Epidemiological characteristics of people living with HIV/AIDS before and after implementation of classified management

ObjectiveTo understand the epidemiological characteristics of people living with HIV/AIDS before and after the implementation of classified management strategy in Ningbo, China.

MethodsA the end of November 2017, a 1-year follow up was conducted in recruited HIV/AIDS who lived in Ningbo. Different management strategy was implemented in HIV/AIDS with different risk of transmission. The information about their socio-demographics, transmission risk, sex behavior, history of sexually transmitted diseases and antiretroviral therapy were analyzed.

ResultsA total of 2 905 HIV/AIDS were included. After 1 year classified management, the proportion of HIV/AIDS with high transmission risk declined from 11.74% to 5.23% (χ²＝66.786, P＜0.05). The proportion of HIV/AIDS with high risk transmission significantly decrease (P＜0.05) except those who were aged ＜20 years, with education level blow primary school and drug users (P＞0.05). After classified management, the proportion of HIV/AIDS with sexual behaviors, with multi sex partners, using no condoms significantly decreased (P＜0.05); the proportion of HIV/AIDS who were syphilis positive significantly decreased (P＜0.05); the proportion of HIV/AIDS receiving no antiretroviral therapy and viral load ≥400 significantly decreased (P＜0.05).

ConclusionThrough the implementation of classified management strategy, the proportion of HIV/AIDS with high transmission risk in Ningbo significantly decreased, the prevalence of multi sex partners and sexual transmitted diseases in HIV/AIDS A with high transmission risk significantly decreased. In the future, it is necessary to further strengthen the follow up and anti-retroviral therapy in HIV/AIDS with high transmission risk in order to reduce the HIV transmission.
