Sociodemographic and clinical profile of crack cocaine treatment-seeking individuals living in "Crackland", Brazil / Perfil sociodemográfico e clínico de indivíduos em busca de tratamento para o uso de crack que vivem na "Cracolândia"

OBJECTIVE: São Paulo's Crackland is the biggest and oldest open drug use scene in Brazil, yet little is known about the profile of crack cocaine treatment-seeking individuals living in this region. The aim of this crossectional study was to describe the demographics and clinical characteristics of treatment-seeking crack users living in the Crackland region. METHODS: A sample of nighty eight individuals were screened for DSM-V substance use disorders, including substance use, impulsiveness, and psychiatric symptoms. Recent crack cocaine use was also tested using biologic specimens. RESULTS: Results indicated severe social vulnerability, as participants experienced high rates of homelessness (46.9%), unstable housing (50%), unemployment (60.4%) and early school drop-out (27.5%). The average age of crack use onset was 20 years (SD = 6.9) and the mean duration of continuous crack use was 15 years (SD = 9.7). Most participants presented with concomitant mental health disorders, particularly alcohol use disorder (87.8%), as well high rates of psychiatric symptomatology and impulsiveness. More than half of the sample reported at least one previous inpatient (73.5%) and outpatient (65.3%) addiction treatment attempt. CONCLUSION: This population profile should inform mental healthcare services, promoting the provision of tailored assistance by targeting specific demands at all levels of treatment.

OBJETIVO: Localizada em São Paulo, a Cracolândia é o maior e mais antigo cenário aberto de uso de drogas do Brasil. Ainda assim, pouco se sabe sobre o perfil dos indivíduos que vivem nessa região e buscam tratamento para crack. O objetivo deste estudo transversal foi descrever características demográficas e clínicas de usuários de crack vivendo na região da Cracolândia que estão em busca de tratamento. MÉTODOS: Noventa e oito indivíduos foram avaliados para transtornos por uso de substâncias do DSM-V, padrão de uso de substâncias, impulsividade e sintomatologia psiquiátrica. O uso recente de crack também foi determinado por meio de coleta de amostras toxicológicas. RESULTADOS: Os resultados indicaram grave vulnerabilidade social, com significativas prevalências de falta de moradia (46,9%), moradia instável (50%), desemprego (60,4%) e abandono escolar precoce (27,5%). A idade média de início do uso de crack foi de 20 anos (DP = 6,9) e a duração média do uso contínuo do crack foi de 15 anos (DP = 9,7). A maioria dos participantes apresentou alguma comorbidade psiquiátrica, particularmente transtorno por uso de álcool (87,8%), bem como altas taxas de sintomatologia psiquiátrica e impulsividade. Mais da metade da amostra relatou pelo menos uma tentativa anterior de tratamento por internação (73,5%) e ambulatorial (65,3%). CONCLUSÃO: Os achados desse estudo permitem um maior entendimento do perfil e das necessidades de usuários de crack vivendo na região da Cracolândia e podem ajudar serviços de saúde especializados em dependência química a promoverem uma assistência mais direcionada às demandas específicas dessa população.

HIV and syphilis infections and associated factors among patients in treatment at a Specialist Alcohol, Tobacco, and Drugs Center in São Paulo's "Cracolândia"

Abstract Introduction This study describes the epidemiological scenario of human immunodeficiency virus (HIV) and syphilis at the biggest specialist drug addiction center in Brazil. The great challenge is to find strategies to reduce the impact of inequality and discrimination and develop policies to protect individuals living with - or at risk of - infections. Methods During the period from January 1 to May 31, 2016, a cross-sectional study was conducted on which all patients (N = 806) seeking inpatient treatment were enrolled. A structured diagnostic interview and rapid tests were conducted initially, and diagnoses were confirmed by tests conducted at a venereal disease research laboratory (VDRL). Results HIV and syphilis rates were 5.86% and 21.9%, respectively. Women were nearly 2.5 times more likely to have syphilis. HIV infection was associated with unprotected sex (odds ratio [OR]: 3.27, p = 0.003, 95% confidence interval [95%CI]: 1.51-7.11), and suicidal ideation (OR: 6.63, p = 0.001, 95%CI: 3.37-14.0). Although only 1.86% reported injecting drugs at any point during their lifetimes, this variable was associated with both HIV and syphilis. Elevated rates of HIV and syphilis were observed in the context of this severe social vulnerability scenario. Conclusion The risk factors identified as associated with HIV and syphilis should be taken into consideration for implementation of specific prevention strategies including early diagnosis and treatment of sexually transmitted infections (STI) to tackle the rapid spread of STIs in this population.

Suicidal behavior among substance users: data from the Second Brazilian National Alcohol and Drug Survey (II BNADS)

Objective: To investigate the prevalence rates of suicidal ideation (SI) and suicide attempts (SA) and their association with substance use in a nationally representative sample of Brazilians. Methods: The Second Brazilian National Alcohol and Drug Survey (II BNADS) is a household cross-sectional survey that investigated the consumption of psychotropic drugs and associated risk factors. This national probability sample survey used a multistage cluster design to select 4,607 participants aged 14 or older and had a total response rate of 77%. Illegal drug use, SI and SA were obtained by confidential self-report assessment. Results: SI and SA were reported by 9.9 and 5.4% of the sample, respectively. This prevalence was 20.8 and 12.4% among individuals with alcohol use disorders (AUD), 31.5 and 16.5% among cannabis users and 40.0 and 20.8% among cocaine users. After adjusting for demographic characteristics, tobacco use, family history of suicide and depression, both SI and SA were positively associated with AUD, cannabis and cocaine use. Conclusion: AUD, cannabis and cocaine use were significantly associated with SI and SA, even after the adjustments. Public health initiatives targeting suicide prevention should consider including assessment and management of substance misuse, and therapeutic approaches to substance misuse should include assessment of suicidality.

Alcohol misuse among women in Brazil: recent trends and associations with unprotected sex, early pregnancy, and abortion

Objective: This study compared the rates of binge drinking (BD) and alcohol use disorder (AUD) reported for 2006 with those reported for 2012, exploring their associations with unprotected sex, early pregnancy, and abortion in a representative sample of women in Brazilian households. Methods: This was a descriptive analysis of data from a cross-sectional study involving randomized multistage cluster sampling of the population ≥ 14 years of age. Weighted prevalence rates and odds ratios were estimated, and serial mediation analysis was performed. Results: A total of 4,256 women were analyzed. The BD prevalence was 35.1% and 47.1% in 2006 and 2012, respectively, a significant increase, especially among women 40-59 years of age. There was no significant difference in AUD prevalence. BD (without AUD) was found to increase the odds of unprotected sex and abortion. The path analysis showed that early pregnancy was a mediator of the relationship between alcohol consumption and abortion. Conclusion: Among women in Brazil, the harmful use of alcohol is increasing, which has an impact on female reproductive health and exposure to risks. There is a need for specific prevention initiatives focusing on alcohol-related behaviors in women.

Prevalence of and pathways to benzodiazepine use in Brazil: the role of depression, sleep, and sedentary lifestyle

Objective: This study aimed to determine the prevalence of benzodiazepine (BZD) use in Brazil and to investigate the direct and indirect effects of alcohol consumption, sedentary lifestyle (SL), depressive symptoms (DS), and sleep dissatisfaction (SD) on BZD use. Methods: The Second Brazilian Alcohol and Drugs Survey (II BNADS) used stratified cluster probabilistic sampling to select 4,607 individuals aged 14 years and older from the Brazilian household population. Results: The lifetime and 12-month prevalence of BZD use was 9.8 and 6.1%, respectively. Older participants (age 40 and older) and women had higher rates. Alcohol use disorder, DS, and SD were significantly more prevalent in BZD users. The parallel multiple mediator model showed a positive direct effect of alcohol consumption on BZD use, with significant positive indirect effects of SL, SD, and DS as simultaneous mediators leading to higher BZD intake. Other statistically significant indirect pathways were DS alone, SD alone, and all of the above except SL. Conclusion: The prevalence of BZD use in Brazil is high compared to that of other countries. Knowledge of the main risk factors and pathways to consumption can guide prevention initiatives and underlie the development of better tailored and effective treatment strategies.

Intimate partner violence trends in Brazil: data from two waves of the Brazilian National Alcohol and Drugs Survey

Objective: To compare intimate partner violence (IPV) prevalence rates in 2006 and 2012 in a nationally representative household sample in Brazil. The associations between IPV and substance use were also investigated. Methods: IPV was assessed using the Conflict Tactic Scale-R in two waves (2006/2012) of the Brazilian Alcohol and Drugs Survey. Weighted prevalence rates and adjusted logistic regression models were calculated. Results: Prevalence rates of IPV victimization decreased significantly, especially among women (8.8 to 6.3%). The rates of IPV perpetration also decreased significantly (10.6 to 8.4% for the overall sample and 9.2 to 6.1% in men), as well as the rates of bidirectional violence (by individuals who were simultaneously victims and perpetrators of violence) (3.2 to 2.4% for the overall sample). Alcohol increased the likelihood of being a victim (odds ratio [OR] = 1.6) and perpetrator (OR = 2.4) of IPV. Use of illicit drugs increased up to 4.5 times the likelihood of being a perpetrator. Conclusions: In spite of the significant reduction in most types of IPV between 2006 and 2012, violence perpetrated by women was not significantly reduced, and the current national rates are still high. Further, this study suggests that use of alcohol and other psychoactive drugs plays a major role in IPV. Prevention initiatives must take drug misuse into consideration.
