Adherence to dietary recommendations and the risk of developing giant cell arteritis: A nested Case-Control study
Main finding · Development of GCAResult — go to the resultAdjusted odds ratio 2.70 95% CI 1.43–5.10Authors' conclusion
An overall high diet quality was independently associated with an increased risk of GCA.
Study context
- Population
- Participants in the Malmö Diet and Cancer Study cohort who subsequently developed giant cell arteritis (GCA), with matched controls193 incident GCA cases
- Comparison
- High vs low adherence to dietary guidelines
- Outcome
- Development of GCA
Methodological details4 controls per case, matched for age, sex and year of inclusion, logistic regression adjusted for total energy intake, leisure-time physical activity and alcohol intake, potential misreporters of total energy intake excluded

Further findings
Adherence to individual recommendations and GCA risk (adjusted)
- Adherence to recommended intake of added sugar, fish and shellfish, and vegetables and fruit associated with increased GCA risk
Quantified intake of components and GCA risk
- Reduced risk with higher added sugar consumption
- Increased risk with higher intakes of fiber and fish and shellfish
