The role of schoolmates' smoking and non-smoking in adolescents' smoking transitions: a longitudinal study

Smoking among school-going adolescents in selected secondary schools in Peninsular Malaysia- findings from the Malaysian Adolescent Health Risk Behaviour (MyaHRB) study

BACKGROUND

A multitude of studies have revealed that smoking is a learned behaviour during adolescence and efforts to reduce the incidence of smoking has been identified as long-term measures to curb the smoking menace. The objective of this study was to determine the prevalence as well as the intra and inter-personal factors associated with smoking among upper secondary school students in selected schools in Peninsular Malaysia.

METHODS

A study was carried out in 2013, which involved a total of 40 secondary schools. They were randomly selected using a two-stage clustering sampling method. Subsequently, all upper secondary school students (aged 16 to 17 years) from each selected school were recruited into the study. Data was collected using a validated standardised questionnaire.

RESULTS

This study revealed that the prevalence of smoking was 14.6% (95% CI:13.3-15.9), and it was significantly higher among males compared to females (27.9% vs 2.4%, p < 0.001). Majority of smokers initiated smoking during their early adolescent years (60%) and almost half of the respondents bought cigarettes themselves from the store. Multivariable analysis revealed that the following factors increased the likelihood of being a current smoker: being male (aOR 21. 51, 95% CI:13.1-35), perceived poor academic achievement (aOR 3.42, 95% CI:1.50-7.37) had one or both parents who smoked (aOR 1.80, 95% CI:1.32-2.45; aOR 6.50, 95 CI%:1.65-25.65), and always feeling lonely (aOR 2.23, 95% CI:1.21-4.43). In contrast, respondents with a higher religiosity score and protection score were less likely to smoke (aOR 0.51, 95% CI:0.15-0.92; aOR 0.71, 95% CI 0.55-0.92).

CONCLUSION

This study demonstrated that the prevalence of smoking among Malaysian adolescents of school-going age was high, despite implementation of several anti-smoking measures in Malaysia. More robust measures integrating the factors identified in this study are strongly recommended to curb the smoking epidemic among adolescents in Malaysia.

Prevalence and determinants of smoking initiation among school students in Bosnia and Herzegovina

BACKGROUND

Tobacco smoking amongst the young is a matter of public health concern because of the immediate and long-term health consequences associated with tobacco use, such as asthma, cancers, and cardiovascular diseases. The purpose of this study was to identify the determinants of smoking initiation among a sample of high school students in Bosnia and Herzegovina.

METHODS

The study was conducted among 198 high school students in Zvornik, Bosnia and Herzegovina, during April 2013. A self-administered, pre-tested, structured, close-ended questionnaire was used for data collection.

RESULTS

Fourth grade students mainly initiated smoking in high school (45%), while the majority of third and second grade students initiated smoking in primary school. Among students who smoke, an average duration of the smoking habit was <2 years. A multivariate analysis showed that males were 5.27 times more likely to have initiated smoking. For every unit increase in pro-smoking attitude towards smoking, students were 5.3 times more likely to have initiated smoking. Those with parents and friends who are smokers were 6.106 and 5.175 times, respectively, more likely to have initiated smoking.

CONCLUSION

This study indicates that a high proportion of 15-18 year olds in the town of Zvornik are current smokers. Gender, age, and parent and peer influence were identified as important associations with smoking. Interventions should not only be confined to the secondary school environment but they should also extend to their places of residence so that influences in the home environment and social surroundings that contribute to tobacco use are also tackled.

Social norms in the development of adolescent substance use: a longitudinal analysis of the International Youth Development Study

Identifying specific aspects of peer social norms that influence adolescent substance use may assist international prevention efforts. This study examines two aggregated measures of social norms in the school setting and their predictive association with substance (alcohol, tobacco and marijuana) use 2 years later in a large cross-national population-based cohort of adolescents. The primary hypothesis is that in Grade 7 both "injunctive" school norms (where students associate substance use with "coolness") and "descriptive" norms (where student substance use is common) will predict Grade 9 substance use. Data come from the International Youth Development Study, including 2,248 students (51.2% female) in the US and Australia attending 121 schools in Grade 7. Independent variables included injunctive norms (aggregating measures of school-wide coolness ratings of each substance use) and descriptive norms (aggregating the prevalence of school substance use) in Grade 7. Dependent variables included binge drinking and current use of alcohol, tobacco and marijuana in Grade 9. Associations between each type of school-wide social norm and substance use behaviors in Grade 9 were tested using multilevel logistic regression, adjusting for covariates. In unadjusted models, both injunctive and descriptive norms each significantly predicted subsequent substance use. In fully adjusted models, injunctive norms were no longer significantly associated with Grade 9 use, but descriptive norms remained significantly associated with tobacco and marijuana use in the expected direction. The findings identify descriptive social norms in the school context as a particularly important area to address in adolescent substance use prevention efforts.

Smoking stage relations to peer, school and parental factors among secondary school students in Kinta, Perak

BACKGROUND

To identify the prevalence of different stages of smoking and differences in associated risk factors.

MATERIALS AND METHODS

Thos longitudinal study started in February 2011 and the subjects were 2552 form one students aged between twelve to thirteen years of from 15 government secondary schools of Kinta, Perak. Data on demographic, parental, school and peer factors were collected using a self-administered questionnaire. We examined the effects of peer, school and parental factors on the five stages of smoking; never smokers, susceptible never smokers, experimenters, current smokers and ex-smokers, at baseline.

RESULTS

In the sample, 19.3% were susceptible never smokers, 5.5% were current smokers 6% were experimenters and 3.1% were ex-smokers. Gender, ethnicity, best friends' smoking status, high peer pressure, higher number of relatives who smoked and parental monitoring were found to be associated with smoking stages. Presence of parent-teen conflict was only associated with susceptible never smokers and experimenters whereas absence of home discussion on smoking hazards was associated with susceptible never smokers and current smokers.

CONCLUSIONS

We identified variations in the factors associated with the different stages of smoking. Our results highlight that anti-smoking strategies should be tailored according to the different smoking stages.

A Lifespan Developmental-Stage Approach to Tobacco and Other Drug Abuse Prevention

At least by informal design, tobacco and other drug abuse prevention programs are tailored to human developmental stage. However, few papers have been written to examine how programming has been formulated as a function of developmental stage throughout the lifespan. In this paper, I briefly define lifespan development, how it pertains to etiology of tobacco and other drug use, and how prevention programming might be constructed by five developmental stages: (a) young child, (b) older child, (c) young teen, (d) older teen, and (e) adult (emerging, young-to-middle and older adult substages). A search of the literature on tobacco and other drug abuse prevention by developmental stage was conducted, and multiple examples of programs are provided for each stage. A total of 34 programs are described as examples of each stage (five-young children, 12-older children, eight-young teens, four-older teens, and five-adults). Implications for future program development research are stated. In particular, I suggest that programming continue to be developed for all stages in the lifespan, as opposed to focusing on a single stage and that developmentally appropriate features continues to be pursued to maximize program impact.

Psychosocial factors in adolescent nicotine dependence symptoms: a sample of high school juniors who smoke daily

Cross-sectionally examined seven theory-guided psychosocial factors associated with nicotine dependence symptoms in a representative self-report survey of 794 Washington State high school junior daily smokers (93% participation). Outcomes were four nicotine dependence symptoms. Results showed that low self-efficacy for quitting smoking and being around adults who smoke were associated with a 3.48-10.35 and a 1.47-1.77 times higher odds, respectively, of each of the four nicotine dependence symptoms. These results, needing replication in a longitudinal study, suggest that interventions designed to enhance self-efficacy to quit smoking and counter adult smoking influences might reduce adolescent nicotine dependence.

No smoke without fire: The impact of future friends on adolescent smoking behaviour

OBJECTIVE

This study examined the impact of future friends and the contribution of different social influence and selection processes in predicting adolescents' smoking behaviour by extending the theory of planned behaviour (TPB). We investigated the impact of previous smoking, direct pressure from friends, descriptive norms of present and future friends, smoking-based selection of future friends, and distinguished between reciprocal and desired friends.

DESIGN

A longitudinal design with three measurements was used. METHODSL: The sample consisted of 1,475 Dutch high school students (mean age = 12.7 years) that participated as a control group in the European Smoking prevention Framework Approach study at three measurements.

RESULTS

Structural equation modelling revealed that adolescent smoking was influenced by intention, previous smoking, descriptive norms of parents and siblings, and that desired as well as reciprocal friends were selected based on similar smoking behaviour. Future friends indirectly influenced adolescent smoking through intention, as did attitude, subjective norms of parents and siblings, previous smoking, and descriptive norms of reciprocal friends and siblings.

CONCLUSIONS

The present results suggest that descriptive norms and selection of friends need to be considered as major factors explaining smoking behaviour among adolescents besides the TPB components. These insights contribute to the further refinement of smoking prevention strategies.

Adolescent psychological and social predictors of young adult smoking acquisition and cessation: A 10-year longitudinal study

OBJECTIVE

A 10-year follow-up study to test the extent to which theory-based adolescent psychological and social factors directly predict and moderate the prediction of young adult smoking acquisition and cessation.

DESIGN

A prospective community-based sample. A total of 2,970 adolescents participated in the large Washington State Hutchinson Smoking Prevention Project (HSPP) longitudinal cohort. As predictors, psychological factors (i.e., parentnoncompliance, friendcompliance, rebelliousness, achievement motivation, and thrill seeking) and social environmental factors (i.e., parent's and friend's smoking) were measured when adolescents were 17-18 years old.

MAIN OUTCOME MEASURES

As main outcome measures, smoking acquisition and cessation were assessed both at ages 18 and 28.

RESULTS

Psychological and social factors predicted 3% to 7% probability (p < .05) of smoking acquisition and a nonsignificant to 24% probability (p < .05) of smoking continuation (not quitting) in young adulthood. Both friendcompliance and rebelliousness were more powerful predictors of young adult-smoking continuation than of smoking acquisition.

CONCLUSION

First evidence that parent noncompliance, friend compliance, and a lack of achievement motivation predict smoking acquisition and (with the exception of parent noncompliance) smoking continuation in young adulthood. Including these psychological factors in future interventions designed to promote young adult smoking cessation may be useful.

Recent findings on peer group influences on adolescent smoking

This review addresses peer group influences on adolescent smoking with a particular focus on recently published longitudinal studies that have investigated the topic. Specifically, we examine the theoretical explanations for how social influence works with respect to adolescent smoking; discuss the association between peer and adolescent smoking; consider socialization and selection processes with respect to smoking; investigate the relative influence of best friends, close friends, and crowd affiliations; and examine parenting behaviors that could buffer the effects of peer influence. Our review indicates the following with respect to adolescent smoking: (a) substantial peer group homogeneity of smoking behavior; (b) support for both socialization and selection effects, although evidence is somewhat stronger for selection; (c) an interactive influence of best friends, peer groups, and crowd affiliation; and (d) an indirect protective effect of positive parenting practices against the uptake of adolescent smoking. We conclude with implications for research and prevention programs.

A social contextual analysis of youth cigarette smoking development

INTRODUCTION

We apply a social contextual perspective based on Bronfenbrenner's ecology of human development theory to understanding development of youth cigarette smoking. We examine the contributions of family, peer, school, and neighborhood contexts. Context attributes examined were derived from social learning and social control theories.

METHODS

Data are from 6,544 youth who participated in at least one of five waves of data collection between Spring 2002 and Spring 2004, 1,663 randomly selected parents who participated in one or more of three waves of data collection in the same time period; and the U.S. Census. Three-level hierarchical growth models were used to examine the contributions of time-varying measures of the four social contexts to development of smoking from age 11-17 years. Interactions between variables were examined within and between social contexts.

RESULTS

Attributes of each social context made independent contributions to adolescent smoking development; there also were significant interactions between variables from different contexts indicating joint contextual effects. Attributes of the social bond moderated exposure to models of smoking within and between the family and peer contexts.

DISCUSSION

Results suggest the value of a social contextual perspective in research on the etiology of youth smoking development as well as the utility of guidance by social learning and social control theories. While all contexts were implicated in adolescent smoking, the family and peer contexts were primarily implicated, with findings suggesting the need for consideration of interactive effects between social learning and social control variables within and between these contexts.

Psychological and social risk factors in adolescent smoking transitions: a population-based longitudinal study

OBJECTIVE

This study longitudinally investigated psychological and social risk factors consistent with the Theory of Triadic Influence (TTI) as predictors of adolescent smoking transitions.

DESIGN

Among 4218 adolescents, five psychological risk factors (i.e., parent-noncompliance, friend-compliance, rebelliousness, low achievement motivation, and thrill seeking) were assessed in 9th grade (age 14), two social influence risk factors (i.e., parents' and close friends' smoking) were assessed in Grades 3 (age 8) and 9 (age 14), respectively.

MAIN OUTCOME MEASURES

Adolescent smoking transitions occurring between the 9th and 12th (ages 14-17) grade interval.

RESULTS

The probabilities contributed by each of the five psychological risk factors to the overall probability of making a specific smoking transition were: 22% to 27% for the transition from never to trying smoking, 10% to 13% for the transition from trying to monthly smoking, and, for three of the five risk factors, 11% to 16% for the transition from monthly to daily smoking. For predicting trying smoking, the probability contributed by these psychological factors was greater than the probability contributed by each parent's and close friend's smoking. Parent-compliance had a higher contribution to the probability of trying smoking when an adolescent's parent smoked (p < .05), whereas friend-compliance had a higher contribution to the probability of trying smoking when an adolescent's friend smoked (p < .001).

CONCLUSION

These psychological and social factors have an important influence on adolescent smoking transitions. Implications for TTI and smoking prevention interventions are discussed.
