“…The Marajó Archipelago is located at the mouth of the Amazon River in northern Brazil and is considered to be one of the world's major estuarine archipelagos, although socioeconomic and cultural indices reflect the neglect of local governmental institutions. The lack of infrastructure and public services in the Marajó Archipelago is reflected in widespread poverty, hunger, the sexual abuse and exploitation of children and adolescents, prostitution, and the consumption and trafficking of illicit drugs [12]. The present study is a survey of the use of marijuana and cocaine by students in public schools located in Breves, the largest municipality in the Marajó Archipelago, State of Pará, Brazilian Amazon.…”

IntroductionThe dependence of psychotropic drugs is a great challenge for parents, health professionals, educators, public policy managers, legislators and for the whole community. The impact on society, the economy and the health of this disorder is immense. In the last decades, drug experimentation has been increasingly precocious, with abuse and dependency, despite the fact that preventive efforts are increasing [1, 2]. An individual's first experiences with drugs often take place during adolescence. During this phase, the individual is particularly vulnerable from a psychological and social point of view [3]. Thus, it is particularly important to study this age group in detail, especially in relation to frequent and heavy use of legal and illegal drugs and to identify the psychological and sociocultural factors that are associated with such use [4,5].In Brazil, six major epidemiological studies on the use of licit and illicit drugs were carried out in the last two decades. Alcohol is the most commonly used psychotropic drug. However, the use of marijuana has increased considerably among Brazilian students [4,6,7]. Several national and international studies have analyzed the associations of psychological and socio-cultural factors with AbstractBackground: Globally, the use of illicit drugs is a public health problem. Generally, the use of licit drugs tends to precede and increase the risk of regular use of illicit drugs. Since, the family environment can influence this process. In Brazil, marijuana is the most commonly used illicit drug, especially among adolescent users. In northern Brazil, epidemiological studies of illicit drug use in the population of adolescents and young people are still scarce. This study determined the prevalence and factors associated with the regular use of marijuana and cocaine among high school students in the municipality of Breves, Pará, Brazilian Amazon. Methods:This cross-sectional study was carried out in four high schools in the municipality of Breves, in which a self-filling form was used to collect information and enable the description and analysis of socio-demographic, economic and family conditions related to the regular use of illicit drugs. Chi-Square and Odds Ratio tests were used to indicate and quantify the contribution of factors associated with regular use of illicit drugs.Results: Among 3,218 students, 1,828 (56.8%) agreed to participate in this study. The age range was 14-52 years, with predominance of female students (55.6%). The prevalence of experimentation and regular use of marijuana and cocaine was 8.8% and 4.0%, respectively. The average initial age of use of marijuana and cocaine was 13.5 years. Most students who regularly use illicit drugs use only marijuana (81.1%). Several factors associated with regular use of illicit drugs have been identified. In particular related to social, economic and demographic aspects. Conclusion:The prevalence of students using illicit drugs is moderate in the municipality of Breves. Possibly, regular use of marijuana and ...

“…Neste estudo, uma elevada prevalência de exposição ao HBV foi detectada entre usuários de drogas ilícitas no município de Breves. Apesar desses resultados indicarem o elevado risco de infecção pelo HBV nesse grupo de vulneráveis, quando comparado com a população em geral, eles corroboram com relatos de outros estudos realizados no norte do Brasil (GASPAR et al, 2016;ANDRADE et al, 2017).…”

“…Most of prevalence studies of HBV in illicit substance users (ISU) in Latin America were conducted in Brazil, followed by Argentina, Colombia, Mexico and Uruguay. In Northern Brazil, HBV prevalence (anti-HBc positivity) was 36.7% in ISU, genotypes A, D and F were found and risk factors were: (i) male gender, (ii) age above 35 years, (iii) anti-HIV positivity, (iv) tattoos, (v) the use of injected drugs, (vi) the use of illicit drugs for more than 3 years, (vii) sexual relations without protection, (viii) sexual relations with another DU, and (ix) more than 10 sexual partners in the past 24 months [29].

Latin America includes Mexico, the islands of the Caribbean and Central and South America, which possess a rich cultural and natural heritage. A narrative literature review was made to determine epidemiological hepatitis B and C profiles in high risk groups in Latin America, such as, drug users, hemophiliacs, and chronic kidney disease (CKD), human immunodeficiency virus (HIV) infected individuals. Using data from international databases that disseminate published quality studies. All studies with desired information regarding site and study population were included. It was observed that HBV prevalence diminished in several groups, probably due to implementation of HBV vaccination in various Latin America Countries (LACs). On the other hand, HCV prevalence is high among high risk groups compared to general population, but different values were observed in LAC, probably due to different access to education programs, assays evaluated, population size and type of recruitment. Due to chronicity of HBV and HCV, it is important to increase access to diagnosis, HBV vaccination and implementation of education programs to high risk groups to diminish burden of these infections.
