Abstract
Purpose
To investigate the association between Activity Sleep Index (ASI) and Metabolic Syndrome Severity (MSS) scores in a nationally representative sample of U.S. adults with diabetes.
Methods
We conducted an analysis of the 2011-12 and 2013-14 cycles of the National Health and Nutrition Examination Survey (NHANES). MSS scores were calculated using sex, systolic blood pressure, diastolic blood pressure, triglycerides, high-density lipoprotein cholesterol, blood glucose, and waist circumference. A higher MSS was indicative of worse cardiometabolic health. ASI was calculated based on average time spent in moderate-to-vigorous physical activity (MVPA), light-intensity physical activity (LIPA), sedentary behavior, and sleep derived from raw accelerometer data. Multivariable linear regression was used to assess the association between ASI and MSS.
