  1. Data are n (%) for categoric variables and median (interquartile range) for continuous variables. Percentage and median are adjusted for survey weights of NHANES. Tertiles of sedentary time: participants with prediabetes (h/day): Tertile 1: <7.3; Tertile 2: 7.3–9.0; Tertile 3: ≥ 9.0; participants with diabetes: Tertile 1: <7.7; Tertile 2: 7.7–9.3; Tertile 3: ≥ 9.3. *P values present the difference between prediabetes and diabetes. Boldface type indicates P <0.05. Abbreviate: BMI body mass index, CVD cardiovascular disease, HbA1c glycated hemoglobin A1c, HDL-C high-density lipoprotein cholesterol, HEI healthy eating index, LPA light-intensity physical activity, MVPA moderate- to vigorous-intensity physical activity, TC total cholesterol
