Uvod: Oko 58 milijuna ljudi ima kroničnu HCV infekciju, a oko 1,5 milijuna ljudi se zarazi svake godine. Cilj: Ispitati stavove i znanje zatvorenika o hepatitisu C, te analizom utvrditi postoji li statistički značajna razlika s obzirom na dob, radni status i stupanj obrazovanja ispitanika. Metode: Istraživanje je provedeno od studenoga 2020. do ožujka 2021. godine u Kaznionici LipovicaPopovača. Kao instrument za provedbu istraživanja koristio se posebno konstruirani anketni upitnik. Rezultati: Sudjelovalo je 133 muških ispitanika u dobi 23-82 godine.Najzastupljeniji sudionici imaju srednjoškolsko obrazovanje - 82 (61,7%). Polovina sudionika je zaposlena, njih 72 (54,1%), a 118 (88,7%) njih je izjavilo da ima znanje o HCV-u. Sudionici imaju nedostatno znanje na pitanja „Testiranje na hepatitis C može se obaviti u svakoj općoj bolnici u Republici Hrvatskoj“ (M=2,17, SD=1,50) i „Treba izbjegavati dodir s oboljelom osobom od hepatitisa C“ (M=2,92, SD=1,50). Upoznati su s tim da bi se osobe rizičnog ponašanja trebale testirati na virus hepatitisa C (M=4,52, SD=0,92), da su testiranje i detekcija najvažniji postupci u prevenciji širenja bolesti (M=4,54, SD=0,88), da besplatna testiranja doprinose većem odazivu na testiranje, što može doprinijeti otkrivanju većeg broja osoba s HCV-om (M= 4,55, SD=0,91), te da je važno imati podršku obitelji i bliskih osoba (M=4,61, SD=0,69). Zaključak: Informiranost o virusnim hepatitisima u zatvorskom sustavu je prisutna, ali je i dalje nedovoljna i zahtijeva ulaganje u ovom području. Rezultati i analiza provedenog istraživanja otvaraju mogućnost za uvođenje standardiziranih javnozdravstvenih programa kojima bi se zatvorska populacija dodatno educirala i promijenila svoj stil života. Introduction: About 58 million people have chronic HCV infection and about 1.5 million people becomeinfected every year.Objective: To examine the attitudes and knowledge of prisoners about hepatitis C and to determine ifthere is a statistically significant difference with regard to age, work status and level of education.Methods: The research was conducted from November 2020 to March 2021 in the Penitentiary inLipovica-Popovača. A specially constructed survey questionnaire was used.Results: 133 male subjects participated aged 23-82 years. Most of the participants finished high school,82 (61.7%). Half of the participants were employed, 72 (54.1%), and 118 (88.7%) stated that they hadknowledge about HCV. The participants showed a lack of knowledge in questions "Testing for hepatitis Ccan be done in every general hospital in the Republic of Croatia" (M=2.17, SD=1.50) and "You shouldavoid contact with a person suffering from hepatitis C" (M =2.92, SD=1.50). They are well aware thatpeople with risky behavior should be tested for the hepatitis C virus (M=4.52, SD=0.92), that testing anddetection are the most important procedures in preventing the spread of the disease (M=4.54, SD=0.88),that free testing contributes to a greater response to testing, which can contribute to the detection of a greaternumber of people with HCV (M= 4.55, SD=0.91) and that it is important to have the support of family andclose people (M=4.61, SD=0.69).Conclusion: Awareness of viral hepatitis in the prison system is present, but is still insufficient andrequires investment in this area. The results and analysis of the conducted research open up the possibilityof introducing standardized public health programs that would further educate the prison population duringserving their sentence changing their lifestyle.
