Adverse childhood experiences and past 30-day cannabis use among middle and high school students: The protective influence of families and schools

The contribution of childhood maltreatment to the incidence of heavy cannabis use in Iran (IRNS-CCI): A multicenter, matched-pairs, nested, case-control study

BACKGROUND

Previous studies have shown the role of the interaction between the endocannabinoid system (ECS) and life's adversities in the formation of addiction, including alcohol abuse.

OBJECTIVE

Our objective was to identify childhood maltreatment (CM) patterns with the strongest impact on the probability of heavy cannabis use (THCCOOH concentrations ≥150 ng/mL) in Iran.

PARTICIPANTS AND SETTING

Using survivor sampling, 350 adult participants were selected, and they were then allocated to three categories based on an optimal algorithm: 1) Sexual abuse, 2) Physical abuse, and 3) Physical neglect.

METHODS

From 1 September 2019 to 1 May 2023, we implemented a multicenter, matched-pairs, nested, case-control study based on the wave 3-wave 6 data of a longitudinal, multicenter, cohort study. The cases and controls (n = 350 men) were defined according to the severity of CM. The THC potency was evaluated with the delta-9 carboxy tetrahydrocannabinol (THC-COOH) levels in urine using gas chromatography/mass spectrometry (GC/MS). We calculated the population attributable fractions (PAFs) to identify the patterns of maltreatment associated with the highest odds of high-potency cannabis use.

RESULTS

Accumulating CM, including sexual abuse, physical abuse, and physical neglect, carried more than three times the risk of heavy cannabis use (OR 3.4 95 % CI 2.9-4.1), and the combination of the three indicators of maltreatment and a high BMI (25-29.9) carried more than four times the risk of heavy cannabis use (OR 4.7 95 % CI 2.7-4.1) compared to the controls. We estimated that in the case of zero CM for each of the three indicators, over 20 % of new cases of heavy cannabis use can be prevented.

CONCLUSIONS

The findings show the significance of CM as a predicator of heavy cannabis use in adulthood and in the abstinence phase.

Multilevel Risk and Protective Factors for Frequent and Nonfrequent Past-30-Day Marijuana Use: Findings From a Representative Sample of High School Youth

OBJECTIVE

Research has identified many factors associated with past-30-day (P30D) marijuana use among youth but has not assessed factors that may differentiate youth who use frequently from youth who do not. We took a multilevel approach to identify and compare risk and protective factors associated with frequent and nonfrequent P30D marijuana use among high school students.

METHOD

Individual-level data were obtained from the 2019 Nevada Youth Risk Behavior Survey (completed by 4,980 high school youth from 99 schools); school-level data were obtained from the state's Department of Education. A multinomial, multilevel model was used to estimate the association between risk and protective factors at the individual and school levels and a three-level frequency of use outcome: no P30D use (0 times), nonfrequent P30D use (1-19 times), and frequent P30D use (≥20 times).

RESULTS

At the individual level, other P30D substance use, exposure to adverse childhood experiences (ACEs), perceived ease of access, and perceived risk were associated with both frequent and nonfrequent use, but the relationships were generally stronger for frequent use. P30D nonprescription drug use and school connectedness were associated with frequent use only. At the school level, number of students with individualized education programs, number of incidents involving possession of controlled substances, and school type were associated with frequent use only.

CONCLUSIONS

Individual and school-based interventions designed to address the factors uniquely or strongly associated with frequent marijuana use may prevent escalation from occasional use to more frequent use among high school youth.

Directional associations between cannabis use and depression from late adolescence to young adulthood: the role of adverse childhood experiences

BACKGROUND AND AIMS

Although the co-occurrence of cannabis and depression is well established, less is known about the temporal sequence of cannabis use and depression. The present study had three main aims: to test a symptom-driven pathway in which depression may drive increases in cannabis use, to test a substance-induced pathway in which cannabis use may drive increases in depression and to assess a shared vulnerability model assessing associations between individuals who have (and have not) experienced adverse childhood experiences (ACEs).

DESIGN

Data are from an ongoing, longitudinal, cohort study (n = 2234). Data were set up in an accelerated longitudinal design from age 17 to 24 years.

SETTING

Initial sample was recruited from Southern California, USA. The majority of participants still live in Southern California.

PARTICIPANTS

On average, participants were aged 18 years at wave 8, with more than half identifying as female (54.3%; n = 1350). Most participants identified as Hispanic (1127; 45.4%), followed by non-Hispanic white (510; 20.5%), Asian (503; 20.2%), multi-racial/other (284; 11.4%) and non-Hispanic black (60; 2.2%).

MEASUREMENTS

Primary outcomes were past-month days of cannabis use and depression symptoms [patient health questionnaire (PHQ)-8]. The Adverse Childhood Experiences scale was used as our main grouping measure.

FINDINGS

In the full sample, we showed that prior levels of depression symptoms were associated with a decrease in cannabis use [opposite to the proposed symptom driven model; B = -0.33 (-0.58, -0.09)]. Dynamic coupling parameters noted individuals who evidenced greater increases in cannabis use between two prior ages reported greater increases in depressive symptoms between subsequent ages [support for a substance-induced pathway; B = 0.53 (0.18, 0.89)]. Similar to the overall sample, for those who had not experienced ACEs, as cannabis use increased we saw a steady increase in depression [support for a substance induced pathway; B = 0.14 (0.04, 0.29)]. However, for those who experienced ACEs, as cannabis use increased we saw a consistent decrease in depression [opposite to the proposed substance-induced pathway; B = -0.18 (-0.28, -0.08)].

CONCLUSION

There is mixed support for both symptom-driven and substance-induced pathways between cannabis use and depression.

Comparison of adverse childhood experience analytic approaches and associations with emotional and behavioral problems: A nationwide study among Chinese middle school students

BACKGROUND

Adverse childhood experiences (ACEs) are demonstrated to be strongly associated with many health related problems, which have aroused extensive public attention. But the variety of analytic approaches of ACEs has limited researchers to differentiate those approaches across the outcomes.

METHODS

A total of 22,686 middle school students were surveyed, and their ACEs and health related behaviors were collected. Four different analytic approaches were used to compare the effects of ACEs on four outcomes (non-suicidal self-injury, suicidal ideation, depression and anxiety symptoms). Logistic regression models were applied to verify the associations of adversities and four outcomes. R² and the areas under the Receiver Operator Characteristic (ROC) curve were computed to compare the effects of four approaches.

RESULTS

It was suggested that four measures of ACEs were significantly associated with all the outcomes in both the unadjusted and adjusted models (Ps all <0.05). R² and areas under ROC curve showed that the contributions of four analytical approaches to different outcomes were diverse in this study. ACEs were more impactive to girls than to boys.

CONCLUSION

ACEs are profound influencing factors of emotional and behavioral problems among middle school students. The selection of analytic approaches of ACEs depends on the need of research, and our study contributes to the choice of suitable analytic methods for future research of ACEs.

Co-occurrence patterns of adverse childhood experiences and their associations with non-suicidal self-injury and suicidal behaviors and gender difference among middle school students: A three-city survey in China

BACKGROUND

Previous research has found increasing evidence of adverse childhood experiences (ACEs) leading to non-suicidal self-injury (NSSI) and suicidal behaviors. Most studies have focused on a certain type or timing of ACEs or the patterns of multiple types; however, few of them have examined the patterns of ACEs combined types and timing and the gender differences in the association between ACEs and self-harming behaviors.

METHODS

A cross-sectional survey was conducted in three Chinese cities from November 2020 to May 2021. We asked 16,853 middle school students to anonymously complete a questionnaire to provide the details of their own ACEs and NSSI or suicidal behaviors.

RESULTS

Latent class analysis identified four classes: high ACEs (10 %), high abuse/neglect (20.3 %), moderate ACEs (26.7 %) and low ACEs (43 %). Logistic regression models demonstrated that students in the high ACEs, high abuse/neglect and moderate ACEs subgroups were more likely to engage in NSSI and suicidal behaviors than students with low ACEs. Compared with boys, girls had a higher probability of engaging in NSSI and suicidal behaviors when exposed to the same level of ACEs.

CONCLUSION

Co-occurrence of ACEs is associated with high risk of NSSI and suicidal behaviors. Our findings recognized the most dangerous patterns and latent class membership, which supply the evidence for policy makers to adopt preventive measures to protect high-risk individuals. Strategies to relieve the impact of ACEs, especially on girls, need to be considered comprehensively.

LIMITATIONS

The study was limited by cross-sectional design, as causality could not be confirmed. In addition, because our survey was retrospective, potential recall bias can not be ignored.

Negative Life Events, Protective Factors, and Substance-Related Problems: A Study of Resilience in Adolescence

BACKGROUND

There is compelling evidence for an association between negative life events (NLE) and substance-related problems (SRP) during adolescence. The literature is, however, still limited with regards to protective factors for SRP among adolescents exposed to NLE.

METHODS

A large population-based survey including 9,611 Norwegian adolescents aged 16 to 19 years, comprised the dataset of this study. The main explanatory variable was NLE. The main outcome variable was SRP, assessed by the CRAFFT scale. Potential protective factors were measured with five subscales from the Resilience Scale for Adolescents (READ) questionnaire. The potential protective factors and sex were explored as moderators for the associations between NLE and SRP.

RESULTS

NLE were strongly associated with SRP. Four out of five potential protective factors (i.e., Goal Orientation, Self-confidence, Family Cohesion, and Social Support) showed evidence of a protective-stabilizing effect. Even if they had protective effect across all levels of exposure to NLE, these effects were even stronger for adolescents with high exposure. For Family Cohesion a protective-stabilizing effect was only evident for boys, while a direct protective effect was found for girls. Finally, Social Competence was the only factor that did not show any evidence of promoting resilience toward SRP.

CONCLUSIONS

NLE had a strong relation with SRP in this study. Protective factors buffered against SRP for all adolescents - but particularly so for adolescents who had high exposure to NLE. These findings highlight the need for preventive efforts to strengthen protective factors that may promote resilience among adolescents at risk for SRP.
