摘要

This study aimed to evaluate the global burden of inflammatory bowel disease (IBD) among women of reproductive age (15–49 years) from 1990 to 2021, analyze its association with socio-demographic index (SDI), and identify age-period-cohort (APC) effects to inform region-specific public health strategies. Using data from the Global Burden of Disease (GBD) 2021 study, we assessed age-standardized incidence (ASIR), prevalence (ASPR), mortality (ASMR), and disability-adjusted life years (ASDR) across 204 countries. Statistical analyses included Pearson correlation to evaluate SDI associations, decomposition analysis to quantify burden drivers, and APC modeling to disentangle age, period, and cohort effects. In 2021, the global ASIR, ASPR, ASMR, and ASDR for IBD in women of reproductive age were 4.38, 45.90, 0.50, and 17.75 per 100,000, respectively. The health burden of IBD in women of reproductive age varies by region. Australasia has the highest ASIR and ASPR globally, while these metrics are lowest in Central Latin America. Western Europe exhibits the highest ASMR, whereas Oceania has the lowest. In terms of ASDR North America, with its higher income, bears the heaviest burden, while Oceania experiences the lightest. Furthermore, APC analysis revealed age-specific risks peaking at 45–49 years, and significant cohort effects in middle/low-SDI regions, where post-1977 birth cohorts showed elevated incidence. Period effects highlighted diverging trends: stable incidence in high-SDI regions vs. rising rates in mid-SDI regions due to urbanization and lifestyle shifts. The IBD burden among reproductive-aged women is rising disproportionately, shaped by SDI gradients and demographic transitions. High-SDI regions require strategies targeting aging populations and comorbidities, while low/middle-SDI regions need investments in early diagnosis and equitable care.
