Objectives: to analyze characteristics of homeless people and factors associated with living on the streets. Methods: a census-type sectional survey carried out between 2015 and 2018, in the municipality of Maringá-Paraná. A total of 701 homeless answered a structured questionnaire with sociodemographic data, living conditions, and drug use. We used Pearson’s correlation test for the association analysis of the variables at a 95% confidence level. Results: men (90.7%) the average age of 37.7 years had been homeless for an average of 5.39 years. Most had little education (54.2%), and homelessness was due to drug use (47.2%) and family disagreements (38.9%). Conclusions: drug use and family disagreements were the main reasons for homelessness. Time on the street, gender, and drugs were associated with a negative correlation to be homeless; and age, mean daily income, the number of daily meals, having been in prison, and having an income source were associated with positive correlation.

Objective: to assess risk related to drug use in men admitted to a psychiatric hospital and to identify associations with sociodemographic, socioeconomic variables, and risk conditions. Method: a cross-sectional study with the application of a screening test in 209 participants hospitalized for mental and behavioral disorders due to the use of psychoactive substances. Statistical analysis was performed using descriptive statistics and adjustment of a binary logistic regression model for moderate or high risk of drug use. The odds ratio measured the strength of association. Results: high use in life was observed, with alcohol and tobacco experimentation in adolescence. A high prevalence of related risk was observed for alcohol, tobacco, smoked and inhaled cocaine, and marijuana. Moderate and elevated risks were found for tobacco (22.5% and 62.5%, respectively), alcohol (13.5% and 73%), marijuana (16% and 32.5%), smoked cocaine (3% and 41%) and inhaled cocaine (9% and 19.5%). Conclusion: the results showed high use in life, with an age of early experimentation. Tobacco and alcohol are the main drugs used by hospitalized men.

Objective: to analyze the trend in hospitalization rates for mental and behavioral disorders due to alcohol use (ICD-10: F10.0), Brazil and its five regions, 2010-2020. Methods: this was an ecological time-series study using data from the Hospital Information System of the Brazilian National Health System; to calculate the trend in hospitalizations, we used the Prais-Winsten generalized linear regression model and the Stata Statistical Software 14.0; a decreasing trend was considered when p-value < 0.05, and the regression coefficient was negative. Results: in the period analyzed, there were 423,290 hospitalizations for mental and behavioral disorders due to alcohol use in the country; the data analyzed showed a decreasing trend in adult hospitalization rates for this cause in the country (p-value < 0.001; 95%CI -0.094;-0.079) and in all its regions, for both sexes (p-value < 0.001). Conclusion: hospitalizations for mental and behavioral disorders due to alcohol use have reduced in Brazil and in its macro-regions.

Objective To identify the prevalence of risk related to drug use among workers of a construction company and to evaluate how it relates with sociodemographic variables. Methods A cross-sectional study conducted with 418 workers who were given the Alcohol, Smoking and Substance Involvement Screening Test. Multinominal logistic regression was used as a measure of association. Results Tobacco, alcohol, cannabis, cocaine and inhalants were the most used drugs. Moderate and high risks were related, respectively, to the use of tobacco (32.5% and 5.7%), alcohol (26.8% and 6.9%), cannabis (2.6% and 2.4%) and cocaine (1.2% and 0.5%). Conclusion Tobacco and alcohol were the main drugs used by workers. The level of risk related to the use of tobacco, alcohol, cannabis and cocaine were high when compared to that of the general population.

Objective: to verify the contexts that enhance the dimensions of individual, social, and programmatic vulnerability associated with the use of alcohol and other drugs during pregnancy. Method: qualitative, descriptive, and exploratory, cross-sectional study. Participants were 38 pregnant women who used alcohol and other drugs, at a moderate and severe level, in low-risk prenatal care in the Primary Health Care of two cities in the Metropolitan Region of Maringá - Paraná. Data was collected from, December 2019 to March 2020. The Vulnerability analytical framework guided the discussion. Results: at the individual level, the vulnerability contexts were issues of gender, brown and black ethnicity/color, low education, reproductive period, and high parity. At the social level, the lack of insertion in the job market, family income below the poverty line, abusive intra-family relationships, addictive behavior in the family, and violence in the living community. In the programmatic plan, there was a low demand for health services, lack of welcoming for the treatment of drug use, screening for deficient drug use, low bond with family health teams, absence of dental, psychological, and social services, insertion in the inadequate level of prenatal care, usual risk, while they should have been classified as high risk, and mean prenatal consultations below recommended. Conclusion: the study made it possible to advance in the contexts of the vulnerability of these pregnant women. Recognizing these contexts makes it possible to formulate strategies to reduce harm and damages to maternal and fetal health related to drug use during pregnancy, leading to a favorable gestational outcome.
