Multiple and Substitute Addictions Involving Prescription Drugs Misuse Among 12th Graders: Gateway Theory Revisited With Market Basket Analysis

Adverse Childhood Experience-Related Conditions and Substance Use in Adolescents: A Secondary Analysis of Cross-Sectional Survey Data

BACKGROUND

Adverse childhood experiences (ACEs) cluster within children. In addition to standardized ACE measures, there exist "ACE-related" measures that are either directly or indirectly related to the standardized ACE constructs. This study aimed to identify ACE-related latent classes of adolescents and describe past-month substance use in each class by sex and race/ethnicity.

METHODS

Data from the 2018 Indiana Youth Survey (N = 70,703), which is a repeated self-administered, cross-sectional survey, were used. Latent class analysis was conducted using ACE-related family (parent incarceration, insulting/yelling within family, inability to discuss personal problems) and school (hate being in school, feeling unsafe, inability to talk to teachers one-on-one) items. Dependent variable combined past 30-day use-frequency of 17 substances. Two-way analysis of variances examined ACE by sex and race/ethnicity interaction.

RESULTS

Four ACE-related classes emerged: "Family-Only" (11.2%), "School-Only" (16.5%), "Family-School" (8.0%), and "No-ACE" (64.3%). Substance use was highest in "Family-School" (mean = 0.67); lowest in "No-ACE" (mean = 0.21). Significant race/ethnicity (F = 27.06; p < .0001), ACE * sex interaction (F = 12.13; p < .0001) and ACE * race/ethnicity interaction (F = 4.57; p < .0001) effects emerged. Within each ACE-related class, substance use was lowest for Asians and highest for Hispanics.

CONCLUSIONS

Adverse childhood experience-related items cluster within children across school and family environments and clustering differs by race/ethnicity, but not by sex. Incorporating ACE-related items into school surveys enhances the ability to implement interventions that target relationships between ACEs and substance use.

Early-onset prescription drug misuse in Indiana youth

BACKGROUND

Based on 2018 national estimates, approximately 5-10% of youth between the ages of 12-17 report past year prescription drug misuse (PDM) in the United States. PDM among adolescents is associated with negative health outcomes and risk behaviors. The current study examined both the prevalence of PDM among diverse groups of adolescents and the association of alcohol and cigarette use with early PDM.

METHODS

Data came from the cross-sectional state-based 2018 Indiana Youth Survey of students from grades 6-12, ranging in age from 10 to 17 years (n = 80,926). Lifetime PDM, alcohol, and cigarettes were assessed by self-report, including ages at first use. A series of analyses were conducted separately for non-Hispanic Black, non-Hispanic White, and Hispanic students. We estimated the prevalence of PDM. Likelihood of PDM was estimated using the Kaplan-Meier survivor function. Cox proportional hazards regression models estimated age at first PDM from ages at first use of alcohol and cigarettes.

RESULTS

Three percent of non-Hispanic Black, 4% of non-Hispanic White, and 5% of Hispanic students reported PDM. Onset of smoking was associated with first PDM across adolescence for all groups. Onset of drinking was associated with first PDM among Hispanic students across adolescence. For Non-Hispanic Black and Non-Hispanic White students, likelihood of PDM was most pronounced during very early adolescence.

CONCLUSIONS

Onset of alcohol and cigarette use were associated with of PDM among Indiana youth, suggesting that interventions aimed at preventing early smoking and drinking may also reduce PDM among youth.

Sexual attraction and the nonmedical use of opioids and sedative drugs among Chinese adolescents

OBJECTIVE

The nonmedical use of prescription drugs (NMUPD) is attracting public attention. We aimed to explore the association between sexual attraction and NMUPD among Chinese adolescents.

METHOD

A school-based survey was conducted in seven Chinese provinces, and a multi-stage stratified cluster sampling method was used in this study. A total of 150,822 students from seven Chinese provinces completed the questionnaire; the response rate was 95.93%. All data were collected between November 2014 and January 2015.

RESULTS

Overall, 8.8%, 4.4%, and 2.2% of the students reported lifetime, past-year, and past-month NMUPD, respectively. Compared with heterosexual students (8.2%), sexual minority and unsure students were more likely to report lifetime NMUPD (14.4% and 10.0%, respectively; χ² = 244.34, P < 0.001). In addition, sexual minority and unsure students were more likely to admit past-year and past-month use of NMUPD. After adjusting for social demographics and lifestyle covariates, sexual minority and unsure students were at an increased risk of lifetime NMUPD (adjusted odds ratio [AOR] = 1.68, 95% confidence interval [CI] = 1.54-1.83 and AOR = 1.33, 95% CI = 1.26-1.41, respectively).

CONCLUSIONS

Our study suggested that sexual minority and unsure adolescents have a higher risk of NMUPD. Moreover, our study suggested that sexual minority and unsure students are more likely to both try and continue to use prescription drugs. Further studies focusing on the mechanism of substance abuse and appropriate interventions among sexual minority and unsure adolescents are warranted.

Double trouble: Exploring the association between waterpipe tobacco smoking and the nonmedical use of psychoactive prescription drugs among adolescents

BACKGROUND

In youth, both waterpipe tobacco smoking (WTS) and nonmedical use of prescription drugs (NMUPD) are globally growing concerns. This study assesses for the first time the lifetime and past-year associations between WTS and four classes of psychoactive prescription drugs.

METHODS

Cross-sectional data (2011) on 986 high school students attending public and private high schools in Beirut (Lebanon) was analyzed. Schools were selected using proportionate random cluster sampling from a comprehensive list of schools provided by the Ministry of Education.

RESULTS

Almost half (46%) had tried WTS compared to 25% who had ever tried cigarettes. Lifetime prevalence estimates of NMUPD were: pain relievers (8.2%), sedatives/tranquilizers (5.6%), stimulants (3.5%), antidepressants (2.5%), and sleeping pills (2.3%). WTS was associated with increased odds of sedatives/tranquilizer use (OR = 3.22, 95% CI: 1.25, 8.25), pain reliever use (OR = 4.31, 95% CI: 2.02, 9.17), and sleeping medication use (OR = 8.31, 95% CI: 2.37, 29.20), controlling for sex, age, school type, and other substance use. For cigarettes, the associations were consistently either weaker or non-existent, except with stimulant use (OR = 5.29, 95% CI: 1.55, 18.05).

CONCLUSIONS

While public health professionals have watched with caution the global prevalence of youth cigarette use-worldwide, an insidious alternative form of tobacco use has grown. Further research is needed to understand the unique risk factors and motives associated with WTS and how these relate to NMUPD in order to inform the development of effective intervention programs and policies that support youth positive health decisions.
