Prostate cancer mortality according to marginalization status in Mexican states from 1980 to 2013

Abstract

Objective.To assess prostate cancer (PC) mortality in Mexico from 1980 to 2013, according to the state marginalization level. Materials and methods. Using age-adjusted rates in men ≥ 40 years old, we estimated trends and agecohort-period effects of PC mortality from 1980-2013 according to state marginalization status by using a joinpoint regression model and a Poisson regression model proposed by Holford. Results. The PC mortality risk has increased nationwide at a constant rate (2% annually) during the past 13 years. The highest annual increase was observed among states with very high (4.4%) and high (7.7%) marginalization rates. In contrast, states with very low levels of marginaliza- tion showed a significant reduction of 1.5% per year. The main changes were observed in the 1945-1950 birth year cohorts. Conclusions. Differences in PC mortality across regions of Mexico may reflect differences in the timing of the diagnosis and treatment of PC. DOI: http://dx.doi.org/10.21149/spm.v58i2.7787
