Principal factor analysis of the risk factors and WHtR in the studied population: Caucasian prepubertal children aged 6–12 years from three cities in Spain (Cordoba, Santiago de Compostela and Zaragoza), May 2007–May 2010
| Variable | CVD risk and IR | Inflammation |
|---|---|---|
| Loading factor* | ||
| Active PAI-1 | 0·735 | |
| Resistin | 0·643 | −0·396 |
| HOMA-IR | 0·707 | |
| HDL-C | −0·648 | |
| Systolic BP | 0·531 | 0·327 |
| TNF-α | 0·773 | |
| CRP | 0·277 | 0·653 |
| Percentage | ||
| Variance | 31·90 | 19·20 |
| Cumulative variance | 31·90 | 51·10 |
WHtR, waist-to-height ratio; IR, insulin resistance; PAI-1, plasminogen activator inhibitor-1; HOMA-IR, homeostasis model assessment of insulin resistance; HDL-C, HDL-cholesterol; BP, blood pressure; CRP, C-reactive protein.
*Loading factor is the linear association between an observed variable and an underlying factor. Relative loadings: very strong (> 0·80), strong (0·60 to 0·79), moderate (0·40 to 0·59) and marginal (0·20 to 0·39).
