Prevalence and associated factors of smoking among chinese adolescents: a school-based cross-sectional study

BackgroundShenzhen has made great efforts to address the tobacco epidemic in the past decade. This study aims to evaluate the current status of the tobacco epidemic among adolescent in Shenzhen, China.MethodsThe multi-stage random cluster sampling method was used in the school-based cross-sectional study in 2019 and a total of 7,423 junior and high school (both senior and vocational) students were recruited. Information on cigarette use was collected by the electronic questionnaire. Logistic regression analysis was used to examine the associations between current cigarette use and associated factors. ORs with their 95% CIs were reported.ResultsThe prevalence of current cigarette use among adolescents was 2.3%, with boys (3.4%) significantly higher than girls (1.0%). Smoking rates in junior high schools, senior high schools, and vocational senior high schools were 1.0%, 2.7%, and 4.1%, respectively. The results of multivariate logistic regression analysis indicated that gender, age, parental smoking, teachers smoking in schools, friends smoking, exposure to tobacco marketing, and misconceptions about cigarette use were associated factors for adolescent smoking behaviour.ConclusionsThe prevalence of current smoking was relatively low among adolescent in Shenzhen, China. Personal characteristics, family, and school were associated with current adolescent smokers.

Patterns and associations of smoking and electronic cigarette use among survivors of tobacco related and non-tobacco related cancers: A nationally representative cross-sectional analysis

BackgroundTobacco-use among cancer survivors leads to preventable morbidity, mortality, and increased healthcare costs. We sought to explore the prevalence of smoking and e-cigarette use among survivors of tobacco and non-tobacco related cancers. MethodsA cross-sectional analysis was conducted using the 2015–2018 National Health Interview Survey. Our primary outcome was the prevalence of current cigarette smoking or e-cigarette use among adults with self-reported history of tobacco related or non-tobacco related cancer. Logistic regression analysis was to assess the association of reported cancer type with cigarette smoking or e-cigarette use. Secondary outcomes included yearly trends and dual use. ResultsA total of 12,984 respondents reported a history of cancer, representing a weighted estimate of 5,060,059 individuals with a history of tobacco-related malignancy and 17,583,788 with a history of a tobacco and non-tobacco related cancer, respectively. Survivors of tobacco-related cancers had a significantly higher prevalence of current cigarette use (18.2 % vs 9.7 %, P < 0.0001), e-cigarette use (2.7 % vs 1.6 %, P < 0.0001) and similar rates of dual use. The prevalence of cigarette smoking among all survivors increased as time increased from the year of diagnosis up to 2 years post-diagnosis (P = 0.047). Odds of reporting current cigarette smoking use was higher for survivors of tobacco-related cancers, adjusted for sociodemographic factors (OR1.69, 95 % CI 1.44−1.99). ConclusionsSurvivors of tobacco-related cancers have a higher prevalence of current cigarette smoking and e-cigarette use compared to survivors of non-tobacco related cancers. There was a sequential increase in the prevalence of cigarette use during each subsequent year from the time of a new cancer diagnosis, underscoring the need for long term tobacco cessation support among newly diagnosed adults with cancer.

Cigarette Use Among Individuals with Alcohol Use Disorders in the United States, 2002 to 2016: Trends Overall and by Race/Ethnicity.

Individuals with alcohol use disorders (AUDs) who smoke cigarettes experience greater health risks than those using either substance alone. Further, disparities exist in AUDs and smoking by race/ethnicity. Although smoking has declined in the general population, it is not known whether the smoking prevalence has changed over time for individuals with AUDs. The current study used representative U.S. data to estimate the prevalence of current cigarette use from 2002 to 2016 by AUD status and severity overall and by race/ethnicity. Data were drawn from the National Survey on Drug Use and Health, an annual cross-sectional study of U.S. individuals, from 2002 to 2016 (total analytic sample n=837,326). Cigarette smoking prevalence was calculated annually among those with and without past-year AUD and by AUD severity level (mild, moderate, severe AUD). Time trends in smoking prevalence by AUD status and severity were tested using logistic regression for the overall sample and significant interactions were subsequently stratified by race/ethnicity (non-Hispanic [NH] White, NH Black, Hispanic, NH Other). Cigarette use was persistently over twice as common among those with AUDs compared to without AUDs (2016: 37.84% vs. 16.29%). Cigarette use was also more common among those at each level of AUD severity criteria (2016: mild AUD 34.59%; moderate AUD 35.35%; severe AUD 52.23%). Approximately half of NH Black respondents with AUDs, and three-quarters of NH Black respondents with severe AUDs, reported smoking in 2016. The prevalence of smoking decreased significantly over time among respondents with and without AUDs; however, there were differences by race. There was no decline in smoking prevalence among NH Black respondents with AUDs over time in contrast to a significant decrease for every other racial/ethnic group with and without AUDs. Individuals with AUDs may need additional resources and interventions to quit smoking, especially NH Black individuals.

Moving toward a true depiction of tobacco behavior among Asian Indians in California: Prevalence and factors associated with cultural smokeless tobacco product use.

Asian Indians (AIs) in the United States exhibit disproportionate burdens of oral cancer and cardiovascular disease, which are potentially linked to smokeless tobacco. However, little is known about the use of cultural smokeless tobacco (CST) products in this population. California Asian Indian Tobacco Use Survey data from 2004 (n = 1618) were used to investigate CST prevalence among California's AIs. CST products included paan, paan masala, and gutka. A multivariable logistic regression was conducted to examine factors (socioeconomic status, acculturation measures, and religious affiliation) associated with current CST use versus never use. The current CST prevalence was 13.0% (14.0% for men and 11.8% for women). In contrast, the prevalence of current cigarette use was 5.5% (8.7% for men and 1.9% for women), and the prevalence was lower for cultural smoked tobacco (0.1% for bidis and 0.5% for hookahs). Factors associated with CST use included the following: being male, being 50 years old or older, being an immigrant, speaking an AI language at home, having a higher level of education (adjusted odds ratio [AOR] for high school/some college, 2.6; 95% confidence interval [CI], 1.1-6.5; AOR for college degree or higher, 4.0; 95% CI, 1.7-9.5), having a higher income (AOR for $75,000-$100,000, 2.5; 95% CI, 1.3-4.7; AOR for ≥$100,000, 2.6; 95% CI, 1.4-5.0), identifying as non-Sikh (AOR for Hinduism, 10.0; 95% CI, 6.0-16.5; AOR for other faiths, 10.2; 95% CI, 5.9-17.7), and disagreeing that spiritual beliefs are the foundation of life (AOR, 2.1; 95% CI, 1.2-3.5). The current CST prevalence is relatively high among California's AIs in comparison with the prevalence of smoking, with narrower differences between sexes. The association with a higher socioeconomic status is contrary to typical cigarette smoking patterns. Acculturation and religious affiliation are important factors associated with current use. Health care providers and policymakers should consider such determinants for targeted interventions. Cancer 2018;124:1607-13. © 2018 American Cancer Society.

Population-Based Study of Tobacco Use Among People Living With HIV in Puerto Rico

ABSTRACTBackground: Despite substantial advances in the era of highly active antiretroviral therapy, HIV-positive persons are at high risk of tobacco-related disease and mortality. This study describes the prevalence and sociodemographic factors associated with current tobacco use among HIV-positive men and women 18 years and older receiving HIV care in Puerto Rico. Methods: Data from the 2009 Medical Monitoring Project (MMP) was used. A three-stage sampling design was conducted to obtain annual cross-sectional probability samples of HIV-infected adults in care. Factors associated with current tobacco use were identified using logistic regression models. All analyses were performed using STATA version 11.0. Results: The estimated prevalence of current cigarette use among the population was 29.0% (95%CI: 23.5%–35.2%), daily smoking was reported in 76.7% of them. Multivariate logistic regression models, showed that male drug users (injected and noninjected) were up to nine times more likely to be current smokers (OR = 9.9; 95%CI = 3.1, 31.5) as compared to nonusers. Conclusion: Findings highlight the need for smoking cessation strategies in this population, particularly among male HIV+ drug users.

Multilevel analysis of school anti-smoking education and current cigarette use among South African students.

IntroductionSouth Africa (SA) implemented the Global Youth Tobacco Survey (GYTS) four times between 1999 and 2011. Data from the four surveys indicated that downward trends in cigarette use among students may have stalled. Understanding the effect of school anti-smoking education on current smoking among students within schools and variability across schools may provide important insights into policies aimed at preventing or reducing tobacco use among students. The objective was to assess the student- and school-level effects of students' exposure to school anti-smoking education on current cigarette use among the study population using the most recent wave of GYTS data in SA (2011).MethodsAn analytic sample of students 13-15 years of age was selected (n=3,068) from the SA GYTS 2011. A taxonomy of two-level logistic regression models was fit to assess the relationship of various tobacco use, control, and exposure predictor variables on current cigarette smoking among the study population.ResultsAt the student-level in the full model, secondhand smoke (SHS) exposure, peer smoking, and ownership of a promotional item were significantly associated with higher risk of current smoking. At the school-level in the full model, average exposure to peer smoking was associated with significant increases in the prevalence of current cigarette use, while average family anti-smoking education was significantly associated with decreases in the outcome variable. School anti-smoking education was not a statistically significant predictor at the student- or school-levels.Conclusionin this study, exposure to school anti-smoking education had no association with current cigarette smoking among the study population. Consistent with previous studies, having peers that smoked was highly associated with a student being a current smoker. Interestingly, at the school-level in the multilevel analysis, schools with higher rates of average family anti-smoking education had lower prevalence of current smoking. This finding has potential implications for tobacco control in SA, particularly if the school-level, family-centered protective effect can be operationalized as a prevention tool in the country's tobacco control program.

E-cigarettes, Cigarettes, and the Prevalence of Adolescent Tobacco Use.

Adolescent e-cigarette use has increased rapidly in recent years, but it is unclear whether e-cigarettes are merely substituting for cigarettes or whether e-cigarettes are being used by those who would not otherwise have smoked. To understand the role of e-cigarettes in overall tobacco product use, we examine prevalence rates from Southern California adolescents over 2 decades. The Children's Health Study is a longitudinal study of cohorts reaching 12th grade in 1995, 1998, 2001, 2004, and 2014. Cohorts were enrolled from entire classrooms in schools in selected communities and followed prospectively through completion of secondary school. Analyses used data from grades 11 and 12 of each cohort (N = 5490). Among 12th-grade students, the combined adjusted prevalence of current cigarette or e-cigarette use in 2014 was 13.7%. This was substantially greater than the 9.0% adjusted prevalence of current cigarette use in 2004, before e-cigarettes were available (P = .003) and only slightly less than the 14.7% adjusted prevalence of smoking in 2001 (P = .54). Similar patterns were observed for prevalence rates in 11th grade, for rates of ever use, and among both male and female adolescents and both Hispanic and Non-Hispanic White adolescents. Smoking prevalence among Southern California adolescents has declined over 2 decades, but the high prevalence of combined e-cigarette or cigarette use in 2014, compared with historical Southern California smoking prevalence, suggests that e-cigarettes are not merely substituting for cigarettes and indicates that e-cigarette use is occurring in adolescents who would not otherwise have used tobacco products.

PO-0002 Prevalence Of Smoking Among Adolescents In Saudi Arabia: The Relationship To School Connectedness

<h3>Introduction</h3> Initiation of smoking behaviour during adolescence is associated with many negatives. In Saudi Arabia, the prevalence of teen smoking is not well understood. 2013 WHO Health Report on Global Tobacco Epidemic indicates the prevalence of current cigarette use among youth as 6% (Boys: 13%, Girls: 5%). This paper presents data from a larger study of adolescents’ health developed for Saudi youth in Riyadh. The purpose of which is to describe the smoking behaviours of adolescent boys and girls aged 14–19. <h3>Methodology</h3> A health survey was developed for Saudi youth after extensive literature review. The survey focused on adolescents’ behaviours and attitudes, including questions about smoking and tobacco use. A total of 1430 Adolescents from 12 schools participated in the study. 54.8% were male. Univariate descriptive statistics were examined. data was analysed by chi-square tests using SPSS Statistics (Version 21) software; p-values &lt; 0.05 were considered statistically significant. <h3>Results</h3> 20% reported having ever smoked a whole cigarette. Among the smokers half smoked their first cigarette at 13 years. Students who reported ever smoking had a significantly lower mean school connectedness score compared to students who never smoked (t = 3.03, p = 0.003). (SD)=2.77(.67) vs. Never smoked=2.9(62), t. 50% of students had smokers in the family <h3>Conclusion</h3> The most important implication of this study is finding ways to improve the school connectedness which will inversely affect the prevalence of smoking among adolescents. Policy makers have to consider this seriously Detailed surveying of smoking behaviours at regular intervals is likely to provide a more thorough perspective.

Sustained decreases in risk exposure and youth problem behaviors after installation of the Communities That Care prevention system in a randomized trial.

To test whether the Communities That Care (CTC) prevention system reduced levels of risk and adolescent problem behaviors community-wide 6 years after installation of CTC and 1 year after study-provided resources ended. A community randomized trial. Twenty-four small towns in 7 states, matched within state, randomly assigned to control or intervention condition in 2003. A panel of 4407 fifth-grade students was surveyed annually through 10th grade from 2004 to 2009. A coalition of community stakeholders received training and technical assistance to install CTC, used epidemiologic data to identify elevated risk factors and depressed protective factors in the community, and implemented programs to address their community's elevated risks from a menu of tested and effective programs for youths aged 10 to 14 years, their families, and schools. Levels of risk and incidence and prevalence of tobacco, alcohol, and other drug use; delinquency; and violent behavior by grade 10. Mean levels of targeted risks increased less rapidly between grades 5 and 10 in CTC than in control communities and were significantly lower in CTC than control communities in grade 10. The incidence of delinquent behavior, alcohol use, and cigarette use and the prevalence of current cigarette use and past-year delinquent and violent behavior were significantly lower in CTC than in control communities in grade 10. Using the CTC system can produce enduring reductions in community-wide levels of risk factors and problem behaviors among adolescents beyond the years of supported implementation, potentially contributing to long-term public health benefits. clinicaltrials.gov Identifier: NCT01088542.

Cigarette Use Among High School Students'United States, 1991–2005

Cigarette use is the leading preventable cause of death in the United States. A national health objective for 2010 is to reduce the prevalence of current cigarette use among high school students to </=16% (objective no. 27-2b). To examine changes in cigarette use among high school students in the United States during 1991-2005, CDC analyzed data from the national Youth Risk Behavior Survey (YRBS). This report summarizes the results of that analysis, which indicated that, although lifetime, current, and current frequent cigarette use was stable or increased during the 1990s and then decreased significantly from the late 1990s to 2003, prevalence was unchanged during 2003-2005. To achieve the 2010 objective, the downward trend in youth smoking must resume.
