Tendencia de la mortalidad por enfermedades intersticiales en México, período 2000-2010

Background: Worldwide almost no epidemiologic data are available on the mortality of interstitial lung diseases in the general population. Its epidemiology in Mexico has not been well characterized. Objectives: We aimed to analyze the trends in mortality age-stan- dardized by interstitial lung diseases from 2000 to 2010 in Mexico and the annual death rates by age and sex. Methods: The offi cial National Database of Mortality was used to establish date and cause of deaths (Instituto Nacional de Estadistica y Geografia (INEGI) from 2000 to 2010 in Mexico. Age-standardized rates were calculated by direct method; annual rates of death by sex in two age-groups (45-64 years old and 65 or more years old) were calculated. The codes of the International Statistical Classifi cation of Diseases and Related Health Problems 10th Revision (CIE-10) J60-J80, J82-J84 y J99.1 were analyzed. Results: Of 5,420,059 deaths registered, 22,600 were diagnosed as death of an interstitial lung disease between 2000 and 2010 (0.4%). The CIE-10 code with a higher percentage of deaths was J84: «other pulmonary interstitial diseases» with 80.2% (18,127/22,600). This code includes the rheumatic diseases and autoimmune diseases that exhibit a lung interstitial disease. The age-standardized mortality rates by lung interstitial diseases shown an increasing trend during 2000-2010, but men exhibited higher rates than women; the description of annual mortality shown that the rates specifi c by age and sex were increasing in both sex but higher in male than female. The age group more affected was of 65 or more years old. Conclusions: This article shows the relevance of interstitial lung diseases as a death cause in Mexico. In the next years will be required additional resources to medical care in these diseases.
