To compare nationally representative trends in self-reported uptake of HIV testing and receipt of results in selected countries prior to treatment scale-up.
Demographic and Health Survey (DHS) data from 13 countries in sub-Saharan Africa were used to describe the pattern of uptake of testing for HIV among sexually active participants. Univariate and multivariate logistic regression were used to analyse the associations between socio-demographic and behavioural characteristics and the uptake of testing.
Knowledge of serostatus ranged from 2.2% among women in Guinea (2005) to 27.4% among women in Rwanda (2005). Despite varied levels of testing, univariate analysis showed the profile of testers to be remarkably similar across countries, with respect to socio-demographic characteristics such as area of residence and socio-economic status. HIV-positive participants were more likely to have tested and received their results than HIV-negative participants, with the exception of women in Senegal and men in Guinea. Adjusted analyses indicate that a secondary or higher level of education was a key determinant of testing, and awareness that treatment exists was independently positively associated with testing, once other characteristics were taken into account.
This work provides a baseline for monitoring trends in testing and exploring changes in the profile of those who get tested after the introduction and scale-up of treatment.
比较治疗扩大前选定国家报告的 HIV 检测和检测结果获得情况的全国代表性趋势。
使用来自撒哈拉以南非洲 13 个国家的人口与健康调查（DHS）数据，描述性活跃参与者中 HIV 检测采用情况的模式。使用单变量和多变量逻辑回归分析社会人口学和行为特征与检测采用之间的关联。
知晓血清阳性率从 2005 年几内亚妇女的 2.2%到 2005 年卢旺达妇女的 27.4%不等。尽管检测水平各异，但单变量分析表明，在居住地区和社会经济地位等社会人口学特征方面，各国检测者的特征非常相似。HIV 阳性参与者比 HIV 阴性参与者更有可能接受检测并获得结果，塞内加尔的女性和几内亚的男性除外。调整后的分析表明，中等或高等教育程度是检测的关键决定因素，一旦考虑到其他特征，意识到治疗方法的存在与检测呈独立正相关。
这项工作为监测检测趋势以及探索治疗扩大后接受检测者的特征变化提供了基线。
