Knowledge of the workers of the construction industry about acquired immunodeficiency syndrome and associated factors.

BACKGROUND: Sexually Transmitted Infections (STIs), such as Human Immunodeficiency Virus (HIV) transmitted by biological, socioeconomic and cultural factors that increase the vulnerability of certain population groups such as civil construction workers. OBJECTIVE: To evaluate the knowledge of workers in the construction industry about infection by HIV and associated factors. METHODS: A cross-sectional, analytical study was conducted, including 381 construction workers, in the cities of João Pessoa, Cabedelo, and Santa Rita, in the State of Paraíba, Brazil, performed through interviews, using a data collection instrument with social demographic variables and the HIV Knowledge Questionnaire. Data were analyzed using descriptive measures, and for comparison between the categories the Kruskal-Wallis test was used, with margin of error of 5%. RESULTS: A predominance of male workers was observed (97.4%) among 381 workers; aged 30-39 (34.1%); married (81.4%); with up to eight years of education (66.6%); family income of up to 2x the minimum wage (52.8%) and coming from the country (43.8%). The average of correct responses was 63.3%, with higher indices (70.0%) related to transmission and forms of prevention. There were higher percentages of hits among those who had studied for 12 years or more. Workers from the capital of Paraíba presented a higher number of correct responses (67.44%). CONCLUSIONS: There is a low index of knowledge of construction workers about HIV, highlighting their consequent vulnerability to acquiring this infection. [ABSTRACT FROM AUTHOR]
