Abstract

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.
