Longitudinal study of adolescents' attempts to promote and deter friends' smoking behavior

New Zealand adolescents' discouragement of smoking among their peers

OBJECTIVE

This study examines the extent to which young people are acting as 'agents of change' in discouraging smoking among their peers.

METHODS

This study used data from a survey of 2,919 New Zealand secondary school students who participated in the 2014 national Youth In-depth Survey. Relevant questions were used to assess the extent to which students engaged in behaviours to discourage or promote smoking among their peers.

RESULTS

About half of all students reported some form of behaviour discouraging others from smoking, while only one in ten reported encouraging smoking. Discouragement was associated with non-smoking or lower levels of smoking, having more friends who smoked, and exposure to more health promotion messages about not smoking. Māori and Pacific young people also reported more discouraging behaviours.

CONCLUSIONS

The results highlight the positive impact that young people can have on discouraging smoking among their peers. Implications for public health: The findings of this study point to encouraging and training young people as 'agents of change' to spread the smokefree message.

[Tobacco consumption and its relationship to the level of regular physical activity and physical fitness in adolescents from the region of Murcia (Spain)]

This study looks at the relationship between tobacco consumption and the physical activity and fitness levels of adolescents. In a sample of 533 adolescents, both a questionnaire to obtain information regarding tobacco consumption and the International Physical Activity Questionnaire for information on physical activity were implemented; a battery of tests to assess physical fitness were also applied. Tobacco consumption was significantly higher in females (32.5%) than in males (25.7%). Levels of physical activity in both males and females were significantly associated with tobacco consumption (p<0.0005). Moreover, subjects who consumed tobacco showed lower overall averages in physical fitness tests than those who did not (4.26 vs. 5.77 in males and 4.54 vs. 6.71 in females). Tobacco consumption is therefore shown to be related to lower levels of physical activity and physical fitness in adolescents.

Adolescent (Mis)Perceptions About Nicotine Addiction: Results From a Mixed-Methods Study

PURPOSE

Despite evidence that adolescents become addicted to nicotine even after limited use, adolescents believe they can experiment with or smoke cigarettes for a few years and easily quit. The goal of this study was to examine adolescents' understanding of the definition and process of nicotine addiction using a mixed-methods approach.Method A total of 367 adolescents with and without smoking experience rated the perceived risk for addiction, still being a smoker in 5 years, and ability to quit smoking. A subsample of adolescents (N= 41) were interviewed about their conceptualization and understanding of nicotine addiction. Within-participants analyses of variance were conducted to assess differences in perceptions of addiction across the three scenarios; thematic analyses of interviews were conducted to assess adolescents' understanding of addiction.Results Adolescents rated their perceived risk for addiction, still being a smoker in 5 years, and ability to quit as significantly different from one another for three different scenarios (F= 7.81, 47.78, and 70.27, respectively;p< .001). Seven themes describing how youth conceptualize and understand addiction emerged from the interview data, including skepticism and uncertainty about addiction, how smoking makes a person feel, and family and friends' experiences.

CONCLUSION

While adolescents have received the message that cigarettes are addictive, they are uncertain regarding the definition of addiction and have not recognized that addiction means experiencing difficulty quitting and continuing to smoke longer than expected. Findings suggest the need for comprehensive messaging regarding nicotine addiction in educational, clinical, and intervention settings and for product warning messages aimed at reducing and preventing tobacco use.

Conditional risk assessment of adolescents' electronic cigarette perceptions

OBJECTIVES

To adapt an established instrument for measuring adolescents' cigarette-related perceptions for new application with electronic cigarettes (e-cigarettes).

METHODS

In this exploratory study, 104 male high school students (40% tobacco ever-users) estimated the probability of potential e-cigarette risks (eg, lung cancer) or benefits (eg, look cool). We calculated associations between risk/benefit composite scores, ever-use, and use intention for e-cigarettes, and analogously, for combustible cigarettes.

RESULTS

E-cigarette ever-use was associated with lower perceived risks, with adjusted differences versus never-users greater for e-cigarettes than for cigarettes. Risk composite score was inversely associated, and benefit score positively associated, with e-cigarette ever-use and use intention.

CONCLUSION

Conditional risk assessment characterized adolescents' perceived e-cigarette risk/benefit profile, with potential utility for risk-perception measurement in future studies.
