摘要
目的了解1989--2011年云南省德宏州HIV感染者死亡率及其影响因素。方法以德宏州1989--2011年报告的所有现住址为本地的HIV感染者为研究对象，收集其死亡相关信息，计算死亡率和累积生存率，并应用Cox比例风险回归模型分析死亡的影响因素。结果共有13006例HIV感染者纳入分析，男性占73．2％，农民占79．1％，48．7％已婚有配偶，少数民族占64．5％，68．7％为文盲或小学文化程度。研究对象累计观察55962．30人年，死亡4648人，死亡率为8．31／100人年。死亡率在1990-2004年间总体呈上升趋势，自2005年起开始持续下降。研究对象自报告发现HIV感染至观察期末的平均生存时间为9．48年，其中，接受过抗病毒治疗者的平均生存时间为16．65年，而从未接受过抗病毒治疗者的平均生存时间为7．67年。多因素分析显示抗病毒治疗以及年龄、性别、民族、职业、婚姻状况和文化程度等社会人口学因素显著影响HIV感染者的死亡和生存状态。结论包括抗病毒治疗在内的艾滋病综合防治措施有效地降低了德宏州HIV感染者的死亡率，今后仍需扩大抗病毒治疗覆盖面，并针对HIV感染者的社会人口学特征加强分类管理和随访，以减少HIV感染者死亡。
Objective To examine the mortality and risk factors among HIV-infected patients during 1989-2011 in Dehong prefecture, Yunnan province. Methods All HIV-infected patients reported during 1989-2011 in Dehong prefecture who held local residency were included in the study. Mortality rates and cumulative survival rates were calculated. Multiple regression analysis under Cox proportional hazard model was conducted to examine the risk factors for deaths. Results A total of 13 006 HIV-infected patients were included in this study including 73.2% males, 79.1% peasants and 48.7% married at the time of reporting. 64.5% of the patients were ethnic minorities, and 68.7% were illiterate or having received only primary school education. All the patients were followed-up for a total of 55 962.30 person-years with 4648 patients died, with overall mortality rate as 8.31/100 person-years. The mortality rate had been increasing from 1990 to 2004 but decreasing since 2005. The average survival time since the identification of HIV infection was 9.48 years overall, and was 16.65 years for those having received antiretroviral treatment （ART） and 7.67 years for those without ART. Data from multiple regression analysis indicated that ART and socio-demographic characteristics such as age, gender, ethnicity, occupation, marital status, education background etc. were significantly associated with death among HIV-infected patients. Conclusion The comprehensive AIDS campaigns including ART had significantly reduced the deaths among HIV-infected patients in Dehong prefecture. More efforts on the scaling up program of ART as well as the enhanced management and follow-up program tailored for HIV-infected patients with different socio- demographic characteristics were needed to further reduce the deaths in the area.
