Multivariate adjustments include age, sex, BMI, diabetes duration, current smoking habit, current alcohol intake, LTPA, sleep duration, HbA1c, UACR, systolic blood pressure, LDL cholesterol, history of CVD and cancer.
BMI, body mass index; CVD, cardiovascular disease; HbA1c, hemoglobin A1c; LDL, low-density lipoprotein; LTPA, leisure-time physical activity; UACR, urinary albumin creatinine ratio.
