Inflammatory Bowel Disease in Indigenous Populations: A Scoping Review

Area of Science:

• Gastroenterology
• Public Health
• Health Equity

Background:

• Global inflammatory bowel disease (IBD) incidence is increasing.
• Indigenous populations are underrepresented in IBD research.
• Socioeconomic factors present unique healthcare challenges for Indigenous peoples.

Purpose of the Study:

• To synthesize existing literature on IBD in global Indigenous populations.
• To identify critical research gaps concerning IBD in these communities.
• To propose recommendations for enhancing research inclusivity.

Main Methods:

• Comprehensive literature search across 8 databases (e.g., MEDLINE, EMBASE).
• Inclusion of diverse study types (qualitative, quantitative, mixed-methods, commentaries).
• Critical appraisal and synthesis of 18 selected publications since 1962.

Main Results:

• Limited research originates primarily from Canada, New Zealand, and Australia.
• Indigenous populations generally show lower IBD rates, but recent increases are noted.
• Barriers to healthcare access and minimal Indigenous engagement in research were identified.

Conclusions:

• Significant gaps exist in understanding IBD among Indigenous populations.
• Rising IBD rates in Indigenous communities warrant further investigation into genetic and environmental factors.
• Inclusion of Indigenous peoples as research partners and adherence to Indigenous research methodologies are crucial.
