^alogarithmically transformed intra-abdominal adipose tissue area in cm² (log IAT).

*Model 1 was adjusted for risk groups (ethnicity, menopausal status), income, age and percent body fat.

**Model 2 was adjusted the same as Model 1 plus low physical activity (Kaiser Physical Activity Survey score) and smoking status.

***Model 3 was adjusted the same as Model 2 plus energy intake^∗ethnicity interaction.
