目的探索50岁及以上老年人感染艾滋病社会行为学特征的危险因素。方法对广西南宁50岁以上老年病例开展病例对照研究,采取单因素、多因素Logistic回归模型分析老年人感染艾滋病的危险因素。结果调查病例组245人、对照组502人,调查对象年龄最小50岁,最大84岁,平均年龄(63.00±0.75)岁。以男性、汉族、文化程度为初中及以下和农民为主。多因素分析结果显示居住状况(OR=0.437,95%CI:0.246~0.777)、最近半年内性行为对象为配偶(OR=0.307,95%CI:0.112~0.843)、无商业性性行为(OR=0.106,95%CI:0.067~0.168)为老年人HIV感染的保护因素,最近半年内性生活有时或从未使用安全套(OR=24.431,95%CI:5.616~106.281),不知晓艾滋病知识(OR=2.018,95%CI:1.326~3.070)、每月可支配收入中等(OR=2.037,95%CI:1.117~3.714)是危险因素。结论关注老年人孤独感及其性需求、性健康,加强防病知识宣传,推广安全套使用,减少高危行为是预防老年人感染艾滋病的有效途径。

Objective To explore the risk factors of human immunodeficiency virus （HIV） infection among elderly patients over 50 years elderly. Methods Case-control studies were conducted in 50-years-above elderly. Risk factors and protective factors for HIV infection were analyzed by logistic regression analysis. Results Interviewees had 245 HIV-infected individuals （case group） and 502 health people （control group）. Age were 50 -84 years old （mean 63.00±0. 75）. The main social demographic characteristics were male, the Han nationality, illiterate or having received only primaty school education, famers. Logistic single factor analysis and multiple factors regression analysis revealed that, the protective facor were residence status （ OR = 0. 437, 95% CI： 0. 246 - 0. 777 ）, elderly who had sexual behavior with spouse in the last half year （ OR = 0. 307, 95% CI： 0. 112 - 0. 843 ） , elderly who had not commercial sex behavior （ OR = 0. 106, 95% CI： 0. 067 -0. 168）. The risk factors were elderly who had sexxual behavior with no-condoms use in the last half year （ OR = 24. 431, 95% CI： 5. 616 - 106. 281 ）, no-HIV-knowledge （ OR = 2. 018, 95% CI： 1. 326 - 3. 070）, middle-income group （ OR = 2. 037, 95% CI： 1.117 - 3. 714）. Conclusion Focusing solitude and sexual requirement, publicizing HIV prevention knowledge, promoting condom use, reducing high-risk sexual behavior were effective approaches to prevent eld- erly HIV infection.
