Trends in cannabis use among justice-involved youth in the United States, 2002-2017.

BACKGROUND: Little is known regarding trends in cannabis use among justice-involved youth. We hypothesize that cannabis use will be higher over time among justice-involved youth who, on average, are more likely to be exposed to and seek out cannabis. OBJECTIVES: The present study compares trends in cannabis use among justice-involved youth (past year) with youth in the general population age 12-17 who have not been arrested in the past year. METHODS: Public-use data as part of the 2002-2017 National Survey on Drug Use and Health (NSDUH), which does not include state-level identifiers, was used. Males constitute 51% of the total sample. Among justice-involved youth, 66.4% were males. We employed logistic regression analyses with survey year as an independent variable and past-year cannabis use as the dependent variable. A series of logistic regressions examined the association between cannabis use and psychosocial and behavioral factors. RESULTS: The prevalence of past-year cannabis use among justice-involved youth (3.09% of the sample) steadily increased from 54% in 2002 to 58% in 2017 (AOR = 1.018, 95% CI = 1.004-1.034), while the concurrent prevalence of cannabis use among youth with no past year arrests decreased from a high of 14% in 2002 to 12% in 2017 (AOR = 0.993, 95% CI = 0.990-0.997). CONCLUSION: Study findings suggest that cannabis use is increasing among justice-involved youth.

A Decline in Propensity Toward Risk Behaviors Among U.S. Adolescents.

PURPOSE: Over the past two decades, substance use, delinquent behaviors, and promiscuous sexual activity have declined substantially among U.S. adolescents. We aimed to determine the extent to which these trends represent declines in a general propensity to engage in risk behaviors (i.e., declines in a latent factor). METHODS: We used Youth Risk Behavior Survey data (1999-2017) (n = 147,800) and examined trends in substance use (e.g., alcohol), delinquency (e.g., fighting), and sexual activity (e.g., number of partners). We conducted two types of analyses stratified by grade (9th/10th vs. 11th/12th) and sex: (1) estimation of year-specific prevalence of each behavior and modeled prevalence changes over time and (2) factor analysis and application of alignment methods to determine changes in the mean of the latent factor over time while correcting for measurement noninvariance. RESULTS: A single factor explained 53% (girls 11th/12th grade) to 62% (boys 9th/10th grade) of the variance in risk behaviors. Average relative annual declines in the prevalence of each behavior-except for weapon carrying-ranged from 1% to 6%. The structure of the latent factor was mostly unchanged over time, with notable exceptions related to differential changes in prevalence for cigarette and cannabis use. Between 1999 and 2017, the mean of the latent factor declined by between .54 and .73 standard deviations. CONCLUSIONS: Results suggest that much of the decline in the prevalence of substance use, delinquent, and sexual behaviors among American youth from 1999 to 2017 reflect an approximately two-thirds standard deviation decline in the mean of a latent risk behavior factor.

Youth homicide: a study of homicide predictor factors in adolescent offenders in custody in the south of Brazil / Homicídio juvenil: fatores preditores em adolescentes privados de liberdade no sul do Brasil

Abstract Objectives To assess the sociodemographic, psychiatric and criminal profile of adolescent offenders complying with temporary custody for homicide/homicide attempt and to compare it to that of the population of adolescents in custody for other crimes. Methods This cross-sectional study was based on the review of the medical records of 74 juvenile offenders in temporary custody at socioeducational agency Fundação de Atendimento Sócio-Educativo do Rio Grande do Sul. For the analysis, variables that presented p < 0.2 were included in multivariate adjustment through logistic regression. Results The sample comprised males only, mostly with white skin color (55.6 vs. 57.9% for homicidal and non-homicidal, respectively) and with a high prevalence of school failure (77.8 vs. 91.2%). There was a high prevalence of family history of delinquency (88 vs. 81%). Only years of study and belonging or not to a criminal organization remained statistically significant in the multivariate model. Conclusion The results show that having fewer years of study and denying belonging to a criminal organization are predictive factors of homicidal behavior in adolescent offenders (both with statistical relevance). The other variables were not statistically significant for this outcome. The present study may serve as a basis for further research, which may improve our understanding of risk factors for juvenile homicide.

Resumo Objetivos Avaliar o perfil sociodemográfico, psiquiátrico e criminal de adolescentes infratores que cumprem internação provisória por homicídio ou tentativa de homicídio e compará-los aos adolescentes privados de liberdade por outros atos infracionais. Métodos Este estudo transversal baseou-se na revisão dos prontuários médicos de 74 adolescentes infratores em internação provisória na Fundação de Atendimento Sócio-Educativo do Rio Grande do Sul. Para a análise, variáveis que apresentaram p <0,2 foram incluídas no ajuste multivariado por meio de regressão logística. Resultados A amostra foi composta apenas por homens, a maioria de pele branca (55,6 versus 57,9% para homicidas e não-homicidas, respectivamente) e com alta prevalência de reprovações escolares (77,8 vs. 91,2%). Houve alta prevalência de antecedentes familiares de delinquência (88 versus 81%). Apenas anos de estudo e pertencimento ou não a uma organização criminosa permaneceram estatisticamente significantes no modelo multivariado. Conclusão Os resultados mostram que ter menos anos de estudo e negar pertencer a uma organização criminosa foram fatores preditivos de comportamento homicida em adolescentes infratores (ambos com relevância estatística). As demais variáveis não foram estatisticamente significativas para esse desfecho. O presente estudo pode servir como base para futuras pesquisas, o que pode melhorar nossa compreensão dos fatores de risco para o homicídio juvenil.

Depression in Justice-involved Youth.

Justice-involved youth are at exceedingly high risk of trauma exposure, multisystem involvement, and mental health distress, including depression. Justice-involved youth carry with them both a high symptom burden and a high cost to society. Both could be reduced through evidence-based prevention and treatment strategies. Effective treatment of mental disorders may reduce future justice involvement, whereas lack of treatment increases likelihood of justice involvement into adulthood. Multiple effective programs exist to improve the lives of justice-involved youth and subsequently decrease the cost to society of detaining and adjudicating these youth within the juvenile justice system.

Sex Differences in the Association Between Cyberbullying Victimization and Mental Health, Substance Use, and Suicidal Ideation in Adolescents.

OBJECTIVE: To examine sex differences in the association between cyberbullying victimization and mental health (psychological distress and delinquency), substance use-related outcomes (drug and tobacco use, binge drinking), and suicide ideation among adolescents. METHOD: Data were obtained from the Ontario Student Drug Use and Health Survey (OSDUHS; 2013, N=10,272, grade 7 to 12). The sample for analysis included 4,940 students with a mean age of 15.1 years (43.3% male). A series of multi-level, binary, logistic regression models were conducted separately for female and male adolescents to quantify the strength of associations between cyberbullying victimization and study outcomes, after accounting for traditional forms of bullying and demographic covariates. RESULTS: Female adolescents reported significantly higher prevalence of cyberbullying victimization (once, 9.4%; twice or more, 13.3%) as compared with male adolescents (once, 8.3%, twice or more, 7.8%). Exposure to cyberbullying victimization was associated with an increased odds for psychological distress, suicide ideation, and delinquency among both female and male adolescents (adjusted odds ratios ranged from 1.76 to 4.63); although, the effects were more pronounced in females. Among females, but not males, the odds of reporting psychological distress, suicide ideation, and delinquency increased (in a step-wise fashion) with more frequent exposure to cyberbullying victimization. Cyberbullying victimization was associated with an increased odds of adolescent substance use only among females. CONCLUSION: Adolescents exposed to cyberbullying victimization demonstrate an increased odds of poorer mental health, substance use outcomes, and suicide ideation. The current study reveals increased risk among female adolescents as compared with male adolescents. These findings lend support for the need to develop and evaluate targeted preventative interventions specifically tailored for female and male adolescents.

Adolescent arrestees detained in police cells: an observational study in the Paris, France, area.

OBJECTIVE: Custody conditions in police cells are often demeaning and considered inappropriate for human beings. The detention of young adolescents in police custody has received little attention. Our study aimed to describe the characteristics of adolescents under 18 detained in custody. METHODS: We studied all arrestees aged 13-17 examined in 1 year (January 01-December 31, 2014) in a suburban district near Paris. We evaluated the proportion of adolescents under 18 among all arrestees detained in custody and their medical history, addictive behaviors, perceived health status, and opinion on custody. RESULTS: Arrestees aged 13-17 accounted for 1859 individuals. They were predominantly males (94%) and accounted for 19% of all examinations in custody. Nearly half of the arrestees aged 13-15 (42%), and two thirds of those aged 16-17 (65%) had been previously detained in police cells. Somatic and psychiatric disorders were reported by 7% and 4%, respectively, of arrestees aged 13-17. Alcohol, tobacco, and cannabis consumption were reported by 5%, 24%, and 12%, respectively, of arrestees aged 13-15. These proportions were lower than the 16%, 50%, and 35%, respectively, reported by arrestees aged 16-17 (p < 0.0001). Assaults were reported by 18% of arrestees aged 13-17. They had a fair, bad, or very bad opinion on custody in 43% of cases. CONCLUSION: The detention of adolescents in police stations is commonly associated with assaults at the time of arrest. High proportions of adolescent arrestees smoke tobacco or cannabis. We suggest that the medical examination in custody could be an opportunity for adolescents to initiate access to health care.

Children detained in French police cells.

AIM: Police custody is detention in response to a suspicion of crime. In France, until the age of 13, pre-trial detention and police custody are not allowed. We aimed to evaluate the practical implementation of police detention of children aged between 10 and 12 years and describe the medical characteristics and history, perceived health status and opinion on custody of the potentially affected children. METHODS: A descriptive study was conducted in a French reference regional department of forensic medicine at the time of medical examination in police cells among arrestees younger than 13 years old examined over a 5-year period (1 January 2011-31 December 2015). RESULTS: Children aged 10-12 years (n = 60; males, 48, 80%), accounting for 60 of 57 687 examined arrestees (0.1%), were examined over the study period. Six individuals (10%) were arrested twice or more times during the study period (for a total of 76 detentions analysed). The most common suspected crimes were theft or robbery (42/76, 55%) and physical assault (22/76, 29%). Arrestees had a favourable opinion of custody in 33 of 76 cases (43%). Children reported physical assault by the police in 6 of 76 cases (8%), and the physicians observed recent traumatic injuries in 7 of 76 cases (9%). Daily tobacco consumption was reported by 4 of 60 children (7%). No child was considered unfit for detention by the physician. CONCLUSIONS: Children aged 10-12 years suspected of serious crimes accounted for 0.1% of detained individuals in police cells. Although infrequent, such situations are a matter of concern.

School Disciplinary Style and Adolescent Health.

PURPOSE: Parenting style is strongly associated with adolescent health. However, little is known about how school disciplinary style relates to health. We categorized adolescents' perceptions of their schools as authoritative, authoritarian, permissive, or neglectful, and test whether perceived school disciplinary style is associated with health. METHODS: We analyze data from the RISE Up study (Reducing Health Inequities Through Social and Educational Change Follow-up), comprised of baseline (eighth grade) and 2-year follow-up surveys (10th grade) from 1,159 low-income minority adolescents in Los Angeles attending 157 schools. At 10th grade, students' ratings of school support and structure were used to categorize perceived school disciplinary style as authoritative (highest tertile for support and structure), authoritarian (low support, high structure), permissive (high support, low structure), neglectful (low on both dimensions), and average (middle tertile on either dimension). Mixed effects logistic regressions controlling for sociodemographic factors, parenting style, grades, and baseline health tested whether school disciplinary style was associated with substance use, violence, bullying, and depression symptoms. RESULTS: Risky behaviors varied by school disciplinary style. After adjusting for covariates, compared with an average school disciplinary style, a neglectful school was associated with higher odds of substance use (adjusted odds ratio [AOR] 2.3, p < .001) and bullying (AOR 1.5, p = .02), a permissive school was associated with higher odds of depression symptoms (AOR 2.1, p = .04), and an authoritative school was associated with lower odds of substance use (AOR .6, p = .049), violence (AOR .6, p = .03), and bullying (AOR .5, p = .001). CONCLUSIONS: Structured and supportive school environments may impact the health of vulnerable adolescents.

Predicting Persistent, Limited, and Delayed Problematic Cannabis Use in Early Adulthood: Findings From a Longitudinal Study.

OBJECTIVE: To identify risk profiles associated with patterns of problematic cannabis use in early adulthood. METHOD: Data came from 1,229 participants in the Great Smoky Mountains Study, a prospective 20-year cohort study from 1993 to 2015 that is representative of western North Carolina with yearly assessments conducted from ages 9 and 16 years, and assessments at ages 19, 21, 26, and 30 years. Patterns of problematic cannabis use (i.e., DSM-5 cannabis use disorder or daily use) in early adulthood included the following: nonproblematic use in late adolescence (ages 19-21) and early adulthood (ages 26-30); limited problematic use in late adolescence only; persistent problematic use in late adolescence and early adulthood; and delayed problematic use in early adulthood only. Multinominal logistic regression models examined pairwise associations between these patterns and risk factors in childhood/early adolescence (ages 9-16) and late adolescence (ages 19-21). Risk factors included psychiatric disorders (e.g., anxiety, depressive), other substance use (smoking, alcohol, illicit drugs), and challenging social factors (e.g., low socioeconomic status, family functioning, peers). Sex and race/ethnicity (white, African American, American Indian) interactions were tested. RESULTS: The persistent pattern (6.7% of sample) was characterized by more anxiety disorders across development and more DSM-5 CUD symptoms during late adolescence compared to the limited pattern (13.3%), which, in turn, had more childhood family instability and dysfunction. The delayed pattern (3.7%) was characterized by more externalizing disorders, maltreatment, and peer bullying in childhood compared to those in nonproblematic users. There were no significant interactions of sex or race/ethnicity. CONCLUSION: Problematic cannabis use patterns during early adulthood have distinctive risk profiles, which may be useful in tailoring targeted interventions.

Tests of linear and nonlinear relations between cumulative contextual risk at birth and psychosocial problems during adolescence.

This study tested whether there are linear or nonlinear relations between prenatal/birth cumulative risk and psychosocial outcomes during adolescence. Participants (n = 6963) were taken from the Northern Finland Birth Cohort Study 1986. The majority of participants did not experience any contextual risk factors around the time of the target child's birth (58.1%). Even in this low-risk sample, cumulative contextual risk assessed around the time of birth was related to seven different psychosocial outcomes 16 years later. There was some evidence for nonlinear effects, but only for substance-related outcomes; however, the form of the association depended on how the cumulative risk index was calculated. Gender did not moderate the relation between cumulative risk and any of the adolescent psychosocial outcomes. Results highlight the potential value of using the cumulative risk framework for identifying children at birth who are at risk for a range of poor psychosocial outcomes during adolescence.

A frailty model for recurrent events during alternating restraint and non-restraint time periods.

We consider recurrent events of the same type that occur during alternating restraint and non-restraint time periods. This research is motivated by a study on juvenile recidivism, where the probationers were followed for re-offenses during alternating placement periods and free-time periods. During the placement periods, the probationers were under a restricted environment with direct supervision of the probation officers. During the free-time periods, the probationers were released to home and not under direct supervision. Although re-offenses can occur during both types of time periods, the intensities of the re-offenses are very different. Thus, these two types of time periods should be modeled differently. The same data structure also arises in many biomedical settings, as exemplified by tumor metastases during chemotherapy and chemo-free periods. In this paper, we propose a joint modeling framework that explicitly accounts for the different types of time periods, as well as the within-subject dependence during the same type and between different types of time periods. The estimation procedure is implemented in SAS and is easily accessible to practical investigators. We evaluate the proposed method through simulation studies under several realistic scenarios and demonstrate the feasibility of the proposed method by applying it to the juvenile recidivism dataset.

Substance use in rural adolescents: The impact of social capital, anti-social capital, and social capital deprivation.

Middle- and high-school substance use is a pressing public health problem in the United States. Despite similar or, in some cases, elevated rates of substance use among rural youth, much of the extant research on adolescent substance use has focused on urban areas. The current study aims to uncover forms of social capital (e.g., ethnic identity), social capital deprivation (e.g., parent-child conflict), and anti-social capital (e.g., delinquent friends) that impact the use of alcohol, cigarettes, and marijuana in a sample of middle- and high-school students from the rural south. It was hypothesized that social capital factors would be associated with decreased substance use while social capital deprivation and anti-social capital factors would be associated with increased substance use. The hypotheses were tested using logistic regression models with generalized estimating equations. The findings indicated that for middle school youth, anti-social capital in the form of aggression and delinquent friends was significantly associated with an increased likelihood of using alcohol, cigarettes, and marijuana. For high school students, anti-social capital in the form of aggression and delinquent friends and social capital deprivation in the form of neighborhood crime were significantly associated with an increased likelihood of using alcohol, cigarettes, and marijuana. Violent behavior was also significantly associated with an increased likelihood of using marijuana. Females reported less substance use in both middle and high school; reports of use increased with age. Implications are discussed. Given the salience of social capital deprivation, substance use programs should emphasize the skills necessary to avoid or disengage from antisocial relationships.

Social support as a buffer between discrimination and cigarette use in juvenile offenders.

Cigarette use is a prominent problem in juvenile offenders, leading to negative health outcomes and substance use. One interesting precipitator of cigarette use in this population is discrimination. Social support could potentially buffer the positive relationship between cigarette use and discrimination in juvenile offenders, which could be dependent on the context in which the discrimination is experienced, such as peer, institutional (e.g., stores, restaurants), or educational contexts. The present study explored the relationship between three types of discrimination, social support, and smoking outcomes among 112 detained and probated juvenile offenders (mean age=16.24, SD=2.11, 29.2% female, 54.9% Caucasian, 40.4% detention, 53.8% smokers). Results indicated that the relationship between institutional discrimination (OR=-0.10, p=0.005) and peer discrimination (OR=-0.11, p=0.01) were significantly moderated by social support, with a higher likelihood of being a smoker, compared to a non-smoker at higher levels of peer and institutional discrimination. Further, based on a moderated regression analysis, results indicated that youth who experienced greater educational discrimination and lower levels of social support, they were at higher risk of nicotine addiction (b=-0.09, p=0.03). Overall, results indicate that varying avenues of social support, such as parent, peer, and teacher support, can mitigate negative effects of discrimination on juvenile offenders, particularly cigarette use. Addressing discrimination in smoking treatment and prevention in juvenile offenders may be of great utility. Future studies should examine the potential mechanisms underlying the discrimination and cigarette use connection in juvenile offenders.

Continuity of cannabis use and violent offending over the life course.

BACKGROUND: Although the association between cannabis use and violence has been reported in the literature, the precise nature of this relationship, especially the directionality of the association, is unclear. METHOD: Young males from the Cambridge Study of Delinquent Development (n = 411) were followed up between the ages of 8 and 56 years to prospectively investigate the association between cannabis use and violence. A multi-wave (eight assessments, T1-T8) follow-up design was employed that allowed temporal sequencing of the variables of interest and the analysis of violent outcome measures obtained from two sources: (i) criminal records (violent conviction); and (ii) self-reports. A combination of analytic approaches allowing inferences as to the directionality of associations was employed, including multivariate logistic regression analysis, fixed-effects analysis and cross-lagged modelling. RESULTS: Multivariable logistic regression revealed that compared with never-users, continued exposure to cannabis (use at age 18, 32 and 48 years) was associated with a higher risk of subsequent violent behaviour, as indexed by convictions [odds ratio (OR) 7.1, 95% confidence interval (CI) 2.19-23.59] or self-reports (OR 8.9, 95% CI 2.37-46.21). This effect persisted after controlling for other putative risk factors for violence. In predicting violence, fixed-effects analysis and cross-lagged modelling further indicated that this effect could not be explained by other unobserved time-invariant factors. Furthermore, these analyses uncovered a bi-directional relationship between cannabis use and violence. CONCLUSIONS: Together, these results provide strong indication that cannabis use predicts subsequent violent offending, suggesting a possible causal effect, and provide empirical evidence that may have implications for public policy.

Grit: A Potential Protective Factor Against Substance Use and Other Risk Behaviors Among Latino Adolescents.

OBJECTIVE: Grit, defined as "working strenuously toward challenges, maintaining effort and interest over years despite failure, adversity, and plateaus in progress," is strongly associated with academic achievement and life success and may also be associated with health outcomes and behaviors. We examined predictors of grit, and the association between grit and health behaviors among at-risk Latino adolescents. METHODS: We analyzed baseline survey data collected in 2013-2014 from a sample of 1270 9th graders in low-income neighborhoods of Los Angeles. We examined factors associated with grit and whether grit is associated with substance use and delinquent behaviors, controlling for adolescent and parent sociodemographic factors. RESULTS: In a sample of mostly Latino adolescents (89.5%), compared to those with low grit, those with high grit had significantly lower odds of alcohol use in the last 30 days (odds ratio 0.30, P < .001), marijuana use (odds ratio 0.21, P < .05), and fighting (odds ratio 0.58, P < .05). Involvement in delinquent behavior was also lower (ß = -0.71, P < .001). Factors associated with more grit included authoritative parenting style, parental employment, and high self-efficacy scores. CONCLUSIONS: Grit may be an important candidate protective factor against substance use and other risk behaviors among Latino adolescents.

The Development and Validation of an Actuarial Risk Assessment Tool for the Prediction of First-Time Offending.

For prevention purposes, it is important that police officers can estimate the risk for delinquency among juveniles who were involved in a criminal offense, but not in the role of a suspect. In the present study, the Youth Actuarial Risk Assessment Tool for First-Time Offending (Y-ARAT-FO) was developed based solely on police records with the aim to enable Dutch police officers to predict the risk for first-time offending. For the construction of this initial screening instrument, an Exhaustive Chi-squared Automatic Interaction Detector (Exhaustive CHAID) analysis was performed on a data set that was retrieved from the Dutch police system. The Y-ARAT-FO was developed on a sample of 1,368 juveniles and validated on a different sample of 886 juveniles showing moderate predictive accuracy in the validation sample (area under the receiver operating characteristic curve [AUC] = .728). The predictive accuracy of the Y-ARAT-FO was considered sufficient to justify its use as an initial screening instrument by the Dutch police.

Factors associated with recidivism among adolescents girls in conflict with the law in an institution in Brasília, Federal District, Brazil / Fatores associados à reincidência entre adolescentes femininas em conflito com a lei de uma instituição de Brasília, Distrito Federal, Brasil / Factores asociados a la reincidencia entre adolescentes mujeres en conflicto con la ley de una institución de Brasília, Distrito Federal, Brasil

Abstract Recidivism is a challenge for the Brazilian socio-educational system because it is associated with personal, social and environmental factors, especially among juvenile offenders. This study examined key characteristics and potential association with recidivism in 391 female adolescent offenders from a correctional institution in Brasília, Federal District, Brazil, between 2004 and 2011. Cross-sectional data on socio-demographics, drug use and offense characteristics from institutional information were examined. Associate factors with recidivism were examined using negative binomial regression analyses. 32.5% of offenders were recidivists at present admission and the mean frequency of recidivism among recidivists was 2.16. About half (53.6%) of the sample reported drug use. After the adjustment, recidivism was positively associated with: age; offender’s drug use; residence status; offense type; and no family drug use. Factors associated with juvenile offenders’ recidivism confirm findings from elsewhere, and should inform targeted interventions in Brazil.

Resumo A reincidência constitui um desafio para o sistema socioeducativo brasileiro por estar associada a fatores pessoais, sociais e ambientais, especialmente entre adolescentes em conflito com a lei. Este estudo verificou as principais características associadas à reincidência em uma amostra de 391 mulheres adolescentes em conflito com a lei em uma unidade de internação de Brasília, Distrito Federal, Brasil, entre 2004-2011. Dados transversais sociodemográficos acerca do uso de drogas e sobre as características do ato infracional foram analisados. Fatores associados à reincidência foram analisados por regressão binomial negativa. Trinta e dois vírgula cinco por cento das adolescentes pesquisadas eram reincidentes e a frequência média de reincidências foi de 2,16. Cinquenta e três vírgula seis por cento da amostra relataram uso de drogas. Após ajuste, reincidir foi positivamente associado à idade, uso de drogas, residência, tipo de ato infracional e não uso de drogas pela família. Nossos achados corroboram com outros contextos mundiais, demonstrando a necessidade de orientação nas intervenções adotadas pelo sistema socioeducativo brasileiro.

Resumen La reincidencia es un reto para el sistema socio-educativo brasileño. Este estudio examinó características claves y su posible asociación con la reincidencia de 391 adolescentes mujeres infractoras en una institución correccional en Brasília, Distrito Federal, Brasil, entre 2004 a 2011. Se examinaron datos transversales socio-demográficos, uso de drogas y las características del delito cometido a partir de la información institucional. Los factores asociados con la reincidencia se obtuvieron por análisis de regresión negativa-binomial. 32,5% de las internas eran reincidentes y la frecuencia media de reincidencia entre las reincidentes era de 2,16. Un 53,6% de la muestra informó consumo de drogas. Después del ajuste, la reincidencia se asoció positivamente con: edad; uso de drogas de la delincuente; estatus de residencia; tipo de delito; el no uso de drogas por parte de la familia. Los factores asociados con la reincidencia de las delincuentes confirman hallazgos de otros estudios, y deberían informar intervenciones específicas sobre esta población en Brasil.

Who receives cannabis use offers: A general population study of adolescents.

BACKGROUND: Drug use is predicated on a combination of "willingness" and "opportunity". That is, independent of any desire to use drugs, a drug use opportunity is required; be it indirect (i.e., being in a drug-use setting) or direct (i.e., receiving a direct drug offer). However, whether some youth are more likely to encounter such direct drug use opportunities is not fully known. AIMS: We examined whether certain characteristics placed adolescents at greater risk for being offered cannabis, after accounting for a number of demographic-, contextual-, interpersonal-, and personal-level risk factors. METHODS: We utilized data from a Norwegian school survey (n=19,309) where the likelihood of receiving cannabis offer in the past year was estimated using logistic regression models. Substantive focus was on the individual and combined effects of personal (i.e., delinquency) and interpersonal (i.e., cannabis-using close friend) risk factors. Separate models were fit for middle- and high-school students. RESULTS: Delinquency was a significant risk factor for receiving cannabis offers, as was a cannabis-using best friend. In addition, peer cannabis use increased the risk of cannabis offers mostly for adolescents on the lower delinquency spectrum, but less so for highly delinquent adolescents. These interaction effects were primarily driven by the middle-school cohort. CONCLUSIONS: Cannabis offers were more likely to be extended to youth of certain high-risk profiles. Targeted prevention strategies can therefore be extended to a general profile of younger adolescents with externalizing problems and cannabis-using peers.

Effects of Communities That Care on Males' and Females' Drug Use and Delinquency 9 Years After Baseline in a Community-Randomized Trial.

UNLABELLED: This study tested sustained effects of the Communities That Care (CTC) prevention system on health-risking behaviors 9 years after baseline in a community-randomized trial involving 24 towns in seven states. Earlier analyses found sustained effects on abstinence from drug use and delinquency through Grade 12 in a panel of fifth graders. At age 19, 91 % (n = 3986) of the living panel completed the survey. Data were analyzed using generalized linear mixed models. The prevalence of lifetime and current substance use and delinquency were the primary outcomes. Secondary outcomes included substance use disorders, major depression, suicidality, educational attainment, and sexual risk behaviors. CTC had a significant overall effect across lifetime measures of the primary outcomes for males, but not for females or the full sample, although lifetime abstinence from delinquency in the full sample was significantly higher in CTC communities (ARR = 1.16). Males in CTC communities also continued to show greater lifetime abstinence from cigarette smoking (ARR = 1.22). CTC did not have a sustained effect on current substance use and delinquency nor did it improve the secondary outcomes at age 19 for either gender. Communities using CTC may need to extend their prevention planning to include the high school years to sustain effects on drug use and delinquency beyond high school for both genders.
