High resolution lipoprotein subfraction profiling identifies obesity associated distributional changes in LDL and HDL subfractions and particle ratios
Authors' conclusion
The pattern of lipoprotein subfraction redistribution in participants with obesity was consistent across cohorts. These subfractional changes offer enhanced resolution compared with conventional lipid and lipoprotein measures
Study context
- Population
- Australian cohort stratified by Body Mass Index (BMI); key BMI-associated ratios validated in a second Australian cohort (n = 1313)validation cohort n = 1313
- Participants

- Exposure
- Obese vs overweight vs healthy weight
- Outcome
- Lipoprotein subfraction profile (112 parameters) by BMI
Methodological detailspopulation-level, 1H NMR spectroscopy, validation cohort

Inverse association of BMI with LDL1-3:LDL4-6, LDL2:LDL5 and HDL1:HDL4 ratios; discriminatory power for obesity status (AUROCs)
0.70-0.74
Observational data: associations, not effects.
