Psychoactive substance use and dependence among Spanish university students: prevalence, correlates, polyconsumption, and comorbidity with depression

Psychoactive substance use and associated factors among Mohammed first university students, Oujda, Morocco: a cross-sectional study

BACKGROUND

The use of psychoactive substances, including tobacco, alcohol, and others, remains a major public health problem. However, few studies have been conducted on Moroccan university students. This study aimed to assess the prevalence and associated factors of substance use among students at Mohammed First University, Oujda, Morocco.

METHODS

We conducted this cross-sectional study with students enrolled at one of the Mohammed First University of Oujda's institutes as part of the 2021-202 academic year. We used a self-administered survey to collect data anonymously. We cleaned the data and then entered it into IBM SPSS Statistics 21 for analysis. Data analysis involved descriptive statistics as well as univariate and multivariate analysis. We considered a P value < 0.05 as the level of significance.

RESULTS

In this study, out of 500 students we asked to complete the survey, 478 responded; the response rate was 95.6%. The average age was 21.1 ± 3.0, and the M/F sex ratio was 0.97. The lifetime prevalence of psychoactive substance use among Oujda University students was 28.7%. The most commonly used substances were tobacco (24.1%), alcohol (15.9%), cannabis (13.4%), sedatives (6.9%), stimulants (5.2%), and cocaine (4.4%). Male sex, age > 20 years, self-financing, school failure (one year repeated or more), the practice of a leisure activity, the presence of a personal medical or psychiatric history, and the presence of a family medical history were all significantly associated with the use of psychoactive substances.

CONCLUSION

Our study revealed a significant prevalence of psychoactive substance use among university students in Oujda, highlighting the need for interventions at various levels. Further analytical studies are necessary to better understand the initiation and maintenance of psychoactive substance use and to identify all associated factors to enhance prevention strategies against substance use disorders.

Mental health and drug use in college students: Should we take action?

BACKGROUND

College students are vulnerable to suffering from anxiety and depression. Moreover, mental disorders can contribute to drug consumption or inappropriate use of prescribed drugs. Studies on this topic in Spanish college students are limited. This work analyses anxiety and depression and psychoactive drug intake pattern in the post-COVID era in college students.

METHODS

An online survey was conducted among college students from UCM (Spain). The survey collected data including demographic, academic student perception, GAD-7 and PHQ-9 scales, and psychoactive substances consumption.

RESULTS

A total of 6798 students were included; 44.1 % (CI95%: 42.9 to 45.3) showed symptoms of severe anxiety and 46.5 % (CI95%: 45.4 to 47.8) symptoms of severe or moderately severe depression. The perception of these symptoms did not change after returning to face-to-face university classes in the post-COVID19 era. Despite the high percentage of cases with clear symptoms of anxiety and depression, most students never had a diagnosis of mental illnesses [anxiety 69.2 % (CI95%: 68.1 to 70.3) and depression 78.1 % (CI95%: 77.1 to 79.1)]. Regarding psychoactive substances, valerian, melatonin, diazepam, and lorazepam were the most consumed. The most worrying issue was the consumption of diazepam, 10.8 % (CI95%: 9.8 to 11.8), and lorazepam, 7.7 % (CI95%: 6.9 to 8.6) without medical prescription. Among illicit drugs, cannabis is the most consumed.

LIMITATIONS

The study was based on an online survey.

CONCLUSIONS

The high prevalence of anxiety and depression aligned with poor medical diagnosis and high intake of psychoactive drugs should not be underestimated. University policies should be implemented to improve the well-being of students.

Assessment of the Relationship of Depression With Tobacco and Caffeine Use Among University Students: A Cross-Sectional Study

Background

University students are at a higher risk of using cognitive enhancers and psychoactive substances. Depression is associated with a noticeable decline in academic performance and can increase the risk of substance use. Due to sociopolitical issues, the use of cognitive enhancers and psychoactive substances among Palestinians has spread in the last decade. However, depression among tobacco and caffeine users remains underrecognized and neglected.

Methodology

A self-administrated questionnaire and the Beck Depression Inventory were used to assess the association of depression and the use of cognitive enhancers and psychoactive substances among university students at An-Najah National University in 2020.

Results

The response rate to the questionnaires was 78.8% (n = 1,051; 38.8% males, 61.2% females). The overall prevalence of depression was high (30.6% males, 34.7% females). The prevalence of cigarette smoking (39.2% males, 3.9% females), waterpipe smoking (43.1% males, 21.6% females), energy drink consumption (59.6% males, 29.7% females), coffee consumption (85.5% for each gender), tea consumption, and chocolate consumption was high, with significant differences in accordance to gender and academic fields. The multinomial logistic regression results revealed that cigarette smokers were more likely to have a higher risk of severe (odds ratio [OR] = 4.5, p = 0.001), moderate (OR = 3.27, p < 0.001), and mild depression (OR = 2.24, p = 0.002) than non-smokers. Severe depression was less prevalent among medical students than health sciences and non-medical students (OR = 0.215, p = 0.015). Moreover, males were less likely to have moderate (OR = 0.5, p = 0.012) and mild (OR = 0.48, p = 0.001) depression than females.

Conclusions

Overall, the results of this study revealed the high prevalence of depression and the detrimental effects of smoking on students. Moreover, the findings suggest the urgent need to address depression and risk factors among Palestinian university students by educating them about mental health, identifying high-risk students, and offering easily accessible psychological help. Further, it is crucial to broaden the focus of studies to include students from various academic fields instead of focusing on medical students.

Prevalence and factors associated with depression among higher secondary school adolescents of Pokhara Metropolitan, Nepal: a cross-sectional study

OBJECTIVE

This study examined the prevalence and factors associated with depression among adolescents attending higher secondary schools in the Pokhara Metropolitan City of Nepal.

DESIGN

A cross-sectional study design was adopted.

SETTING

Four randomly selected higher secondary schools of Pokhara Metropolitan, Nepal.

PARTICIPANTS

312 randomly sampled higher secondary school students.

METHODS

The Center for Epidemiologic Studies Depression Scale was used to assess the level of depression among students. The data collected through a self-administered questionnaire were analysed using descriptive statistical methods such as frequency and percentage. χ² test and unadjusted OR (UOR) were calculated to assess the statistical relationship between depression and various variables at 95% CI, with level of significance at p<0.05.

RESULTS

The study found a high prevalence of depression among high school students, with more than two-fifths (44.2%) of students having depression. Furthermore, almost a quarter (25.3%) of the students were noted to have mild depression and 18.9% of the students expressed major depression. Students who had low perceived social support (UOR: 3.604; 95% CI 2.088 to 6.220), did not share their problems with anyone (UOR: 1.931; 95% CI 1.228 to 3.038) and had low self-esteem (UOR: 5.282; 95% CI 2.994 to 9.319) were at higher odds of being depressed.

CONCLUSION

A high prevalence of depression was observed among high school students. It was also observed that students' level of perceived social support, self-esteem and help-seeking behaviour are somehow related to their mental well-being. Hence, improving social support and self-esteem may alleviate depression and mental distress among these adolescents.

Prevalence of, Factors Associated with and Level of Dependence of Psychoactive Substance Use among Mekelle University Students, Ethiopia

Background: Psychoactive substance use is a major public health concern globally. Though youth attending higher education institutions are considered particularly vulnerable to psychoactive substances, there is a paucity of evidence in Ethiopia. We aimed to determine the prevalence of psychoactive substance use, factors associated with psychoactive substance use and level of dependence among Mekelle University undergraduate students in Ethiopia. Methods: An institution-based quantitative cross-sectional survey was used to randomly (using multistage sampling) invite 1220 undergraduate students in April and May 2017 to participate. Multinomial logistic regression was used to identify factors associated with psychoactive substance use. Level of dependence was determined using the WHO’s Alcohol, Smoking and Substance Involvement Screening Test classification. Results: Among the eligible students approached, 1214 participants completed the survey, which yields a 99.5% response rate. The lifetime prevalence of psychoactive substance use was 66.5% (95% Confidence Interval (CI) = 64% to 69%) while the current prevalence was 49% (95% CI = 46% to 52%). A history of, but not current, psychoactive substance use was reported by 18%, while 33.5% reported never having used psychoactive substances. The current prevalence of alcohol use was 35.5%, tobacco 7.8% and khat 5.7%. Of the current users, 17% (95% CI = 14% to 20%) were at a moderate to high risk of dependency. Being over 21 years of age (adjusted odds ratio (AOR) = 1.6, 95% CI = 1.37 to 2.25), male (AOR = 3.13; 95% CI = 2.26 to 4.34), living in urban areas (AOR = 2.39, 95% CI = 1.77 to 3.23), an Orthodox Christian (AOR = 7.55, 95% CI = 4.56 to 12.48), and being in their 3rd year (AOR = 2.3, 95% CI = 1.49 to 3.55), 4th year (AOR = 2.0, 95% CI = 1.2 to 3.51) and 5th year (AOR = 4.0, 95% CI = 2.81 to 7.67) at university were associated with currently using psychoactive substances. Being male and Orthodox Christian was associated with being an ex-smoker. Conclusions: Approximately half of Mekelle University undergraduate students were using psychoactive substances with almost one in five at risk of dependency. The likelihood of use increased with seniority. Evidence-based strategies are needed to prevent school-aged children from using psychoactive substances and university students becoming dependent on substances. Interventions designed to stop current psychoactive substance use may also have promise for reducing dependency.

Tobacco and cannabis use in college students are predicted by sex-dimorphic interactions between MAOA genotype and child abuse

BACKGROUND

Postsecondary students in Western countries exhibit a high prevalence of cannabis and tobacco use disorders. The etiology of these problems is contributed by several psychosocial factors, including childhood adversity and trauma; however, the mechanisms whereby these environmental determinants predispose to the use of these substances remain elusive, due to our poor knowledge of genetic and biological moderators. Converging evidence points to the monoamine oxidase A (MAOA) gene as a moderator of the effects of lifetime stress on the initiation of substance use.

AIMS

Building on these premises, in this study, we analyzed whether MAOA upstream variable number tandem repeat (uVNTR) alleles interact with child maltreatment history to predict for lifetime cannabis and tobacco consumption.

MATERIALS AND METHODS

Five hundred college students (age: 18-25 years) from a large Midwestern University were surveyed for their child maltreatment history (encompassing emotional, physical, and sexual abuse, as well as emotional and physical neglect) and lifetime consumption of cannabis and tobacco. Saliva samples were obtained to determine the MAOA uVNTR genotype of each participant.

RESULTS

In female students, lifetime tobacco and cannabis use was predicted by the interaction of physical and emotional abuse with high-activity MAOA allelic variants; conversely, in males, the interaction of low-activity MAOA alleles and physical abuse was associated with lifetime use of tobacco, but not cannabis.

DISCUSSION

These findings collectively suggest that the vulnerability to smoke tobacco and cannabis is predicted by sex-dimorphic interactions of MAOA gene with childhood abuse.

CONCLUSION

These biosocial underpinnings of tobacco and cannabis use may prove important in the development of novel personalized preventive strategies for substance use disorders in adolescents.

Prevalence and correlates of substance use among psychiatric inpatients

PURPOSE

This study aimed at examining correlates of substance use among patients diagnosed with psychiatric disorders in Jordan.

METHODS

This study used a nonexperimental descriptive survey design. Data were collected through using DUSI-R scale obtained through a self-designed questionnaire. A total of (203) subjects satisfied the inclusion criteria.

RESULTS

Most used substances prior to admission were caffeine (78.2%), cigarette (60.9%), and alcohol (22.2%), while the least were heroin (1.2%) and inhalants (0.08%). Patients diagnosed with schizophrenia had higher percentages among all other disorders (n = 16, 21.9%), although there was no statistical difference among patients related to their psychiatric disorders.

CONCLUSION

We recommend that mental health professionals be equipped with necessary skills to manage substance use among patients with psychiatric disorders.

Exposure to Psychoactive Compounds amongst Students of Medical University

OBJECTIVE

The aim of this study was to assess the frequency of exposure to psychoactive compounds amongst students of the Medical University of Bialystok.

METHOD

This cross-sectional study included 504 students selected by means of stratified sampling based on the university faculty, study discipline and year, and participant's gender.

RESULTS

Nearly three fourths of our respondents have contact with their student colleagues who use psychoactive compounds, or have heard that such individuals exist. Approximately one fourth of the students declared that they considered using psychoactive compounds at least once. Marijuana and hashish were the psychoactive compounds our respondents used most frequently. Median age of the first contact with these substances was 18 years. Alarmingly high fraction of respondents declared that most of psychoactive compounds included in the study is easily available and obtaining them would not take them longer than one day. Furthermore, 15% of respondents admitted to being involved in the distribution of psychoactive compounds.

CONCLUSION

The exposure of medical university students to psychoactive compounds represents similar problem as in their peers studying other disciplines. However, in view of its specific consequences (including potential threat to patients' health and life), the problem should not be underestimated.

Introduction to the special issue "Pharmacotherapies for the treatment of alcohol abuse and dependence" and a summary of patents targeting other neurotransmitter systems

This paper introduces the Special Section: Pharmacotherapies for the Treatment of Alcohol Abuse and Dependence and provides a summary of patents targeting neurotransmitter systems not covered in the other four chapters. The World Health Organization notes that alcoholic-type drinking results in 2.5 million deaths per year, and these deaths occur to a disproportionately greater extent among adolescents and young adults. Developing a pharmacological treatment targeting alcohol abuse and dependence is complicated by (a) the heterogeneous nature of the disease(s), (b) alcohol affecting multiple neurotransmitter and neuromodulator systems, and (c) alcohol affecting multiple organ systems which in turn influence the function of the central nervous system. Presently, the USA Federal Drug Administration has approved three pharmacotherapies for alcoholism: disulfiram, naltrexone, and acamprosate. This chapter provides a summary of the following systems, which are not covered in the accompanying chapters; alcohol and acetaldehyde metabolism, opioid, glycinergic, GABA-A, neurosteroid, dopaminergic, serotonergic, and endocannabinoid, as well as patents targeting these systems for the treatment of alcoholism. Finally, an overview is presented on the use of pharmacogenetics and pharmacogenomics in tailoring treatments for certain subpopulations of alcoholics, which is expected to continue in the future.

A longitudinal investigation of depressive symptoms in undergraduate students of pharmacy in Syria

This prospective longitudinal study investigated depressive symptoms and its association with students' demographic, academic, and health factors in undergraduate students of pharmacy in Syria. Students attending any year (1st to 5th year) were assessed in the first semester (time 1) and in the second semester (time 2). An academic year comprises two semesters of 16 weeks each. Data for 450 students were analyzed at time 1, and 262 students were assessed at the two time points. Our results showed that most of the students experienced depressive symptoms, with a substantial percentage presenting moderate to severe levels of symptoms (35% or 450 students at time 1; 23% or 262 students at time 2). Across the two semesters, a significant decrease in depressive symptoms was observed for students with complete data at the two time points. Depressive symptoms at time 2 increased significantly with increasing depressive scores at time 1 and decreasing students' expectations about their academic performance. Our results support the clear need for dynamic, full-time, and accessible psychological services at the university to promote and assess mental health and to deliver psychological interventions to students at need.
