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 marginalization 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.
