[HIV/AIDS epidemic situation and data analysis among young students from 2006-2009 in China].

OBJECTIVE

To analyze the HIV/AIDS epidemic situation and related behavioral components among young students in the last years and to provide information for integrated control and prevention programs.

METHODS

Data on young students (15 - 24 years) through case reporting system was collected from 2006 to 2009 and continuous sentinel surveillance data regarding 6 national sentinel sites carried out from 2006 to 2009 was also collected. The sentinel sites would include universities, junior college and secondary vocational colleges registered students, using cluster sampling phases method. Self-administered questionnaire survey and blood (HIV antibody testing and syphilis antibody testing) tests were carried out, with the sample size was about 800 cases per site per year.

RESULTS

The number of case report on HIV/AIDS among the young students of 15 - 24 years age group had been rising. Similar trend was also observed on the number of reported cases over the years, accounting for the proportions of the total number of reported cases, as 0.39%, 0.50%, 0.83% and 1.02% respectively from 2006 to 2009. Sexual contacts continued to be the major route of transmission, with the increasing proportion of homosexual transmission. In the 6 national sentinel sites of young students which continuous surveillance was conducted during the period from 2006 to 2009, data showed the following facts as: proportion (median) of objects who admitted to have had sex, were: 4.3%, 4.5% and 6.1%, proportions (median) of commercial sex occurred in the past year were: 0.3%, 0.2% and 0.3%; proportions (median) of MSM occurred in the past year were: 0.7%, 0.2% and 0.2%; median of HIV antibody positive rate and syphilis antibody positive rate were 0%; median of awareness rate on HIV/AIDS were: 49.0%, 75.0% and 80.5%; proportion (median) of monitor objects who received intervention services in the past year were: 44.2%, 54.3% and 50.2% respectively.

CONCLUSION

In recent years, the HIV/AIDS number through case reporting system on the young students under 15 - 24 years age group, was increasing, but the HIV prevalence among young students was still relatively low, in general. The main transmission was sexual. Some young students had been engaged in commercial sex and MSM activities. Health education should be strengthened to increase the awareness of young students on AIDS/STD prevention. It is necessary to take more effective intervention measures to decrease new infection and control HIV/AIDS epidemic among young students.
