Abstract:
Objective:To analyze the trends in new diagnosis rates of HIV/AIDS cases in Huzhou City, Zhejiang Province from 2009 to 2023, so as to provide the basis for improving HIV/AIDS prevention and control strategies.
Methods:Data of newly reported HIV/AIDS cases in Huzhou City from 2009 to 2023 were collected through the Chinese Disease Prevention and Control Information System. The new diagnosis rate was calculated as the ratio of newly reported HIV/AIDS cases within one year to the permanent resident population during the same period. The gender, age, and regional distribution characteristics of new diagnosis rates of HIV/AIDS cases were described. The trends were analyzed using average annual percent change (AAPC) and annual percent change (APC).
Results:A total of 2 088 new HIV/AIDS cases were reported in Huzhou City from 2009 to 2023, with an average annual new diagnosis rate of 4.53/105. The new diagnosis rates showed an overall increasing trend from 2009 to 2023 (AAPC=12.745%, P<0.05), with rapid growth during 2009 to 2015 (APC=32.734%, P<0.05) but no significant trend during 2015 to 2023 (P>0.05). The average annual new diagnosis rate was significantly higher in males than in females (7.54/100 000 vs. 1.40/100 000, P<0.05). Male new diagnosis rate trend closely mirrored the overall population pattern, while females showed a continuous upward trend without clear inflection point (AAPC=12.575%, P<0.05). Age-specific analysis revealed average annual new diagnosis rates of 2.75/100 000, 6.16/100 000 and 3.83/100 000 for AIDS/HIV cases aged <25, 25-<50 and ≥50 years, respectively. The cases aged <25 years showed no significant trend (P>0.05), while the cases aged 25-<50 and ≥50 years followed patterns similar to the overall population. The average annual new diagnosis rates of HIV/AIDS cases in Wuxing District, Nanxun District, Deqing County, Changxing County and Anji County were 6.54/100 000, 3.43/100 000, 3.45/100 000, 3.56/100 000 and 4.94/100 000, respectively, showing overall upward trends (AAPC=9.672%, 27.599%, 11.800%, 18.896% and 10.254%, all P<0.05).
Conclusions:The new diagnosis rate of HIV/AIDS cases showed an overall upward trend in Huzhou City from 2009 to 2023. Cases are mainly concentrated among males, people aged 25-<50 years and Wuxing District, making them key targets for HIV/AIDS prevention and control.
