Abstract
- Background: Hemoglobinopathies are known as the most common genetic disorders in Iran. The paper aims to provide global estimates of deaths and disability adjusted life years (DALYs) due to hemoglobinopathies in Iran by sex and age during 1990 to 2010 and describe the challenges due to limitations of the Global Burden of Diseas study 2010 (the GBD study 2010). Methods: The GBD study 2010 estimates of the numbers of deaths and years of life lost (YLLs) due to premature mortality were calculated using the Cause of Death Ensemble model (CODEm). Years of life lost due to disability (YLDs) were computed by multiplication of prevalence, the disability weight for occurrence of sequelae, and the duration of symptoms. Prevalence was estimated through a systematic search of published and available unpublished data sources, with a Bayesian meta-regression model developed for GBD study 2010. Disability weights were produced using collected data from population-based surveys. Uncertainty from all inputs was incorporated into the computations of DALYs using simulation methods. We aim to prepare and criticize the results of the GBD study 2010 and provide some recommendations for reaching better conclusions about the burden of hemoglobinopathies in Iran. Results: Between 1990 and 2010, the overall deaths attributed to hemoglobinopathies decreased from 0.51% to 0.36% of total deaths, with the corresponding burden declining from 1 % to 0.82% of total DALYs. There was a reduction in deaths and DALYs rates for all ages and the rates attributed to all ages followed the same pattern in Iranian men and women. The highest DALYs for hemoglobinopathies, thalassemia, sickle cell disorder, and glucose-6-phosphate dehydrogenase deficiency (G6PD-D) were found in those aged less than 5 years. The collective burden of all of these hemoglobin disorder was lower in 2010 than in 1990. Conclusion: Although the screening programs in Iran have been very successful in reducing the number of thalassemia patients between 1990 to 2010, in order to provide a better estimation of the burden of hemoglobin disorders, it is necessary to perform a national and sub-national study of hemoglobinopathies using multiple national and sub-national surveys.
