Abstract

BACKGROUND Gastrointestinal and liver diseases (GILD) constitute a noteworthy portion of causes of death and disability in Iran. However, data on their prevalence and burden is sparse in Iran. The Global Burden of Disease (GBD) study in 2010 has provided invaluable comprehensive data on the burden of GILD in Iran. METHODS Estimations of death, years of life lost due to premature death (YLL), years of life lost due to disability (YLD), disability-adjusted life years (DALY), life expectancy, and healthy life expectancy have been reported for 291 diseases, 67 risk factors, 1160 sequelae, for both sexes and 19 age groups, form 1990 to 2010 for 187 countries. In the current paper, 5 major categories of gastrointestinal (GI) and liver diseases have been investigated as follows: GI infectious diseases, GI and liver cancers, liver infections, chronic end stage liver disease, and other digestive diseases. RESULTS Among women, 7.6% of all deaths and 3.9% of all DALYs were due to digestive and liver diseases in 2010. The respective figures in men were 7.8% of deaths and 4.6% of DALYs. The most important cause of death among children under 5 is diarrhea. Among adults between 15 to 49 years old, the main causes of death are GI and liver cancers and cirrhosis, while diarrhea still remains a major cause of DALY. Among adults 50 years and above, GI and liver cancers and cirrhosis are the main causes of both deaths and DALYs. Gastritis and duodenitis, diarrheal diseases, gall bladder and bile duct diseases, acute hepatitis A, peptic ulcer disease, appendicitis, and acute hepatitis A mainly cause disability rather than death. CONCLUSION GBD study provides invaluable source of data on burden of GILD in Iran. However, there exist limitations, namely overestimation of burden of liver cancer and underestimation of the burden of GI diseases that are usually diagnosed in outpatient settings. The collaboration of scientists across the world and specifically those from developing countries is necessary for improving the accuracy of future updates of GBD in these countries.
