Sub-Saharan Africa has the highest incidence of cervical cancer globally. However, compared to developed countries, the region has lower uptake of cervical cancer screening. Research contribution and progress in the field of cervical cancer in the region has not been well investigated. This bibliometric review aimed to address this information gap by examining changes in research volume and type over a 20 year time frame. Medline, Embase, PsycINFO, CINAHL, and Cochrane Library were searched to identify peer-reviewed publications about cervical cancer screening in sub-Saharan Africa. Changes (from 2001 to 2020) in the (i) total publications, (ii) number and proportion of data-based publications relative to non-data-based publications, and descriptive relative to intervention publications, and (iii) the number and proportion of publications meeting the EPOC design criteria relative to those not meeting the EPOC design criteria were assessed using a generalised linear Poisson model, a generalised binomial model and the Pearson Chi-squared test respectively. A two-year increase in time was associated with an estimated 32 % increase in the total number of publications. While no measurement studies were recorded, the bulk of data-based publications (89 %) were descriptive studies. Relative to descriptive publications, a 1 % increase in the proportion of intervention publications was observed over time. Only a small proportion (28 %) of intervention studies met the EPOC design criteria. Our findings suggest that researchers and funders in the region should invest more effort and money in measurement and rigorous intervention research to inform outcome measures and cervical cancer screening policy and practice, respectively.
撒哈拉以南非洲地区的宫颈癌发病率居全球之首。然而，与发达国家相比，该地区的宫颈癌筛查普及率较低。该地区在宫颈癌领域的研究贡献和进展尚未得到充分调查。本研究旨在通过考察 20 年来研究数量和类型的变化，填补这一信息空白。通过检索 Medline、Embase、PsycINFO、CINAHL 和 Cochrane Library，确定了关于撒哈拉以南非洲地区宫颈癌筛查的同行评议文献。采用广义线性泊松模型、广义二项式模型和 Pearson Chi-squared 检验，评估了（i）总出版物数量、（ii）基于数据的出版物数量和比例相对于非基于数据的出版物、描述性出版物相对于干预性出版物的变化，以及（iii）符合 EPOC 设计标准的出版物数量和比例相对于不符合 EPOC 设计标准的出版物数量和比例的变化。时间每增加两年，估计出版物总数就会增加 32%。虽然没有记录到测量研究，但大部分基于数据的出版物（89%）都是描述性研究。与描述性出版物相比，干预性出版物的比例随着时间的推移呈上升趋势。只有一小部分（28%）的干预研究符合 EPOC 设计标准。我们的研究结果表明，该地区的研究人员和资助者应加大投入，开展更多的测量和严格的干预研究，分别为评估结果指标和宫颈癌筛查政策和实践提供信息。
