Factors associated with human immunodeficiency virus infection

Abstract

Objective: to analyze the association between demographic categories and types of exposure. Methods: an analytical cross-sectional study was conducted using data provided by the Paraná State Health Department, from 2010 to 2020. Absolute and relative frequencies were used for the descriptive analysis. Prevalence ratios and their respective 95% confidence intervals were calculated using Poisson regression with robust variance adjustment (significance level of 0.05). Results: most cases were male, of white race, and aged between 18 and 39 years old. In small municipalities, schooling up to eight years prevailed, while in medium and large municipalities, schooling of nine years or more predominated. Associations were found between male gender, the age range of 18 to 39 years old, and categories of exposure to injectable drugs  and heterosexual orientation. In the group with up to 8 years of schooling, there was an association with injectable drugs, transfusion, and men who have sex with men. Conclusion: the use of injectable drugs and heterosexual orientation were exposure categories associated with the male gender and the age range of 18 to 39 years old. Men who have sex with men, cases of transfusion transmission, and users of injectable drugs were associated with up to 8 years of schooling.
