RESUMEN

Biomarkers can be used to assess smoking behaviour more accurately and objectively than self-report. This study assessed the association between cotinine (a biomarker of smoke exposure) and later e-cigarette use among a population who were unexposed to e-cigarettes in youth. Young people in the Avon Longitudinal Study of Parents and Children took part in the study. We observed associations between cotinine at 15 years (measured between 2006 and 2008 before the wide availability of e-cigarettes) and self-reported ever use of e-cigarettes at 22 (measured between 2014 and 2015 when e-cigarettes were widely available) using logistic regression. A range of potential confounders were adjusted for (age, sex, body mass index, alcohol use and passive smoke exposure). Additionally, we adjusted for the young people's self-reported smoking status/history to explore potential misreporting and measurement error. In a sample of N = 1,194 young people, cotinine levels consistent with active smoking at 15 years were associated with increased odds of e-cigarette ever use at 22 years (Odds Ratio [OR] = 7.24, 95% CI 3.29 to 15.93) even when self-reported active smoking status at age 16 (OR = 3.14, 95% CI 1.32 to 7.48) and latent classes of smoking behaviour from 14 to 16 (OR = 2.70, 95% CI 0.98 to 7.44) were included in the model. Cotinine levels consistent with smoking in adolescence were strongly associated with increased odds of later e-cigarette use, even after adjusting for reported smoking behaviour at age 16 and smoking transitions from 14 to 16.

RESUMEN

INTRODUCTION: Smoking during pregnancy is a primary risk factor for adverse perinatal outcomes. Although electronic cigarette (e-cigarette) use has increased, reasons for and behaviors of use are not fully understood. The purpose of this study, composed exclusively of pregnant current smokers, was to describe perceptions of health risks associated with e-cigarette use among pregnant women, describe the use patterns of pregnant dual users (defined as those who simultaneously use conventional/combustible cigarettes and e-cigarettes), and examine smoking-related behaviors between conventional-only (defined as those smoking combustible cigarettes but not e-cigarettes) and dual users. METHODS: Cross-sectional data from a larger study of pregnant conventional-only and dual users were analyzed. A brief survey measured perceptions of prenatal e-cigarette use and smoking behaviors. Analysis included descriptive statistics, bivariate analysis, and logistic and linear regression analysis. RESULTS: Among 176 pregnant smokers (38% dual users), more than one-half of participants believed e-cigarettes were harmful to women (56%) and posed harm to the fetus (53%). Among dual users, 41% used their e-cigarette daily, on average eight times per day. Eleven percent of dual users smoked a pack of cigarettes per day, compared with 5% of conventional-only smokers, and dual users scored significantly higher (p = .026) on the Penn State Cigarette Dependence Index. The most common e-cigarette liquid flavor was fruit (64%), and the most frequently reported e-cigarette nicotine concentration was 1-6 mg. CONCLUSIONS: Characterizing perceptions and behaviors of e-cigarette use during pregnancy is foundational for future research to explore the association between product use and maternal and infant outcomes.

RESUMEN

Adolescent use of electronic cigarettes (e-cigarettes) has increased dramatically, with younger and nicotine-naive adolescents starting to use these devices and use them more frequently than combustible cigarettes. In emerging evidence, it is shown that e-cigarettes are not effective in helping adult smokers quit and that youth using e-cigarettes are at risk for becoming nicotine dependent and continuing to use as adults. Important gaps in our knowledge remain regarding the long-term health impact of e-cigarettes, effective strategies to prevent and reduce adolescent e-cigarette use, and the impact of provider screening and counseling to address this new method of nicotine use.

RESUMEN

The role of nursing students as future health promoters of healthy behaviors is influenced by their attitude towards smoking. A cross-sectional study using a self-administered survey was performed to analyze smoking prevalence among undergraduate the nursing students who attend nursing faculties in 2 European countries (Spain and Portugal) during academic period 2015 to 2016. A total of 1469 subjects were surveyed (response rate of 79.8%). An 80% of the students were female with a mean age of 21.9 (4.8) years. The overall prevalence of tobacco use was 18.9%, with an average percentage of 16.2% in Portugal and 18.3% in Spain. Statistical significance was observed in relation to smoke and previous studies (16.4% vs 27.1%; P < .001). Only 1.1% of the students reported using electronic cigarette. 15.8% of smokers started smoking while at university with statistical gender and previous studies differences (P < .001). Fagerström and Richmond test showed low nicotine dependence (2.8 ±â€Š2) and moderate motivation to stop smoking (4.9 ±â€Š3), respectively. Smoking prevalence among nursing students was slightly higher than the general European population. For that reason, measures to reduce tobacco use have to be focused on students and university policies on tobacco control should be a challenge in the future.

RESUMEN

Objectives. To describe the evolution of flavored e-cigarette sales since the expansion of the JUUL brand, and to describe the effect of JUUL's November 2018 decision to self-regulate the flavors it sold in stores on flavored e-cigarette sales.Methods. We used Scantrack data on sales of e-cigarettes in the United States from January 2015 to October 2019 provided by The Nielsen Company. National sales values were aggregated monthly in 5 flavor categories (fruit, menthol/mint, sweet, tobacco, and other).Results. The expansion of JUUL sales coincided with an expansion in fruit-flavor sales through October 2018. Once JUUL withdrew fruit and sweet flavors from stores, menthol/mint came to dominate the e-cigarette market, but through 2019, a new surge in fruit-flavor sales by non-JUUL brands was observed.Conclusions. After a decline in sales following JUUL's decision to withdraw some flavored products from stores, JUUL sales recovered within weeks and surpassed their previous maximum in those same channels, as consumption shifted to the menthol/mint and tobacco flavors that remained on shelves.Public Health Implications. These trends suggest shortcomings of self-regulation and highlight the utility of government regulation.

RESUMEN

Electronic cigarette use has increased over the past decade. Its potential role in smoking cessation, in addiction and as a 'gateway' to tobacco smoking is subject to intense research. This cross-sectional study, carried out in 2013, aims to present the habits of students aged 13-15 in Greece with regard to e-cigarettes and investigate potential risk factors and the relationship between e-cigarettes, tobacco smoking and other nicotine products. It is the first such study to be carried out in Greece. The survey was based on the standardized methodology of the Global Youth Tobacco Survey. All potential associations were investigated using multiple logistic regression. In total 2.8% of the 4096 participating students were current e-cigarette users and 12.3% of them were ever users. E-cigarette use was associated with male gender, being older, current use of combustible tobacco products and e-cigarette use in the family. Ever e-cigarette use, being older, female gender and higher pocket money were associated with an increased susceptibility to tobacco smoking. E-cigarette prevalence in Greece in 2013 was similar to that of other, developed countries. The smoking and vaping habits of adolescents must be monitored in order to assess trends over time and whether any policy alterations are necessary.
