Childhood cigarette and alcohol use: Negative links with adjustment

Risk and protective factors for substance use and media addictive behaviors in adolescents during the COVID-19 pandemic

OBJECTIVE

This study examined the long-term effects of the COVID-19 pandemic on adolescents' substance use, digital media use, and symptoms of internet, gaming, and social media addiction.

METHOD

A nationally representative longitudinal cohort of 1665 Israeli teens and preteens, aged 9-16, completed questionnaires assessing substance use prevalence, daily screen time, symptoms of media addiction, and potential risk and protective factors. Data were collected before the pandemic (October 2019), after the second wave lockdown (November 2020), and after the fifth wave (April 2022) in Israel.

RESULTS

The analysis documented significant increases in substance use, daily screen time, and social media addiction indices over time. Gratitude, life satisfaction, positive emotions, future orientation, grit, and secure attachment emerged as significant protective factors. Sensation-seeking, negative emotions, and mental health symptoms were identified as risk factors.

CONCLUSIONS

These findings highlight the importance of educational and public mental health services in addressing the pandemic's long-term impact on the mental health and addictive behaviors of adolescents. They also emphasize the significance of enhancing protective factors and reducing risk factors to effectively mitigate substance and digital media abuse among adolescents.

Police stops and adolescent sleep problems: findings from the UK millennium cohort study

Youth-police contact has been shown to undermine various facets of adolescent health and well-being. The present study extends this body of research by assessing the association between police stops and sleep problems among a large, representative sample of adolescent in the UK (N = 11,200). The findings reveal youth-police contact was associated with all facets of sleep examined, including shorter sleep durations, longer sleep latency, and frequent mid-sleep awakenings. Ancillary analyses of a subsample of youth using daily time-use diaries (TUDs) largely corroborate these findings in the case of short sleep durations. Additionally, the odds of experiencing multiple sleep problems were greatest among youth who were arrested/taken into custody, but significant nonetheless even in the absence of arrest. These findings indicate the need for strategies and interventions among both public health practitioners and law enforcement that mitigate the adverse repercussions of police stops for adolescent sleep health.

Electronic cigarette use in adolescence is associated with later cannabis use

BACKGROUND

Research is needed to determine whether e-cigarette use during adolescence is associated with higher odds of subsequent cannabis use, net of tobacco cigarette use and childhood confounders.

METHODS

Multivariable logistic regressions predicting using cannabis by age 17 based upon prospective, intergenerational data from 10,251 youth in a nationally representative UK birth cohort followed from infancy who had not used cannabis by age 14. The focal predictor is e-cigarette use by age 14 in the context of the potential confounder tobacco cigarette use. Regressions include sociodemographic background and risk factors assessed at age 11 (e.g., alcohol initiation, problem behaviors, parental and peer smoking) and during early childhood (e.g., maternal smoking during pregnancy, parental substance use).

RESULTS

Youth use of e-cigarettes by age 14 was associated with 2.8 times higher odds of subsequent cannabis use by age 17 [OR 2.75; 95% CI 1.82,4.15], net of tobacco cigarette smoking and childhood confounders. Similarly, use of e-cigarettes by age 14 was associated with 2.5 times higher odds [OR 2.46; 95% CI 1.48,4.08] of frequent cannabis use at age 17 (>10 times in prior year). If youth used both e-cigarettes and tobacco cigarettes by age 14, the probabilities of cannabis initiation were 75% and of frequent use was 25% by age 17, compared to probabilities of 23% and 6%, respectively, among youth who had used neither product.

CONCLUSIONS

Findings add to accumulating evidence that adolescent e-cigarette use is associated with higher odds of later cannabis initiation and frequent use, independent of tobacco cigarette use.

Adolescent electronic cigarette use and tobacco smoking in the Millennium Cohort Study

AIMS

To evaluate the catalyst, diversion and common liability hypotheses by examining associations between e-cigarette use and tobacco cigarette smoking at modal ages 14 and 17 years, controlling for adolescent and infancy risk factors.

DESIGN

Intergenerational, prospective cohort data from the Millennium Cohort Study (MCS). Nationally representative sample of infants born September 2000 to January, 2002.

SETTING

United Kingdom.

PARTICIPANTS

Parent and child data from 10 625 youth assessed in infancy and modal ages 11, 14 and 17 years.

MEASUREMENTS

Age 14 and 17 e-cigarette and combustible cigarette use (recency, frequency). Potential confounders were age 11 risk factors (e.g. alcohol use, externalizing behaviors, parental tobacco use, permissiveness), infancy risk factors (e.g. maternal smoking during pregnancy, smoke exposure in infancy) and demographic characteristics.

FINDINGS

Among youth who had not smoked tobacco by age 14 (n = 9046), logistic regressions estimated that teenagers who used e-cigarettes by age 14 compared with non-e-cigarette users, had more than five times higher odds of initiating tobacco smoking by age 17 [odds ratio (OR) = 5.25, 95% confidence interval (CI) = 3.28-8.38] and nearly triple the odds of being a frequent tobacco smoker at age 17 (OR = 2.91, 95% CI = 1.56-5.41), net of risk factors and demographics. Among youth who had not used e-cigarettes by age 14 (n = 9078), teenagers who had smoked tobacco cigarettes by age 14 had three times higher odds of initiating e-cigarettes by age 17 (OR = 2.98, 95% CI = 1.74-5.09) compared with non-tobacco smokers and nearly three times higher odds of frequently using e-cigarettes at age 17 (OR = 2.90, 95% CI = 1.21-6.95), net of confounders. Similar links between e-cigarette and tobacco cigarette use were observed in regressions following coarsened exact matching.

CONCLUSIONS

E-cigarette use by age 14 is associated with increased odds of tobacco cigarette initiation and frequent smoking at age 17 among British youth. Similarly, tobacco smoking at age 14 is associated with increased odds of both e-cigarette initiation and frequent use at age 17.

Testing risk and protective factor assumptions in the Icelandic model of adolescent substance use prevention

Iceland has witnessed a dramatic decline in adolescent substance use that may be partly the result of efforts related to the Icelandic prevention model (IPM). We sought to test risk and protective factor assumptions of the IPM using a prospective cohort study with 12 months separating baseline from follow-up. Participants were students in grades 8 and 9 in the national Icelandic school system enrolled in the spring of 2018 and 2019 (N=2165). Participants self-reported their experiences of cigarette smoking, alcohol consumption, and cannabis use and seven risk and protective factors. Analyses were conducted with generalized linear modeling with extension to general estimating equations with correlated outcomes data. Both individual main-effects models and collective models including all main-effects were tested. Out of 28 individual main-effects models, 23 produced findings consistent with study premises (P<0.05). Multiple main-effects models largely sustained the findings of the individual main-effects models. Findings support the assumption that the risk and protective factors commonly emphasized in the IPM are associated with the four different substance use outcomes in the hypothesized direction. Communities that plan to implement the IPM among adolescents might consider these factors in their work.

Parents Allowing Drinking Is Associated With Adolescents' Heavy Alcohol Use

BACKGROUND

Using intergenerational prospective data from the Millennium Cohort Study (MCS), we examine whether parents allowing 14-year-olds to drink alcohol is associated with greater likelihood of early adolescents' heavy episodic drinking (i.e., lifetime, rapid escalation from first drink, and frequent past year), beyond shared risk factors for parental alcohol permissiveness and adolescent alcohol use.

METHODS

The MCS is a unique, contemporary, nationally representative study with mother, father, and child data from infancy through age 14 years (n = 11,485 children and their parents). In a series of multivariate logistic regressions, we estimated whether teenagers whose parents allowed them to drink alcohol (16% of parents said "yes") faced an elevated likelihood of heavy alcohol use at age 14, controlling for a large host of likely child and parent confounders measured when children were age 11. To further assess plausible intergenerational associations of parental alcohol permissiveness and offspring heavy alcohol use, coarsened exact matching (CEM) was used to match 14-year-olds whose parents allowed them to drink alcohol with teens whose parents did not allow them to drink on these childhood antecedent variables.

RESULTS

Adolescents whose parents allowed them to drink had higher odds of heavy drinking (odds ratio [OR] = 2.40; 95% confidence interval [CI] = 1.96 to 2.94), rapidly escalating from initiation to heavy drinking (OR = 1.94; CI = 1.52 to 2.49), and frequent heavy drinking (OR = 2.32; 1.73 to 3.09), beyond child and parent confounders and using CEM methods.

CONCLUSIONS

Adolescents who were allowed to drink were more likely to have transitioned quickly from their first drink to consuming 5 or more drinks at 1 time and to drinking heavily 3 or more times in the past year. Given well-documented harms of adolescent heavy drinking, these results do not support the idea that parents allowing children to drink alcohol inoculates them against alcohol misuse.

Alcohol and tobacco experimentation among adolescents of the Midwest Region/Brazil

This study aims to investigate the prevalence of alcohol and tobacco experimentation among adolescents of the Brazilian Midwest its association with sociodemographic factors. This is a cross-sectional study, with data from the National School Health Survey - PeNSE, carried out in 2015. The sample consisted of ninth-graders. The dependent variable was alcohol and tobacco experimentation at some point in life. A Poisson regression model was performed to identify the associated variables. The weighted estimated prevalence of alcohol and tobacco experimentation was 57.17% (95% CI: 56.20-58.14) and 22.38% (95% CI: 21.56-23.20), respectively. The prevalence of alcohol experimentation among females was higher than in males. However, regarding tobacco, males had a higher prevalence than females. Alcohol and tobacco experimentation was statistically significant with age. Public schools' administrative dependency showed a 23.99% higher prevalence than private schools concerning tobacco experimentation. We concluded that alcohol and tobacco experimentation was high among school adolescents and was shown to be associated with sociodemographic factors .

Very early drinking: Event history models predicting alcohol use initiation from age 4 to 11 years

While it is not normative to initiate alcohol use prior to adolescence, substantial numbers of children do so. However, relatively little is known about the prevalence or predictors of alcohol initiation in childhood, compared to extensive research on adolescent initiation and alcohol use. The present study examines patterns and predictors of very early drinking initiation in childhood, focusing on child behavioral undercontrol and parent alcohol and drug use as time-varying risk factors across childhood, independent of sociodemographic background variables. Event history analyses model and predict the age of alcohol initiation across ages 4 to 11 in the ongoing Millennium Cohort Study. Methodological strengths include the prospective design initiated in infancy (prior to any alcohol consumption), multiple reporters, and large representative sample of children and parents (n = 11,355). Key predictors are child behavioral undercontrol and parent alcohol and drug use assessed across childhood. Weighted results show that <2% of children had their first drink of alcohol prior to their 8th birthday, rising to 13% by age 10-11 years. Odds of initiation are higher when parents rated children as behaviorally undercontrolled and when at least one parent in the household reported drinking alcohol and/or using illegal drugs, independent of sociodemographic group differences. Thus, an important minority initiated drinking during childhood, and there are key risk factors for early drinking. Increased focus on the epidemiology, etiology, and prevention of childhood drinking is needed.

Risk factors associated with early smoking onset in two large birth cohorts

We use prospective data from the ongoing British Cohort Study (BCS) and Millennium Cohort Study (MCS) to: 1) document changes in the prevalence of childhood smoking onset; 2) assess whether broad historic shifts in key risk factors, such as maternal education, parental smoking, and peer childhood smoking, explain observed cohort changes in childhood smoking; and 3) evaluate whether inequalities in onset have narrowed or widened during this period. The children in these two studies were born 31 years apart (i.e., BCS in 1970; MCS in 2001), and were followed from infancy through early adolescence (n = 23,506 children). Our outcome variable is child self-reports of smoking (ages 10, 11). Early life risk factors were assessed via parent reports in infancy and age 5. Findings reveal that the odds of childhood smoking were over 12 times greater among children born in 1970 versus 2001. The decline in childhood smoking by cohort was partly explained by increases in maternal education, decreases in mothers' and fathers' smoking, and declines in the number of children whose friends smoked. Results also show that childhood smoking is now more linked to early life disadvantages, as MCS children were especially likely to smoke if their mother had low education or used cigarettes, or if the child had a friend who smoked. Although the prevalence of child and adult smoking has dropped dramatically in the past three decades, policy efforts should focus on the increased social inequality resulting from the concentration of early life cigarette use among disadvantaged children.

Parents Who Allow Early Adolescents to Drink

PURPOSE

Previous research on community samples reveals that a sizeable minority of parents allow their early adolescent children to drink alcohol. The present study documents in a national longitudinal study the prevalence of parents allowing 14-year-olds to drink and examines variation by sociodemographic background and parent alcohol use.

METHODS

Children and parents (n = 10,210 families) participating in the ongoing Millennium Cohort Study provided self-report data from when the child was an infant to age 14 years.

RESULTS

About 17% of parents allowed their early adolescents to drink. Employed, more educated, and non-abstaining parents of white children were more likely to permit early adolescent drinking. Permitting alcohol use did not vary by child gender, teenage or single parenthood, or variation in parental drinking level.

CONCLUSIONS

Socioeconomically advantaged, non-abstaining parents evidence a more permissive attitude about early drinking, which is a risk factor for early initiation, heavier use, and other problem behaviors.
