Background and Aim: Considering the fact that injecting drug is the most common way of HIV transmission and having the point in mind that in spite of syringes availability, many of the IDUs still continue sharing needles, determining behaviors which lead them not to use HR packages seems invaluable. Determining the influential factors in sharing needles among IDUs who are Kermanshah's DIC clients and are provided with training program and HR Packages (syringes, needles, bleaching and condoms).
Materials and Methods: These subjects were studied in 2 steps. The first FGD (focus group discussions) and the second a cross sectional study. To gather data that we use a questionnaire based an FGG which includes: general characteristics, characteristics related to drug abuse and information about HIV.
Results: out 437 of cases that took part in the interview, 367 cases were IDUS. Among whom 28% individuals shared needles. The medium age was 33/4 and there was no significant difference between the two age groups. Only 27% were married. 61% of cases were unemployed. The unemployment rate among IDUs who share needles and syringes was a lat more significant (p=000) than those who don't share needles (P=000). The percentage of IDUs who share needles and don't living houses was higher than of those who live in houses (P=000). Most of cases started taking drugs before they were 20 years old.
Conclusion: Low Education degree unemployed, no married. Live in street, start IDUs in low age the period of referring to DIC were the most important factors for share needles injection
