E-cigarette and combustible cigarette cessation patterns, reasons, and methods among adolescents, young adults, and adults.

Research is limited regarding adolescents' and young adults' (AYA) patterns, methods of, and reasons for cigarette or e-cigarette cessation. Further, while adults may try to use e-cigarettes to quit combustible cigarettes, little is known about how adults then quit e-cigarettes. This study utilizes a national, cross-sectional online survey of 6131 diverse participants aged 13-40 years to examine reasons for quitting e-cigarettes or cigarettes, quit methods, and quit attempt outcomes among AYAs and adults. In our sample, 3137 (51.2%) had ever used an e-cigarette, of whom 2310 (37.7%) were aged 13-24 years and 827 (13.5%) were 25-40 years old; 2387 (38.9%) had ever used a combustible cigarette (1440 [23.5%] were 13-24 years old and 947 [15.4%] were 25-40 years old). Among e-cigarette ever-users, 39.4% of 13-24-year-olds intended to quit in the next 6 months, and 36.9% had a serious plan for quitting in the next 30 days; 25.2% wanted to decrease the amount they used while 34.8% wanted to quit completely. Similar rates were found among e-cigarette ever users aged 25-40 years, as well as past 30-day e-cigarette users, cigarette ever-users, and past 30-day cigarette users across all ages. "Cold turkey" (41.0%) followed by "tried to cut down slowly by vaping/smoking less often or fewer puffs" (25.5%) was the most common quit method among e-cigarette ever-users and cigarette ever-users of all ages. Further study of effective tobacco cessation methods to help both AYAs and adults successfully quit nicotine, whether from cigarettes or e-cigarettes, is urgently needed.

JUUL and other e-cigarettes: Socio-demographic factors associated with use and susceptibility in California.

This study examined which socio-demographic factors are associated with susceptibility (lack of commitment to avoid future use), past-12-month and past-30-day use of JUUL and other e-cigarettes, and reasons for and against using JUUL. An online survey of 3,075 Californians ages 15-29, including 24.3% who identified as LGBTQ, were recruited via social media in January-March 2019. Multi-level weighted logistic regression models suggest that LGBTQ participants were more likely to be susceptible to JUUL [AOR = 2.11 (1.60, 2.79) (parentheses include 95% Confidence Intervals)] and other e-cigarettes [AOR = 2.31 (1.75, 3.05)], and more likely to use JUUL [AOR = 1.27 (1.02, 1.58)] and other e-cigarettes [AOR = 1.66 (1.35, 2.05)] in the past 12 months. Susceptibility to using JUUL was more likely among adolescents (ages 15-17) [AOR = 1.72 (1.30, 2.28)] and young adults (ages 18-20) [AOR = 1.26 (1.00,1.58)] than adults (ages 21-29). At the community level, living in jurisdictions with higher median household income was associated with a higher likelihood of being susceptible to using JUUL and other e-cigarettes. Compared to non-Hispanic Whites, Asian/Pacific Islanders were less likely to use JUUL [AOR = 0.68 (0.54, 0.86)] and other e-cigarettes [AOR = 0.60 (0.48, 0.76)] in the past 12 months. Past-30-day JUUL use was more likely among males than females [AOR = 1.44 (1.11, 1.88)]. Common reasons for using JUUL were: friends' use, flavors, "safer" than cigarettes, no one will notice, and nicotine rush is greater than other devices. Common reasons against using JUUL were: harmful to self/others, contains nicotine and is addictive. E-cigarette prevention and cessation efforts should include tailored messaging for people who identify as LGBTQ and reinforce reasons for not vaping nicotine.

Self-reported changes in cannabis vaping among US adolescents and young adults early in the COVID-19 pandemic.

Cannabis vaping may increase susceptibility to COVID-19 infection and related outcomes; however, little is known about the impact of the pandemic on cannabis vaping among US young populations. This study examined self-reported changes in cannabis vaping since the pandemic and factors associated with changes. A national, cross-sectional survey was conducted among 4,351 US adolescents and young adults (13-24 years old) in May 2020. Of those, 1,553 participants who reported ever vaping cannabis were included in the analytic sample. Binary outcome was self-reported increase in cannabis vaping (more hours/times of vaping in a day) vs. no change/quitting/reducing/switching. Weighted logistic regression examined associations between independent variables (i.e., risk perceptions of vaping, cannabis dependence, and stress/anxiety) and the outcome, controlling for sociodemographic factors. Overall, 6.8% reported increasing cannabis vaping since the pandemic, 37.0% quitting or reducing vaping in general, and 42.3% no change. Participants were more likely to report increased cannabis vaping if they perceived "Vaping is safer than smoking cigarettes" (Adjusted Odds Ratio [AOR] = 3.66; 95%CI = 1.43-9.38), reported more dependence on cannabis vaping (AOR = 1.59; 95%CI = 1.11-2.27), and were female (AOR = 2.80; 95%CI = 1.23-6.36). Those perceiving "Vaping cannabis can cause lung injuries" were less likely to increase cannabis vaping (AOR = 0.37; 95%CI = 0.18-0.76). Findings indicate that adolescent and young adult ever-cannabis vapers were more likely to report decreasing vaping generally than increasing cannabis vaping and most did not change use during the early pandemic. Educational campaigns should address potential health risks of cannabis vaping and focus on lung health to reduce use among young people during and following the pandemic.

Physical Activity Among Adolescents in India: A Qualitative Study of Barriers and Enablers.

Inadequate physical activity (PA) levels are reported in Indian youth, with lowest levels among adolescents, particularly girls. We aimed to identify barriers to and enablers of PA among school children in New Delhi and examine potential differences by gender and school type (government vs. private). A total of 174 students (private school students = 88, 47% girls; government school students = 86, 48% girls) aged 12 to 16 years from two Delhi schools participated in 16 focus group discussions (FGDs) conducted by bilingual moderators. We conducted FGDs separately for girls and boys, for students in Grades VIII and IX, and for private and government schools. We conducted FGDs among government school students in Hindi and translated the transcriptions to English for analysis. We coded transcriptions using a combination of inductive and deductive approaches, guided by the "youth physical activity promotion model." We identified various personal, social, and environmental barriers and enablers. Personal barriers: Private school girls cited body image-related negative consequences of PA participation. Social barriers: Girls from both schools faced more social censure for participating in PA. Environmental barriers: Reduced opportunity for PA in schools was commonly reported across all participants. Personal enablers: All participants reported perceived health benefits of PA. Social enablers: Several participants mentioned active parents and sports role models as motivators for increasing PA. Few environmental enablers were identified. This study highlights the need for further investment in physical activity within schools and for gender-sensitive policies for encouraging PA participation among adolescents in India.
