BackgroundPrecancerous cervical lesions, or cervical intraepithelial neoplasia (CIN), represent a significant precursor to cervical cancer, posing a considerable threat to women’s health globally, particularly in developing countries. In Africa, the burden of premalignant cervical lesions is not well studied. Therefore, the main purpose of this systematic review and meta-analysis was to determine the overall prevalence of precancerous cervical lesions and identifying determinants among women who underwent cervical cancer screening in Africa.
MethodsThis study followed the Preferred Reporting Item Review and Meta-analysis (PRISMA) guidelines. The protocol for this systematic review and meta-analysis was registered on the International Prospective Register of Systematic Reviews (PROSPERO) (ID: CRD42025645427). We carried out a systematic and comprehensive search on electronic databases such as PubMed and Hinari. In addition, Google Scholar and ScienceDirect were utilized to find relevant studies related to precancerous cervical lesions. Data from the included studies were extracted using an Excel spreadsheet and analyzed using STATA version 17. The methodological quality of the eligible studies was examined using the Joanna Briggs Institute (JBI) assessment tool. Publication bias was checked by using the funnel plot and Egger’s tests. A random-effects model using the Der Simonian Laird method was used to estimate the pooled prevalence of pre-cancerous cervical lesions in Africa. The I-squared and Cochrane Q statistics were used to assess the level of statistical heterogeneity among the included studies.
ResultsA total of 112 eligible articles conducted in Africa, encompassing 212,984 study participants, were included in the quantitative meta-analysis. Thus, the pooled prevalence of pre-cancerous cervical lesions in Africa was 17.06% (95% confidence interval: 15.47%−18.68%). In this review, having no formal education (AOR = 4.07, 95% CI: 1.74, 9.53), being rural dweller(AOR = 2.38, 95% CI: 1.64, 3.46), history of STIs (AOR = 3.94, 95% CI: 2.97, 5.23), history of having multiple partners (AOR = 2.73, 95% CI: 2.28, 3.28), early initiation of coitus (AOR = 2.77, 95% CI: 2.11, 3.62), being HIV-seropositive women (AOR = 3.33, 95% CI: 2.32, 4.78), a CD4 count Conclusions
In Africa, the overall prevalence of pre-cancerous cervical lesions is high (17%). The findings of this review highlight that health professionals, health administrators, and all other concerned bodies need to work in collaboration to expand comprehensive cervical cancer screening methods in healthcare facilities for early detection and treatment of cervical lesions. In addition, increasing community awareness and health education, expanding visual inspection of the cervix with acetic acid in rural areas, offering special attention to high-risk groups (HIV-positive women), encouraging adherence to antiretroviral therapy for HIV-positive women, overcoming risky sexual behaviors and practices, and advocating early detection and treatment of precancerous cervical lesions.
To assess cervical cancer screening positivity rates, follow-up rescreening uptake 1 year after treatment and persistent positivity among women with initial positive screening results in Ethiopia. The study also explored reasons for loss to follow-up and preferences for reminder strategies.
Longitudinal cross-sectional study.
10 primary healthcare facilities in Oromia and southern and central Ethiopia.
From November 2022 to April 2024, 17 586 women screened for cervical cancer. Of these 768 (4.4%) had positive screening results, and 515 women treated at the primary level were included to assess follow-up rescreening uptake. An additional 139 women who did not return for follow-up were interviewed to identify reasons for non-uptake and reminder preferences.
Of the 515 women included in the analysis, 179 (34.8%, 95% CI: 30.6% to 38.8%) returned for follow-up rescreening. Among those re-screened, the persistent visual inspection with acetic acid (VIA) positivity rate was 16.1% (95% CI: 11.0% to 21.7%). Factors significantly associated with follow-up rescreening uptake included age over 40 (adjusted OR (AOR): 2.5; 95% CI: 1.34 to 5.00), urban residence (AOR: 1.7; 95% CI: 1.15 to 2.58), secondary or higher education (AOR: 2.0; 95% CI: 1.06 to 4.12) and HIV-positive status (AOR: 2.4; 95% CI: 1.27 to 4.87). Among the 139 women contacted, the main reasons for non-uptake were lack of time, forgetting appointments, visiting another facility and pregnancy. Regarding preferred reminders, 93% favoured text messages and all agreed to phone calls or home visits.
One-third of women adhered to follow-up rescreening after a positive cervical cancer screening in Ethiopia, revealing a considerable gap since those women had a three times higher chance of being VIA positive compared with the first screening. Older age, urban residence, higher education and HIV-positive status were significantly linked to follow-up rescreening uptake. Addressing barriers such as time constraints and forgotten appointments through tailored reminder strategies is essential for improving the follow-up rescreening uptake. Contextualised interventions can strengthen rescreening for finding those women at very high risk for cervical lesions and strengthen cervical cancer prevention in Ethiopia.
