Background & Aim: Youths are the most at risk group for HIV/AIDS in the world and education of the preventive measurements is the most effective way for decreasing the incidence of HIV/AIDS among them. Due to ever-increasing cases of HIV and the importance of education, we compared the effects of three educational methods (peer education, education by physician and giving pamphlets) on knowledge of female high school students&apos of Kerman shah on HIV/AIDS.

Methods & Materials: One thousand and five hundred female third grade students were recruited from 21 high schools using stratified random sampling method. An average of 73 students were selected from each school and participated in a pre-test exam using a questionnaire. Of 1500 students, 498 and 502 students were taught by general practitioners and peers, respectively. Pamphlets were presented to 500 other students. Twenty days after the educational intervention, the participants were contributed in a post-test exam using the very questionnaire. Data were analyzed using descriptive and inferential statistics via SPSS version 11.5.

Results: The students&apos mean age was 16.78 (SD=0.7). The mean scores of pretests and post-tests in all 3 groups were significantly different (P<0.001). The mean score for the group taught by general practitioners (10.7±3.6) was higher than the scores of other two group scores (8.8±3.4 and 7.3±3.9, respectively for peer education and pamphlet groups) after the interventions. Bonferroni statistical test showed the significant difference (P<0.001).

Conclusion: Education presented by general practitioners seems to be more effective than the other two ways in increasing students&apos knowledge about HIV/AIDS.

Background & Aim: Considering the importance and high prevalence of hepatitis C among substance abusers, especially injection drug users, this study aimed to determine the prevalence and risk factors of Hepatitis C in self-introduced substance abusers in Farabi Addiction Hospital in Kermanshah in 2007.

Methods & Materials: A total of 263 drug addicts&apos medical files were assessed during the study. Data (individual characteristics and results of serological tests) were gathered through the files. Data were analyzed by measuring frequency of correlation between the variables (Chi square test and logistic regression).

Results: The mean age was 31.82±9.18 years mean duration of drug abuse was 121.7±29.1 months for prisoners. From 263 individuals in the study, 22.1% were infected with HCV. The most common ways of substance use were injection (33.1%), and fumigation (32.3%). There was no history of imprisonment in 74.9% of individuals and 52.9% had no history of drug injection. There was a history of physical or mental disorder in 25.5% of individuals. The Chi square statistical test showed significant relationship between HCV infection and substance abuse, and the way of consumption and the t-test showed significant relationship with average daily consumption frequency. The highest relative risk ratio was for positive history of physical or mental illness (OR=8.33), and positive history of imprisonment (OR=5.94). Having multiple sexual partners increased the risk of being infected with the HCV (OR=2.92).

Conclusion: The risk of HCV infection was independently increased with having a history of imprisonment, having multiple sexual partners, presence of physical or mental illnesses, and consumption methods in substance abusers.
