Analyses of potential causal contributors to increased waist/hip ratio‐associated cardiometabolic disease: A combined and sex‐stratified Mendelian randomization study

Diabetes Obes MetabPublished Mendelian randomization study

Authors' conclusion

MR suggests WHR increases the risk of CMD independent of these mediators, with the exception of dyslipidaemia in males, which is largely driven by the monounsaturated fatty acid to total free fatty acid ratio.

Study context

Population
European ancestries; summary statistics from the largest genome-wide association studies
Comparison
Genetically predicted increased waist/hip ratio (WHR), with and without adjustment for postulated mediators
Outcome
Effect of increased WHR on cardiometabolic traits (sex-combined Mendelian randomization (MR))
Methodological detailssex-combined and sex-stratified, summary statistics from genome-wide association studies in European ancestries
  • Sex-combined and sex-stratified
  • Summary statistics from genome-wide association studies in European ancestries

Further findings

Adjustment for mediators (sex-combined and females)

Adjustment for the mediators attenuated WHR's effects, but associations remained significant, with concordant results in females

Males: effect of WHR after adjustment for monounsaturated fatty acid to total free fatty acid ratio

HDL-C, beta (SE 0.069; p = .09)
−0.117
TG, beta (SE 0.068; p = .459)
0.051
  • WHR effect no longer significant
