Abstract

Background The epidemiology of inflammatory bowel disease (IBD) has changed rapidly in recent years. Objective data concerning the IBD burden in the Middle East and North Africa (MENA) region is limited. We aimed to provide a systematic report on the IBD burden in the MENA region. Additionally, we aimed to study the age- and sex-specific trends in IBD incidence, prevalence and mortality rates from 1990-2019.

Methods Using the Global Burden of Disease (GBD) 2019 Study Database, we investigated the changes in incidence, prevalence and mortality rate, and disability-adjusted life-years (DALYs), at a regional and country level between 1990 and 2019.

Results In 2019, there were 282,534 cases (95% confidence interval [CI] 239,506-334,478) of IBD in the MENA region (50.5% male). There was an overall increase in the incidence and prevalence rates of IBD in the MENA region from 1990 to 2019, while a simultaneous decrease in overall mortality rates was identified. Incidence rates were highest in Jordan, at 6.9 (95%CI 5.8-8.1) per 100,000, and lowest in Morocco, at 1.6 (95%CI 1.4-2) per 100,000. From 1990-2019, the incidence was found increased in males at a higher rate than in females. The age-standardized mortality rate decreased for both sexes by 24% from 1990-2019.

Conclusion The trends and geographic variations in IBD within the MENA region provide policymakers with vital information for making informed decisions in policy, research, and investment, thereby enabling the development of more effective strategies and better allocation of resources.
