[Liver cirrhosis mortality in Mexico. II. Excess mortality and pulque consumption].
Over the years high cirrhosis mortality rates have been reported in Mexico City and in the surrounding states (Hidalgo, Tlaxcala, Puebla and the State of Mexico); on the contrary, well defined areas, such as the northern states, have shown a considerably lower mortality rate. This situation may indicate that some factors such as the pattern of alcoholic intake and other environmental characteristics could explain this striking difference. To determine the role of alcohol, the availability and consumption of alcohol at regional and state level were compared with cirrhosis mortality rates. A high and statistically significant correlation was found with pulque availability and consumption (r = 72-92%, p less than 0.01) in all periods of time under examination. On the contrary, a statistically significant negative association was observed with beer consumption and a positive, but not significant correlation, with distilled alcoholic beverages. Infectious hepatitis incidence, prevalence of exclusive use of native languages (as an indirect index of ethnic background) and nutritional deficiencies were also studied as possible risk factors. Nutritional deficiencies and the prevalence of exclusive use of náhuatl and otomí languages were positively correlated. These results can be useful to conduct further epidemiological studies still needed to determine the etiologic role of pulque consumption as well as of the other risk factors. Nonetheless, the current data stress the need to implement public health programs to reduce alcohol consumption, especially pulque, and to minimize the impact of these risk factors in high mortality areas.
