[Deaths by homicide in Mexico: trends, socio-geographical variations and associated factors].

This study seeks to analyze the trend of homicide rates (total and by firearm) in Mexico between 1990 and 2009 and identify the variables that best explain the geographical variations of these rates in the 2008-2009 two-year period. Homicide rates, adjusted for age, were calculated for both sexes between 1990 and 2009 and for each state in 2008-2009. Factors associated with the interstate variations in the homicide rates were identified using multiple linear regression analysis.

[Demographic characteristics, social inequality and inequity in Mexican childhood health].

Objectives: Demographically describing the present and future for Mexican children to correlate aspects regarding demographic and social equity during childhood and describing the challenges these variables represent for Mexican children during the next few years.

Methods: The present and future scenario for Mexican childhood was evaluated using existing population projections. Mortality rates were estimated from avoidable causes during childhood per Mexican state, per state grouped by quartile depending on their marginalisation level and by municipality grouped according to their degree of marginalisation.

[A socio-spatial analysis of social exclusion and inequity in health in Mexico].

Objective: Determining the relationship between social exclusion and health inequity at state and municipal level in Mexico during recent years.

Methods: Adjusted mortality rates were calculated for 2005 (related to transmissible illnesses in childhood, pregnancy, childbirth and being produced by causes considered potentially avoidable); rates were calculated by states, for states grouped in quartiles according to marginalization level and for municipalities grouped according to degree of marginalization. Indicators such as rate ratio, Gini coefficient and the inequities in health index (IHI) were used for measuring such inequity.
