†
All model estimates represent weighted averages by sex.
1
Demographic model adjusted for age, race, height, weight and weight0.5.
2
Dietary factors model adds total dietary calories and dietary sodium.
3
Lifestyle factors model adds smoking, alcohol use, education, and moderate-vigorous physical activity.
4
Comorbidities model adds diabetes status, systolic blood pressure, anti-hypertensive medication use, urinary albumin to creatinine ratio, C-reactive protein, and estimated glomerular filtration rate.
