RESUMO

BACKGROUND: The rising prevalence of electronic cigarette (e-cigarette) and hookah use among youth raises questions about medical trainees' views of these products. We aimed to investigate medical trainees' knowledge and attitudes toward e-cigarette and hookah use. METHODS: We used data from a large cross-sectional survey of medical trainees in Brazil, the United States, and India. We investigated demographic and mental health aspects, history of e-cigarettes and tobacco use, knowledge and attitudes toward e-cigarettes and hookah, and sources of information on e-cigarettes and hookah. Although all medical trainees were eligible for the original study, only senior students and physicians-in-training were included in the present analysis. RESULTS: Of 2,036 senior students and physicians-in-training, 27.4% believed e-cigarette use to be less harmful than tobacco smoking. As for hookah use, 14.9% believed it posed a lower risk than cigarettes. More than a third of trainees did not acknowledge the risks of passive e-cigarette use (42.9%) or hookah smoking (35.1%). Also, 32.4% endorsed e-cigarettes to quit smoking, whereas 22.5% felt ill equipped to discuss these tobacco products with patients. Fewer than half recalled attending lectures on these topics, and their most common sources of information were social media (54.5%), Google (40.8%), and friends and relatives (40.3%). CONCLUSIONS: Medical trainees often reported incorrect or biased perceptions of e-cigarettes and hookah, resorted to unreliable sources of information, and lacked the confidence to discuss the topic with patients. An expanded curriculum emphasis on e-cigarette and hookah use might be necessary because failing to address these educational gaps could risk years of efforts against smoking normalization.

RESUMO

Objectives: To examine drug overdose records in Brazil from 2000 to 2020, analyzing trends over time in overdoses and overall sociodemographic characteristics of the deceased. Methods: Using data from the Brazilian Mortality Information System (Sistema de Informações sobre Mortalidade), we identified records from 2000-2020 in which the underlying cause-of-death was one of the following codes: X40-X45 (accidental poisoning), X60-X65 (intentional poisoning), or Y10-Y15 (undetermined intentionality poisoning). The Brazilian dataset included 21,410 deaths. We used joinpoint regression analysis to assess changes in trends over time. Results: People who died of drug overdoses in Brazil between 2000 and 2020 had a mean age of 38.91 years; 38.45% were women, and 44.01% were identified as White. Of the overdose deaths, 44.70% were classified as intentional and 32.12% were classified as unintentional. Among the identified drugs, stimulants were the most common class. However, most records did not report which drug was responsible for death. Conclusion: Sociodemographic trends in overdose deaths in Brazil must guide country-specific policies. Nevertheless, data collection protocols must be improved, particularly regarding the drug used in overdoses.

RESUMO

The increased use of E-cigarettes and hookah among young consumers represents a public health concern. This study aimed to investigate the frequency and patterns of use of E-cigarettes and hookah among medical trainees. This cross-sectional multinational online survey included medical students, residents, and fellows in Brazil, the U.S., and India between October 2020 and November 2021. Information on sociodemographics; mental health; and E-cigarettes, hookah, tobacco, marijuana, and alcohol use were collected. Generalized structural equation models were used in 2022 to explore the factors associated with current vaping and current hookah use (ongoing monthly/weekly/daily use). People reporting previous sporadic/frequent use or those who never used/only tried it once were the reference group. Overall, 7,526 participants were recruited (Brazil=3,093; U.S.=3,067; India=1,366). The frequency of current vaping was 20% (Brazil), 11% (U.S.), and <1% (India), and current hookah use was 10% (Brazil), 6% (U.S.), and 1% (India). Higher family income (OR=6.35, 95% CI=4.42, 9.12), smoking cigarettes (OR=5.88, 95% CI=4.88, 7.09) and marijuana (OR=2.8, 95% CI=2.35, 3.34), and binge drinking (OR=3.03, 95% CI=2.56, 3.59) were associated with current vaping. The same was true for hookah use: higher family income (OR=2.69, 95% CI=1.75, 4.14), smoking cigarettes (OR=3.20, 95% CI=2.53, 4.06), smoking marijuana (OR=4.17, 95% CI=3.35, 4.19), and binge drinking (OR=2.42, 95% CI=1.96, 2.99). In conclusion, E-cigarettes and hookah were frequently used by Brazilian and American trainees, sharply contrasting with data from India. Cultural aspects and public health policies may explain the differences among countries. Addressing the problems of hookah and E-cigarette smoking in this population is relevant to avoid the renormalization of smoking.

RESUMO

Objective To investigate factors associated with violent behavior in a large nationally representative sample of Brazilian adolescents. Methods The data were derived from the 2015 National Adolescent School-based Health Survey (Pesquisa Nacional de Saúde do Escolar [PeNSE]). The independent variables of interest included feelings of safety while on the way to and at school. The outcome was violent behavior, including bullying. Logistic regression models were developed to examine the relationship between violent behavior and each independent and control variable. Results In the adjusted regression model, male sex (aOR: 1.75; 95%CI 1.65-1.86), being assaulted by a family member (aOR: 1.74; 95%CI 1.59-1.90), and being assaulted in the past year (aOR: 1.70; 95%CI 1.57-1.85) all increased the chance of violent behavior. Feeling safe on the way to school (aOR: 0.82; 95%CI 0.74-0.92) and at school (aOR: 0.82; 95%CI 0.73-0.92) reduced the chance of violent behavior. Conclusion This study extends the body of literature on violent behavior among adolescents, demonstrating a correlation between school, domestic, family, or community violence and violent behavior. Our research supports the idea that adolescents who experience violence act violently with greater frequency. This finding has significant implications for pediatricians, child psychiatrists and psychologists, other health care professionals, school professionals, and other professionals involved in adolescent health. School professionals must be prepared to identify adolescents with violent behavior due to its potential consequences for their mental and physical health.

RESUMO

Tobacco use is associated with an annual global economic cost of two trillion dollars and mortality of half of its regular users. Tobacco leaf cultivation is the starting point of the tobacco cycle. Tobacco farming employs millions of small-scale tobacco farmers around the globe, most of whom are out growers who rely on the tobacco industry. This paper aims to map the regions of greatest tobacco production globally (i.e., the US, Brazil, China, Indonesia, India, and Zambia) and tobacco use rates in these locations. Smoking rates were higher in those areas, except for India, where important population subgroups reported an upward trend for tobacco smoking. In general, there was a relationship between tobacco farming and tobacco smoking. Tobacco farming may lead to a higher risk of tobacco use and lower adherence to tobacco control policies. Therefore, promoting viable alternative livelihoods for tobacco farmers must have dual benefits. Additionally, specific health prevention policies might be necessary for those populations reporting higher tobacco use and lower perception of tobacco-related health risks.

RESUMO

Objective: To review the literature regarding adolescent suicide risk and explore the associations between treatment compliance (expressed as a concept including measured adherence to treatment and/or mental health service utilization) and risk and protective factors for suicidal behavior (SB), as well as the association between treatment compliance and reattempts. Methods: PubMed, LILACS, and Google Scholar were searched using the following terms: (adolescent*) AND (suicide*) AND (risk factor OR protective factors) AND (treatment compliance OR treatment attrition OR treatment adherence OR treatment drop out OR treatment retention OR mental health utilization). We retrieved studies that focused on the relation of treatment compliance to risk and protective factors for SB and that had only adolescent samples. Results: Of 4,841 articles, 30 original articles were selected for review. Most studies indicated high mental health service (MHS) utilization and poor treatment adherence by SB patients. Social minority status and conduct disorder were associated with less treatment adherence, while female sex, parental perceived need for treatment, and major depression were associated with greater treatment adherence. Inpatient and intensive emergency care after SA and family interventions improved MHS utilization and treatment compliance. However, we found no substantial protective effect of treatment compliance against reattempts. Conclusion: Effective treatment planning for compliance requires considering psychopathology, treatment planning, and social, familial, and individual factors.

RESUMO

This article continues our presentation of the Brazilian Psychiatric Association guidelines for the management of patients with suicidal behavior, with a focus on screening, intervention, postvention, prevention, and promotion. For the development of these guidelines, we conducted a systematic review of the MEDLINE (via PubMed), Cochrane Database of Systematic Reviews, Web of Science, and SciELO databases for research published from 1997 to 2020. Systematic reviews, clinical trials, and cohort/observational studies on screening, intervention, and prevention in suicidal behavior were included. This project involved 14 Brazilian psychiatry professionals and 1 psychologist selected by the Psychiatric Emergencies Committee of the Brazilian Psychiatric Association for their experience and knowledge in psychiatry and psychiatric emergencies. Publications were evaluated according to the 2011 Oxford Center for Evidence-Based Medicine (OCEBM) Levels of Evidence Classification. Eighty-five articles were reviewed (of 5,362 initially collected and 755 abstracts on the drug approach). Forms of screening, intervention, and prevention are presented. The intervention section presents evidence for psychotherapeutic and drug interventions. For the latter, it is important to remember that each medication is effective only for specific groups and should not replace treatment protocols. We maintain our recommendation for the use of universal screening plus intervention. Although the various studies differ in terms of the populations evaluated and several proposals are presented, there is already significant evidence for certain interventions. Suicidal behavior can be analyzed by evidence-based medicine protocols. Currently, the best strategy is to combine several techniques through the Safety Plan. Nevertheless, further research on the topic is needed to elucidate some approaches with particular potential for intervention and prevention. Systematic review registry number: CRD42020206517

RESUMO

Bullying and substance use are serious public health concerns. The aim of this article is to review empirical studies that examined the association between bullying perpetration and substance use among adolescence in various countries. Research studies that found a correlation between bullying perpetration and substance use in children and adolescents were reviewed. From the search, 7,844 abstracts were identified and 7,795 were excluded. Fifty-four remaining articles were reviewed, and 23 were excluded after full text review. A total of 31 articles, which all met the inclusion criteria, were considered in the review. Findings from the review suggest that children who engaged in bullying are more likely to be involved in alcohol, tobacco, and illicit drug use. Substance use prevention efforts require an examination of peer dynamics and peer relationships. In addition, bullying and substance use prevention require family dynamics and how they may increase the risk of bullying and drugs abuse.

RESUMO

Objective: To explore the contribution of a mindfulness-based intervention as an adjuvant to outpatient substance use disorder treatment. Outcomes included substance use behavior, depression and anxiety symptoms, and anger expression. Methods: This preliminary study for a pragmatic randomized controlled trial with stratified random allocation included three months of follow-up. In two outpatient clinics linked to public universities, a mindfulness-based intervention plus treatment as usual (experimental group n=22) was compared to treatment as usual (control group n=20). The study included data from self-report measurements and the patients' records, which were evaluated according to intention-to-treat analysis through generalized estimating equations and generalized method of moments estimation. Results: The experimental group had lower symptoms of depression (b=-6.82; 95%CI -12.45 to -1.18) and anxiety (b=-0.25; 95%CI -0.42 to -0.09), and anger expression (b=-9.76; 95%CI -18.98 to -0.54) three months after the intervention. We detected no effect on substance use behavior. Conclusion: The mindfulness-based intervention yielded promising results as an adjuvant to outpatient substance use disorder treatment, since it reduced levels of highly prevalent symptoms in this population. However, further studies with longer follow-up periods and larger samples are required.

RESUMO

RATIONALE: Agonist-based pharmacologic intervention is an accepted approach in treatment of opioid and tobacco use disorders. OBJECTIVES: We conducted a systematic review and meta-analysis to evaluate usefulness of an agonist approach as treatment of (psycho)stimulant use disorder (PSUD). METHODS: We reviewed PubMed/Medline, LILACS, and ClinicalTrials.gov databases searching for randomized, double-blind, placebo-controlled, parallel-design studies evaluating outcomes of individuals treated for cocaine- or amphetamine-type substance use disorder. We combined results of all trials that included the following prescription psychostimulants (PPs): modafinil, methylphenidate, or amphetamines (mixed amphetamine salts, lisdexamphetamine, and dextroamphetamine). The combined sample consisted of 2889 patients. Outcomes of interest included the following: drug abstinence (defined as 2-3 weeks of sustained abstinence and the average maximum days of consecutive abstinence), percentage of drug-negative urine tests across trial, and retention in treatment. We conducted random-effects meta-analyses and assessed quality of evidence using the GRADE system. RESULTS: Thirty-eight trials were included. Treatment with PPs increases rates of sustained abstinence [risk ratio (RR) = 1.45, 95% confidence interval (CI) = (1.10, 1.92)] and duration of abstinence [mean difference (MD) = 3.34, 95% CI = (1.06, 5.62)] in patients with PSUD, particularly those with cocaine use disorder (very low-quality evidence). Prescription amphetamines were particularly efficacious in promoting sustained abstinence in patients with cocaine use disorder [RR = 2.44, 95% CI = (1.66, 3.58)], and higher doses of PPs were particularly efficacious for treatment of cocaine use disorder [RR = 1.95, 95% CI = (1.38, 2.77)] (moderate-quality evidence). Treatment with prescription amphetamines also yielded more cocaine-negative urines [MD = 8.37%, 95% CI = (3.75, 12.98)]. There was no effect of PPs on the retention in treatment. CONCLUSION: Prescription psychostimulants, particularly prescription amphetamines given in robust doses, have a clinically significant beneficial effect to promote abstinence in the treatment of individuals with PSUD, specifically the population with cocaine use disorder.

RESUMO

BACKGROUND: Barriers to early childhood development (ECD) are a global concern. Limited research exists on prenatal smoking and ECD in vulnerable populations, especially as it relates to school readiness (SR). AIMS: To examine how maternal cigarette use during pregnancy is associated with SR in a sample of Brazilian preschool-age children. STUDY DESIGN: We used the Brazilian Preschool Mental Health Study, a cross-sectional, epidemiological study of preschool-age children in Embu das Artes, São Paulo. SR was assessed using the Engle Scale of Child Development (ESCD). We restricted analyses to biological mothers, who represented 81.9% (n = 591) of the total 722 with ESCD data. Logistic regression models, adjusting for birth and child characteristics (year of preschool, sex, race, history of head trauma, coma, convulsions or epilepsy), sociodemographic factors and school environment, were used to estimate odds ratios and 95% confidence intervals. RESULTS: Prenatal smoking was negatively associated with SR. Children of mothers who smoked during pregnancy were more likely to be in the lowest ESCD quartile (aOR = 1.26, 95%CI: [1.02-1.55]) compared to those of non-smoking mothers, and each cigarette resulted in additional risk (aOR = 1.03, 95%CI:[1.01-1.05]). Children of heavy smokers had worse ESCD scores compared to children of non-smokers (aOR = 1.69, 95%CI:[1.18-2.44]), as well as when compared to children of moderate and non-smokers combined (aOR = 1.77, 95%CI:[1.22-2.57]). This relationship was not seen when comparing children of moderate smokers to children of non-smokers. Inferences were robust when examining very heavy smoking. CONCLUSION: Maternal tobacco use during pregnancy may affect child SR. Additional studies in other populations are needed to corroborate these results.

RESUMO

Objective: Adolescent substance abuse is a public health concern worldwide, and its prevention is the subject of numerous programmatic efforts. Yet, little research exists on the structure of drug-related belief patterns in youth and their utility in preventive program planning. The aim of this study is to determine the structure of drug-related beliefs among 12-15-year-old students in Brazil using latent class analysis. Methods: De-identified survey data were obtained from the baseline sample (n=6,176) of a randomized controlled trial on the #Tamojunto drug use prevention program in Brazilian middle schools. Using 11 survey items assessing drug-related beliefs as indicators, four models were run and assessed for goodness-of-fit. For the best fitting model, demographic variables and substance use across latent classes were assessed. Results: Model fit statistics indicated that the best fit was a three-class solution, comprising a large Drug-Averse Beliefs class (80.9%), a smaller Permissive Beliefs class (12.7%), and an Inconsistent Beliefs class (6.4%). Respondents in the Permissive Beliefs and Inconsistent Beliefs classes reported greater past-year drug use, were slightly older and less likely to be female than those in the Drug-Averse Beliefs class. Conclusions: These results indicate that conceptualizing drug beliefs as a categorical latent variable may be useful for informing prevention. Longitudinal studies are needed to establish temporality and assess further applicability of this construct.

RESUMO

Objective: We examined the sociodemographic factors associated with smoking risk perceptions (SRP) in youth living in two very different neighborhoods in the city of São Paulo, Brazil: a middle-class central area (Vila Mariana) and a poor outer-city area (Capão Redondo). Methods: A cross-sectional survey was conducted with 180 public school-attending youth (all aged 12 years) and their parents. SRP was evaluated through self-reports. Weighted multinomial logistic regression was used to examine factors associated with SRP. Results: Smoking was considered a high-risk behavior by 70.9% of adolescents. There were significant differences in SRP associated with socioeconomic status (SES) and maternal smoking status. Having a non-smoking mother was positively associated with perceiving smoking as having low to moderate risk versus no risk (OR=3.91 [95%CI 1.27-12.02]). Attending school in Capão Redondo was associated with perceiving smoking as having high risk compared to no risk (OR=3.00 [95%CI 1.11-8.12]), and low SES was negatively associated with perceiving at least some risk in smoking versus perceiving no risk in this behavior. Conclusions: Youth whose mothers smoke appear to have lower SRP than those whose mothers do not smoke. Living in a poor outer-city area was associated with higher SRP.
