The role of spending money and drinking alcohol in adolescent smoking

Do sociodemographic risk profiles for adolescents engaging in weekly e-cigarette, cigarette, and dual product use differ?

BACKGROUND

E-cigarette use represents a contemporary mode of nicotine product use that may be changing the risk profile of participating adolescents. Understanding differences in sociodemographic characteristics of adolescents engaging in contemporary e-cigarette use and traditional cigarette use is important for effectively developing and targeting public health intervention programs. The objective of this study was to identify and compare sociodemographic risk profiles for exclusive e-cigarette use and dual-product use among a large sample of Canadian youth.

METHODS

A survey of 46,666 secondary school students in the 2021-22 wave of the COMPASS study measured frequency of past month e-cigarette and cigarette use as well as age, sex, gender, racial or ethnic background, spending money, relative family affluence, and having one's own bedroom. Rates of cigarette-only, e-cigarette-only, and dual product use were calculated, and separate classification trees were run using the CART algorithm to identify sociodemographic risk profiles for weekly dual-product use and weekly e-cigarette-only use.

RESULTS

Over 13% of adolescents used only e-cigarettes at least weekly, 3% engaged in weekly dual e-cigarette and cigarette use, and less than 0.5% used only cigarettes. Available spending money was a common predictor of dual-product and e-cigarette-only use. Gender diverse youth and youth with lower perceived family affluence were at higher risk for dual-product use, while white and multiethnic adolescents were at greater risk of e-cigarette-only use. Two high-risk profiles were identified for e-cigarette-only use and four high-risk profiles were identified for dual product use.

CONCLUSIONS

This study used a novel modelling approach (CART) to identify combinations of sociodemographic characteristics that profile high-risk groups for exclusive e-cigarette and dual-product use. Unique risk profiles were identified, suggesting that e-cigarettes are attracting new demographics of adolescents who have not previously been considered as high-risk for traditional cigarette use.

Adolescent income and binge drinking initiation: prospective evidence from the MyLife study

BACKGROUND AND AIMS

No previous studies have examined the prospective association between disposable income and binge-drinking initiation among adolescents. We aimed to examine whether there is such an association and, if so, whether it is robust to confounders, uniform across individual characteristics and linear versus non-linear.

DESIGN

Prospective study of adolescents from 32 middle schools, stratified according to geographic location, urban and rural locations and standard of living. Adolescents were assessed in 2017 (T1) and 1 year later (T2).

SETTING

Norway.

PARTICIPANTS

A nation-wide sample of 1845 adolescents (mean age 13.5 years, 44% boys) with no binge-drinking experience at T1.

MEASUREMENTS

Data were collected on binge drinking at T1 and T2. Data on disposable income and on a range of demographic, individual and family factors were collected at T1.

FINDINGS

Overall, 7.2% initiated binge drinking between T1 and T2. Logistic regression showed that the crude linear effect of disposable income on binge drinking initiation was substantial, and only slightly attenuated in the fully adjusted model including all putative confounders [odds ratio (OR) = 1.19, 95% confidence interval (CI) = 1.08, 1.31, P < 0.001]. However, interaction analyses showed disposable income to be negatively related to binge drinking initiation for adolescents who had experienced light drinking at T1 (OR = 0.66, 95% CI = 0.49, 0.89, P = 0.006) or who had seen their mothers intoxicated [OR = 0.62, 95% CI = 0.39, 0.99, P = 0.043).

CONCLUSION

Norwegian adolescents with higher disposable income have a greater risk of subsequent binge drinking initiation than those with lower disposable income. Each additional 100 NOK (≈ €10) of weekly income increased the risk of binge drinking initiation in the following year by approximately 20%.

Family and school social capitals in late childhood predict youthful drinking behaviors and problems

BACKGROUND

The present study aims to investigate the connection linking late childhood's family- and school- social capitals with subsequent alcohol drinking and problems.

METHODS

Data were obtained from the Alcohol-Related Experiences among Children survey in Taiwan. A total of 928 6th graders (age 11-12) were recruited from 17 elementary schools in an urban region in 2006 (response rate = 61.0%_wt); follow-ups were conducted at 8th grade (n = 783, follow-up rate = 82.6%_wt) and young adulthood (age 18-19; n = 645, follow-up rate = 68.0%_wt). Information concerning family social capital, alcohol drinking, and teacher-student relationship was collected by self-administered questionnaires; school social capitals were assessed via questionnaires and official statistics. Multilevel logistic regression analyses were used to evaluate relationship estimates.

RESULTS

At 8th grade, nearly one in ten reported having drunk alcohol on four or more occasions (i.e., occasional drinking) in the past year; and 14% reported past-month binge drinking in young adulthood. Effects of family social capital differed by developmental stage; parental involvement appeared prominent in reducing occasional drinking only in adolescence (adjusted Odds Ratio [aOR] = 0.54). School social capital (e.g., teacher-student ratio) was salient in shaping alcohol involvement in adolescence (occasional drinking: aOR = 0.80, 95% CI = 0.63-0.98) and young adulthood (binge drinking: aOR = 0.71, 95% CI = 0.67-0.86).

CONCLUSIONS

Our findings warrant future research on social capitals at family- and school- levels in late childhood, and inform preventive strategies targeting alcohol drinking and problems in young people.

Nonmedical opioid use and heroin use in a nationally representative sample of us high school seniors

BACKGROUND

Nonmedical use of opioids has become increasingly problematic in recent years with increases in overdoses, treatment admissions, and deaths. Use also appears to be contributing to heroin initiation, which has increased in recent years. Further research is needed to examine which adolescents are at highest risk for nonmedical use of opioids and heroin and to explore potential links between nonmedical opioid use and heroin use.

METHODS

Data were analyzed from a nationally representative sample of American high school seniors in the Monitoring the Future study (2009-2013, Weighted N=67,822). We examined associations between frequency and recency of nonmedical use of opioids and heroin. Sociodemographic correlates of use of each drug were also examined.

RESULTS

12.4% of students reported lifetime nonmedical opioid use and 1.2% reported lifetime heroin use. As frequency of lifetime nonmedical opioid use increased, so too did the odds for reporting heroin use, with over three-quarters (77.3%) of heroin users reporting lifetime nonmedical opioid use. Recent (30-day) nonmedical opioid use was a robust risk factor for heroin use and almost a quarter (23.2%) of students who reported using opioids ≥40 times reported lifetime heroin use. Black and Hispanic students were less likely to report nonmedical opioid or heroin use than white students, but they were more likely to report heroin use in absence of nonmedical opioid use.

DISCUSSION

Recent and frequent nonmedical opioid use are risk factors for heroin use among adolescents. Prevention needs to be targeted to those at highest risk.

Prevalence and correlates of hashish use in a national sample of high school seniors in the United States

BACKGROUND

Cannabis (marijuana) use and acceptance towards use are increasing in the US, and state-level policies are becoming more liberal. A wealth of research has been conducted to examine risk factors for use; however, studies rarely differentiate between different forms of marijuana.

OBJECTIVE

We sought to determine prevalence of use and delineate who is at risk for use of hashish, a more potent form of marijuana.

METHODS

We examined data from a nationally representative sample of high school seniors in the Monitoring the Future study (2007-2011; weighted n = 10 597). We determined how sociodemographic factors and reasons for marijuana use correlated with recent (12 month) hashish use.

RESULTS

Prevalence of recent hashish use was 6.5% and it was used by 18.3% of recent marijuana users. Hashish and other marijuana use tended to share many of the same correlates; however, associations were often stronger for hashish use. Females were consistently at low risk for use and users of other drugs were consistently at high risk for use. Black students tended to be at low risk for hashish use. Low risk of identifying as Hispanic or religious and high risk of higher personal income or going out more evenings per week for fun disappeared when controlling for other drug use. Using marijuana because the student felt he/she was "hooked" nearly doubled the odds for hashish use.

CONCLUSIONS

This was the first national study to examine prevalence and correlates of hashish use. These findings can inform prevention in a time of increasing popularity of marijuana use.

Powder cocaine and crack use in the United States: an examination of risk for arrest and socioeconomic disparities in use

BACKGROUND

In light of the current sentencing disparity (18:1) between crack and powder cocaine possession in the United States, we examined socioeconomic correlates of use of each, and relations between use and arrest, to determine who may be at highest risk for arrest and imprisonment.

METHODS

We conducted secondary data analyses on the National Survey on Drug Use and Health, 2009-2012. Data were analyzed for adults age ≥ 18 to determine associations between use and arrest. Socioeconomic correlates of lifetime and annual use of powder cocaine and of crack were delineated using multivariable logistic regression and correlates of frequency of recent use were examined using generalized negative binomial regression.

RESULTS

Crack users were at higher risk than powder cocaine users for reporting a lifetime arrest or multiple recent arrests. Racial minorities were at low risk for powder cocaine use and Hispanics were at low risk for crack use. Blacks were at increased risk for lifetime and recent crack use, but not when controlling for other socioeconomic variables. However, blacks who did use either powder cocaine or crack tended to use at higher frequencies. Higher education and higher family income were negatively associated with crack use although these factors were sometimes risk factors for powder cocaine use.

CONCLUSIONS

Crack users are at higher risk of arrest and tend to be of lower socioeconomic status compared to powder cocaine users. These findings can inform US Congress as they review bills (e.g., The Smarter Sentencing Act), which would help eliminate cocaine-related sentencing disparities.

Legal substance use and the development of a DSM-IV cannabis use disorder during adolescence: the TRAILS study

AIMS

To examine whether early onset of tobacco or alcohol use, and continued use of tobacco or alcohol in early adolescence, are related to a higher likelihood of developing a cannabis use disorder during adolescence.

DESIGN AND SETTING

Data were used from four consecutive assessment waves of the TRacking Adolescents' Individual Lives Survey (TRAILS), a general Dutch population study. TRAILS is an ongoing longitudinal study that will follow the same group of adolescents from the ages of 10 to 24 years.

PARTICIPANTS

The sample consisted of 1108 (58% female) adolescents (mean ages at the four assessment waves are 11.09, 13.56, 16.27 and 19.05 years, respectively)

MEASUREMENTS

Cannabis use disorders were assessed using the Composite International Diagnostic Interview 3.0 (CIDI). Adolescent tobacco and alcohol use were assessed using self-report questionnaires.

FINDINGS

Early-onset tobacco use [odds ratio (OR) = 1.82, confidence interval (CI) = 1.05-3.14, P < 0.05], but not early-onset alcohol use (OR = 1.33, CI = 0.84-2.12, P > 0.05), was associated with a higher likelihood of developing a cannabis use disorder. Similarly, adolescents who reported continued use of tobacco (OR = 2.47, CI = 1.02-5.98, P < 0.05), but not continued use of alcohol (OR = 1.71, CI = 0.87-3.38, P > 0.05), were more likely to develop a cannabis use disorder.

CONCLUSIONS

Early-onset and continued tobacco use appear to predict the development of a cannabis use disorder in adolescence, whereas early onset and continued alcohol use do not.

Demographic and socioeconomic correlates of powder cocaine and crack use among high school seniors in the United States

OBJECTIVES

Rates of powder cocaine and crack use have fluctuated among adolescents over recent decades. Little attention has been paid to recent trends, particularly regarding differences between users of powder cocaine and crack-two forms of the substance that are commonly reported together as "cocaine" use, despite having different effects and rates of adverse outcomes.

METHODS

We examined data from nationally representative samples of high school seniors who participated in the Monitoring the Future study during years 2005-2011 (weighted N = 65 717).

RESULTS

Many demographic and socioeconomic variables were similarly correlated with lifetime use of powder cocaine and crack. Income of >$50/week from job increased the odds for use, and income of >$50/week from sources other than a job more than doubled the odds for use. High religiosity, high parent education, identifying as black, and residing with one or two parents reduced odds for use. Hispanic students were at higher odds for use of crack and females were at lower odds for using powder cocaine. Among cocaine users, residing with one or two parents lowered odds for using both forms, and more religious students and Hispanics were at higher odds for crack-only use.

CONCLUSIONS

Those interested in preventing initiation and adverse consequences of cocaine use should take into account the overlapping, yet different risk profiles of powder cocaine and crack users when developing programming. This is particularly important when considering differences in legal consequences for these pharmacologically similar forms of cocaine.

Disposable income with tobacco smoking among young adolescents: a multilevel analysis

PURPOSE

Prior studies examining the connection between disposable income and adolescent smoking often yielded mixed results, partly due to the lack of consideration for contextual variables. In the present study, we sought to broaden understanding of disposable income on adolescent smoking behaviors via both absolute and relative perspectives in the school context.

METHODS

We obtained data from the 2010 Global Youth Tobacco Survey (GYTS) in Taiwan. Information concerning sociodemographics, disposable income, smoking history, and contextual smoking exposure (e.g., school) were assessed via self-report. Recent-onset smokers were defined as those who had their first cigarette within two years of the survey. Complex survey and multilevel analyses were carried out to estimate association.

RESULTS

Adolescents with higher monthly disposable income were 2∼5 times more likely to start smoking and become regular smokers. Having the least disposable income in a class appeared linked with increased risk of tobacco initiation by 40% (95% confidence interval [CI]: 2%-91%). Pupils' odds to start smoking were lowered to .70 when the majority of schoolmates had low disposable income (95% CI: .51-.99).

CONCLUSIONS

Adolescent risk of smoking initiation may be differentially affected by individual- and contextual-level absolute and relative disposable income. Future research is needed to delineate possible mechanisms underlying unfavorable health behaviors associated with disposable incomes in early adolescence.

Patients' Preferences for Generic and Branded Over-the-Counter Medicines: An Adaptive Conjoint Analysis Approach

BACKGROUND

: Despite increased use of generic medicines, little is known about either the attitudes of patients towards them or the decision-making process surrounding them. Young adults use over-the-counter (OTC) analgesics relatively often.

OBJECTIVE

: To assess the preferences of patients for generic and branded OTC pain medicines, to identify clusters with different preference structures, and to estimate the price elasticity of a generic alternative among university students.

METHODS

: Finnish university students (n = 256; students in courses at the Helsinki School of Economics) responded to an adaptive conjoint analysis (ACA) questionnaire on the choice between branded and generic OTC ibuprofen products. Product attributes of price, brand, onset time of effect, place of purchase and source of information were included in the questionnaire on the basis of the literature, a focus group and a previous pilot study. Several socioeconomic and health behavior descriptors were employed. Individual-level utility functions were estimated, preference clusters were identified, and the price elasticity of the generic medicine was assessed.

RESULTS

: Five clusters with characteristic individual-level preferences and price elasticity but few differences in socioeconomic background were detected. Approximately half of the respondents were strongly price sensitive while the others had other preferences such as brand or an opportunity to buy the medicine at a pharmacy or to have a physician or a pharmacist as an information source.

CONCLUSION

: The study provided new information on the concomitant effects of brand, price and other essential product attributes on the choice by patients between branded and generic medicines.

How does youth cigarette use respond to weak economic periods? Implications for the current economic crisis

This paper examines whether youth cigarette use increases during weak economic periods (as do youth alcohol and drug use). The data come from the 1997 National Longitudinal Survey of Youth. With repeated measures over the 1997-2006 period, for almost 9,000 individuals, the samples include 30,000+ teenagers (15-19 years) and 30,000+ young adults (20-24 years). Logit models with state and year controls are estimated. The results indicate that teenagers and young adults increase cigarette use when the economy is weaker, implying that the current financial crisis has likely increased youth cigarette use relative to what it would have otherwise been.

Why to smoke? Why not to smoke? Major reasons for children's decisions on whether or not to smoke

This study, aimed at the primary prevention of smoking behaviour in children and adolescents, attempts to find the main factors that distinguish smokers and non-smokers in the period of their first experimentation with cigarettes. There are only a few studies dealing with investigations into current motivations of teenagers as to whether or not to smoke. The programme entitled "Normal is not to smoke", using evaluation questionnaires given to children in the 3rd and 5th classes, also contains--among many other things--specifics on reasons children have for making the decision whether to become a smoker or non-smoker. The results are reported in this paper.

METHODOLOGY

Responses concerning potential inclination to smoking that were collected from children on the basis of questionnaires were categorized into the following groups: image, the influence of a role model, the effects of smoking, curiosity. Reasons for non-smoking were categorized into the following groups: health, aesthetic, economic, restrictive, other aspects. Children were also asked to describe smokers by using three pairs of opposite characteristics: education, success, wealth. The frequencies of answers were analysed for the whole set, for boys and girls and for children with different smoking behaviour; the differences were evaluated using the statistical programme EPI INFO, version 6.

RESULTS

A total of 1153 children in the 3rd class and 799 children in the 5th class completed the questionnaire. Motivations for smoking were given by nearly 17% of children in the 3rd class and by nearly 27% of the same cohort in the 5th class. Aspects such as image (41.9% vs. 46.2%) were mentioned most frequently, by boys more frequently than by girls (OR 1.77; 95% CI 0.93-3.36; p = 0.06), by children from smokers' families more frequently than by children from non-smokers' families (OR 1.33; 95% CI 0.69-2.57; p = 0.3) and more frequently by children with repeated attempts to smoke (OR 3.93; 95% CI 2.32-6.65) or children who had only had a single smoking attempt (OR 3.18; 95% CI 1.52-6.75). Also the role of models (parents, relatives, friends) was often mentioned (12.9% in the 3rd class and 10.2% in the 5th class). Potential beneficial effects of smoking were expressed by 13% of children in the 3rd class and by 55% of children in the 5th class (p < 0.0001). About 40% of children considered smoking as effective coping with stress and about 20% of them declared smoking for mood improvement. Beneficial effects of smoking significantly more often described children with repeated smoking attempts (OR 2.91; 95% CI 1.73-4.89; p < 0.001). Children often linked smoking to the less educated and less successful social groups but also to the rich. In both investigations, health aspects were the most common reasons for choosing not to smoke (69.2% vs. 73.3%), being more frequently presented by girls and non-smokers. A significant shift in the negative aesthetic perception of smoking (14.1% in the 3rd class vs. 40.2% in the 5th class) and economic disadvantages of smoking (3.9% vs. 24.8%) was observed in the given period of time. Restrictive reasons were given only rarely by pupils in the 3rd class (0.7%), unlike pupils in the 5th class who feared the reaction of their parents (24.8%).

CONCLUSION

Our study provides an overview of current motivations in children aged 9 and 11 years that are crucial for their future smoking/nonsmoking behaviour. The results of the study are important for developing a strategy for the primary prevention of smoking in school programmes and for introducing a general social approach to address the problem of the decreasing age of smoking initiation.
