Osteochondrodysplasias are a heterogeneous group of more than 200 entities, characterized by abnormalities of cartilage, bone growth, and skeletal development. The aim of this study was to assess temporal and spatial changes in overall mortality due to these disorders in Spain, using data from a nationwide registry. Annual deaths showing osteochondrodysplasias as the underlying cause of death were selected using the International Classification of Diseases‐9th revision (ICD‐9) codes for the period 1981 through 1998, and ICD‐10 codes for the period 1999 through 2008. Age‐adjusted mortality rates were calculated by sex, and geographic analysis was performed by municipality. A total of 679 deaths were recorded (53% men). Age‐adjusted mortality rates went from 0.09 (0.06, 0.12) per 100,000 population in 1981 to 0.05 (0.03, 0.08) per 100,000 population in 2008. A changing trend in the age‐standardized mortality rate was in evidence, with an annual increase of 2.4% (−0.4, 5.2) from 1981 to 1994, and an annual decrease of −7.3% (−10.9, −3.5) from 1995 onwards. Geographic analysis showed some places situated in the west and south of Spain with greater risk of mortality. There is a need to identify risk factors and to increase overall knowledge about the life expectancy and epidemiology of osteochondrodysplasias. (c) 2013 Wiley Periodicals, Inc.
