The HIV/AIDS epidemic is a major problem around the world and an increasing percentage of new HIV cases is reported to be by sexual transmission. Many studies have been carried out in the field of peer education on HIV/AIDS among young people, however, few studies focused on the long-term effect of this education. To evaluate both the short- and long-term effects of the peer education programme, we conducted a follow-up study to evaluate the related knowledge, attitudes and behaviour intention to HIV/AIDS among senior high-school students in Shanghai, China. We selected 1950 students from 10 senior high schools in Shanghai, from whom 968 students were selected at random for the intervention group and 982 students for the control group. The same questionnaires were carried out before intervention, one month and one year later in both the groups. In the intervention group, the knowledge score of reproductive health, HIV/AIDS and sexually transmitted disease rose from 21.66 to 31.72 one month later (P < 0.001). After one year it was still 30.97, and there was no significant difference between one month and one year (P > 0.05). The behaviour intention to HIV/AIDS prevention, such as condom use during sexual intercourse also changed before and after the intervention. After both the one month and one-year follow-up intervention, we found that more students declared that they would use condoms during sexual intercourse when compared with the control group (P < 0.001). No change was seen in either knowledge or behaviour intention in the control group. These results showed that peer education on HIV/AIDS prevention among high-school students is both effective in promoting knowledge and in changing behaviour intention long term.

"Previous studies have shown gaps in the HIV knowledge of young adults [12-17]. Different interventions to improve this knowledge have been described, with varying degrees of success [18-21]. Improving knowledge can have different secondary goals: reducing sexual risk behaviour, improving condom use or establishing better attitudes towards people living with HIV (PLWH) [22-24]. "
[Show abstract][Hide abstract] ABSTRACT: Background
Adolescents are a risk group for acquiring sexually transmitted diseases, including HIV. Correct knowledge about transmission mechanisms is a prerequisite to taking appropriate precautions to avoid infection. This study aimed at assessing the level of HIV-related knowledge among university students as a first step in developing targeted interventions. We used a self-developed HIV knowledge questionnaire, supplemented with socio-demographic and sexual behaviour questions. The questionnaire was composed of 59 items from different existing questionnaires. It included general statements and statements about prevention, transmission and treatment of HIV.
There were 357 (79.7%) female and 93 (20.3%) male participants and their median age was 20 (IQR 19–21). On average 42/59 (71.2%) questions were answered correctly, 5/59 (8.5%) were answered incorrectly and 12/59 (20.3%) were unknown . The best and worse scores were seen on the prevention questions and the treatment questions, respectively. HIV-related knowledge is higher in older students and in students with a health-related education. Students with sexual experience, with five or more partners and students who have been tested on STDs have a higher HIV-related knowledge.
Knowledge on prevention and transmission of HIV is fairly good among university students and knowledge is higher among students with more sexual experience. They still have some misconceptions (e.g. HIV is spread by mosquitoes) and they are ignorant of a substantial number of statements (e.g. risk for infection through oral sex).

[Show abstract][Hide abstract] ABSTRACT: Relatively little is known about the peer influence in health behaviors within university dormitory rooms. Moreover, in China, the problem of unhealthy behaviors among university students has not yet been sufficiently recognized. We thus investigated health behavior peer influence in Peking University dormitories utilizing a randomized cluster-assignment design.
Cross-sectional in-dormitory survey. Study population: Current students from Peking University Health Science Center from April to June, 2009.
Self-reported questionnaire on health behaviors: physical activity (including bicycling), dietary intake and tobacco use.
Use of bicycle, moderate-intensity exercise, frequency of sweet food and soybean milk intake, frequency of roasted/baked/toasted food intake were behaviors significantly or marginally significantly affected by peer influence.
Health behavior peer effects exist within dormitory rooms among university students. This could provide guidance on room assignment, or inform intervention programs. Examining these may demand attention from university administrators and policy makers.
"Three intervention groups: (a) information-only control group; (b) psychosocial sexual risk-reduction group; (c) psychosocial sexual risk reduction + motivational enhancement therapy targeting reduction of alcohol-related sexual risk. Cai et al. (2008) "
[Show abstract][Hide abstract] ABSTRACT: Concepts of choice are often drawn upon within sexual health promotion discourses to encourage young people to take “responsibility” for and promote their own sexual health and reproductive control. A systematic literature search using predefined inclusion criteria identified peer-reviewed articles focusing on sexual health interventions for young people. Discourse analysis was used to interrogate how concepts of choice were articulated or inferred within the interventions. Of the eligible studies (n = 30), 16 were based on theories of behavioral change, suggesting a linear pathway between choice and improvements in sexual health. Studies that accounted for contextual factors were a minority (n = 6). Overall, study reports offered a limited account of the “situatedness” of young people’s opportunities to exercise choice. This reliance had a tendency to position young people as passive recipients of interventions which seemed to undermine the more active notion of “making choices” presented within these frameworks.
