Prevention & lipidsCohort study

Polygenic risk score, dietary inflammatory potential, and incident coronary heart disease

Eur J Prev CardiolPublished

  • Prospective cohort study
  • UK Biobank

Empirical dietary inflammatory pattern (EDIP) score by reduced rank regression and stepwise linear regression; Polygenic risk score (PRS) from 1.7 million genetic variants

Authors' conclusion

High dietary inflammatory potential was associated with a higher CHD risk, especially in those with high PRS

Study context

Population
British UK Biobank participants who completed the 24-h dietary assessment at baseline1,346 incident coronary heart disease (CHD) cases
Participants
51,889 participants
Exposure
High vs low dietary inflammatory potential and PRS for CHD, jointly
Outcome
Incident CHD
Follow-up
Median 11 years

Main finding

Incident CHD, joint effect of PRS and EDIP

Hazard ratio

3.87

95% CI 2.74–5.46

High PRS (Q5) + high EDIP (T3) vs Low PRS (Q1) + low EDIP (T1)
HR 3.87 (95% CI 2.74–5.46)

As reported in the abstract

Observational data: associations, not effects.
