Impacto de la morbilidad en la salud de la población del País Vasco 2002-2007: una visión integral a través de las esperanzas de salud

background: the estimation of the impact of morbidity on health is essential to health planning. the objective was to estimate this impact using disability free life expectancy, and to analyze whether the hypothetical elimination of various diseases would have led to a compression or expansion of morbidity. methods: cross-sectional study on the population of the basque country. data on mortality (2002-2006), health survey data (2007) and population based data were used. the impact of different groups of diseases on mortality rates, years of life and potential years of life lost (pyll) and disability (absolute number and rates) were calculated. an integrated analysis was also done, using disability free life expectancy (dfle), using the sullivan method. results: the diseases causing the greatest impact on mortality were tumours among men (35,2% and 39,3% of deaths and pyll respectively), and circulatory diseases (34,5% of deaths) and tumours (43,6% of pyll) among women. osteomuscular diseases had a major impact on disability, causing the 26,6% and the 45,2% of the total cases in men and women). circulatory diseases had the highest impact as a whole (4.2 years of dfle in men and 3.8 in women). however, osteomuscular diseases had the highest influence on years of life with disability. conclusions: the diseases which caused the overall greatest impact on mortality and disability were circulatory system related ones, tumors, and osteomuscular diseases. the elimination of this last group of diseases would have led to a morbidity compression, meaning the greatest reduction in life years with disability among all the causes.
