目的：了解云南省德宏州成年艾滋病患者抗病毒治疗（ART）脱失比例及其原因。方法对德宏州截至2014年9月30日的参加ART的8367名成年艾滋病患者脱失情况进行调查。结果德宏州累计接受ART的成年艾滋病患者中脱失比例为14.4%（1202/8367）。单因素logistic回归分析，ART脱失与患者所在县（市）、性别、年龄、婚姻状况、感染途径、基线CD4^＋T淋巴细胞计数和初始治疗方案有关。多因素logistic回归分析，ART脱失与患者所在县（市）、婚姻状况、感染途径、基线CD4^＋T淋巴细胞计数和初始治疗方案有关。芒市、梁河县、盈江县、已婚或同居、性传播、基线CD4^＋T淋巴细胞计数≤200 cells/mm^3、初始治疗方案含齐多夫定（AZT）者脱失比例低；瑞丽市、未婚、注射吸毒、基线CD4^＋T淋巴细胞计数＞200 cells/mm^3、初始治疗方案不含AZT者脱失比例高。ART患者随着治疗时间的延长，其脱失比例下降。调查发现1202例脱失治疗的患者中，失访704例（58.6%）、依从性困难303例（25.2%）、外出74例（6.2%）、缅甸籍回国64例（5.3%）、医嘱停药29例（2.4%）、羁押18例（1.5%）、其他原因10例（0.8%）。不同特征患者其脱失原因不同。结论德宏州不同特征的艾滋病患者ART脱失比例不同，需采取针对性的措施以减少脱失，重点是减少失访和提高治疗依从性。

英文摘要：

Objective To examine the proportion and reasons of drop-out from antiretroviral therapy（ART）among 8 367 adult HIV-infected individuals in Dehong prefecture,Yunnan province. Methods All adult HIV-infected patients receiving ART before September 30 of 2014 were examined for the situation of drop-out from ART. Results The proportion of drop-out from ART among adult HIV-infected patients in Dehong prefecture was 14.4%（1 202/8 367）. Results from the univariate logistic regression analyses indicated that drop-out from ART was significantly correlated with factors as：living area,gender,age,marital status,HIV transmission route,baseline CD4^＋T cell counts and initial treatment regimen of the patients. After adjusted for potential confounding variables by multiple logistic regression model,drop-out from ART was significantly correlated with residential area,marital status,HIV transmission route,baseline CD4^＋T cell count and initial treatment regimen of the patients. HIV-infected patients who were living in Mangshi city,Lianghe county or Yingjiang county,being married or living with partner,HIV infection through sexual contact,with baseline CD4^＋T cell counts≤200 cells/mm^3,and ART included in the initial treatment regimen etc.,were less likely to drop out from ART. The proportion of drop out from ART was significantly decreasing along with the increasing time of ART. Data from specific investigation revealed that among the 1 202 patients who dropped out from ART,704（58.6%）were lost to follow-up,303（25.2%） did not adhere to treatment,74（6.2%）moved out the region,64（5.3%）were Burmese that had returned to Burma,29 （2.4%） stopped the treatment according to doctors’advice,18（1.5%）were incarcerated and 10 （0.8%） were under other reasons. Reasons for the drop-out varied,according to the situation of patients. Conclusion The proportion of drop-out from ART varied significantly according to the characteristics of HIV-infected patients in Dehong prefecture that underscoring the needs
