A principal factor analysis is selected with four factors retained and an oblique promax rotation used. Significance is highlighted in bold text and is determined by a factor loading >0.3. The significant loadings suggest a blood pressure factor (factor 3) and a lipid factor (factor 4). Factor 1 and factor 2 demonstrate some overlap with PCIns loading significantly on each. Abbreviation: Fasting insulin (Ins), postchallenge insulin (PCIns), fasting glucose (Glu), postchallenge glucose (PCGlu), body mass index (BMI), waist/hip ratio (WHR), high density lipoprotein cholesterol (HDL), triglycerides (Trig), systolic blood pressure (SBP), diastolic blood pressure (DBP).
