Physical Activity and Abdominal Fat Distribution in Greenland.

Purpose: We examined how total volume of physical activity and reallocation of time spent at various objectively measured intensities of physical activity (PA) were associated with overall and abdominal fat distribution in adult Inuit in Greenland. Methods: Data were collected as part of a countrywide cross-sectional health survey in Greenland. A combined accelerometer and heart rate monitor measured total physical activity energy expenditure (PAEE) and intensities of PA (N=1536). Visceral- and subcutaneous adipose tissue (VAT, SAT) was assessed by ultrasonography. Isotemporal substitution modeling was used to analyse the association between substitution of 1-hour of sedentary time to light or moderate intensity PA and 1-hour light intensity PA to moderate or vigorous intensity PA in relation to BMI, waist circumference (WC), SAT and VAT. Results: A negative linear association was found for total PAEE and BMI, WC, VAT and SAT. Exchanging 1-hour of sedentary time with light intensity PA was associated with lower WC (-0.6 cm., p=0.01), SAT (-0.08 cm., p
