  • IBD Fundamentals

    In this module, we will explore key aspects of IBD, including its definition and epidemiology as well as diagnosis, treatment, health maintenance, and preventative care. Additionally, we will highlight the crucial role of patient-provider partnerships, shared decision-making, approaches to patient education and empowerment, and efforts to address social determinants of health (SDOH) and racial disparities in IBD care.

      Epidemiological stages of IBD evolution1

      Stage 1

      Emergence

      What:
      Sporadic cases begin to appear

      Where:
      Developing countries

      Stage 2

      Accelerating Incidence

      What:
      Incidence increases, but prevalence remains low

      Where:
      Newly industrialized countries

       
       

      Stage 3

      Compounding Prevalence

      What:
      Incidence stabilizes, but prevalence rises sharply

      Where:
      Western nations

      Stage 4

      Prevalence Equilibrium

      What:
      Growth in prevalence levels off as incidence is offset by an aging IBD population

      Where:
      Predicted to begin in Western nations ~ year 2050

    • Annual incidence and prevalence rates of IBD in adults* by geographical region†2

      Incidence: Defined as the number of adult cases per 100,000 adult years.

      Prevalence: Defined as the number of cases in a region per 100,000 adults at a given time.

      Infographic showing global incidence and prevalence rates per 100,000 people, displayed on a stylized globe with statistics connected to each region by thin lines. Green pill-shaped labels show incidence per 100K: North America 7.3–30.2, Europe 10.5–46.1, Asia/Middle East 1.4–1.5, South America 0.2–3.7, Oceania 23.7–39.8. Teal pill-shaped labels show prevalence per 100K: North America 214.9–478.4, Europe 187–832, South America 1.8–70.1. Asia/Middle East and Oceania display only incidence data.

      Prevalence data from Asia/Middle East and Oceania are unavailable.
      *Adults aged 18 to 59 years of age.
      This data was compiled using key epidemiological studies published between 2006 and 2023.

      Answer

      ~2.4M3
      (~1.3M=UC, ~1.0M=CD)

      Estimated based on extrapolated population data.

      Question

      What’s the prevalence of IBD by race?

      Answer

      1.6M
      Non-Hispanic White3
      224K
      Black3
      281K

      79K
      Asian3

      Estimated based on US population size of ~331 million.

      Question

      Has IBD been on the rise?

      Answer

      From 2007 to 2016 Prevalence Increased
      ↑123%
      for adult IBD overall
      ↑142%
      for adult UC
      ↑125%
      for adult CD

      Based on a meta-analysis of data from over 26M adult patients (age ≥18) with continuous coverage (year 2007 through 2016) from 2 large, geographically diverse administrative health claims databases across all 50 US states.4

      Question
