ABSTRACT
ObjectiveTo investigate the factors that influence the first CD4+T lymphocyte counts in newly reported HIV-infected cases aged 50 and above in Dehong Prefecture of Yunnan Province during 2016 to 2021， and to understand the patient immune status and disease progression so as to provide scientific basis for HIV prevention and control strategies in the future. MethodsData was collected from the national HIV/AIDS information system. Multivariate logistic regression was used for the analysis of factors affecting the first CD4+T lymphocyte counts. ResultsA total of 642 cases of HIV infection were newly reported， among them， 571 cases had CD4+T lymphocyte counts and 200 cases （35.03%） had CD4+T lymphocyte counts <200 cells·μL-1. Patients who were in the 50-59 age group， male， divorced or widowed， and less educated were more likely to have CD4+T lymphocyte counts <200 cells·μL-1. Compared with active testing consultants， forced reeducation through labor or drug rehabilitation cases were less likely to have CD4+T lymphocyte counts <200 cells·μL-1. ConclusionThere is no obvious upward trend in newly reported HIV infected persons aged 50 years and above in Dehong Prefecture during 2016 to 2021. However， the situation of CD4+T lymphocyte counts <200 cells·μL-1 is still serious. Attention should be paid to the key groups： male， Chinese nationality， farmers， Han nationality， married or divorced， junior high school education or below， and heterosexual transmission. It is necessary to strengthen the intervention in people aged 50 and above and improve the detection efficiency.
ABSTRACT
ObjectiveTo analyze the prevalence of HCV antibody positive and associated factors among drug users in Dehong Prefecture， Yunnan， and to provide scientific evidence for HCV prevention. MethodsQuestionnaire surveys and serological testing were conducted among 400 drug users continuously selected from four national AIDS sentinel surveillance in Dehong Prefecture between January and July during 2014‒2021. Results11 683 drug users were included. The prevalence of HCV antibody positive was 20.2% overall， and 14.9%， 20.1%， 22.4%， 19.8%， 22.5%， 20.6%， 24.5%， 19.0% from 2014 to 2021， respectively （trend Z=-3.78， P<0.001）. Multivariable analysis indicated the following were independently associated with HCV antibody positive： that older age （OR=1.02， 95%CI： 1.02‒1.03）， male （OR=1.70， 95%CI： 1.19‒2.42）， unmarried （OR=1.64， 95%CI： 1.44‒1.87）， divorced or widowed （OR=1.73， 95%CI： 1.48‒2.02）， Jingpo ethnicity （OR=1.39， 95%CI： 1.19‒1.63）， injection drug use （OR=15.46， 95%CI： 13.13‒18.12）， and HIV infection（OR=4.96， 95%CI：4.12‒5.99）. ConclusionThe prevalence of HCV antibody positive among drug users in Dehong Prefecture is high and increases with some fluctuations during 2014 to 2021， which highlights the need to develop interventions targeting this population.
ABSTRACT
Objective@#To study the prevalence and correlates of unprotected sexual intercourse within HIV serodiscordant couples in Dehong prefecture, Yunnan Province, China, in 2014.@*Methods@#This study was based on the follow-up investigation of "the AIDS cohort of seronegative spouses of HIV-infected individuals in Dehong prefecture" in 2014. The 1 520 participants were HIV seronegative spouses from all five counties/cities of Dehong prefecture who voluntarily participated in the cohort. Inclusion criteria included: having a HIV-positive spouse; ≥16 years of age; having had sexual intercourse with spouse in the past year; and being a resident of Dehong prefecture. Information on HIV-positive spouses were also collected through the local AIDS epidemic database. Chi square analysis was performed to compare differences in the rates of unprotected sexual intercourse between participants with different characteristics and lifestyle choices. Multivariable logistic regression model analysis was performed to determine correlates with unprotected sexual intercourse.@*Results@#The 1 520 participants had a mean age of 38.7±9.4, compared with 39.7±8.9 for their HIV-positive spouses. Among the HIV-positive spouses, 77.8% (1 183/1 520) had been infected for more than 3 years, and 87.6% (1 332/1 520) had received antiretroviral therapy. The prevalence of unprotected sexual intercourse within serodiscordant couples over the past 12 months was 16.1% (244/1 520). The prevalence of unprotected sexual intercourse correlated with the level of education of HIV-negative spouses (illiterate vs. middle school and above, OR=1.58, P=0.044), the number of years since diagnosis of HIV-positive spouses (short vs. long, OR=1.6, P=0.006), antiretroviral therapy of HIV-positive spouses (no vs. yes, OR=2.78, P<0.001), the frequency of sexual intercourse per month (high vs. low, OR=1.66, P=0.019), and whether the couple had children (no vs. yes, OR=1.72, P=0.007).@*Conclusion@#The prevalence of unprotected sexual intercourse within serodiscordant couples in Dehong prefecture was relatively high in 2014. Factors found to correlate with the occurrence of unprotected sexual intercourse within these couples included illiteracy of HIV-negative spouses, short time since diagnosis of HIV-positive spouses and lack of antiretroviral therapy, high frequency of sexual intercourse and no children.
ABSTRACT
<p><b>OBJECTIVE</b>To study the incidence rate and risk factors of HIV infection among sero-negative spouses of people living with HIV/AIDS (HIV/AIDS) in Dehong prefecture, Yunnan province.</p><p><b>METHODS</b>A prospective cohort study was conducted from February 2009 to December 2014 in Dehong prefecture, Yunnan province. Questionnaire survey and HIV related tests were carried out once a year.</p><p><b>RESULTS</b>By the end of December 2014, 2 091 sero-negative spouses had been recruited, of whom 1 692 were followed-up for at least one time. RESULTS showed that 34 new HIV infections were identified within 5 494.52 person years of follow-up, for an overall incidence of 0.62 per 100 person years. HIV incidence rates appeared as 0.79 per 100 person years, 0.62 per 100 person years, 0.47 per 100 person years in 2009-2010, 2011-2012, 2013-2014, respectively. Data from the Cox proportional hazard regression model indicated that risk factors of HIV infection among sero-negative spouses of HIV/AIDS were: non-consistent condom use (HR=4.64, 95%CI: 1.89-11.40,P= 0.001), HIV/AIDS delayed antiviral retrovirus therapy (ART) for more than one year (HR=3.70, 95% CI: 1.44-9.49,P=0.007) after the HIV negative spouses were initially recruited, HIV/AIDS did not receive any ART (HR=3.62, 95% CI: 1.14-11.51,P=0.029).</p><p><b>CONCLUSIONS</b>The incidence of HIV infection among sero-negative spouses in Dehong prefecture was relatively low. Publicity on consistent condom use program should be emphasized among sero-negative spouses of HIV/AIDS, together with the timely provision of ART to those HIV/AIDS.</p>

<p><b>OBJECTIVE</b>To compare follow-up and administration of HIV-infected local Chinese and Burmese in Dehong prefecture of Yunnan province, for scientific development of prevention and control measures.</p><p><b>METHODS</b>14 270 HIV-infected local Chinese and 5 436 HIV-infected Burmese reported from 1989 to December 31, 2013 in Dehong prefecture were recruited as the subjects of study, comparing the differences of follow-up and management, CD4⁺ T lymphocyte count tests and antiretroviral therapy (ART) between the two groups.</p><p><b>RESULTS</b>The proportion of HIV-infected Burmese identified in Dehong prefecture was 27.6% (5 436/19 706) during 1989-2013. The number had been growing rapidly from 17.1% in 1989-2003, 12.4% in 2004 and 14.7% in 2005 to over 51.4% in 2012, hitting 59.4% in 2013 (trends χ² = 1 732.84, P < 0.000 1). The proportion of HIV-infected Burmese among case reports of various characteristics kept rising over the years. By the end of 2013, 8 095 HIV-infected local Dehong residents and 5 326 HIV-infected Burmese were still alive. 95.8% of them were under follow-up, 88.5% having CD4⁺ T lymphocyte count tests, and 78.3% under ART. Among the HIV-infected B urmese, only 19.2% of them were under follow-up, 13.0% having CD4⁺ T lymphocyte count tests, and 6.1% under ART, significantly lower than the local Dehong residents (P < 0.000 1).</p><p><b>CONCLUSION</b>The proportion of follow-up and administration, CD4⁺ T lymphocyte count tests, and ART of HIV-infected Burmese was low in Dehong prefecture, Yunnan province, which called for more effective follow-up and administration measures.</p>
