Epidemiological analyses of regional and age differences of HIV/AIDS prevalence in China, 2004-2016.

Objectives: To describe the prevalence of HIV/AIDS in China from 2004 to 2016 and to assess whether regional and age differences exist with HIV/AIDS infection.

Methods: We searched the Chinese Public Health Science Data Center by the keywords of "HIV" or "AIDS", and collected the data referred to HIV/AIDS morbidity, mortality, and new HIV infection rate, 2004 to 2016.

Results: The HIV/AIDS morbidity, mortality, and new HIV infection rate continually increased per year in China from 2004 to 2016 (0.235, 0.057 and 1.020 in 2004; 3.990, 1.034 and 6.442 in 2016 respectively) (all p<0.001). The middle-aged HIV/AIDS populations showed the highest infection and regional difference significantly existed in the geographical distribution of HIV/AIDS prevalence.

Conclusions: Our analyses of HIV/AIDS prevalence during more than a decade indicate that HIV/AIDS prevalence is getting more and more serious and the rapid spread of HIV exists with the characteristics of regional and age differences.
