Most HIV research in Sub-Saharan Africa (SSA) ignores persons aged 50 years and above, though a few studies have reported a high HIV prevalence among older people. This study aimed to estimate socio-demographic inequalities in HIV testing behaviour and HIV prevalence among adults aged 50+ years, living in Ifakara town, Tanzania. This cross-sectional study used data from the baseline measurement of the Ifakara MZIMA cohort study in 2012/13. Consenting participants were interviewed and tested for HIV. Associations between HIV testing behaviour and HIV prevalence with socio-demographic indicators were explored with multivariable logistic regression. Among the 1643 adults 50+ years included in the study, HIV prevalence and the HIV testing rate (ever tested) were 6% and 11.4% respectively. The HIV testing rate was lower for older people (aOR = 0.19 (95% CI 0.09-0.41 for 75+ versus 50-54 years); higher for those separated/divorced/widowed than those married (aOR = 1.46; 1.02-2.10); higher for "other Christians" than Muslims (aOR = 1.95; 1.06-3.58); and higher for primary (aOR = 1.54; 1.01-2.33) and secondary (aOR = 3.47; 2.11-5.70) school graduates than those without education. HIV prevalence was lower for older people (aOR = 0.27; 0.11-0.66 for 75+ versus 50-54); and for Catholics compared to Muslims (aOR = 0.54; 0.34-0.85). The high HIV prevalence among older adults and the low HIV testing behaviour call for more efforts on HIV prevention, treatment and care.
撒哈拉以南非洲（SSA）的大多数艾滋病病毒研究都忽视了50岁及以上的人群，尽管有一些研究报告称老年人中的艾滋病病毒感染率很高。本研究旨在估计坦桑尼亚伊法卡拉镇50岁及以上成年人在艾滋病病毒检测行为和艾滋病病毒感染率方面的社会人口不平等情况。这项横断面研究使用了2012/13年伊法卡拉MZIMA队列研究基线测量的数据。同意参与的参与者接受了访谈和艾滋病病毒检测。通过多变量逻辑回归探讨了艾滋病病毒检测行为和艾滋病病毒感染率与社会人口指标之间的关联。在该研究纳入的1643名50岁及以上成年人中，艾滋病病毒感染率和艾滋病病毒检测率（曾经检测过）分别为6%和11.4%。老年人的艾滋病病毒检测率较低（75岁及以上与50 - 54岁相比，调整后比值比[aOR]=0.19[95%置信区间0.09 - 0.41]）；分居/离婚/丧偶者的检测率高于已婚者（aOR = 1.46；1.02 - 2.10）；“其他基督教徒”的检测率高于穆斯林（aOR = 1.95；1.06 - 3.58）；小学（aOR = 1.54；1.01 - 2.33）和中学（aOR = 3.47；2.11 - 5.70）毕业生的检测率高于未受过教育者。老年人的艾滋病病毒感染率较低（75岁及以上与50 - 54岁相比，aOR = 0.27；0.11 - 0.66）；天主教徒的感染率低于穆斯林（aOR = 0.54；0.34 - 0.85）。老年人中较高的艾滋病病毒感染率和较低的艾滋病病毒检测行为表明需要在艾滋病病毒预防、治疗和护理方面做出更多努力。
