RESUMEN
BACKGROUND: In 2006, Brazil implemented the National Policy on Integrative and Complementary Practices of the SUS. and in 2015, the Brazilian Ministry of Health issued a reinforcement to this policy to increase access to integrative and complementary health practices (ICHP). In this study, we described the prevalence of ICHP in Brazilian adults according to their sociodemographic characteristics, self-perceived health, and chronic diseases. METHODS: This is a nationally representative cross-sectional survey including 64,194 participants from the 2019 Brazilian National Health Survey. Types of ICHP were categorized according to their purposes: health promotion (Tai chi/Lian gong/Qi gong, yoga, meditation, and integrative community therapy) or therapeutic practices (acupuncture, auricular acupressure, herbal treatment and phytotherapy, and homeopathy). Participants were classified as non-practitioners and practitioners, who in turn were grouped according to use of ICHP in the last 12 months: only used health promotion practices (HPP); only used therapeutic practices (TP); used both (HPTP). Multinomial logistic regressions were performed to estimate the associations of ICHP with sociodemographic characteristics, self-perceived health status, and chronic diseases. RESULTS: Brazilian adults showed an ICHP use prevalence of 6.13% [95%CI = 5.75-6.54]. Compared to non-practitioners, women and middle-aged adults were more likely to use any ICHP. Afro-Brazilians were less likely to use both HPP and HPTP, whereas Indigenous people were more likely to use both HPP and TP. We found a positive gradient of association among participants with higher income and educational attainment and access to any ICHP. People from rural areas and those with negative self-perceived health were more likely to use TP. Participants with arthritis/rheumatism, chronic back problems, and depression were more likely to use any ICHP. CONCLUSIONS: We found that 6% of Brazilian adults reported using ICHP in the previous 12 months. Women, middle-aged individuals, chronic patients, people with depression, and wealthier Brazilians are more likely to use any type of ICHP. Of note, rather than suggesting to expand the offer of these practices in the Brazilian public health system, this study diagnosed Brazilians' behavior of seeking for complementary healthcare.

The present study investigated how intervention might alter the relationship between perpetrating violence and later drug use. A cluster-randomized controlled trial design involving 72 schools (38 intervention, 34 control) and 6390 students attending grades 7 and 8 was employed in Brazil. Drug use and violence were assessed at three points. A random-intercept cross-lagged panel model examined the reciprocal association between drug use and school violence domains across the three data collection waves. For both groups, we found that the cross-lagged effect of perpetration on further drug use in adolescents was stronger than the reverse, but the interrelationship was not statistically significant between #Tamojunto and control schools. The carry-over effects of drug use and violence were also not significantly different between groups. There is a lack of evidence showing that #Tamojunto can modify the dynamics between drug use and school violence across the 21-month period. The direction of the causal effect (i.e., the more perpetration behavior, the more subsequent drug use behavior) is present, but weak in both groups. The trial registration protocol at the national Brazilian Register of Clinical Trials (REBEC) is #RBR-4mnv5g.

This study aimed to examine the impact of maternal depressive symptoms trajectories on 15-year-old adolescents' self-esteem and emotion regulation and test the mediating role of child maltreatment in this association. The 2004 Pelotas Birth Cohort is an ongoing cohort study originally comprised of 4231 live births in a southern Brazilian city. We examined a subsample of 1949 adolescents at age 15 years. Maternal depressive symptoms were assessed using the Edinburgh Postnatal Depression Scale. Trajectories of maternal depression from 3 months until the 11-year follow-up were calculated using a group-based modeling approach. Child maltreatment at age 11 years was measured using the parent-report version of the Parent-Child Conflict Tactics Scale. Adolescent outcomes at age 15 years were assessed by the self-report version of the Rosenberg Self-esteem Scale and the Emotion Regulation Index for Children and Adolescents. Path model analysis was conducted using a structural equation modeling framework in Mplus software. All maternal depression trajectories were negatively associated with offspring self-esteem and emotion regulation compared to the reference group (low depression trajectory). There was a significant indirect effect of maternal depression trajectories on emotion regulation mediated via child maltreatment. No evidence of moderation by sex was found for any pathway. The effects of maternal depression on adolescents' emotion regulation are partly mediated by child maltreatment at age 11.

INTRODUCTION: Given the growing scientific evidence on the detrimental effects of bullying, several prevention programs have been implemented internationally to prevent this behavior among students. Brazil's Educational Program for Drug and Violence Resistance (PROERD) is an adaptation of US' DARE/Keepin' it REAL program, being the most widespread school-based prevention program in the country. However, it has been offered without any effectiveness evaluation. As such, this study evaluates the effectiveness of PROERD in reducing bullying perpetration and victimization among students. METHODS: Two cluster randomized controlled trials were carried out with 4030 students (1727 5th graders and 2303 7th graders) in 30 public schools in São Paulo, Brazil. The intervention group attended 10 PROERD classes taught by trained police officers whereas the control group underwent no intervention. Data were collected by self-administered questionnaires using smartphones at two moments (baseline preintervention and 9-month follow-up). Multilevel analysis included two paradigms, complete cases (CC) and intention-to-treat (ITT), using Full Information Maximum Likelihood (FIML) and Multiple Imputation (MI). RESULTS AND CONCLUSION: Results show no statistical difference between groups, indicating lack of evidence on PROERD's effectiveness in preventing bullying behaviors. The insufficient number of classes on bullying prevention and the lack of cultural adaptation may explain these unexpected results. New in-depth evaluation studies concerning the program's components and process are needed.

This study aimed to evaluate the effectiveness of the drug and violence resistance educational program (PROERD) on short-term secondary outcomes, such as intentions to use drugs, attitudes toward drugs, school experience, and life skills (refusal, decision-making, and communication). Two cluster-randomized controlled trials were conducted in 30 public schools in the city of São Paulo (Brazil) with 4030 students (1727 fifth and 2303 seventh graders). The intervention group attended 10 PROERD classes conducted by trained police officers, whereas the control group received no intervention. PROERD is a Brazilian adaptation of the North American Drug Abuse Resistance Education (DARE) program Keepin' it REAL. Data were collected at two time points: pre-intervention and at 9-month follow-up. Two different paradigms were used in the multilevel analysis, complete case (CC), and intention-to-treat (ITT) analyses, using full information maximum likelihood (FIML). We found mixed results. Although the seventh-year curriculum seems to have positive effects on school experience (coef = 0.093; 95% CI: 0.001, -0.185), it also increases the intention to use cigarettes in the future (OR = 1.93, 95% CI: 1.109, 3.379) and the chances of accepting marijuana (OR = 1.62, 95% CI: 1.03, 2.53), and it appears to slightly reduce decision-making skills among fifth graders (coef = -0.078; 95% CI: -0.131, -0.025). Our results suggest that PROERD implementation and cultural adaptation should be reevaluated to understand why the program does not achieve the expected preventive goals and produces potential iatrogenic effects.

Sexual risk behaviors are closely related to the use of alcohol, tobacco, and other illicit drugs as well as teen dating violence. School-based drug prevention programs that teach social and personal skills could potentially also reduce sexual risk behaviors. We examined the effects of the #Tamojunto program on youth sexual risk behaviors. A randomized controlled trial was conducted with 6391 7th and 8th grade students in 72 public schools in six Brazilian cities. Baseline data were collected prior to program implementation. Two waves of follow-up assessments occurred after 9 and 21 months. Analyses were performed taking into account the multilevel structure of the data. We used intention-to-treat to evaluate changes in the prevalence of sexual risk behaviors over time and between groups. Adolescent age ranged from 11 to 15 years, with a mean of 12.6 ± 0.8 years, and 51.0% were female. Among all participants, receipt of #Tamojunto was associated with higher risk of lifetime sex at 21 months follow-up (OR 1.27, 95% CI [1.03, 1.56]). Among girls, at 9 months follow-up, the program was associated with higher likelihood of having engaged in sex in the last month (OR 1.76, 95% CI [1.13, 2.74]). At 21 months follow-up, girls receiving the program were more likely to report engaging in condomless sex in the last month (OR 1.64, 95% CI [1.07, 2.50]). #Tamojunto may be ineffective and possibly harmful for preventing sexual risk behaviors, especially among girls. We suggest further investigation of the possible mediating role of life skills intervention components on girl's sexual behaviors.

OBJECTIVE: To assess the association between drinking behaviors during the COVID-19 pandemic and quarantine, anxiety symptoms, and sociodemographic characteristics in Latin America and the Caribbean (LAC). METHOD: Data was collected through a cross-sectional online survey (non-probabilistic sample) conducted by the Pan American Health Organization between May 22 and June 30, 2020, in 33 countries and two territories of LAC. Participants were 18 years of age or older and must not have traveled outside of their country since March 15, 2020 (n= 12 328, M age= 38.1 years, 65% female). Four drinking behaviors (online socializing drinking [OSD], drinking with child present [DCP], drinking before 5 p.m. [DB5]), heavy episodic drinking [HED]) were response variables, and quarantining, anxiety symptoms and sociodemographic covariables were explanatory variables. RESULTS: Quarantine was positively associated with a higher frequency of OSD and with DCP, but negatively associated with a higher frequency of HED. Anxiety symptoms were associated with a higher frequency of HED, more OSD, and DB5. Higher incomes seemed to be more associated with all the studied drinking behaviors. Women tended to report less DB5 and less HED during the pandemic. CONCLUSIONS: Quarantine during the COVID-19 pandemic seems to affect drinking behavior and mental health indicators like anxiety symptoms. This study is the first effort to measure the consequences of the quarantine on alcohol consumption and mental health in LAC during the COVID-19 pandemic. Considering the associations found, screenings and brief interventions targeting alcohol consumption and mental health are recommended.
RESUMEN
OBJECTIVE: This study's main purpose is to evaluate factors associated with eating disorder (ED) symptoms among Brazilian adolescents. METHOD: The sample consisted of 5,213 students, mean age 13.24 (SD ±0.01), in the eighth grade of 93 public schools from three Brazilian cities. Data were collected through an anonymous self-report questionnaire, assessing: sociodemographics, use of alcohol, tobacco, illicit drugs, binge drinking, bullying, and ED symptoms. We used confirmatory factor analysis and multivariate linear regression. RESULTS: We found that high levels of bullying victimization, binge drinking and the use of unprescribed weight-loss substances were associated with higher levels of ED symptoms to both genders. However, only among girls, the higher age (ß = .10; 95% CI = 0.02; 0.17) and the use of illicit drugs (ß = .21; 95% CI = 0.094; 0.34) were associated with increase in the ED symptoms. DISCUSSION: We demonstrate a significant association of ED symptoms with drug use and bullying, highlighting the importance of addressing these factors in the development of ED prevention strategies.
RESUMEN
The present study examined parenting style dimensions (demandingness and responsiveness) as predictors of adolescent drug use and also evaluated whether parenting styles dimensions moderate the effects of the implemented prevention program. 6.391 students in the 7th and 8th grades at 72 Brazilian public schools participated in a three-wave randomized controlled trial to evaluate a school drug-use prevention program. We used structural equation modeling to test if baseline parenting style dimensions (demandingness and responsiveness) would predict the use of drugs (alcohol, binge drinking, cannabis, inhalants, and tobacco) after 21 months. Additionally, we evaluated an interaction version of the above-described model to test if the effect of the prevention program would be moderated by either or both parenting style dimensions. Higher levels of parent demandingness predicted lower chances of adolescent drug use (e.g., Cigarette use OR 0.76, 95% CI 0.64-0.89); responsiveness on the five outcomes showed p value superior to 0.01. The effect of the #Tamojunto intervention is unlikely to be conditioned to either parenting style dimensions on the assessed outcomes.Clinical trial registration Brazilian Register of Clinical Trials (REBEC): #RBR-4mnv5g ( https://www.ensaiosclinicos.gov.br/rg/?q=tamojunto ).

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. TRIAL REGISTRATION: Brazilian Clinical Trials Registry (RBR-8cnkwq) under the name "Avaliação do Efeito do Programa de Prevenção Escolar ao Uso de Drogas #Tamojunto2.0, Versão 2018", on August 30th, 2018 ( http://www.ensaiosclinicos.gov.br/rg/RBR-8cnkwq/ ).

PURPOSE: The present study examined the roles of parental alcohol use and parental style as predictors of adolescent patterns of drug use. METHODS: 6391 students in the 7th and 8th grades at 72 Brazilian public schools participated in a three-wave randomized controlled trial to evaluate a school drug-use prevention program. Patterns of drug use were identified through two latent class analyses using measures of the adolescents' past-year drug use. Multinomial logistic regression analyses examined whether parental alcohol use and parenting style at baseline predicted patterns of drug use in waves 2 and 3 of the study after controlling for sociodemographic covariates. RESULTS: In each of the two waves, three latent classes of drug use were identified among the students, defining three different groups of individuals: (1) abstainers/low users, (2) alcohol users/binge drinkers, and (3) polydrug users. First, parenting style (especially monitoring) was the strongest predictor for the prevention of polydrug use among adolescents. Second, occasional alcohol use by parents can act as a central predictor for adolescent alcohol use and binge drinking. Above all, maternal episodes of drunkenness were involved in the predictive models for both drug use classes in both waves. CONCLUSION: Parental alcohol use and parenting style seem to be important predictors of adolescent's likelihood of belonging to different latent classes of drug use. This conclusion may point to the importance of considering the inclusion of parenting skills and parental alcohol use within the scope of adolescents' preventive interventions.

A randomized controlled trial was conducted with 6637 7th- and 8th-grade students in 72 public schools in 6 Brazilian cities to evaluate the effects of the European drug prevention program Unplugged, called #Tamojunto in Brazil. This article evaluates the effects of #Tamojunto on the prevention of bullying and physical violence. Baseline data were collected from both intervention and control groups prior to program implementation. Follow-up data collection was performed 9 and 21 months later. Generalized estimating equations were used to evaluate changes in the reporting of receiving or practicing bullying and physical violence over time. The program was found to reduce the likelihood of receiving bullying, particularly in the stratum of girls aged 13-15 years at the 9-month follow-up time point. The effect was not sustained at 21 months. There was no significant effect for practicing bullying and for receiving or practicing physical violence.

A randomized controlled trial was conducted in 2014 with 7th and 8th grade students from 72 public schools in 6 Brazilian cities. This trial aimed to evaluate the effects of an adapted European school-based drug prevention program Unplugged, called #Tamojunto in Brazil, which was implemented by the Ministry of Health as part of public policy. The experimental group (n = 3340) attended 12 classes in the #Tamojunto program, and the control group (n = 3318) did not receive a school prevention program. Baseline data were collected prior to program implementation, and follow-up data were collected 9 months later, allowing a matching of 4213 adolescents in both waves. The substances examined were alcohol, tobacco, marijuana, inhalants, cocaine, and crack. Multilevel analyses were used to evaluate the changes in consumption of each drug between time points and between groups. The intervention and control groups had similar baseline characteristics. The mean age of the adolescents was 12.5 ± 0.7 years, and 51.3% were female. The program seemed to increase alcohol use initiation (first alcohol use); students in the experimental group had a 30% increased risk of initiating alcohol use during the 9-month follow-up (aRR = 1.30, 95% confidence interval (95%CI) 1.13-1.49, p < 0.001) compared to the control group. The opposite was found for the first inhalant use: the risk of using inhalants for the first time after baseline was lower in the experimental group (aRR = 0.78, 95%CI 0.63-0.96, p = 0.021) than the control group. The results of the #Tamojunto program suggest that the content and lessons regarding alcohol may enhance curiosity about its use among adolescents. We suggest a re-evaluation of the expansion of the #Tamojunto program in schools while analyzing why the program's effects were inconsistent with those of previous European studies.

OBJECTIVE: To describe the changes in alcohol and drug use by Brazilian adolescents during the COVID-19 pandemic (April-August 2021), and to analyze the relationship between alcohol use changes and psychiatric symptomatology. METHODS: A secondary analysis with a longitudinal approach was performed with data from a cluster-randomized controlled trial, conducted in 73 public middle schools in three Brazilian cities, to evaluate the effectiveness of a drug use prevention program. The sample included 535 students (61% girls; Mage = 15.2 years). Data were collected pre-intervention (February-March 2019), after 9 months (November-December 2019), and after 26 months (April-August 2021), when the students were in their first year of high school. The authors analyzed drug use prevalence (alcohol, binge drinking, tobacco, inhalants, marijuana, cocaine, and crack) in a lifetime, past year, and past month periods, and the association between alcohol use change subsamples with psychiatric symptoms. Logistic regressions were adjusted by sex, age, socioeconomic status, city, and group (control and intervention). RESULTS: The present findings suggest that the COVID-19 pandemic led to a decrease in past-year substance use and in past-month substance use frequency, despite the gradually increased (but decelerating) prevalence of lifetime use. However, some adolescents initiated, maintained, or increased the frequency of their alcohol use. Mainly, they were more likely to present behavioral problems, as well as symptoms of inattentive hyperactivity, and peer and emotional problems. CONCLUSIONS: Despite the extensive decline in substance use during the pandemic period, these results suggest an association between previous mental health conditions and behavioral risk factors, leading to increased alcohol consumption and behavioral disorders manifestations.

INTRODUCTION: This study reports the evaluation of the short-term effects of the Strengthening Families Program (SFP 10-14), adapted as Famílias Fortes (Strong Families) in Brazil, on preventing adolescent drug use and improving parenting behaviors. METHODS: A two-arm, parallel cluster randomized controlled trial was conducted in 60 Social Assistance Reference Centers (SARC) from 12 Brazilian municipalities. In each city, the SARC were randomly assigned to the intervention or control group. A total of 805 families participated in the study, each contributing data from one parent or legal guardian and one adolescent totaling 1,610 participants. Data collection occurred before intervention implementation and 6 months after baseline collection. Data were analyzed using multilevel mixed-effects modeling with repeated measures in two different paradigms: Intention to Treat (ITT) and Per protocol (PP). The study was registered in the Brazilian Ministry of Health Register of Clinical Trials (REBEC), under protocol no. RBR-5hz9g6z. RESULTS: Considering the ITT paradigm, the program reduced the chance of parents and legal guardians being classified as negligent by 60% (95%CI 0.21; 0.78), increased the use of nonviolent discipline by caregivers (Coef 0.33, 95%CI 0.01; 0.64) and decreased the chance of adults exposing adolescents to their drunken episodes by 80% (95%CI 0.06; 0.54). No program effects were observed on outcomes related to adolescent drug use. Similar results were found for the PP paradigm. CONCLUSION: The positive effects on family outcomes suggest preventive potential of the program among the Brazilian population. Long-term evaluations are necessary to verify if the program can also achieve the drug use reduction goals not observed in the short term.
RESUMEN
OBJECTIVE: To investigate the mechanisms of the #Tamojunto2.0 program that mediated the prevention of lifetime alcohol and drug use, including drug knowledge, behavioral beliefs, attitudes, decision-making skills, and refusal skills. METHODS: A cluster-randomized controlled trial was conducted in 73 public middle schools in three Brazilian cities. The sample included 5208 students (49.4 % girls; Mage = 13.2 years). The intervention group attended twelve #Tamojunto2.0 lessons conducted by their previously trained teachers. The control group did not receive any intervention. Data were collected pre-intervention and at the 9-months follow-up. We performed multiple mediation models (for the whole sample, users, and non-users) with a post-estimation adjustment to standard errors to account for nesting. We analyzed all available mediators simultaneously according to each drug: alcohol, binge drinking, tobacco, marijuana, and inhalant lifetime use. To handle missing data, we used the "full-information maximum-likelihood" paradigm. RESULTS: Outcomes in the whole sample and among non-users showed that #Tamojunto2.0 indirectly prevented lifetime alcohol use and binge drinking by increasing negative and non-positive alcohol beliefs. Only the direct effect on decreasing lifetime alcohol consumption was statistically significant. However, an indirect increase in binge drinking was observed through knowledge about alcohol, but the direct effect was not statistically significant. No effects were reported for marijuana, tobacco, or inhalants. Among users, no statistically significant effects were found for alcohol or drug use. CONCLUSIONS: The results suggest that the #Tamojunto2.0 program was only effective in delaying alcohol consumption via increasing negative and non-positive alcohol beliefs. It seems that mediating mechanisms vary depending on contextual characteristics, differences in socializing among adolescents, features of the educational systems, psychosocial conditions, or, fidelity issues of program implementation.

This study aimed to estimate the prevalence of binge drinking and other alcohol consumption patterns and analyze the sociodemographic characteristics associated with binge drinking among Brazilian adolescents aged 15 to 17 years. A cross-sectional household survey including 2,315 adolescents from the 2019 Brazilian National Health Survey who answered a questionnaire on alcohol consumption (weekly frequency, average amount consumed in a drinking day, and binge drinking). A descriptive analysis of alcohol consumption by sociodemographic characteristics and a multivariable logistic regression model were performed. The prevalence of binge drinking (past 30 days) was 8.1% (95%CI: 6.2-10.3). Adolescents who did not attend school (OR = 2.8; 95%CI: 1.6-5.0) had greater odds of binge drinking than adolescents attending school. Higher socioeconomic status (measured via wealth score) was also associated with higher odds of binge drinking compared with lower socioeconomic status (e.g., 5th quintile vs. 1st quintile: OR = 2.9; 95%CI: 1.1-7.7). Girls had lower odds of binge drinking (OR = 0.5; 95%CI: 0.2-0.8) than boys. The prevalence of binge drinking among adolescents, especially boys, who did not attend school and had higher socioeconomic status was high. Monitoring alcohol consumption patterns in adolescents may provide important information on policies or actions to prevent binge drinking.

BACKGROUND: "Open bar" parties are events where a flat fee is paid for unlimited alcohol consumption. At these events, alcohol intoxication is frequent amongst attendees. This study explored the prevalence of "open bar" attendance amongst Brazilian youth and the factors associated with this practice. METHODS: Data was collected at the baseline of randomized controlled trial amongst 5,213 8th grade students in three Brazilian cities. Weighted logistic regression was performed. RESULTS: Mean age was of 13.23 years (SE 0.01) and 17.1% of the students have reported attending "open bar" events in the past year. Attendees were wealthier, had higher odds to engage in binge drinking, to use marijuana, to be exposed to alcohol advertising, and to report more alcohol problems and clinical psychiatric symptoms when compared with non-attendees. CONCLUSIONS: The ban on selling alcohol to minors has not been properly enforced. Legislation to restrict alcohol promotions and advertising in Brazil needs to be implemented and effectively monitored.

PURPOSE: The Brazilian version of the prevention program Unplugged, #Tamojunto, has had a positive effect on bullying prevention. However, the curriculum has recently been revised, owing to its negative effects on alcohol outcomes. This study evaluated the effect of the new version, #Tamojunto2.0, on bullying. For adolescents exposed to the school-based program #Tamojunto2.0, we investigated (1) whether the prevalence of bullying victimization and perpetration was reduced, (2) whether this reduction was moderated by gender, and (3) whether the program's effect on bullying was mediated by adolescents' alcohol use. METHODS: A cluster randomized controlled trial was conducted using 5,208 eighth-grade students from 73 Brazilian public schools. Baseline data were collected before program implementation, and follow-up data were collected nine months later. We used a multilevel mixed-effects model to examine the effect of #Tamojunto2.0 on bullying, and a moderation model to test the moderating effect of gender on program outcomes. A mediation analysis was performed to determine lifetime alcohol use as a mediator of the intervention effect on bullying. RESULTS: We found that the positive effect of #Tamojunto2.0 on bullying victimization (ß = -0.019, 95% confidence interval = -0.035; -0.002) and perpetration (ß = -0.027, 95% confidence interval = -0.051; -0.004) was mediated by a decrease in alcohol use, but not moderated by gender. DISCUSSION: #Tamojunto2.0 program can be indirectly effective in the prevention of bullying by decreasing adolescents' alcohol use. Moreover, alcohol and drug use prevention programs might also affect bullying outcomes through mediation, and we suggest that future studies consider this.
