Abstract
Background and Objectives: Burden of cervical cancer in Central and Eastern Europe is higher than in other parts of Europe. We analyzed cervical cancer epidemiology in Serbia and Bosnia and Herzegovina (the Federation of Bosnia and Herzegovina and the Republic of Srpska) from January 2016 to December 2020, exploring the role of available sociodemographic factors and healthcare service parameters on incidence and mortality rates, using an ecological approach based on aggregated data. Materials and Methods: Incidence and mortality rates are standardized using the method of direct standardization with the World-ASR-W. Administrative units are grouped by tertiles of incidence and mortality to explore sociodemographic factors and healthcare parameters across these groups. Results: Average age-standardized incidence rates of cervical cancer per 100,000 females were 19.28 in Serbia, 12.48 in the Federation of Bosnia and Herzegovina, and 22.44 in the Republic of Srpska. Mortality rates per 100,000 females were 6.67, 5.22, and 4.56 in Serbia, the Federation of Bosnia and Herzegovina, and the Republic of Srpska, respectively. Several parameters of sociodemographics and health service usage differed significantly across units grouped by tertiles based on incidence level, i.e., female population ≥ 15 years old (p = 0.028), population density (p = 0.046), percent of gynecologists in the primary healthcare (p = 0.041), number of gynecologists per 10,000 females ≥ 15 years (p = 0.007), and the area-to-gynecologist ratio (p = 0.010). A moderate negative correlation was found between incidence and population density (rho = -0.465, p = 0.017), and a moderate positive correlation between incidence and area-to-gynecologist ratio (rho = 0.534, p = 0.005). Conclusions: Cervical cancer remains a leading cause of cancer among women in developing countries. Implementing tailored activities, such as educational programs, preventive services, and investments in healthcare infrastructure, particularly at the administrative units' level, can help in reducing health disparities and improving health outcomes.
