Use of psychoactive substances by adolescents: current panorama

Psychotic symptoms and its associated factors relating to psychoactive substance use among the youth population in Northwest Ethiopia

Background

Substance use is associated with high rates of psychiatric symptoms including psychotic symptoms. Despite the severity of the problem, there are intervention gaps in Ethiopia. To combat this, relevant evidence is required to raise the awareness of service providers. This study aimed to assess the prevalence of psychotic symptoms and its associated factors among the youth population who uses psychoactive substances in the Central Gondar Zone, Northwest Ethiopia.

Methods

A community-based cross-sectional study was conducted among the youth population in the Central Gondar zone, Northwest Ethiopia, from 01 January to 30 March 2021. A multistage sampling technique was used to recruit the study participants. All data were collected using questionnaires assessing socio-demographic; family-related variables; Depression, Anxiety, and Stress Scale; Multidimensional Scale Perceived Social Support (MSPSS), and Self-Reporting Questionnaire (SRQ-24). The data were analyzed using the STATA 14 statistical program.

Results

A total of 372 young people who used psychoactive substances (79.57%, 53.49%, 34.14%, and 16.13% were consuming alcohol, Khat, tobacco/cigarette products, and other substances such as shisha, inhalants, and drugs, respectively) were included in the study. The prevalence of psychotic symptoms was 24.2% with a 95% CI: 20.1, 28.8. Being married [AOR = 1.87 95% CI: 1.06, 3.48], recent loss of loved ones [AOR = 1.97 95% CI: 1.10, 3.18], low perceived social support [AOR = 1.61 95% CI: 1.11, 3.02], and severe psychological distress [AOR = 3.23 95% CI; 1.64, 6.54] were the factors associated with psychotic symptoms among young people with psychoactive substances use at a p-value of < 0.05.

Conclusion

Psychotic symptoms related to psychoactive substances among the youth population in Northwest Ethiopia were high. Thus, it is better to give a special attention to the youth population with low social support and existing psychological distress concurrent with psychoactive substance use.

Do varsity college athletes have a greater likelihood of risky alcohol and cannabis use than non-athletes? Results from a National Survey in Brazil

OBJECTIVE

We examined the prevalence of risky alcohol and cannabis use among Brazilian varsity college athletes and whether this group had a greater likelihood of risky use than non-athletes.

METHODS

In 2009, Brazilian college students (n=12,711) were recruited for a national stratified random survey. Their sociodemographic characteristics, mental health, substance use, and participation in varsity sports were assessed. Binary logistic regression models were used to examine the association between varsity athlete status and moderate to high-risk alcohol and cannabis use.

RESULTS

Among varsity athletes, 67.6 and 10.7% reported risky alcohol and cannabis use, respectively. Varsity athletes had greater odds of risky alcohol consumption than non-athletes (aOR = 2.02, 95%CI 1.08-3.78). Varsity athletes also had greater odds of risky cannabis use than non-athletes in unadjusted analyses (OR = 2.57, 95%CI 1.05-6.28), although this relationship was attenuated after covariate adjustment.

CONCLUSIONS

Among college students in Brazil, varsity athletes had a higher prevalence of risky alcohol and cannabis use than non-athletes. The rates were considerably higher than those observed among samples of U.S. college athletes. Future research should examine the use of these substances among varsity college athletes in other middle-income countries since these findings will likely guide prevention and treatment efforts.

Hospitalization due to mental and behavioral disorders caused by use of alcohol and psychoactive substances among older adults and elderly people in Brazil: a cross-sectional study

BACKGROUND

It has been estimated that 17% of individuals aged 50 years or older suffer from addiction to legal or illegal drugs. Use of alcohol and psychoactive substances has been correlated with several diseases, e.g. psychiatric conditions and cardiovascular and sexual dysfunctions.

OBJECTIVE

To discuss the Brazilian profile of mental and behavioral disorders caused by use of alcohol and psychoactive substances among older adults and elderly people, over the period from 2008 to 2019.

DESIGN AND SETTING

Cross-sectional study conducted among Brazilians aged 50 years or older.

METHODS

Hospitalization due to mental and behavioral disorders caused by use of alcohol and psychoactive substances was assessed through data obtained from the National Health System Department of Informatics (Departamento de Informática do Sistema Único de Saúde, DATASUS).

RESULTS

Decreasing and steady trends of hospitalization due to mental and behavioral disorders caused by use of alcohol among both men and women at all ages were observed. Similar trends were reported for all age ranges among men and women aged 60 years and older. In contrast, a slight increase was seen among women aged 50 to 59 years.

CONCLUSION

These data are crucial for qualifying mental healthcare for older adults and elderly people and for planning mental health services.

Depression, anxiety, and drug usage history indicators among institutionalized juvenile offenders of Brasilia

INTRODUCTION

One of the most serious socio-educational measures for children and adolescents in conflict with the law in Brazil is their internment. This measure may represent an additional source of stress to this population and present significant impacts in the mental health context. This study aims to describe anxiety levels, depression, and addictive consumption, as well as to estimate the causalities and interactions of these variables.

METHODS

Herein, we report a study in which 175 male juveniles from youth detention institutions of the Federal District voluntarily completed the Beck Depression Inventory (BDI), the Beck Anxiety Inventory (BAI), and a short self-rating questionnaire asking whether and how often they had experienced cannabis, alcohol, and other "hard" psychotropic drugs (e.g., crack, cocaine, amphetamine) 1 year prior to institutionalization.

RESULTS

Of the total participants, 28.00% showed moderate to severe depression scores and 34.28% showed moderate to severe anxiety scores. In addition, the vast majority of participants also reported some antecedent drug abuse, including cannabis, alcohol, and other "hard drugs." The BDI scores moderately correlated with BAI, but none of these parameters considerably correlated with the antecedent drug abuse.

CONCLUSIONS

The data indicate potentially concerning levels of emotional distress in these institutionalized juveniles which seem to be independent of addictive behaviors. These data deserve attention and further investigation. Thus, a need for preventative mental health for the general population and socio-educational intervention aimed at interned youth which can decrease levels of emotional stress is emphasized.

A cluster randomized controlled trial evaluating the effectiveness of the school-based drug prevention program #Tamojunto2.0

AIMS

The study aimed to evaluate the effectiveness of the government school-based program #Tamojunto2.0, the third Brazilian version of the European drug prevention program, Unplugged, in preventing the use of alcohol and other drugs.

DESIGN

A parallel, two-arm cluster randomized controlled trial was conducted in 205 classes in 73 public schools (37 intervention and 36 control) with a baseline assessment and follow-up after 9 months.

SETTING

Schools in the cities of São Paulo, Fortaleza and Eusebio in Brazil.

PARTICIPANTS

A total of 5208 students in the 8th grade with a mean age of 13.2 years (standard deviation = 0.8 years) and an equal gender ratio.

INTERVENTION

In 2019, the intervention group attended 12 classes of the program #Tamojunto2.0, under the supervision of a team from the Ministry of Health. The control group did not receive any intervention to prevent alcohol and drug use.

MEASUREMENTS

The primary outcome measured was prevalence of binge drinking (five or more doses of alcohol in an occasion) within the past month. Secondary outcomes were prevalence of initiation and use of alcohol, tobacco, inhalants, marijuana and cocaine within the past month.

FINDINGS

A statistically significant difference was not found in the prevalence of binge drinking within the past month between intervention and control groups [odds ratio (OR) = 0.934; 95% confidence interval (CI) = 0.761-1.146]. However, students who were exposed to the program were less likely to initiate alcohol use than those in the control group (OR = 0.782; 95% CI = 0.636-0.961). The Bayes factor for reduction in binge drinking was 0.01, providing evidence in favor of the null hypothesis for this variable.

CONCLUSIONS

The drug prevention program #Tamojunto 2.0 reduced alcohol initiation, but appeared not to reduce past-month binge drinking among 8th grade students in Brazil.

Assessment of use of psychoactive and other non-prescription drugs among students of selected tertiary institutions in Ekiti State South West Nigeria - A baseline study

Background

Substance abuse is causing increasing threats to the stability of young minds, from teenage to the older youths and is an issue of public health concern in Nigeria. This study was carried out to determine the prevalence of drug abuse among students of tertiary institutions in Ekiti State.

Methodology

A comparative cross-sectional survey was carried out among students in tertiary institutions in Ekiti state with participants selected from Year 1 to Year 4. Data collection tool was the WHO questionnaire (STASSIS). Data was analysed to obtain descriptive and inferential data, Kruskal-Wallis test and chi square were used for analysis of variance and test of association.

Result

The majority of the students reported low use of all the drugs (64–90.1%) though moderate to high use were reported for: alcohol 35.1%, marijuana 15.7%, heroine 15.3%, tobacco 13.8% and cocaine 10.2%. There was a significant association between student's moderate to high use and university type. Students in private universities reported more use, especially heroine. Difference in substance use across the four years surveyed was significant with final year students (400 level) showing highest use.

Conclusion

Tertiary students in Ekiti state are low users of psychoactive substances with a prevalence of 60–91%. Moderate to high prevalence of 10–31% was reported with alcohol as the substance with highest usage. Substance use varied significantly with university type with highest prevalence in the private institution and students at different academic levels with final year students being the highest users.

Attitudes are associated with the drug use profiles of middle school adolescents: A latent class analysis

The association between positive and negative attitudes and drug use profiles is examined. Participants were public middle school students (N = 5213; 49.9% girls; M age= 13.2 years) in three Brazilian cities. Analysis was performed using baseline surveys of a randomized controlled trial of the #Tamojunto2.0 drug use prevention program. We validated the attitudes construct via a confirmatory factor analysis and performed a simultaneous multinomial regression with a latent class analysis. Three latent classes were identified: abstainers/low users (ABS) (63.4%), alcohol users/binge drinkers (ALC) (29.5%), and polydrug users (POL) (7.1%). An association gradient was found between attitudes and latent classes. Using ABS as reference, a direct association was identified between positive attitudes and ALC and POL. An inverse association was found between negative attitudes and POL only. Girls and older students were more likely to be ALC and POL. These findings, from a large probabilistic sample, provide guidance that drug use prevention programs should focus on deconstructing positive attitudes -mainly- and broadening negative attitudes, and should adapt their thematic content by considering the differential drug use possibilities among girls and older students.

Effectiveness evaluation of the school-based drug prevention program #Tamojunto2.0: protocol of a cluster randomized controlled trial

Background

The European school-based drug addiction prevention program Unplugged was adapted to the Brazilian context by the Ministry of Health and renamed #Tamojunto. Its first implementations, in the form of a public policy in Brazil, showed contradictory and different effects from those observed in Europe. Adaptations were made to #Tamojunto in 2018 to reintroduce the essential content of the original program.

Methods

A parallel, two-arm, randomized controlled trial (RCT) will be conducted to evaluate the effectiveness of the new version of the school-based government program #Tamojunto2.0 for the prevention of drug use among 8th grade middle school students from 70 public schools in three Brazilian cities, totaling approximately 6.300 participating students distributed in 210 classes. For intervention, the experimental group will receive the 12 lessons of the #Tamojunto2.0 program under the supervision of a Brazilian Ministry of Health team. The control group will not receive any intervention. Information will be collected from the students at three time points: preintervention and 9 and 18 months postintervention. Multilevel analyses will be performed using the Gllamm Stata program to assess simultaneous differences in prevalence, in time and among groups for the outcomes of interest. Structural equation modeling will be used to evaluate the effectiveness of the intervention in changing the behavioral patterns of the adolescents through latent transition analysis. The effect of the mediators involved in the program effectiveness outcomes will also be analyzed. The program doses applied in all classes of the intervention group will be collected using a form completed by the teacher at the end of each lesson, indicating the activities taught and not taught in each lesson.

Discussion

This study will show whether the #Tamojunto2.0 program can be expanded as a public policy for all schools with the aim of preventing drug use among Brazilian students.

Adverse childhood experiences and consumption of alcohol, tobacco and illicit drugs among adolescents of a Brazilian birth cohort

The objective of this study was to investigate the association between adverse childhood experiences (ACEs) and the use of alcohol, tobacco and illicit drugs among adolescents from a Brazilian cohort. The occurrence of five ACEs, the use of alcohol and tobacco and trying illicit drugs were investigated in the 1993 Pelotas birth cohort at the age of 15 (n = 4,230). A score was created for the ACEs and their association with the use of substances was evaluated. Around 25% of adolescents consumed alcohol, 6% smoked and 2.1% reported having used drugs at least once in their lives. The ACEs were associated with the use of alcohol, tobacco and illicit drugs. A dose-response relation between the number of ACEs and the substance use was found, particularly with regard to illicit drugs. The occurrence of ACEs was positively associated with the use of alcohol, tobacco and illicit drugs among adolescents and the risk may be different for men and women. These results point to the fact that strategies for preventing the use of substances should include interventions both among adolescents and within the family environment.

Psychoactive substances use and associated factors among middle and high school students in the North Center of Morocco: a cross-sectional questionnaire survey

BACKGROUND

Data on psychoactive substance (PAS) consumption among adolescents in the North Center of Morocco are not at all available. Therefore, the current study aimed at investigating the prevalence and the determinants of psychoactive substances use among middle and high school students in this region.

METHODS

A cross-sectional study was conducted from April 2012 to November 2013 in public middle and high schools in the North Central Region of Morocco. An anonymous self-administered questionnaire was used to assess psychoactive substances use among a representative sample of school students from the 7th to the 12th grade, aged 11-23 years, selected by stratified cluster random sampling. Factors associated with psychoactive substance use were identified using multivariate stepwise logistic regression analyses.

RESULTS

A total of 3020 school students completed the questionnaires, 53.0 % of which were males. The overall lifetime smoking prevalence was 16.1 %. The lifetime, annual and past month rates of any psychoactive substance use among the study subjects were 9.3, 7.5, and 6.3 % respectively. Cannabis recorded the highest lifetime prevalence of 8.1 %, followed by alcohol 4.3 %, inhalants 1.7 %, psychotropic substances without medical prescription 1.0, cocaine 0.7, heroine 0.3, and amphetamine with only 0.2 %. Psychoactive substance use was associated with males more than females. The risk factors identified by multivariate stepwise logistic regression analyses were being male, studying in secondary school level, smoking tobacco, living with a family member who uses tobacco, and feeling insecure within the family.

CONCLUSIONS

The prevalence among all school students reported by the current study was comparable to the national prevalence. Efforts to initiate psychoactive substance prevention programs among school students should be made by designing such programs based on the significant factors associated with psychoactive substance use identified in this study.
