in noncombustibles use (susceptible: AAPC = 18%, nonsusceptible: AAPC = 19%) between 2009 and 2019, and steadiness in dual use. Parallel trends were observed when stratified by sex and race/ethnicity with notable increases in noncombustibles use among females and Latinos.

DISCUSSION

Noncigarette tobacco use differed by smoking susceptibility. Observed trends, especially when stratified by sex and race/ethnicity, raise concerns about tobacco use disparities among females and Latinos. Smoking susceptibility can help identify at-risk adolescents for current or future tobacco use.

Resistance to peer influence, smoking friends, cigarette and betel nut use, and gender among Pacific Islander youth

The present study examined the relationships between resistance to peer influence and cigarette and betel nut use, as well as the potential mediating role of friends who use cigarettes and betel nut, among boys and girls in Guam. This study included 673 ethnically diverse students (49% female; M age = 12.7, SD = 0.89) from eight public middle schools. The mediation analysis demonstrated that higher resistance to peer influence for both cigarette and betel nut use was associated with lower cigarette and betel nut use directly and that this association was mediated by friends who used cigarette and betel nut products. That is, low resistance to peer influence for both cigarette and betel nut use was associated with a greater number of friends who smoke and use betel nut, which was linked with more cigarette and betel nut use. The moderated mediation analysis revealed no gender difference in the indirect effect (i.e., the mediation of friends who used cigarettes and betel nut). These findings can be used to inform the design and implementation of intervention and prevention programs for at-risk youth, regardless of gender, who are vulnerable to substance use in the Pacific.

E-cigarette use and other risk factors associated with tobacco smoking susceptibility among Australian adolescents

OBJECTIVE

To explore risk factors for smoking susceptibility among Australian adolescents to inform prevention policies and programs.

METHODS

Cross-sectional survey of students aged 12-17 years who reported having never smoked (n=4,171). Bivariate associations between smoking susceptibility and a range of factors previously linked to youth smoking and smoking susceptibility were initially examined, with significant factors (p<0.05) included in a final multivariable logistic regression model.

RESULTS

Eleven percent of adolescents who had never smoked were susceptible to smoking. Smoking susceptibility was independently associated with ever use of e-cigarettes (adjusted odds ratio [AOR]=3.26, 95% confidence interval [CI]: 1.83-5.81), perceiving those who smoke to be more popular (AOR=2.87, 95% CI: 1.62-5.10), having a close friend/s who smokes (AOR=2.66, 95% CI: 1.61-4.40), not perceiving smoking one or two cigarettes occasionally as personally dangerous (AOR=2.56, 95% CI: 1.61-4.09), and having symptoms of depression (AOR=1.59, 95% CI: 1.06-2.38).

CONCLUSIONS

The strongest smoking-initiation risk factor identified was ever use of e-cigarettes, with social norms, harm misperceptions around low-rate tobacco use and mental health also linked to smoking susceptibility.

IMPLICATIONS FOR PUBLIC HEALTH

Stronger e-cigarette regulations that reduce promotion to and access by youth, as well as interventions addressing the other identified risk factors, may help prevent future smoking uptake among Australian adolescents.

Tobacco Use Patterns From Adolescence to Young Adulthood Among Latinx Youth From Rural Communities

PURPOSE

To examine patterns in adolescent and young adult tobacco use, comparing Latinx foreign-born children and children of foreign-born parents (i.e., children of immigrants(COI)) to Latinx US-born children of US-born parents (i.e., children of nonimmigrants,(CONI)) and to CONI White youth who grew up in small and rural towns.

METHODS

Data were from youth who lived in control communities that participated in a community-randomized trial of the Communities That Care prevention system. We compared Latinx CONI (n = 154) with Latinx COI (n = 316) and with non-Latinx White CONI (n = 918). We examined tobacco use in adolescence (any adolescent use, early onset, and chronic use) and young adulthood (any past-year tobacco use, any daily smoking, any nicotine dependence symptoms) with mixed-effects logistic regressions.

RESULTS

In adolescence, Latinx CONI had a higher prevalence of any and chronic tobacco use relative to Latinx COI, and of any and early onset tobacco use relative to non-Latinx White CONI. In young adulthood, Latinx CONI were more likely to report tobacco use in the past year, any symptoms of nicotine dependence, and daily smoking relative to Latinx COI; and more likely to report daily smoking relative to non-Latinx White CONI. Generation differences in young adult tobacco use were explained by chronic tobacco use in adolescence.

DISCUSSION

The study suggests targeting chronic tobacco use in adolescence to prevent disparities in tobacco outcomes among Latinx young adults from rural communities.

Asian American adolescent e-cigarette use and associated protective factors: Heterogeneity in a statewide sample

OBJECTIVES

This study characterized variation in e-cigarette use patterns and related protective factors by ethnicity among Asian American adolescents.

METHODS

Multivariable logistic regressions modelled associations between ethnic group, 6 protective factors (college aspirations, internal developmental assets, positive teacher engagement, family caring, and peer and parent anti-smoking norms), and past 30-day e-cigarette use, adjusting for covariates among 10,482 8th, 9th, and 11th grade Asian American respondents to the 2019 Minnesota Student Survey. Interaction terms (protective factor × ethnic group) were used in 6 subsequent regression models to examine whether the association between each protective factor and e-cigarette use differed as a function of ethnic group.

RESULTS

Respondents included 9.0% Indian, 0.3% Burmese, 7.9% Chinese, 2.5% Filipino, 25.0% Hmong, 3.2% Karen, 4.6% Korean, 2.7% Laotian, 8.2% Vietnamese, 7.5% other, 7.5% multi-ethnic, and 21.6% multi-racial adolescents. E-cigarettes were the predominant form of tobacco use. Laotian and multi-racial groups reported the highest e-cigarette use (16.6% and 16.3%), whereas Chinese and Asian Indians reported the lowest (4.7% and 5.0%). Strong peer anti-smoking norms, higher internal developmental assets scores, and positive teacher engagement were associated with lower odds of e-cigarette use across groups, with significant interactions for internal developmental assets by ethnicity.

CONCLUSIONS

E-cigarettes are the most prevalent tobacco product used by Asian adolescents in Minnesota, with notable heterogeneity by ethnicity. While most established protective factors appeared to function similarly for Asian adolescents, others differed, underscoring the importance of disaggregating data by ethnicity to inform the tailoring of prevention and control strategies for these ethnic groups.

Perceptions of and Experiences With Cigarette and E-Cigarette Use Among a Diverse Population of US Latino Adolescents and Young Adults

PURPOSE

To determine potential unique factors influencing cigarette and e-cigarette use in US Latino youth.

APPROACH

We conducted a qualitative study assessing cigarette and e-cigarette perceptions and experiences, including experiences with/perceptions of the products, cultural influences and influences of friends and family.

SETTING

Four online discussion boards, conducted in October 2020.

PARTICIPANTS

92 Latino youth aged 15-21 years living in the US.

METHOD

Data from the discussion groups were coded and analyzed by three trained coders using a thematic analysis approach.

RESULTS

Stress relief emerged as the dominant theme connected with both cigarettes and e-cigarettes. Apart from stress, perceptions of and experiences with the products differed. E-cigarettes were commonly viewed as trendy and cool and participants often reported using them due to curiosity and popularity. Participants commonly compared e-cigarettes to cigarettes, noting benefits of e-cigarettes. Participants also noted more negative short and long-term health effects of cigarette use, and discussed generational differences between the two products.

CONCLUSION

Findings from this study help address a dearth of research examining tobacco use among diverse groups of Latino youth. Findings indicate that despite differences in country of heritage, Latino youth are united by similar opinions about cigarettes and e-cigarettes. Additionally, they share cultural values and experiences which could be leveraged for tobacco control communications that cut across populations of Latino youth.

Gender differences in susceptibility to smoking among high school students

AIMS

To analyse the degree of susceptibility to smoking according to gender in students between 12 and 16 years of age and study the role of factors associated with gender and the extended index of susceptibility to smoking.

DESIGN

Cross-sectional study.

METHODS

Between November 2019 and March 2020, 12- to 16-year-old students were recruited from three educational centres in western Spain. Sociodemographic, environmental, social and personal variables were analysed. The value of the extended index of susceptibility to smoking was calculated, and the associations between the students' genders and smoking susceptibility were studied. Multinomial logistic regression was used to study associations between the independent variables and Expanded Susceptibility Index (ESSI) results. The roles of factors in this association were explored through mediation analysis.

RESULTS

A total of 364 students participated in the study (53% females). A total of 79.3% of females and 61.4% of males presented a medium-high level of the extended index of susceptibility. Females reported greater cigarette use (28% vs. 12.3%), hookah (19.9% vs 9.9%) and alcohol consumption (20.7% risk alcohol consumption). They obtained higher scores on the impulsivity scale in the urgency domain and the negative affect scale. Regardless of other factors, females showed more than double the smoking susceptibility (aOR: 2.05, 95% CI: 1.03-4.07, p = .041). Mediation analysis showed that gender had a total effect on the extended susceptibility index β = .023 (95% CI: 0.07-0.38, p = .01). The effect appeared to be mediated only by having smoking friends (0.08; 95% CI: 0.03-0.15, p = .001).

CONCLUSIONS

The greater susceptibility to smoking found in females may be related to a greater influence of smoking among friends.

IMPACT

These results show that smoking friends have a strong influence among adolescent females; therefore, developing preventive programmes with gender approaches aimed at reducing the influence of these environmental factors would be of interest.

Prevalence and correlates of current tobacco use and non-user susceptibility to using tobacco products among school-going adolescents in 22 African countries: a secondary analysis of the 2013-2018 global youth tobacco surveys

BACKGROUND

Our study examined the prevalence and associated factors of tobacco product use and non-users' susceptibility to using tobacco products among school-going adolescents in 22 African countries.

METHODS

We analyzed the cross-sectional 2013-2018 Global Youth Tobacco Survey (GYTS) data from 22 African countries. We conducted complex sampling descriptive and logistic regression analyses.

RESULTS

The overall prevalence of current use of any tobacco product among adolescents was 19.1%, with more males (23.7%) than females (13.7%) being current users. Zimbabwe and Morocco were the highest (47.1%) and least (12.6%) reported prevalence, respectively. Being male (AOR = 1.93;95%CI:1.61-2.32), being 16 and older(AOR = 1.37;95%CI:1.01-1.86), exposure to secondhand smoke within (AOR = 1.98;95%CI:1.69-2.32) and outside (AOR = 1.37;95%CI:1.13-1.65) the home, not knowledgeable about the harmful effect of secondhand smoke (AOR = 1.44;95%CI:1.20-1.74), exposure to tobacco industry promotion (AOR = 3.05;95%CI:2.68-3.47) and not in favour of banning smoking in enclosed places (AOR = 1.32;95%CI:1.08-1.60) were associated with current use of any tobacco product. The prevalence of the susceptibility to using tobacco products among never users of tobacco products was 12.2%, with no significant gender difference. Mozambique (24.6%) and Algeria (4.5%) had the highest and least prevalence of susceptibility to using tobacco products among never users, respectively. Exposure to tobacco industry promotion (AOR = 1.54;95%CI:1.31-1.82), those not in favour of banning smoking in enclosed places (AOR = 1.29;95%CI:1.14-1.45) and those not exposed to anti-smoking school education (AOR = 1.24;95%CI:1.06-1.46) were associated with susceptibility to using any tobacco product among never users of tobacco products.

CONCLUSION

Our study reports that tobacco use and non-user susceptibility to using tobacco products among school-going adolescents in the 22 African countries is high. As part of public health efforts, governments and other stakeholders need to fully implement anti-tobacco use campaigns, enforce a complete ban on tobacco promotion and advertising, institute educational programs for families, and anti-tobacco use education for the general public and in schools in line with WHO Framework Convention on Tobacco Control guidelines.

Tobacco 21 laws may reduce smoking and tobacco-related health disparities among youth in the U.S

The goal of our study is to understand the impact of Tobacco 21 (T21) laws on youth smoking and health equity. We conducted modified Poisson regression models using 2014-2019 Monitoring the Future data to measure the impact of attending school in a county 100% covered by a T21 law versus counties with <100% T21 coverage on past 30-day smoking participation (n = 262,632), first cigarette smoking initiation (n = 189,698), and daily smoking initiation among 8th, 10th, and 12th graders (n = 214,496), separately. Additive interactions were tested between T21 coverage and sex, race/ethnicity, parental education, and college plans. T21 coverage was associated with a lower likelihood of smoking participation among 12th graders. T21 coverage was most strongly associated with a lower likelihood of smoking participation among: Hispanic and NH (Non-Hispanic) Other/Multiracial individuals; respondents with parents who had less than a college education; and respondents who were not definitely planning on attending college. T21 laws were associated with a lower likelihood of smoking participation among 12th graders. T21 policies were most impactful for individuals disproportionately impacted by tobacco, indicating T21 laws might help reduce tobacco-related health disparities.

Current state of unhealthy living characteristics in Black/African American and Latino populations: Tobacco use

Over the past six decades, the United States has significantly improved tobacco-related health outcomes through mass efforts in policies, research, and behavioral and clinical interventions. Disparities persist, however, among communities of color who continue to suffer disproportionate rates of cardiovascular disease and other tobacco-related morbidity and mortality. In this review, we synthesize and discuss the tobacco use lifecycle across the lifespan, with special attention paid to socioecological determinants of tobacco-use behavior among Blacks and Latinos. This review summarizes the permeability of tobacco use and tobacco-related determinants across multiple levels of influence, from the individual to the societal, and highlights gaps in the tobacco control and prevention landscape. Given its continued evolution and impact on socially disadvantaged communities, we conclude with recommendations for improving current tobacco research and treatment and prevention efforts.

Socio-environmental and psychosocial predictors of smoking susceptibility among adolescents with contrasting socio-cultural characteristics: a comparative analysis

BACKGROUND

Despite a steady decline in adolescent smoking globally, it remains a prevalent risk factor for non-communicable disease. Previous research points to differences in socio-environmental and psychosocial risk factors for smoking and how they vary across different settings with disparate social and cultural characteristics. As a result, smoking rates have remained disproportionately higher in some settings while decreasing in others. This study explored the socio-environmental and psychosocial risk factors for smoking susceptibility in a high-income and upper-middle income setting.

METHODS

Cross-sectional data were obtained from 1,573 male and female adolescents aged 11-15 years who completed self-administered questionnaires in schools in Northern Ireland and Bogotá, Colombia. Using logistic regression analysis, we examined how socio-environmental and psychosocial predictors of smoking susceptibility compared across the two countries.

RESULTS

In Northern Ireland, reduced odds of smoking susceptibility were significantly associated with less family smoking (OR: 0.64, 95% CI: 0.41-1.00); having access to information about smoking in school (OR: 0.75, 95% CI: 0.59-0.96); negative attitudes towards smoking (OR: 0.35, 95% CI: 0.23-0.51); higher levels of openness (OR: 0.59, 95% CI: 0.50-0.69); and higher levels of self-reported wellbeing (OR: 0.57, 95% CI: 0.44-0.74). Increased odds of smoking susceptibility were associated with reporting less smoking of a mother (OR: 1.37, 95% CI: 1.06-1.76); higher levels of extraversion (OR: 1.40, 95% CI: 1.04-1.90); and receiving pocket money (OR: 1.20, 95% CI: 1.06-1.37). In Bogotá, reduced odds of smoking susceptibility were significantly associated with reporting less smoking among friends (OR: 0.86, 95% CI: 0.76-0.98); higher levels of self-efficacy (OR: 0.58, 95% CI: 0.40-0.83); greater perceived behavioural control to quit smoking (OR: 0.71, 95% CI: 0.56-0.90); and lower levels of truancy (OR: 0.69, 95% CI: 0.52-0.92). In Bogotá, no factors were associated with increased odds of smoking susceptibility in the final model.

CONCLUSIONS

The findings illustrate that there were differences in predictors of adolescent smoking susceptibility across the two settings. By using a comparative approach we demonstrate that smoking interventions and policies must be sensitive to the cultural and normative context within which they are implemented.

Smoking Susceptibility and Tobacco Media Engagement Among Youth Never Smokers

BACKGROUND

Susceptibility to future smoking among youth never smokers has not changed in the past 20 years, although experimental cigarette smoking has decreased. We assessed how smoking susceptibility and tobacco industry-related marketing influenced smoking initiation.

METHODS

Four waves (2013-2018) of the Population Assessment of Tobacco and Health Study data were analyzed among youth aged 12 to 17 years at wave 1 who completed wave 4. Susceptibility was assessed by 4 items (openness to curiosity, try soon, try in the next year, and if your best friend offered) and categorized into 4 levels (0 = definitely no to all; 1 = yes to 1; 2 = yes to 2; and 3 + 4 = yes to 3 or 4 susceptibility items). Multivariable logistic regression evaluated how susceptibility levels, electronic cigarette use, and tobacco-related media activity predicted future experimental (≥1 puff), current (past 30 days), or established (≥100 cigarettes) smoking.

RESULTS

Among 8899 never smokers at wave 1, 16.4% became experimental smokers, 7.6% current smokers, and 1.8% established smokers at wave 4. Black and Latino/a youth were less likely to experiment. Youth who endorsed 3 or 4 susceptibility items at wave 1 were more likely to be experimental (adjusted odds ratio [aOR] = 6.0; confidence interval [CI] = 4.8-7.4), current (aOR = 4.2; CI = 3.2-5.4), or established (aOR = 4.4; CI = 2.4-7.9) smokers at wave 4. Exposure to tobacco marketing, using tobacco-related apps, seeing social media content posted about tobacco, and ever use of electronic cigarettes also predicted experimental smoking.

CONCLUSIONS

Smoking susceptibility and exposure to tobacco industry-related marketing were predictive of cigarette smoking. Clinicians should consider screening adolescents for smoking susceptibility and tobacco-related media exposure.

E-cigarette susceptibility among U.S. middle and high school students: National Youth Tobacco Survey Data Trend Analysis, 2014-2018

Youth e-cigarette use has rapidly increased in the last few years. Susceptibility is a validated measure associated with future tobacco use. We examined trends in e-cigarette susceptibility across five years (2014-2018) of the National Youth Tobacco Survey among youth e-cigarette never users. We observed increases in overall e-cigarette susceptibility from 2014 to 2016 and decreases from 2016 to 2018. Generally, sociodemographic variables were not associated with trend effects; however, there was an interaction between linear trends with both race/ethnicity and other tobacco product (OTP) use. The percentage of youth who were susceptible to using e-cigarettes ranged from 32.9% in 2014 to 33.2% in 2018 with a high of 36.7% in 2016. We also examined the prevalence of e-cigarette susceptibility by race/ethnicity, sex, school level, OTP use, and e-cigarette harm perception. E-cigarette susceptibility was associated with race, school level, OTP ever use, and e-cigarette harm perceptions. Hispanic youth, those in high school, and OTP ever users were more likely to be susceptible to e-cigarette use compared to their counterparts across all years. E-cigarette susceptibility was most prevalent among those who perceived e-cigarettes to pose "no harm" in 2014 and "little harm" in 2018 when compared to other item response options in 2014 and 2018, respectively. This study is the first to document trends in e-cigarette susceptibility among youth. Understanding antecedents of e-cigarette use and identifying youth subgroups vulnerable to e-cigarette use is valuable to developing effective prevention efforts.

Tobacco use and other aspects related to smoking among school-going adolescents aged 13-15 years in Malaysia: Analysis of three cross-sectional nationally representative surveys in 2003, 2009 and 2016

INTRODUCTION

Periodic surveys on tobacco use patterns and other aspects of tobacco use among school-going adolescents in Malaysia provide information on the effectiveness of anti-smoking measures implemented. However, such information is limited in Malaysia. We investigated the prevalence of smoking and other related aspects among middle-secondary school students in Malaysia from the years 2003-2016 to fill this gap.

METHODS

We analyzed data from the Global Youth Tobacco Survey (GYTS) 2003, GYTS 2009, and the Tobacco and Electronic Cigarette Survey among Malaysia Adolescents (TECMA) 2016. The surveys employed multistage sampling to select representative samples of adolescents attending secondary school in Malaysia. Data were collected using a pre-validated self-administered anonymous questionnaire adopted from the GYTS.

RESULTS

Between 2003 and 2016, major changes occurred in which there were reductions in the prevalence of ever smoking, current smoking, and susceptibility to smoking. Reductions were also observed in exposure to SHS in public places and in the home. The proportion of school-going adolescents who support a ban on smoking in public places increased between 2013 to 2016, and there was a significant reduction in the proportion of respondents that were offered 'free' cigarettes by tobacco company representatives. However, there was no difference in the proportion of adolescents who initiated smoking before the age of 10 years and current smokers seeking advice to quit smoking across the time period.

CONCLUSIONS

Our study indicates that the smoking policies and measures have been effective in reducing smoking prevalence, secondhand smoke exposure, and access to cigarettes, among school-going adolescents in Malaysia. However, measures to reduce smoking initiation and increase smoking cessation need to be strengthened to reduce the burden of smoking-related diseases in Malaysia in the long-term.
