Os jovens seguem usando narguilé apesar do conhecimento dos possíveis riscos à saúde / Young people continue to use hookah despite knowledge of possible health risks

É preocupante notar que os usuários sigam usando o narguilé, embora a literatura aponte que o seu uso cause danos irreversíveis à saúde. Esse estudo avaliou a percepção dos usuários de narguilé e a interferência do seu consumo sobre a saúde. Método Esse é um estudo qualitativo. Uma amostra intencional de usuários foi recrutada. Os participantes responderam a uma entrevista semiestruturada. Todas as entrevistas foram avaliadas pelo método de análise de conteúdo. Resultados A maioria dos discursos apontou que os entrevistados conhecem os malefícios à saúde advindos do uso de narguilé. Entretanto, os efeitos sobre a saúde mental raramente foram lembrados pelos entrevistados, embora muitos deles já estivessem em uso problemático de tabaco, álcool e ou de outras drogas. A percepção de controle sobre o uso, o poder reforçador dos efeitos e a ausência de experiências pessoais negativas com o narguilé são importantes motivadores para seguir o uso. Conclusão Campanhas educativas e medidas para a redução e o controle do uso devem ser encorajadas.

Although the scientific literature show that waterpipe tobacco smoking causes irreversible damage to health, users continue to use it. Method This study evaluates the users' perceptions about the effect of this consumption on health. This is a qualitative study. A purposeful sample of current users was recruited. Participants were invited to undertake an in-depth semi-structured interview. The interviews were evaluated by content analysis method. Results Most speeches pointed out that the interviewees are aware of the harm to health from using waterpipe tobacco smoking. Although most interviewees were already developing a problematic use of tobacco, alcohol or other drugs, they rarely related waterpipe tobacco smoking with mental health consequences. The essential motivators for its continued use were the perception of control over waterpipe tobacco smoking use, the reinforcing tobacco effects, and the absence of negative health experiences in life. Conclusion Understand that educational campaigns and control measures should be encouraged.

Sex differences in smoking cessation: a retrospective cohort study in a psychosocial care unit in Brazil

Abstract Introduction Despite the results of epidemiological and psychometric studies reporting comparable levels of tobacco dependence among males and females, some clinical studies have detected disparities. Some smoking cessation studies based on clinical setting programs reported poorer outcomes among women than men. Methods This retrospective cohort study aimed to compare treatment success and retention between men and women on a smoking cessation program (n = 1,014) delivered at a CAPS-AD unit in Brazil. The psychological intervention lasted 6 weeks for each group of 15 patients. Each patient had to participate in weekly group cognitive-behavioral therapy (CBT) sessions and individual medical appointments during this period. These appointments were focused on the possibility of prescribing pharmacological treatment (i.e., nicotine replacement therapy, bupropion, or nortriptyline) as adjuvants to group therapy. Results The women had lower smoking severity at baseline, more clinical symptoms, and lower prevalence of alcohol and drug use disorders and were older than the men. Females had significantly higher levels of success (36.6% vs. 29.7%) and retention (51.6% vs. 41.4%) than males. Sensitivity analysis showed that female gender was significantly associated with both retention and success, among those without drug use disorders only. Conclusion Depending on the smoking cessation setting (i.e., low and middle-income countries and mental health and addiction care units), females can achieve similar and even higher quit rates than males. Previous drug use disorder was an important confounding variable in the gender outcomes analyses. Future studies should try to replicate these positive smoking cessation effects of CBT-based group therapy plus pharmacotherapy in women.

Abstinence and retention outcomes in a smoking cessation program among individuals with co-morbid substance use and mental disorders.

Tobacco use is the leading cause of preventable death in the world. Although cigarette smoking prevalence has decreased, there are still disparities in morbidity and mortality experienced by individuals with substance use and/or mental disorders when compared to general population. The aim of this study was to compare treatment outcomes between three subgroups of smokers: individuals with substance use disorder (SUD-only), individuals with mental disorder without substance use disorders (MD-only), and individuals with co-morbid substance use and mental disorder (SUD + MD). Data of 498 smokers enrolled in a 6-week smoking cessation program in Brazil were analyzed. Sociodemographic, medical and tobacco use information were collected at baseline. Treatment included group cognitive behavioral therapy (CBT) and pharmacotherapy. The primary outcome was defined as "self-report 4-week quitter" (SR4WQ), a standardized measure to assess treatment success. Retention to treatment was also investigated. Associations between groups were analyzed using unadjusted and adjusted logistic regression models. The results showed that SUD + MD had worse outcomes when compared to the other two groups. After adjusting for level of smoking dependence and the use of medication, abstinence and retention to treatment of SUD-only became equivalent to SUD + MD. Because tobacco and other substance addictions share similar mechanisms, having history of SUD might impair successful results of conventional smoking programs. There is a need to further investigate specific variables associated with treatment success for a more resistant subgroup of individuals in mental health and perhaps to invest in more intensive actions, such as the use of combined pharmacotherapy and adapted CBT approaches.

Distinct effects of cocaine and cocaine + cannabis on neurocognitive functioning and abstinence: A six-month follow-up study.

BACKGROUND AND AIMS: Cannabis use is frequent among individuals with cocaine use disorder. Despite recent non-controlled studies advocating a therapeutic role of smoked cannabis, there is a paucity of evidence-based data on potential therapeutic and cognitive side-effects of this association. METHODS: We examined 63 cocaine-addicted subjects who used cannabis more than 50 times in lifetime (COC + CAN), 24 cocaine-addicted patients who use cannabis less than 50 times (COC), and 36 controls (CON). Participants were evaluated with an extensive battery of neurocognitive tests after two weeks of supervised detoxification in an inpatient treatment program. Patients were followed up in one, three, and six months after discharge. RESULTS: Both groups of patients performed worse than CON on working memory, processing speed, inhibitory control, mental flexibility, and decision making. COC + CAN performed worse than COC on speed processing, inhibitory control and sustained attention, while COC performed worse than COC + CAN on mental flexibility. Concomitant cannabis use did not decrease relapses to cocaine use after one, three and six months. Among COC + CAN, earlier cocaine and cannabis use, and impaired executive functioning were predictive of relapse on cocaine after six months. CONCLUSION: Our results did not support the recommendation of smoked cannabis as a safe therapeutic approach for cocaine-addicted patients due to significant negative cognitive side-effects and absence of efficacy. Further studies investigating frontal brain morphology, neuromaturation, and prescription of the non-psychoactive constituent of cannabis sativa cannabidiol among cocaine-addicted patients who use cannabis are warranted.

Experimentation with tobacco during adolescence as a factor influencing treatment of smoking in adulthood. A retrospective cohort.

BACKGROUND: There are still few studies on predictors of smoking cessation in Brazilian samples. Experimentation with tobacco during adolescence (ETA) may be one of the important predictors. OBJECTIVE: This study aimed, within the context of a treatment-seeking group of subjects, to test the hypothesis that ETA negatively affects the outcome of smoking cessation during adulthood. DESIGN AND SETTING: Retrospective (historic) cohort study conducted at a psychosocial care center in São Paulo, Brazil, between 2007 and 2010. METHODS: Data on sociodemographics, smoking and medical profiles were obtained through self-report questionnaires that were completed at the baseline and at any follow-up appointment. Logistic regression models were constructed to describe factors associated with the outcome of smoking cessation, measured according to the self-reported four-week success rate among 367 outpatient smokers. RESULTS: ETA was found to be associated with not quitting smoking through the treatment (odds ratio = 0.57; 95% confidence interval = 0.33-0.96; P < 0.05), even after adjustment for dependence level, sociodemographics, nicotine patch use and number of years of smoking. CONCLUSIONS: Early exposure to nicotine may lead to higher risk of continuing smoking after treatment, in adulthood.

Smoking cessation treatment outcomes among people with and without mental and substance use disorders: An observational real-world study.

BACKGROUND: There is a lack of studies evaluating smoking cessation treatment protocols which include people with and without mental and substance use disorders (MSUD), and which allows for individuals with MSUD undergoing their psychiatric treatment. METHODS: We compared treatment success between participants with (n = 277) and without (n = 419) MSUD among patients in a 6-week treatment provided by a Brazilian Psychosocial Care Center (CAPS) from 2007 to 2013. Sociodemographic, medical and tobacco use characteristics were assessed at baseline. Tobacco treatment consisted of 1) group cognitive behavior therapy, which included people with and without MSUD in the same groups, and 2) pharmacotherapy, which could include either nicotine patches, nicotine gum, bupropion or nortriptyline. For participants with MSUD, tobacco treatment was integrated into their ongoing mental health treatment. The main outcome was 30-day point prevalence abstinence, measured at last day of treatment. RESULTS: Abstinence rates did not differ significantly between participants with and without MSUD (31.1% and 34.4%, respectively). Variables that were significantly associated with treatment success included years smoking, the Heaviness of Smoking Index, and use of nicotine patch or bupropion. CONCLUSION: The inclusion of individuals with and without MSUD in the same protocol, allowing for individuals with MSUD undergoing their psychiatric treatment, generates at least comparable success rates between the groups. Predictors of treatment success were similar to those found in the general population. Facilities that treat patients with MSUD should treat tobacco use in order to reduce the disparities in morbidity and mortality experienced by this population.

Smoking Cessation Treatment for Patients With Mental Disorders Using CBT and Combined Pharmacotherapy.

OBJECTIVES: The aim of this study was to investigate smoking treatment effectiveness and retention in a population with and without mental disorders (MD). Participants received cognitive behavioral therapy (CBT) plus nicotine patch alone or in combination with other medications (i.e., gum, bupropion, or nortriptyline) for smoking cessation treatment in a Brazilian Psychosocial Care Center unit (CAPS), taking into account sociodemographics and smoking profile covariates. METHODS: The study involved comparison of treatment success (seven-day point prevalence abstinence at the end of the treatment) and retention (presence of the individual in all of the four medical consultations and six group sessions) in two subsamples of patients with MD (n = 267) and without MD (n = 397) who were included in a six-week treatment provided by a CAPS from 2007 to 2013. The treatment protocol comprised group CBT and pharmacotherapy (nicotine patches, nicotine gums, and bupropion and nortriptyline available, prescribed by psychiatrists). RESULTS: Within patients with MD, CBT plus nicotine patch plus bupropion (aOR = 2.00, 95% CI [1.14, 3.50], p = .015) and CBT plus nicotine patch plus gum (aOR = 2.10, 95% CI [1.04, 4.23], p = .036) were associated with treatment success. Within patients without MD, female gender (aOR = 0.60, 95% CI [0.37, 0.95], p = .031) and lower Heaviness of Smoking Index score (aOR = 0.80, 95% CI [0.65, 0.99], p = .048) were associated with treatment success. No variable was associated with dropout or retention within patients with or without MD. CONCLUSION: Our findings support the use of CBT plus nicotine patch plus bupropion as well as CBT plus nicotine patch plus gum in samples with high rates of medical, psychiatric, and addiction disorders. These findings support those of previous studies in the general population. Pharmacological treatment associated with group CBT based on cognitive-behavioral concepts and combined with ongoing MD treatment seems to be the best option for smoking cessation treatment among patients with MD. Units that deal with patients with MD, such as CAPS in Brazil, should be encouraged to treat smoking addiction in this population. Future studies should investigate retention rates in other samples of patients with MD.

Intention to Drive After Drinking Among Medical Students: Contributions of the Protection Motivation Theory.

OBJECTIVE: The aim of this study was to investigate whether cognitive variables proposed by the protection motivation theory (PMT) were predictive of occasional and frequent intention to drive after drinking in medical students. METHODS: One hundred fifty-five students attending preclinical years at a Medical School in São Paulo, Brazil, participated in the study. They were asked about their last month substance use, history of drinking and driving, including driving after binge drinking, and risk perceptions based on a self-report questionnaire with statements about protection motivation, threat, and coping appraisals from the PMT model. RESULTS: Fifty-two students (33%) had previous experience of driving after drinking during the last year, and 54 students (35%) reported intention to drive after drinking within the next year. Regression analysis showed that higher scores in perception of personal vulnerability to risks were associated with occasional and frequent intention to continue pursuing this particular behavior. Poorer evaluations about short-term consequences of alcohol consumption and cognitions regarding external rewards were significantly associated with reported intention to continue driving after drinking. CONCLUSIONS: Considering the social and health impact of alcohol-impaired behaviors, our findings suggest the need of interventional efforts focused in increasing students' awareness about the negative consequences of drinking and driving aiming to enhance their motivation towards more adaptive behaviors.

Outcome predictors of smoking cessation treatment provided by an addiction care unit between 2007 and 2010

Objective: To analyze the predictors of smoking cessation treatment outcomes in a sample with a high rate of medical and psychiatric disorders and addictions. Methods: Analysis of predictors of success of a 6-week treatment provided by an addiction care unit (CAPS-AD) to 367 smokers in Brazil from 2007 to 2010. Forty variables were collected at baseline. Success was defined as abstinence from smoking for a period of at least 14 consecutive days, including the last day of treatment. Twenty variables were selected for the logistic regression model. Results: The only condition correlated with successful treatment after logistic regression was smoking one's first cigarette 5 minutes or more after waking (beta = 1.85, 95% confidence interval [95%CI] = 1.11-3.10, p = 0.018). Subjects with hypertension and alcohol use disorders and those who were undergoing psychiatric treatment showed success rates comparable to or greater than the average success rate of the sample (34.2-44.4%). Conclusions: These findings support the importance of the variable time to first cigarette in treatment outcomes for a sample with a high rate of clinical and psychiatric disorders. Good success rates were observed for pharmacological treatment, which was combined with group therapy based on cognitive-behavioral concepts and integrated into ongoing treatment of other addictions and psychiatric disorders. .

Polydrug use among college students in Brazil: a nationwide survey.

OBJECTIVE: To estimate the frequency of polydrug use (alcohol and illicit drugs) among college students and its associations with gender and age group. METHODS: A nationwide sample of 12,544 college students was asked to complete a questionnaire on their use of drugs according to three time parameters (lifetime, past 12 months, and last 30 days). The co-use of drugs was investigated as concurrent polydrug use (CPU) and simultaneous polydrug use (SPU), a subcategory of CPU that involves the use of drugs at the same time or in close temporal proximity. RESULTS: Almost 26% of college students reported having engaged in CPU in the past 12 months. Among these students, 37% had engaged in SPU. In the past 30 days, 17% college students had engaged in CPU. Among these, 35% had engaged in SPU. Marijuana was the illicit drug mostly frequently used with alcohol (either as CPU or SPU), especially among males. Among females, the most commonly reported combination was alcohol and prescribed medications. CONCLUSIONS: A high proportion of Brazilian college students may be engaging in polydrug use. College administrators should keep themselves informed to be able to identify such use and to develop educational interventions to prevent such behavior.

Religion as a protective factor against drug use among brazilian university students: a national survey

OBJECTIVE: To investigate the relationship between religiosity and drug use among Brazilian university students. METHODS: This manuscript is part of the "First Nationwide Survey on the Use of Alcohol, Tobacco and Other Drugs among College Students in the 27 Brazilian State Capitals". In this study, 12,595 university students were divided into two groups according to their attendance at religious services: frequent attenders (FR; 39.1%) and non-frequent attenders (NFR; 60.8%). Subsequently, we analyzed their responses to a structured, anonymous questionnaire on drug use and other behaviors. Individual multivariate logistic regression models tested the association between religiosity and drug use (alcohol, tobacco, marijuana and at least one illicit drug). RESULTS: Drug use over the last 30 days was higher among NFR students even after controlling for demographic variables. NFR students were more likely to use alcohol OR = 2.52; 95% CI: 2.08-3.06, tobacco (2.83; 2.09-3.83), marijuana (2.09; 1.39-3.11) and at least one illicit drug (1.42; 1.12-1.79) compared to FR students. CONCLUSION: Religiosity was found to be a strongly protective factor against drug use among Brazilian university students. However, more studies are needed to identify the mechanisms by which religiosity exerts this protective influence.

Comparação do uso de drogas entre universitários brasileiros, norte-americanos e jovens da população geral brasileira / Comparison of drug use between Brazilian and American college students and young Brazilian general population

OBJETIVO: Comparar o uso de drogas entre os universitários e a população geral brasileira, assim como com os universitários norte-americanos, identificando possíveis diferenças de uso pela interferência da cultura. MÉTODOS: Para comparar o uso de drogas na vida entre as populações de interesse, foram utilizados os dados públicos de levantamentos estatísticos brasileiros realizados com universitários e a população geral, assim como levantamento estatístico norte-americano, por meio da comparação de intervalos de confiança (IC 95%). RESULTADOS: O uso de drogas na vida é mais frequente entre os estudantes norte-americanos, que relatam usar mais tabaco, tranquilizantes, maconha, ecstasy, alucinógenos, cocaína, crack e heroína que os universitários brasileiros. Em contrapartida, os universitários brasileiros relatam usar quase duas vezes mais inalantes do que os universitários norte-americanos. Esse padrão se repete ao se analisarem as diferenças intragênero. A isso se soma que os universitários brasileiros parecem envolver-se com mais frequência no uso de bebidas alcoólicas, maconha, tranquilizantes, inalantes, alucinógenos e anfetamínicos que seus pares da população geral brasileira. CONCLUSÕES: Conhecer as particularidades do uso de drogas entre os universitários é de suma importância para a detecção precoce desse consumo. Investimentos nesse segmento e diferenças de sexo devem ser contempladas nas políticas preventivas, assim como na elaboração de estratégias para a redução e o controle desse consumo, como programas de triagem e intervenção breve, uma vez que possuem a melhor relação custo-benefício.

OBJECTIVE: To compare drug use between college students and the general Brazilian population, as well as with American college students' drug use, identifying possible usage differences related to cultural interference. METHODS: To compare lifetime drug use between target populations, public data collected from statistical surveys conducted with Brazilian college students and the general population were used, as well as surveys conducted with American college students. The surveys' confidence intervals (95% CI) were subjects of comparison. RESULTS: Drug use is more frequent among American college students, who use more tobacco, tranquilizers, marijuana, ecstasy, hallucinogens, cocaine, crack cocaine and heroin than Brazilian college students. In contrast, Brazilian college students use nearly the double of inhalants than American college students. This pattern of use is repeated in the analysis of intra-gender differences. Add to this that Brazilian college students seem to engage more frequently in drinking alcoholic beverages and using marijuana, tranquilizers, inhalants, hallucinogens and amphetamines than their peers in the general Brazilian population. CONCLUSIONS: Knowing the particularities of drug use among college students is of paramount importance for the early detection of consumption. Investments in this segment and gender differences should be considered in preventive policies, as well as developing strategies of consumption reduction and control, such as screening programs and brief intervention, due to better cost-effectiveness.

Use of alcohol and other drugs among Brazilian college students: effects of gender and age / Uso de álcool e outras drogas entre universitários brasileiros: efeitos de gênero e idade

OBJECTIVE: To assess the frequency of drug use among Brazilian college students and its relationship to gender and age. METHODS: A nationwide sample of 12,721 college students completed a questionnaire concerning the use of drugs and other behaviors. The Alcohol, Smoking and Substance Involvement Screening Test (ASSIST-WHO) criteria were used to assess were used to assess hazardous drug use. A multivariate logistic regression model tested the associations of ASSIST-WHO scores with gender and age. The same analyses were carried out to measure drug use in the last 30 days. RESULTS: After controlling for other sociodemographic, academic and administrative variables, men were found to be more likely to use and engage in the hazardous use of anabolic androgenic steroids than women across all age ranges. Conversely, women older than 34 years of age were more likely to use and engage in the hazardous use of amphetamines. CONCLUSIONS: These findings are consistent with results that have been reported for the general Brazilian population. Therefore, these findings should be taken into consideration when developing strategies at the prevention of drug use and the early identification of drug abuse among college students.

OBJETIVO: Avaliar a prevalência do uso de drogas entre universitários brasileiros, assim como sua relação com gênero e idade. MÉTODOS: Uma amostra nacional de 12.721 universitários que preecheram um questionário sobre o uso de drogas e outros comportamentos. Os critérios da escala Alcohol, Smoking and Substance Involvement Screening Test (ASSIST-WHO) avaliaram o uso de drogas de risco. Um modelo de regressão logística multivariada testou a associação entre a pontuação do ASSIST-WHO com o gênero, bem como a idade do universitário. O mesmo foi realizado para a medida de uso de drogas nos últimos 30 dias. RESULTADOS: Após o controle de outras variáveis sociodemográficas, acadêmicas e administrativas, os homens foram os mais prováveis de usar e se engajar no uso de risco de esteroides anabolizantes androgênicos, mais do que as mulheres, e para todas as faixas etárias. Por outro lado, mulheres > 34 anos foram mais prováveis de usar e se engajar no uso de risco de anfetaminas. CONCLUSÕES: Estes resultados são consistentes com o que tem sido descrito para a população geral brasileira. Portanto, eles deveriam ser considerados no desenvolvimento de estratégias de prevenção do uso de drogas, bem como para o reconhecimento precoce do abuso de drogas entre universitários.

Drug use in college students: a 13-year trend / Uso de drogas entre alunos universitários: tendências em 13 anos

OBJECTIVE: To analyze drug use trends among college students in 1996, 2001 and 2009. METHODS: A cross-sectional epidemiological study with a multistage stratified cluster sample with 9,974 college students was conducted in the city of São Paulo, southeastern Brazil. An anonymous self-administered questionnaire was used to collect information on drug use assessed in lifetime, the preceding 12 months and the preceding 30 days. The Bonferroni correction was used for multiple comparisons of drug use rates between surveys. RESULTS: There were changes in the lifetime use of tobacco and some other drugs (hallucinogens [6.1% to 8.8%], amphetamines [4.6% to 8.7%], and tranquilizers [5.7% to 8.2%]) from 1996 to 2009. Differences in the use of other drugs over the 12 months preceding the survey were also seen: reduced use of inhalants [9.0% to 4.8%] and increased use of amphetamines [2.4% to 4.8%]. There was a reduction in alcohol [72.9% to 62.1%], tobacco [21.3% to 17.2%] and marijuana [15.0% to 11.5%] use and an increase in amphetamine use [1.9% to 3.3%] in the preceeding 30 days. CONCLUSIONS: Over the 13-year study period, there was an increase in lifetime use of tobacco, hallucinogens, amphetamines, and tranquilizers. There was an increase in amphetamine use and a reduction in alcohol use during the preceding 12 months. There was an increase in amphetamine use during the preceding 30 days.

OBJETIVO: Analisar a tendência do uso de drogas entre universitários entre 1996, 2001 e 2009. MÉTODOS: Estudo epidemiológico transversal com 9.974 universitários do município de São Paulo, SP, cuja amostra foi selecionada por estratificação e conglomerados. Adotou-se instrumento de pesquisa de autopreenchimento, anônimo, que caracterizou o uso de drogas por três medidas: uso na vida, nos últimos 12 meses e nos últimos 30 dias. Para comparação de frequências de uso de drogas entre as pesquisas, utilizou-se a metodologia de comparações múltiplas com correção de Bonferroni. RESULTADOS: Houve redução da frequência de estudantes que relataram consumo de drogas entre 1996 e 2009. Houve diminuição do uso de inalantes e aumento do uso de anfetamínicos em todas as medidas avaliadas [4,6% para 8,7% na vida, de 2,4% para 4,5% nos últimos 12 meses e de 1,9% a 3,3% nos últimos 30 dias]. Os alunos das Ciências Humanas relataram uso de drogas com maior frequência [48,6% na vida, 29,0% nos últimos 12 meses e 20,9% nos últimos 30 dias]. CONCLUSÕES: Entre os 13 anos de estudo, houve aumento de uso na vida de tabaco, alucinógenos, anfetaminas e tranquilizantes; além do aumento do uso de anfetaminas nos últimos 12 meses e diminuição do uso de álcool. Em relação aos últimos 30 dias, houve aumento do uso de anfetaminas.

Gender differences in drinking patterns and alcohol-related problems in a community sample in São Paulo, Brazil.

OBJECTIVE: To investigate drinking patterns and gender differences in alcohol-related problems in a Brazilian population, with an emphasis on the frequency of heavy drinking. METHODS: A cross-sectional study was conducted with a probability adult household sample (n = 1,464) in the city of São Paulo, Brazil. Alcohol intake and ICD-10 psychopathology diagnoses were assessed with the Composite International Diagnostic Interview 1.1. The analyses focused on the prevalence and determinants of 12-month non-heavy drinking, heavy episodic drinking (4-5 drinks per occasion), and heavy and frequent drinking (heavy drinking at least 3 times/week), as well as associated alcohol-related problems according to drinking patterns and gender. RESULTS: Nearly 22% (32.4% women, 8.7% men) of the subjects were lifetime abstainers, 60.3% were non-heavy drinkers, and 17.5% reported heavy drinking in a 12-month period (26.3% men, 10.9% women). Subjects with the highest frequency of heavy drinking reported the most problems. Among subjects who did not engage in heavy drinking, men reported more problems than did women. A gender convergence in the amount of problems was observed when considering heavy drinking patterns. Heavy and frequent drinkers were twice as likely as abstainers to present lifetime depressive disorders. Lifetime nicotine dependence was associated with all drinking patterns. Heavy and frequent drinking was not restricted to young ages. CONCLUSIONS: Heavy and frequent episodic drinking was strongly associated with problems in a community sample from the largest city in Latin America. Prevention policies should target this drinking pattern, independent of age or gender. These findings warrant continued research on risky drinking behavior, particularly among persistent heavy drinkers at the non-dependent level.

CONCLUSIONS: Over the 13-year study period, there was an increase in lifetime use of tobacco, hallucinogens, amphetamines, and tranquilizers. There was an increase in amphetamine use and a reduction in alcohol use during the preceding 12 months. There was an increase in amphetamine use during the preceding 30 days.

Does ragging play a role in medical student depression - cause or effect?

BACKGROUND: Medical students experience a lot of stress what may contribute to symptoms of depression. In this study we set out to look at the environmental factors which may be contributing in one medical school in Brazil. METHODS: We assessed depressive symptoms using Beck's Depression Inventory in 465 and 267 medical students in 2001 and 2006 respectively. We explored possible social and environmental causes using qualitative data. RESULTS: Nearly 15% scored above the cut off for depression in both the samples. Males in the pre-clinical stage in 2006 showed an increase in depressive symptoms than males in the same cycle in 2001 (aOR=7.36 [95% CI=0.85-63.5] p=0.07). Qualitative data confirmed that factors such as ragging and low social involvement were correlated with depressive symptoms in pre-clinical stage males. LIMITATIONS: The sample size was small both for quantitative and qualitative aspects of the study. CONCLUSIONS: It appears that ragging plays an important role in the genesis of depressive symptoms in medical students.
