The role of family factors and school achievement in the progression of adolescents to regular smoking

Parental Anti-Smoking Encouragement as a Longitudinal Predictor of Young Adult Cigarette and E-cigarette Use in a US National Study

INTRODUCTION

Young adulthood is a critical period for the adoption of risk behaviors like tobacco use. Protective factors in adolescence may promote a tobacco-free transition to young adulthood. We examine associations between the frequency of parental anti-smoking encouragement in adolescence and cigarette and e-cigarette use in young adulthood.

AIMS AND METHODS

We analyzed data from Waves 1 (2009-2010, 10th grade, mean age = 16.2 years) and 5 (2013-2014 mean age = 20.3 years) of the US nationally representative NEXT Generation Health Study (n = 1718). At Wave 1, participants reported how often their parents or guardians encourage them to not smoke cigarettes (1 = Rarely or Never, 7 = Frequently). We used separate weighted multiple logistic regression models to model Wave 5 past 30-day cigarette and e-cigarette use as functions of the frequency of parental anti-smoking encouragement at Wave 1, adjusting for sociodemographic and parenting factors, initial substance use, and peer tobacco use.

RESULTS

The average frequency of parental encouragement to not smoke cigarettes was fairly high (mean = 5.35). At Wave 5, 24.7% and 14.2% of respondents reported cigarette and e-cigarette use in the past 30 days, respectively. Greater frequency of parental anti-smoking encouragement was associated with lower odds of subsequent cigarette smoking (adjusted odds ratio 0.91, 95% confidence interval 0.83, 0.99) but its association with e-cigarette use was not significant (adjusted odds ratio 0.93, 95% confidence interval 0.84, 1.04).

CONCLUSIONS

The longitudinal negative association between anti-smoking encouragement and cigarette use suggests that parental anti-tobacco communication could be a long-term protective factor against young adult tobacco use. Our findings may also suggest the importance of product-specific messages in the evolving tobacco use landscape.

IMPLICATIONS

This study builds upon prior investigations of parenting in adolescence as a protective factor against young adult risk behavior. We isolate the frequency of anti-smoking encouragement during adolescence as an actionable factor distinct from other parenting variables. Our findings also suggest that message specificity may be an important factor in parental anti-tobacco communication as youth and young adult tobacco use becomes increasingly dominated by e-cigarettes.

Características biopsicosociales relacionadas con el consumo de cigarrillo y la intención de cesación en fumadores en un entorno universitario

Introducción. El tratamiento de la dependencia tabáquica requiere la comprensión de múltiples factores que determinan los patrones de consumo y la posibilidad de lograr un cambio conductual. Objetivo. Establecer las características biopsicosociales asociadas con el consumo de cigarrillo y la intención de cesación de los usuarios de un programa interdisciplinario para dejar de fumar en un entorno universitario.Materiales y métodos. Estudio descriptivo transversal. Se revisaron las historias clínicas de 134 usuarios del programa que completaron la fase de evaluación.Resultados. 56.7% de los participantes presentó un grado leve de tabaquismo; además, 67.2% tuvo una baja dependencia a la nicotina. Se encontró una tamización positiva para ansiedad y depresión en el 62.7% y 34.3% de la muestra, respectivamente. La mayoría de sujetos tenía por lo menos un amigo fumador (91%) (n=122) y había realizado al menos un intento previo de cesación (85.1%) (n=114); los individuos con riesgo de desarrollar ansiedad presentaron un mayor consumo diario de cigarrillos (Kruskal-Wallis p=0.041) que aquellos que no estaban en riesgo.Conclusiones. Diferentes aspectos personales, familiares y contextuales determinan la posibilidad de iniciar, continuar y/o recaer en el consumo de cigarrillos, por lo que la implementación de intervenciones efectivas exige la comprensión integral de los factores implicados en su consumo y en la intención de cesación.

Parental involvement and adolescent smoking in vocational setting in Finland

The present study examined whether parental involvement in their adolescents' lives is associated with adolescent smoking in a vocational school setting when controlling for socioeconomic background and parental smoking. The study was conducted in spring 2013 and involved 34 776 Finnish vocational school students (mean age 17.6 years). The data were analyzed using multinomial regression. The results showed that lower parental involvement was significantly associated with adolescent daily smoking in both genders and with occasional smoking in girls. Parental daily smoking predicted adolescent daily smoking, and this association was also seen for those adolescents whose mother and father had quitted smoking. Furthermore, our results indicate that mothers' smoking may be more influential on adolescents' smoking than fathers' smoking. Multivariate analysis showed that living in a nuclear family or alternately with both parents in two homes decreased daily smoking in both genders compared to living in other family arrangements.

What parents can do to keep their children from smoking: A systematic review on smoking-specific parenting strategies and smoking onset

AIM

To provide a systematic overview of longitudinal studies on different smoking-specific parenting practices (i.e., perceived parental norms and influences, smoking-specific monitoring, availability of cigarettes at home, household smoking rules, non-smoking agreements, smoking-specific communication, and parental reactions) as useful tools in the prevention of youth smoking.

METHOD

MEDLINE and PsychINFO search identified 986 studies published from 1990 to December 2016. Two independent researchers identified eligible studies. Study quality was assessed using Newcastle Ottawa Scale (NOS).

RESULTS

The systematic search resulted in 1 to 14 longitudinal studies per parenting practice. Studies scored between 4 and 9 on the NOS, indicating an overall moderate quality. The results of complete smoking house rules showed a preventive effect on smoking onset. Furthermore, availability of cigarettes, frequency and quality of communication, parental reaction (i.e., conflict engagement) and norms showed significant and non-significant effects. Significant results were in line with expectations: availability of cigarettes and frequent communication about smoking predicted smoking, whereas a high quality of communication, negative reactions or punishments and setting norms by parents showed a preventive effect. No effects were found for non-smoking agreements. The number of studies was too limited to draw conclusions about other parenting strategies. More research on (1) reliable and valid instruments, (2) other stages of smoking in addition to onset, and (3) potential moderators and mediators is warranted.

CONCLUSION

While evidence supports the effectiveness of smoking-specific parenting, further research is required.

Factores pro­tectores: a) creer que es dañino (RM=0.3, IC95% 0.14-0.65), GF: rechazo a convivencia con fumadores; b) comunicación con familia (RM=0.5, IC95% 0.36-0.91), GF: apelar al auto-cuidado; c) Considerarse joven para fumar (RM=0.2, IC95% 0.12-0.43), GF: conocimientos sobre daños y percepción de riesgo. Conclusión. Se deben fortalecer destrezas psicosociales positivas y el cumplimiento de legislación de protección a jóvenes.

Sport and scholastic factors in relation to smoking and smoking initiation in older adolescents: a prospective cohort study in Bosnia and Herzegovina

OBJECTIVE

Sport and scholastic factors are known to be associated with cigarette smoking in adolescence, but little is known about the causality of this association. The aim of this study was to prospectively explore the relationships of different sport and scholastic factors with smoking prevalence initiation in older adolescents from Bosnia and Herzegovina.

METHODS

In this 2-year prospective cohort study, there were 872 adolescent participants (16 years at baseline; 46% females). The study consisted of baseline tests at the beginning of the third year (September 2013) and follow-up at the end of the fourth year of high school (late May to early June 2015). The independent variables were scholastic and sport-related factors. The dependent variables were (1) smoking at baseline, (2) smoking at follow-up and (3) smoking initiation over the course of the study. Logistic regressions controlling for age, gender and socioeconomic status were applied to define the relationships between independent and dependent variables.

RESULTS

School absence at the baseline study was a significant predictor of smoking initiation during the course of the study (OR 1.4, 95% CI 1.1 to 1.8). Those who reported quitting sports at baseline showed an increased risk of smoking at the end of the study (OR 1.4, 95% CI 1.1 to 2.0) and of smoking initiation (OR 1.8, 95% CI 1.3 to 2.0). Adolescents who reported lower competitive achievements in sport were at a higher risk of (1) smoking at baseline (OR 1.5, 95% CI 1.1 to 2.1), (2) smoking at follow-up (OR 1.5, 95% CI 1.1 to 2.1) and (3) smoking initiation (OR 1.6, 95% CI 1.1 to 2.6).

CONCLUSIONS

In developing accurate antismoking public health policies for older adolescents, the most vulnerable groups should be targeted. The results showed that most participants initiated smoking before 16 years of age. Therefore, further investigations should evaluate the predictors of smoking in younger ages.

Engaging parents of children with and without asthma in smoking-specific parenting: results from a 3-year Randomized Controlled Trial evaluation

The present study evaluated long-term effects of a home-based smoking prevention program targeting smoking-specific parenting in families with children with and without asthma. A total of 1398 non-smoking children (mean age 10.1) participated, of which 197 (14.1%) were diagnosed with asthma. Families were blinded to group assignment. The intervention group (n = 684) received booklets with assignments that actively encouraged parents to engage in smoking-specific parenting strategies. Control families (n = 714) received booklets containing basic information about youth smoking. Latent growth curve modeling was used to calculate intercepts and slopes to examine whether there was change in the different parenting aspects over the study period. Regression analyses were used to examine whether a possible change was different for intervention and control condition families with and without a child with asthma. For those smoking-specific parenting aspects that changed over time, families in the intervention and control condition increased similarly. Families with a child with asthma did not engage in parenting at higher levels due to the intervention program than parents of non-asthmatic children. This prevention program did not affect smoking-specific parenting in the Netherlands. Future prevention research could focus on other risk factors for smoking initiation among adolescents with asthma.

Adolescents' smoking experiences, family structure, parental smoking and socio-economic status in Ciudad Juárez, Mexico

BACKGROUND

Cigarette smoking is the leading cause of preventable death worldwide. Tobacco use and secondhand-tobacco smoke (SHS) exposure are classified as a pediatric disease. In Mexico, the prevalence of smoking has decreased among adults but paradoxically increased among adolescents, particularly among young females. This study was designed to determine the association between adolescents' smoking experiences (smoking behaviors and second hand smoke [SHS] exposure), family structure, parental smoking and socio-economic status (SES) in Ciudad Juárez, Mexico.

METHODS

This is a cross-sectional, population-based study. Data was collected from sixth-grade students (N = 506) attending school in Ciudad Juárez, Mexico. Descriptive analyses were conducted. The relationship between key outcome variables (adolescents smoking and SHS exposure) and independent variables (family structure, parental smoking, and SES level) were examined. Adjusted odds ratios were calculated. Multiple logistic regression analysis was performed while controlling for possible confounders (i.e. gender and age).

RESULTS

The overall prevalence of ever/lifetime smoking and SHS exposure at home was 29.6 and 41.1 %, respectively. Results of the logistic regression analysis show that being a member of a non-intact family [(OR = 2.20; 95 % CI = 1.21-3.90) and (OR = 2.45; 95 % CI = 1.19-4.10) respectively], having parents who smoke [(OR = 4.41; 95 % CI = 2.15-5.46) and (OR = 4.95; 95 % CI = 2.25-7.12) respectively], and living in low SES setting [(OR = 1.73; 95 % CI = 1.43-3.30) and (OR = 1.99; 95 % CI = 1.16-4.00) respectively] are significantly associated with ever smoking and SHS exposure at home among sixth grade students.

CONCLUSIONS

The findings of our study show that tobacco use and SHS exposure are strongly associated with adolescents living in low SES, non-intact households that have parents that smoke. To be effective, tobacco strategies specifically tailored for this particularly vulnerable group of adolescents would require a comprehensive, multi-faceted approach centered on prevention, cessation and protection.

Tobacco use among Norwegian adolescents: from cigarettes to snus

AIMS

To: (i) investigate the development of smoking and snus use among Norwegian adolescents, and (ii) describe the users in each group.

DESIGN

Two population-based surveys with identical procedures in 2002 (response rate 91.0%) and 2010 (response rate 84.3%).

SETTING

Norway.

PARTICIPANTS

A total of 6217 respondents, aged 16-17 years.

MEASUREMENTS

Data were collected on smoking and snus use, socio-demographic factors, school adjustment, social network, sport activities, alcohol and cannabis use and depression symptoms.

FINDINGS

Prevalence of daily smoking fell from 23.6% in 2002 to 6.8% in 2010 (P < 0.001), while the prevalence of daily snus use increased from 4.3 to 11.9% (P < 0.001). Dual daily use of cigarettes and snus remained at 1%. The relative proportion of non-daily smokers using snus increased steeply. Both snus users and smokers reported more adverse socio-economic backgrounds, less favourable school adjustment and higher levels of alcohol intoxication and cannabis use than non-users of tobacco. However, snus users were better adjusted to school and used cannabis less often than smokers.

CONCLUSIONS

Adolescent smoking prevalence has fallen dramatically in Norway, accompanied by a smaller increase in snus use. Young snus users in Norway have many of the same risk factors as smokers, but to a lesser degree.

Parenting practices and adolescent risk behavior: rules on smoking and drinking also predict cannabis use and early sexual debut

Previous research has provided considerable support for idea that increased parental support and control are strong determinants of lower prevalence levels of adolescent risk behavior. Much less is known on the association between specific parenting practices, such as concrete rules with respect to smoking and drinking and adolescent risk behavior. The present paper examined whether such concrete parental rules (1) have an effect on the targeted behaviors and (2) predict other, frequently co-occurring, risk behaviors (i.e., cannabis use and early sexual intercourse). These hypotheses were tested in a nationally representative sample of 12- to 16-year-old adolescents in the Netherlands. We found that both types of rules were associated with a lower prevalence of the targeted behaviors (i.e., smoking and drinking). In addition, independent of adolescent smoking and drinking behaviors, parental rules on smoking predicted a lower prevalence of cannabis use and early sexual intercourse, and parental rules on alcohol use also predicted a lower prevalence of early sexual intercourse. This study showed that concrete parental rule setting is more strongly related to lower levels of risk behaviors in adolescents compared to the more general parenting practices (i.e., support and control). Additionally, the effects of such rules do not only apply to the targeted behavior but extend to related behaviors as well. These findings are relevant to the public health domain and suggest that a single intervention program that addresses a limited number of concrete parenting practices, in combination with traditional support and control practices, may be effective in reducing risk behaviors in adolescence.

Best friend's and family members’ smoking habits and parental divorce during childhood are associated with smoking in adulthood

Aims

Smoking initiation during childhood or adolescence is strongly associated with friends’ smoking. Likewise, adverse living conditions increase the likelihood of future deviant behaviour. We examine whether smoking by a best friend and family members during school years as well as adverse childhood experiences are associated with smoking in adulthood.

Data and Design

We have analysed the responses of Finnish working-aged respondents in 1998 (N=25901) and 2003 (N=20773) to questions on the smoking status of friends and family members during school years as well as their answers on a six-item scale of childhood adversities. A case-control study design was used to compare current cigarette smokers (1998 and 2003) to non-smokers (1998 and 2003).

Results

If a best friend during school years was a smoker, the subject s odds ratio (OR) of being a smoker in adulthood was 4.43 among females and 3.91 among males compared to those with a non-smoking best friend in multivariate models adjusted for smoking by family members during school years and by six childhood adversities. These associations did not differ by age. Smoking in adulthood was associated with childhood adversities, most strongly with parental divorce or separation during the subjects’ school years.

Conclusion

Smoking by a best friend and parental divorce or separation during school years appears to be a strong factor of smoking in later life.
