Note: Means represent adjusted means of the dependent variables in each albuminuria category. The means in models 1 were adjusted for age, sex, glucose metabolism status, waking time, educational level, smoking behavior, alcohol consumption, energy intake, comorbid disease, mobility limitation; in models 2 the means of the sedentary behavior variables were additionally adjusted for HPA; in models 3, the means of HPA and the sedentary behavior pattern variables were additionally adjusted for sedentary time; in models 4 all means were additionally adjusted for office systolic blood pressure, use of antihypertensive medication, waist circumference, total-to-HDL cholesterol ratio, triglycerides, use of lipid-modifying medication, prevalent cardiovascular disease.
All analyses were based on complete cases (n = 2,258).
Abbreviations: CI, confidence interval; eGFRcrcys, estimated glomerular filtration rate based on serum creatinine and serum cystatin C; HPA, higher intensity physical activity; HDL cholesterol, high-density lipoprotein cholesterol; N/A, not applicable.
