Objective: To analyze differences of the impact of health care services, sanitation and literacy on the mortality rates of children under five years of age, in two Mexican states with marked socioeconomic differences: Chiapas and Nuevo Leon.
Material and methods: The study design was ecologic, based on a retrospective analysis of data published by the Health Ministry (Secretaría de Salud), National Institute of Statistics, Geography and Informatics (Instituto Nacional de Estadística, Geografía e Informática) and the National Population Council (Consejo Nacional de Población), on the tendencies of mortality among children under five years and on the changes of selected indicators corresponding to the period 1990-1997.
Study design: ecologic study. This was based on a retrospective analysis of data published by Secretaría de Salud, Instituto Nacional de Estadística e Informática and Consejo Nacional de Población, about the tendencies of mortality among children under five years, and about the changes of selected indicators. The analysis was carried out in the period comprised between 1990-1997. For both states the registered variations were calculated and the trends were determined through analysis of simple linear regression; the independent variable corresponded to the study years. Partial correlation analysis between the various mortality trends studies and between and the selected indicators, were calculated.
Results: During the studied period there was a steady decline of children mortality, which was more marked in Chiapas. In both entities, this decrease was closely related to the decline in mortality due to acute diarrhea, and also correlated with a descent in measles and acute respiratory infections. In Chiapas, the indicators which correlated more significantly with this decline in mortality were vaccination coverage and literacy. In Nuevo Leon, the indicators with greater correlation were the increase in the number of nurses, of lodgings with piped water and vaccination coverage.
Conclusions: During the analyzed period, the mortality rate of children under five years of age decreased in the states of Chiapas and Nuevo Leon. To sustain or accelerate the decline in childhood mortality it is mandatory to continue with the currently implemented programs, and in Chiapas, and similar states, to increase the available infrastructure to provide health care.
