title: [Change in life expectancy in connection with three large groups of causes of death in Medellín, Colombia, between 1989-1991 and 1994-1996].
abstract: OBJECTIVE
  To examine changes in life expectancy in Medellin, Colombia, between 1989-1991 y 1994-1996, in connection with four large groups of causes of death commonly employed in studies on the burden of disease: group 1, communicable diseases, perinatal and maternal health problems, and nutritional deficits; group 2, non-communicable diseases; group 3, wounds; group 4, ill-defined causes. The latter were excluded from the analysis because of their ambiguity.
  
  
  METHODS
  The calculations were made according to the method described by J. H. Pollard in 1986, with the aid of Microsoft Excel, by using the recommended formulas. The computations were double checked with EPIDAT (version 3.0, unofficial).
  
  
  RESULTS
  Between 1989-1991 y 1994-1996, a total gain of 1.93 years in life expectancy was seen in Medellin, with a rise from 62.13 to 64.06 years. The gain was greater in men than in women (2.42 vs. 1.09 years, respectively). The increase noted among females was greatest in the extreme age groups (girls 1 to 4 and women over 54 years of age); in men, it was highest in the middle years (between the ages of 25 and 44). In both sexes, the greatest percentage loss in life expectancy was seen in persons 15 to 19 years of age (23% in men and 4% in women, roughly). In the group comprising communicable diseases, perinatal and maternal health problems, and nutritional deficits, a loss in life expectancy was seen in men (0.04 years), whereas in the group of non-communicable diseases there was a gain in life expectancy in both sexes (0.60 years among men and 0.55 years among women). The greater gain in life expectancy among men was linked to a reduction in mortality from wounds (1.98 years).
  
  
  CONCLUSIONS
  If one compares the results obtained in Medellin at the end of the study period with life expectancy at birth in Colombia in 1995, which was 70 years, it is obvious that life expectancy in Medellin is still lagging behind, even though it has risen progressively over the years. This is in keeping with the epidemiological transition the city has experienced, which has been linked with a rise in mortality from degenerative and cardiovascular diseases, chronic respiratory ailments, and diabetes, as well as from diseases resulting from human activity. Nevertheless, this epidemiological transition has been slow in Medellin when compared to Colombia as a whole due to high rates of death from infectious and parasitic diseases, which are more characteristic of the transition in its earlier stages. Despite the fact that mortality from wounds has decreased in Medellin, particularly among young males, it may be worthwhile to reassess the effectiveness of interventions undertaken in recent years to promote peaceful coexistence and tolerance in the community.
