Changes in UAE Associated with Decreases in Waist Circumference and Dietary Measures

	Individual Models		Multivariable Model 1		Multivariable Model 2		Multivariable Model 3
Decrease	ΔUAE (95% CI)	p-value	ΔUAE (95% CI)	p-value	ΔUAE (95% CI)	p-value	ΔUAE (95% CI)	p-value
Waist circumference (per 6.6 cm)	−10.9 (−16.6 to −5.2)	0.001	−9.9 (−15.6 to −3.8)	0.002	−9.9 (−15.4 to −3.8)	0.002	−10.6 (−16.3 to −4.6)	0.001
24-h urine P (per 314.1 mg/d)	−10.9 (−16.4 to −4.9)	<0.001	−8.2 (−15.2 to −0.6)	0.03	−9.8 (−15.4 to −3.8)	0.002
Protein intake (per 19.4 g/d)	−8.1 (−13.9 to −2.0)	0.01	−2.9 (−10.3 to 5.0)	0.5			−7.7 (−13.4 to −1.5)	0.02
24-h urine Na (per 71.7 mmol/d)	−4.7 (−10.7 to 1.7)	0.1
24-h urine K (per 27.8 mmol/d)	−2.3 (−8.5 to 4.4)	0.5
Na/K ratio (per 1.3 mmol/mmol)	−1.5 (−7.8 to 5.1)	0.6

Note: N=481. Each model was adjusted for age, site, African-American race, current smoking, baseline systolic blood pressure and ln(UAE). Covariates were standardized in these models to facilitate relative comparisons between regression coefficients. Beta coefficients were then back-transformed and are presented as percent change in UAE associated with a one standard deviation decrease in the corresponding predictor variable.

Abbreviations and definitions: urinary albumin excretion (UAE), phosphorus (P), sodium (Na), potassium (K); CI, confidence interval, ΔUAE, change in UAE.
