To determine the relationship between sedentary behavior (SB), physical activity (PA), and body fat (total, abdominal) or body size (body mass index, BMI; waist circumference, WC) in community dwelling adults 50y and older. This study included 232 ambulatory adults (50-87 y, 37.4±9.6% body fat). Average daily time spent in SB (<100 cts/min), light (100-759 cts/min), lifestyle-moderate (760-1951 cts/min), walking-moderate (1952-5724cts/min), and vigorous-intensity (≥5725 cts/min) PA were determined by accelerometer and corrected for wear time. Body fat (BF) was measured with dual-energy x-ray absorptiometry. SB was positively related to measures of BF. Measures of SB, PA, and gender accounted for 55.6% of the variance in total BF, 32.4% of the variance in abdominal fat and 28.0% the variance in WC. SB, PA and age accounted for 27.1% of the variance in BMI. Time spent in SB should be considered when designing obesity interventions for adults 50 years and older. |
