[Characteristics and trends of HIV/AIDS cases with the non-martial and non-commercial heterosexual transmission in Henan province, 2015-2020]

Objective: To analysis the characteristics and trends of non-martial and non-commercial heterosexual transmission of HIV/AIDS cases in Henan province between 2015 and 2020. Methods: Information of newly reported HIV/AIDS through non-martial and non-commercial heterosexual transmission was collected from National Comprehensive HIV/AIDS Information system, using SPSS 22.0 to analyze the characteristics and tend of cases. Results: During 2015-2020, a total of 10 877 HIV/AIDS cases infected by non-martial and non-commercial heterosexual transmission were newly reported in Henan province. This mode of infection increased from 32.6% in 2015 to 35.5% in 2020 (trend χ²=81.880,P<0.01). The male to female ratio was 1.9∶1 (7 105∶3 772). The mean age was (45.5±15.8) years, increasing annually (F=5.184,P<0.01). For female cases, the proportion of aged 15-50 years group was decreased annually (trend χ²=69.888, P<0.01). Most HIV/AIDS cases were distributed in the early HIV epidemic areas and Zhengzhou city, the same as the cases of the first CD4⁺T cells counts (CD4) below 200 cells/μl. The median (P₂₅, P₇₅) first CD4 count was 298 (143, 462) cells/μl. The proportion of the first CD4<200 cells/μl was no significant change annually, while the proportion of the first CD4≥500 cells/μl was decreasing annually (trend χ²=18.961,P<0.01). Conclusions: The reported cases through non-martial and non-commercial heterosexual transmission increased, with most of them were male, married, junior, farmer, migrant laborer, and aged 40-59 years. It is needed to focus on the rural district and the middle-aged population, combined with biological and social factors to control the prevalence of AIDS through comprehensive prevention and control measures.
