Association of cervical and breast cancer mortality with socioeconomic indicators and availability of health services

Analyze cervical and breast cancer mortality in Brazil and its relationship with socioeconomic population indicators and availability of health services in the period 2011-2015. An ecological study is presented herein. Mortality data were extracted from the Mortality Information System, based on ICD-10, per area of residence and age group, for the period 2011-2015. Socioeconomic variables were extracted from the Brazilian Human Development Atlas, and the National Register of Health Facilities (CNES) provided data on the density of physicians and health services. Statistical analysis was carried out using the Chi-squared test and Poisson regression, with robust variance and 95 % confidence level. The median age-standardized mortality rates for cervical and breast cancers were, respectively, 5.95 (± 3.97) and 10.65 (± 3.12) per 100,000 women. High cervical cancer mortality rates presented a statistically significant association with GINI Index (p=0.000) and Human Development Index - HDI (p=0.030). High breast cancer mortality rates were positively associated with the variables "number of general physicians per 100,000 inhabitants" (p = 0.005) and "Number of licensed oncology centers per 1,000,000 inhabitants" (p = 0.002). The importance of organization and equity in the access to health services is highlighted herein, enabling the reorientation of public policies aimed at the minimization of health disparities.

Inequalities in Temporal Effects on Cervical Cancer Mortality in States in Different Geographic Regions of Brazil: An Ecological Study

Cervical cancer is a public health issue with high disease burden and mortality in Brazil. The objectives of the present study were, firstly, to analyze age, period, and cohort effects on cervical cancer mortality in women 20 years old or older from 1980 to 2019 in the North, South, and Southeast Regions of Brazil; and secondly, to evaluate whether the implementation of a national screening program and the expansion of access to public health services impacted the examined period and reduced the risk of death compared with previous years and among younger cohorts. The effects were estimated by applying Poisson regression models with estimable functions. The highest mortality rate per 100,000 women was found in Amazonas (24.13), and the lowest in São Paulo (10.56). A positive gradient was obtained for death rates as women’s age increased. The states in the most developed regions (South and Southeast) showed a reduction in the risk of death in the period that followed the implementation of the screening program and in the cohort from the 1960s onwards. The North Region showed a decreased risk of death only in Amapá (2000–2004) and Tocantins (1995–2004; 2010–2019). The findings indicate that health inequities remain in Brazil and suggest that the health system has limitations in terms of decreasing mortality associated with this type of cancer in regions of lower socioeconomic development.
