Global, regional, and national burden of intestinal obstruction from 1990 to 2019: an analysis from the Global Burden of Disease Study 2019

Background Intestinal obstruction (IO) is a common surgical acute abdominal condition that places a significant burden on modern health systems. Unfortunately, the global burden and trends of IO remain unknown. Therefore, this study aimed to comprehensively assess its long-term trends and epidemiological features, which will help policymakers to formulate appropriate health policies. Methods We conducted an ecological study using data from the Global Burden of Disease Study (GBD) 2019. Data on IO were analyzed by sex, age, year, sociodemographic index (SDI), and location according to GBD 2019. In addition, joinpoint regression analysis was used to assess temporal trends. Age-period-cohort analysis (APC Analysis) was conducted to evaluate age, period, and birth cohort effects on IO incidence and mortality risk. Results Globally, the prevalent and incident cases increased by 56.91% and 86.67% from 1990 to 2019, respectively. Joinpoint regression analysis showed that age-standardized incidence rate (ASIR) and age-standardized prevalence rate (ASPR) increased, but age-standardized mortality rate (ASMR) and age-standardized disability-adjusted life year (DALY) rate decreased over the past three decades. The age effect demonstrated that older people have a higher risk of morbidity and mortality. The period effect of incidence and mortality showed an upward trend from 1990 to 2019. Cohort effect revealed that the incidence and death risk peaked in the earlier-born cohort and was lower in the more recent-born cohort. Notably, we found that the burden of IO was higher in males than in females throughout the study period. There are huge disparities in IO burden among countries. Conclusion Globally, the reported incidence and prevalence of IO increased from 1990 to 2019. The burden of IO differed markedly by age, sex, country, and region. Middle-aged and elderly people over 50 years old were at high risk. Given the ageing population, the burden of IO will be a major public health challenge. Thus, there is a strong necessity to strengthen prevention and early intervention in the at-risk population.
