Abstract
BACKGROUND: The purpose of the current study was to apply a more novel approach to systematically examine (1) associations of clustered cardiometabolic risk and cardiometabolic risk factors and (2) theoretical substitution of sedentary time with either sleep, light physical activity (LPA), or moderate to vigorous physical activity (MVPA) and substituting LPA with MVPA. METHODS: Physical activity and sleep were objectively measured in 410 Flemish adults [55.5 (9.6) y, 64% men] with a SenseWear Pro 3 Armband. Cardiometabolic risk factors (obesity, hyperglycemia, dyslipidemia, and hypertension) and cardiorespiratory fitness were objectively measured. Isotemporal substitution analyses were performed to assess the associations between substituting time from a potentially negative behavior into another potentially positive behavior. RESULTS: Theoretical substitution of sedentary time with MVPA was associated with decreased clustered cardiometabolic risk, b = -0.06 (-0.08 to -0.04), and substituting LPA with MVPA was associated with a decrease in clustered cardiometabolic risk, b = -0.08 (-0.11 to -0.04). Substituting sedentary time with LPA or sleep improved high-density lipoprotein-cholesterol, systolic and diastolic blood pressures, and waist circumference. CONCLUSION: Theoretical replacement of sedentary time with either sleep, LPA, or MVPA was positively associated with improved cardiometabolic risk factor status. Interventions for increasing cardiometabolic health can focus on replacing sedentary time with either sleep, LPA, or MVPA depending on the risk parameters that need to be targeted.
