Objective: To discuss trends of cervical cancer mortality in the State of Paraná, Brazil, from 1980 to 2000, as related to indices of socioeconomic status in each region of the State. Methods. The official System for information on Mortality supplied data on cervical cancer deaths, as stratified by age and town of residence. Age-adjusted death rates were calculated for 22 regions of the state in each year. The assessment of trends used the Cochrane-Orcutt procedure of autoregression for time-series analysis and estimation of the annual percent increase of mortality. Primary information on population and intercensal estimates were gathered from general censuses performed in 1980, 1991 and 2000. Socioeconomic data at the region level refer to the census of 2000, the most recent source of socioeconomic information. Regions presenting stationary and increasing trend of cervical cancer mortality were compared as to socioeconomic indices. Results. Cervical cancer deaths were on increase in the state of Paraná, with an annual percent increase of 1.68% (1.20 to 2.17, 95% confidence interval). Despite the overall increase of rates, most regions presented leveled-off rates. The comparison of regions presenting increasing and stationary trend indicated poorer socioeconomic indices for the former set: regions with increasing cervical cancer mortality had significantly higher illiteracy rate (p<0.001), percent of individuals older than 15 years with less than 4 years of study (p=0.001), and lower per-capita income (p=0.025) and human development index (p=0.023). Conclusion. Increasing mortality trend was observed; areas with higher death rates presented worse indices of socioeconomic status.Key words: cervical cancer / epidemiology; mortality / cancer; statistics models / trends.
