Burden of inflammatory bowel disease among elderly, 1990-2019: A systematic analysis based on the global burden of disease study 2019.

AIM

The number of elderly patients with inflammatory bowel disease (IBD) has increased dramatically over the past few decades. Understanding the global burden of IBD in the elderly can provide a valuable basis for formulating future healthcare policies. This study aimed to comprehensively assess the global burden of IBD in the elderly from 1990 to 2019.

METHODS

We extracted prevalence, incidence, disability-adjusted life-years (DALYs), and mortality data of older adults (60-89 years old) with IBD from 2010 to 2019 from the Global Burden of Disease (GBD) Study 2019, and analyzed in subgroups according to region, country, Socio-demographic Index (SDI), age group, and gender. Additionally, Trends in the global burden of IBD in old age from 1990 to 2019 were analyzed by calculating the estimated annual percentage change (EAPC) in the age-standardized rates (ASDs).

RESULTS

From 1990 to 2019, the number of prevalent cases, incident cases, DALYs, and deaths of IBD in older adults increased significantly. Age-standardized rates of incidence, prevalence, DALYs, and mortality all trended downward. Americas, European regions, and high SDI countries had consistently high burdens. Middle SDI countries had the fastest growth in prevalence, incidence, and the fastest decline in DALYs, and mortality. The age-standardized rates of prevalence, incidence, and DALYs for IBD in the elderly were highest in the 60-64 age group, and age-standardized rates of mortality were highest in the 80-84 and 85-89 age groups. No gender differences were observed when stratified by gender.

CONCLUSIONS

IBD in older adults has become a global public health burden due to significant increases in the number of prevalent cases, incident cases, DALYs, and deaths. There are marked differences among regions, countries, and between different age groups. Public health practitioners should develop targeted policies to effectively reduce the disease burden of IBD in older adults.
