Abstract

The aim of the study was to determine additional risk factors that could increase the prevalence of hepatitis C (HCV) infection among injecting drug users (IDU). The study included 327 heroin addicts registered in Zadar County, Croatia. The participants were divided into two groups according to their HCV status. HCV-positive and HCV-negative study participants were compared. HCV-positive group started injecting heroin at earlier age (median 18.5 years) than HCV-negative group (median 20.0 years) (p = 0.032) and had been injecting heroin for a significantly longer period (median 5 years vs. median 4 years, respectively; p < 0.001). IDUs in HCV-positive group shared their injecting equipment significantly more often than IDUs in HCV-negative group (p < 0.001; chi2 = 32.7). The main reasons for starting drugs were curiosity, psychological reasons (depression and/or neurosis), and peer or partner pressure in HCV-positive group, and fun, curiosity, and peer pressure in HCV-negative group (p = 0.051; chi2 = 23.6). Earlier onset of heroin use, longer heroin use, sharing injection equipment, curiosity, and psychological problems as reasons for starting drugs were associated with higher prevalence of HCV infection among injecting heroin users in Zadar County.

Abstract in Croatian

Cilj ove studije je odrediti dodatne faktore rizika koji mogu povećati prevalenciju hepatitisa C (HCV) među intravenskim ovisnicima (IV ovisnici). Studija uključuje 327 heroinskih ovisnika u Zadarskoj županiji, Hrvatska. Sudionici su podijeljeni u dvije grupe prema HCV statusu. HCV-pozitivni i HCV-negativni sudionici su uspoređivani. HCV-pozitivni ovisnici ranije počinju koristiti heroin venskim putem (median 18,5 godina) u odnosu na HCV-negativne (median 20.0 godina) (p=0,032) i duže konzumiraju heroin (median 5 godina; median 4 godine, uzastopce; p<0,001). IV ovisnici HCV pozitivnoj grupi češće se dijele pribor za drogiranje od HCV-negativnih ovisnika (p<0,001: c2=32.7). Glavni razlozi za početak konzumiranja droga u HCV-pozitivnih ovisnika su znatiželja, psihološki razlozi (depresija, neuroza), te utjecaj partnera ili vršnjaka, dok su u HCV-negativnih ovisnika zabava, znatiželja, te utjecaj partnera ili vršnjaka (p=0,051; c2=23,6). Ranije uzimanje heroina, duže uzimanje heroina, dijeljenje zajedničkog pribora, znatiželja i psihološki problemi su razlozi povezani sa visokom prevalencijom HCV infekcijemeđu intavenskim ovisnicima u Zadarskoj županiji.
