Variation in life years lost from breast and cervical cancer by national marginalization index in México, 1997 to 2007
Abstract
Objective: Calculate the Years of Life Lost (YLL) for breast cancer (BC) and cervical cancer (CC) in Mexico from 1997 to 2007, by the national marginalization index. Materials and Methods: Descriptive, cross sectional and comparative study using mortality data from national vital statistics for BC and CC by five year age groups (between 20 and 79 years). To estimate the YLL, the technique proposed by Arraiga in 1996 was used, assuming no mortality in the age groups analyzed.
Data was stratified by level of marginalization, according to the National Population Council (CONAPO) in 2005. Results: A decrease in YLL for CC (0.048) and an increase for BC were observed in the decade analyzed. Women who live in areas with a high or very high marginalization index had more YLL due to CC, and women in more developed areas had the highest YLL for BC.
The middle marginalization group had the greatest decrease in YLL due to CC and the biggest increase in YLL due to BC, compared to the other two groups. Discussion: Both the observed tendencies for CC and BC and the differences according to level of marginalization resemble results obtained in other contexts in Latin America
