Illicit Substance Use and Delinquency Among Argentine Adolescents: A Latent Class Analysis

Aim: Young adulthood is a period when individuals experiment health risk substances such as illicit substance and tobacco use that may predispose them to sexually transmitted diseases. Minority young adults living in HIV prevalent urban communities are notably more likely to engage in these behaviors. In the United States, minority young adults over-represented with HIV infection. To resolve this problem, the United States Congress has invested over $100million in grants. In the United States, few studies have examined illicit substance and tobacco use among this vulnerable population. This study aimed to evaluate the impact of a comprehensive HIV prevention program (CIHPP) on illicit substance and tobacco use among minority young adults living in a high prevalence of HIV infection urban community. Methods: The data of illicit substance and tobacco use was collected using a survey of a random sample of minority young adults who participated in the CIHPP. for12-months. Change in illicit substance and tobacco use during 24 months of minority young adults' participation in CIHPP was recorded. The data was analyzed using the latent growth curve (LGC) model within the framework of the structural equation modeling procedure. The evaluation included the change in the intercept and slope of the Mean, Variance, covariance, and predictor variable in three waves for 24months. Result: The average score for illegal substance use of 5.411 decreased significantly over the 24months. Young adults exhibited a low rate of increase in their illicit use substance over the 24months. This finding indicates that the CIHPP was effective in decreasing the substance use of young adults under study. There were significant inter individual differences in the original score of illicit substance use between the young adults at the beginning of the implementation of the CIHPP and its change over time, as the as the minority young adult progressed from the beginning of the CIHPP intervention through the 24 months. Using gender as a predictor of change showed no difference between male and female young adults. For tobacco use, the average score for tobacco (16.631) decreased significantly over the three 24months. There was no meaningful difference between minority young adult males and minority young adult females in illicit substances use at the beginning of CIHPP. However, during CIHPP intervention, minority young adult’s males had an increase in the rate of change in tobacco use than minority young adult females. The mean estimate for tobacco use indicates that the average score for tobacco use increased significantly over the three 12-months periods. The covariance between the intercept and slope factor for tobacco use was statistically significant. Minority young adult males exhibited a higher rate of tobacco use than their female counterparts over the 24 months. This finding suggests that the Comprehensive, integrated HIV prevention program was not effective in decreasing the tobacco use of the minority young adults studied, The variance estimate related 2 Annals of Immunology & Immunotherapy Mongkuo MY, et al. Latent Growth Curve Model Evaluation of Illicit Substance and Tobacco Use among Young Adults in Cumberland County, North Carolina. Ann Immunol Immunother 2020, 2(2): 000124. Copyright© Mongkuo MY, et al. to the intercept and slope for tobacco use is statistically significant (p=.001) suggesting that there were vast inter-individual differences both at the beginning of CIHPP and the rate of change of tobacco use between the minority young adults at the beginning of the implementation of the CIHPP and its rate of change over time, as the young adult progressed from the beginning of the CIHPP intervention through the 24months. Such evidence provides sturdy support for further investigation of variability or heterogeneity related to the growth trajectory. Specifically, the incorporation of time-invariant of change into the model can explain the young adults' tobacco use variability. This incorporation involves testing the latent growth curve model with the demographic or static variable as a time-invariant predictor of change. This study incorporated gender in the LGC model as a predictor of change. The prediction module with gender as predictor found that there was no meaningful difference in illicit substance and tobacco use between minority young adult males and females.

This article was migrated. The article was marked as recommended. Background: The General Medical Council state illicit substance use by medical students is an example of unprofessional behaviour. Previous research has shown the use of illicit substances to exist amongst medical students in the United Kingdom. This research aimed to determine the prevalence of illicit substance use amongst a single cohort of medical students and gather information concerning perceptions of this behaviour. The study sought to quantify the prevalence of illicit substance use within each year of study and gender identity. Methods: An anonymous online questionnaire was employed to conduct this quantitative research. This included nine questions regarding illicit substance use amongst medical students, with three additional demographic questions. The Statistical Product and Service Solutions was utilised to interrogate the data. Results: Out of 927 students in the medical school 201 (21.7%) people completed the questionnaire. 50.7% of respondents reported an any lifetime use of illicit substances, with 20.9% of the cohort reflecting recent illicit substance use within the previous 30 days. Drug use included amphetamines, amyl nitrate, cocaine and ecstasy amongst others. Cannabis was the most commonly used illicit substance, with a lifetime use of 45.8%. Statistical significance was determined for use of illicit use of substances within the male gender and older cohort years of the medical school. Conclusions: The current cohort had a greater prevalence of cannabis use than previously determined amongst medical students. Males and students in older years had higher rates of illicit substance use than their respective demographics. As such, further research may be necessary to investigate the underlying reasons for these findings.

The Hispanic population is the fastest growing minority population in the United States. A growing body of literature suggests Hispanic individuals are at increased risk for substance use disorders. While much of the literature has focused on Hispanic heterosexual individuals, a paucity of literature has focused on Hispanic transgender individuals. More research is warranted on the prevalence and correlates to substance use among Hispanic sexual minorities, in particular Hispanic transgender individuals. The present study sought to examine correlates to lifetime illicit substance use among a national sample of transgender individuals. A secondary analysis of the 2015 Transgender Survey was conducted among 1,473 Hispanic transgender individuals. Weighted analyses reveal that 29% of Hispanic transgender individuals reported lifetime illicit substance use. Significant predictors included age and prior lifetime substance use. Recommendations for health professionals and policy analysts are included.

Contributions of attachment style and perceived social support to lifetime use of illicit substances

Background and aims Adolescence is a period of physical, psychological and socio-cultural transformation, but also of curiosity, experimentation and acquisition. It is mainly during adolescence that people are introduced to the use of legitimate psychoactive substances, such as alcohol and tobacco, as well as illicit substances such as cannabis. Studying its predictors could help deal with this problem more efficiently. We aimed to determine the prevalence of life time illicit substance use and its predictors among Tunisian adolescents. Methods We conducted a cross-sectional study in two public schools in the governorate of Sousse during the 2017/2018 school year. The data were collected by anonymous self-administered questionnaire, then processed and analyzed using the SPSS software version 20. Results A total of 294 students were included. The mean age was of 17.03 years (standard deviation = 1.51). Females represented 56.1% of participants (sex ratio was 0.78). Among respondents: 60 (20.4%) had used illicit substance at least once. Cannabis was the main substance used by 35 (58.3%) students. The average age of the illicit substance use initiation was 16.3 (±1.1) years while it was 15.7 (±1.5) and 14.7 (±1.8) years for alcohol and tobacco use initiation respectively. Proportions of male students and academic failure were significantly more important among illicit substance users than among non users. While the most influential factors on illicit substance use were: alcohol use, and tobacco use (p < 10-3). However, no significant association was found between illicit substance use and video games and internet use. Conclusions This study highlights the strong association between the other risk behaviors and illicit drug use. Future interventions should focus on the whole risk behaviors simultaneously at late adolescence with regard to the environmental context. Key messages Our results highlight the need to better understand behaviors at risk in Tunisia and the perceptions of prevention policies among students. Mainly during adolescence that people are introduced to the use of illicit substances.

Background Illicit substance use among college students represents one of the most complicated social problems. Studying its predictors could help deal with this problem more efficiently. Aims To determine the prevalence of life time illicit substance use and its predictors among Tunisian college students. Methods A cross-sectional study was conducted in five colleges in the region of Sousse, Tunisia in the 2012-2013 school year. A sample of 556 college students responded to an anonymous self-administrated questionnaire. Collected data concerned socio-demographic characteristics and substances use. Results The mean age of students was 21.8 ± 2.2 years. Females represented 51.8% of participants. Among respondents: 31 (5.6%) had used illicit substance at least once. Cannabis was the main substance used by 26 (4.7%) students. The average age of the illicit substance use initiation was 19 (±2.5) years while it was almost 17 (±3) years for both tobacco and alcohol use initiations. Proportions of male students and academic failure were significantly more important among illicit substance users than among non users. While the most influential factors on illicit substance use were: alcohol use, tobacco use and low socioeconomic level. Conclusion This study highlights the strong association between the other risk behaviors and illicit drug use. Future interventions should focus on the whole risk behaviors simultaneously at late adolescence with regard to the environmental context.

This study examined the prevalence and correlates of drug use among emerging adult members of the Los Angeles house and ball community. The associations of lifetime and 90-day illicit drug use with sociodemographic and house and ball community factors were assessed using bivariate analyses and logistic regression. Study participants had high rates of illicit substance use when compared to similar populations. Age was related to lifetime illicit substance use (t = 4.66, p < .05). School enrollment was significantly protective against illicit drug use, even after controlling for age, race, and gender (odds ratio = .88, p < .05, 95% confidence interval 0.18 to 0.98). School enrollment may be an important opportunity for prevention efforts related to illicit substance use and subsequent accumulating HIV risk within this community.

As illicit substance use can present several perioperative concerns, effective means to identify such practices are necessary to ensure patient safety. Identification of illicit substance use in pediatric patients may be problematic as screening may rely on parental reporting. The current study compares answers regarding use of illicit substances between a survey completed by the patient and the preoperative survey completed by parents or guardians. The study included patients presenting for surgery at Nationwide Children's Hospital, ranging in age from 12 to 21 years. After consent, patients completed a survey of six drop-down questions using an iPad. The six questions involved the patient's history of alcohol, tobacco, marijuana, vaping, and opioid use. The results were compared to the answers obtained from the parents during a preoperative phone call. The study cohort included surveys from 250 patients with a median age of 16 years. Survey data showed a statistically higher reporting of substance use or abuse from the patient study survey in comparison to the routine parental preoperative survey. Alcohol report rates were highest with 69 (27.6%) patients reporting use compared to only 5 parental reports (2%). There was a similar discrepancy in reported rates of vaping use (40 patient reports, 16.0% vs. 11 parental reports, 4.4%) and illicit substance use including marijuana (52 patient reports, 20.8% vs. 11 parental reports, 4.4%). Reported rates of tobacco use were lowest among the survey responses with 12 patient reports (4.8%) and 5 parental reports (2.0%). Identifying illicit substance and tobacco use via a phone survey of parents is inaccurate and does not allow for proper identification of use of these substances in patients ≤21 years of age presenting for surgery. An anonymous 2-min survey completed by the patient more correctly identifies these issues.

IntroductionBefore COVID‐19, Native Hawaiians/Pacific Islanders (NH/PI) endured a heavy burden of alcohol, tobacco and other drug (ATOD) use in prior US data. Responding to reports that many NH/PI communities experienced severe COVID‐19 disparities that could exacerbate their ATOD burden, we partnered with NH/PI communities to assess the substance use patterns and treatment needs of diverse NH/PIs during COVID‐19.MethodsCollaborating with NH/PI community organisations across five states with large NH/PI populations, we conducted a large‐scale investigation of NH/PI ATOD use, mental health and treatment need during COVID‐19. Between April and November 2021, NH/PI‐heritage research staff from our community partners collected data involving 306 NH/PI adults using several community‐based recruitment methods (e‐mail, telephone, in‐person) and two survey approaches: online and paper‐and‐pencil. Multivariate regressions were conducted to examine potential predictors of NH/PI alcohol use disorder and need for behavioural health treatment.ResultsDuring COVID‐19, 47% and 22% of NH/PI adults reported current alcohol and cigarette use, while 35% reported lifetime illicit substance use (e.g., cannabis, opioid). Depression and anxiety were high, and alcohol use disorder, major depression and generalised anxiety disorder prevalence were 27%, 27% and 19%, respectively. One‐third of participants reported past‐year treatment need with lifetime illicit substance use, COVID‐19 distress and major depression respectively associating with 3.0, 1.2, and 5.3 times greater adjusted odds for needing treatment.ConclusionsNH/PI adults reported heavy ATOD use, depression, anxiety and treatment need during COVID‐19. Targeted research and treatment services may be warranted to mitigate COVID‐19's negative behavioural health impact on NH/PI communities.

BackgroundThere is a strong association between bipolar disorder (BD) and substance use disorder (SUD). The clinical and functional correlates of SUD in BD are still unclear and little is known about the role of excessive substance use that does not meet SUD criteria. Thus, the aims of the current study were to investigate lifetime rates of illicit substance use in BD relative to the normal population and if there are differences in clinical and functional features between BD patients with and without excessive substance use.Methods125 consecutively recruited BD in- and outpatients from the Oslo University Hospitals and 327 persons randomly drawn from the population in Oslo, Norway participated. Clinical and functional variables were assessed. Excessive substance use was defined as DSM-IV SUD and/or excessive use according to predefined criteria.ResultsThe rate of lifetime illicit substance use was significantly higher among patients compared to the reference population (OR = 3.03, CI = 1.9-4.8, p < .001). Patients with excessive substance use (45% of total) had poorer educational level, occupational status, GAF-scores and medication compliance, with a trend towards higher suicidality rates, compared to patients without. There were no significant group differences in current symptom levels or disease course between groups.ConclusionThe percentage of patients with BD that had tried illicit substances was significantly higher than in the normal population. BD patients with excessive substance use clearly had impaired functioning, but not a worse course of illness compared to patients without excessive substance use. An assessment of substance use beyond SUD criteria in BD is clinically relevant.

Background Impairments in neurocognitive functioning are associated with substance use behavior. Previous studies in neurocognitive predictors of substance use typically use self-report measures rather than neuropsychological performance measures and suffer from low sample sizes and use of clinical diagnostic cut offs. Methods Crossectional data from the HUNT4 Study (Helseundersøkelsen i Trøndelag) was used to study executive neuropsychological performance and self-reported measures of neurocognitive function associated with a history of illicit substance use in a general population sample of young adults in Norway. We performed both between group comparisons and logistic regression modeling and controlled for mental health symptomatology. Results Subjects in our cohort with a self-reported use of illicit substances had significantly higher self-reported mental health and neurocognitive symptom load. A logistic regression model with substance use as response included sex, commission errors and self-reported inattentiveness and anxiety as significant predictors. After 10-fold cross-validation this model achieved a moderate area under the receiver-operator curve of 0.64. To handle the class imbalance typically found in such population data, we also calculated balanced accuracy with a optimal model cut off of 0.234 with a sensitivity of 0.50 and specificity of 0.76 as well as precision recall—area under the curve of 0.28. Conclusions Subtle cognitive dysfunction differentiates subjects with and without a history of illicit substance use. Neurocognitive factors outperformed the effects of depressive symptoms on substance use behavior in this cohort. We highlight the need for using adequate statistical tools for evaluating the performance of models in unbalanced datasets.

Given ever-reducing budgets of community and school substance use prevention programs, there is a call for identifying the first substance in the sequence leading to polydrug use. Examining data from a nationally representative sample of 2835 United States 12th graders, we sought to determine (1) the first substance adolescents use; (2) order in which adolescents progress through alcohol, tobacco, and marijuana use; and (3) impact of age of initial substance use on lifetime and frequency of illicit substance use. Alcohol is the most commonly used substance, and the majority of polysubstance using respondents consumed alcohol prior to tobacco or marijuana initiation. Respondents initiating alcohol use in sixth grade reported significantly greater lifetime illicit substance use (M = 1.9, standard deviation [SD] = 1.7, p < .001) and more frequent illicit substance use (M = 6.0, SD = 6.5, p < .001) than those initiating alcohol use in ninth grade or later. Overall, effect sizes for these differences were large (eta squared = 0.30 and 0.28, respectively). Findings underscore the importance of screening for substance use, even among youth enrolled in elementary/middle school. In addition, school prevention programs should begin in elementary school (third grade) and target alcohol use.

BackgroundSwedish national guidelines recommend that all health care settings systematically screen patients for alcohol use and illicit substance use. When hazardous use is identified, it should immediately be addressed, preferably through brief interventions (BI). It is well known that the prevalence of alcohol use and illicit substance use among psychiatric patients is high, but it is not known to what extent screening and BI are routinely carried out in such clinics.MethodsTwo online surveys investigating the use of screening and BI for alcohol and illicit substances were constructed; one for psychiatric outpatient clinic directors and one for staff at these clinics. The main analyses were calculated as simple frequencies. In secondary analyses, we investigated the associations between substance abuse training, type of clinic and screening/BI delivery. For these analyses, the Chi square test was used.ResultsMost clinic directors reported that they have guidelines to screen for alcohol (93.1%) and illicit substance use (78.9%) at initial assessment. Fifty percent reported having guidelines for delivering BI when identifying hazardous alcohol use (35.9% for hazardous illicit substance use). Among staff, 66.6% reported always screening for alcohol use and 57.8% reported always screening for illicit substance use at initial assessment. Further, 36.7% reported that they usually deliver BI when identifying hazardous alcohol use (35.7% for hazardous illicit substance use). Secondary analyses indicated that staff with substance abuse training were significantly more likely to screen for alcohol use than staff without such training. Further, staff at psychosis clinics were significantly less likely to screen for both alcohol and substance use than staff at both general and specialist psychiatric clinics.ConclusionsMost clinic directors reported having clear guidelines for staff to screen for alcohol use and illicit substance use, but fewer staff members than expected indicated that these guidelines were adhered to. Providing training about substance use disorders for staff may increase use of screening for alcohol use, and psychosis clinics may need to improve their screening routines.

Prior research has found that marriage contributes to desistance from a variety of antisocial behaviors including crime and illicit substance use. However, certain factors including a lack of research on desistance from illicit substance use, a lack of understanding how other relationship status besides marriage, such as cohabitation, contribute to desistance, and gender variation in desistance from crime are obstacles that must be addressed before fully understanding how marriage operates in the desistance process. Using Monitoring the Future Restricted-Use Panel Data, this study utilized multi-level models to examine the relationship between marital status and engaging in any illicit substance use and if these effects vary by individuals who identify as male or female. The results suggested partial support for Sampson and Laub’s theory, in which marriage was associated with less illicit substance use and cohabitation was associated with more illicit substance use when compared to times when the individual was single. In addition, interactions indicated that illicit substance use is consistently the same regardless of if the individual identifies as male or female, meaning that there is no gender variation in illicit substance use.

Sexual and gender minority youth (SGMY) disproportionately experience intimate partner violence (IPV) and report illicit substance use compared with cisgender heterosexual youth. Cognitive reappraisal strategies have been shown to decrease trauma-exposed individuals' likelihood of engaging in substance use. However, virtually no research has examined the relationship between various forms of IPV, including identity abuse, and illicit substance use, as well as the protective role of cognitive reappraisal among IPV-exposed SGMY. The current study addressed these limitations and examined cognitive reappraisal as a moderator of the associations between various IPV forms and illicit substance use among 149 SGMY (ages 18-25; 28.9% bisexual, 42.3% transgender or gender nonbinary, 45.0% racial and ethnic minority) between 2016 and 2017. Results indicated that many SGMY used cocaine in the past 6 months (24.8%), followed by hallucinogens (24.8%), stimulants (22.8%), and heroin (20.8%). More than half (62.4%) of SGMY experienced psychological abuse, 44.3% physical abuse, and 43.6% identity abuse in the past year. Cognitive reappraisal buffered the associations between two forms of IPV, identity abuse and physical abuse, and illicit substance use among SGMY, underscoring its importance for clinical intervention. Specifically, past year identity abuse and physical abuse were associated with greater illicit substance use only for SGMY with lower cognitive reappraisal, not for youth with higher cognitive reappraisal. This study adds to the burgeoning literature on identity, physical, and psychological forms of IPV and illicit substance use among SGMY. Our findings provide evidence that cognitive reappraisal strategies buffer the effect of identity abuse and physical abuse on illicit drug use among SGMY. These findings shed light on new avenues for clinical intervention that may help to reduce the prevalence of illicit substance use among IPV-exposed SGMY.
