Self-Reported Cervical Cancer Screening Uptake Among Women of Reproductive Age in Zambia: Evidence from the 2021 Zambia Population-Based HIV Impact Assessment (ZAMPHIA) Survey

Background Despite Zambia implementing the World Health Organisation's (WHO) tri-pillar cervical cancer prevention goals 90-70-90 Prevent, Screen, and Treat, cervical cancer claims 2000 lives annually and reigns as the most common cancer among women, especially those living with HIV (WLHIV). Our study describes the national uptake of screening and treatment from the ZAMPHIA 2021 survey. Methods Utilising a two-stage cluster sampling approach, the study included participants aged 15 years and older across Zambia’s ten provinces. Data were collected on demographic traits, reproductive history, sexual behaviour, and cervical cancer prevention using a structured questionnaire, and HIV was diagnosed from biological samples. Women aged 15-49 were eligible for inclusion in the analysis. The primary outcome of interest was whether a woman self-reported being screened for cervical cancer. Sociodemographic characteristics were calculated for categorical variables using the SAS proc surveyfreq procedure, producing both raw and weighted estimates. The weighted estimates and their variance were generated using jackknife replicate weights for each record. Results Of the 8801 surveyed women, 22.2% reported undergoing cervical cancer screening, the majority being aged between 35-49 years. Cervical cancer screening uptake was more likely among compared to HIV negative counterparts (aOR = 3.92, 95% CI: 3.10, 4.95), those aged 25-34 years (aOR = 1.76, 95% CI: 1.42, 2.21) or 35-49 years (aOR = 2.65, 95% CI: 2.11, 3.33) than younger and those with 1-4 (aOR = 2.16, 95% CI: 1.54, 3.02) or more than 5 live births (aOR = 1.98, 95% CI: 1.37, 2.87) than none. Marital status, WLHIV, education, and parity were other factors significantly associated with screening. Conclusion We report low cervical cancer screening uptake compared to the 70% target of WHO. The WHO’s call for bolstered strategies and efforts to increase cervical cancer screening and treatment is timely and urgent. Therefore, ongoing messaging and health education among all women is key.

Implementation strategies to increase human papillomavirus vaccination uptake for adolescent girls in sub-Saharan Africa: A scoping review protocol

Introduction The human papillomavirus (HPV) is sexually transmitted and infects approximately 75% of sexually active people early in their sexual life. Persistent infection with oncogenic HPV types can lead to malignant conditions such as cervical cancer. In 2006, the World Health Organisation approved the use of an efficacious HPV vaccine for girls aged 9 to 14 to prevent HPV-related conditions. Despite the HPV vaccine being available for about 15 years, dose completion remains as low as 20% in sub-Saharan African (SSA) countries implementing the vaccination program compared to 77% in Australia and New Zealand. A fraught of barriers to implementation exist which prevent adequate coverage. Achieving success for HPV vaccination in real-world settings requires strategies to overcome implementation bottlenecks. Therefore, a better understanding and mapping of the implementation strategies used in sub-Saharan Africa to increase HPV vaccination uptake is critical. This review aims to identify implementation strategies to increase HPV vaccination uptake for adolescent girls in sub-Saharan Africa and provide a basis for policy and future research, including systematic reviews to evaluate effective strategies as we accelerate the elimination of cervical cancer. Materials and methods This scoping review will consider studies pertaining to implementation strategies to increase HPV vaccination uptake for adolescent girls in sub-Saharan Africa. Studies targeted at different stakeholders to increase adolescent vaccine uptake will be included. Studies using interventions not fitting the definition of implementation strategies as defined by the refined compilation of implementation strategies from the Expert Recommendations for Implementing Change project will be excluded. MEDLINE (via PubMed), Embase, CINAHL (via EBSCO), Scopus and Google Scholar will be searched. Two independent reviewers will screen titles and abstracts for studies that meet the review’s inclusion criteria, and the full text of eligible studies will be reviewed. Data will be extracted from eligible studies using a structured data charting table developed by this team for inclusion by two independent reviewers and presented in a table and graphical form with a narrative summary.
