Official Journal of the American College of Sports Medicine 1421 Board #13 May 30, 2:00 PM - 3:30 PM development and Validation of sedentary Behavior record (sBr) Instrument Rose M. D. Carter, Saori Ishikawa, James L. Farnsworth, Vaughn W. Barry. Middle Tennessee State University, Murfreesboro, TN. (Sponsor: Dr. Minsoo Kang, FACSM) (No relationships reported) Prior measures of sedentary behavior have not systematically measured sedentary activities in multiple domains and over various routinely performed daily sedentary activities with a user-friendly device. The Sedentary Behavior Record (SBR) was designed to fill the gap in the literature in measuring sedentary behavior. The SBR is an adaptation of the 3-day Physical Activity Record for the purpose of quantifying sedentary behavior time (SBT) over a 24-hour day. The SBR includes 3 domains (work, non-work sitting and lying down or reclining) and a choice of 3 activities under each domain (transportation, screen time, and other) to quantify SBT by 15-minute blocks of time for 24-hours. PurPOsE: Develop and validate the SBR instrument. METhOds: A total of 46 adults, aged 37 ± 12 years old, wore an Actigraph accelerometer and recorded subjective SBT by SBR for 7 consecutive days. Outcome measurements included SBT for 24-hour day with with sleep (SBT-S) and SBT without sleep time (SBT-NS), beginning when accelerometer is reported as off the body for sleep, measured by Actigraph (activity counts per minute < 100) and by SBR. Pearson correlations and paired sample t tests were examined to establish concurrent validity evidence. The alpha level was set at .025, adjusted by the Bonferroni technique. Intraclass correlation coefficients (ICC) were also computed for reliability. rEsuLTs: SBT-NS as measured by Actigraph (M = 574.48; SD = 83.33) and SBR (M = 524.54; SD = 180.49) had a moderate-to-strong relationship (r = .59, p < .001), and SBT-S as measured by Actigraph (M = 1041.04; SD = 148.31) and SBR (M = 987.87; SD = 196.74) had a low-to-moderate relationship (r = .31, p CONCLusIONs:Overall, the results support the potential use of SBT-NS and SBT-S from the SBR instrument. Further studies are warranted to validate the SBR instrument in other populations. 1422 Board #14 May 30, 2:00 PM - 3:30 PM Validity and reliability of Two self-report Measures to assess sedentary Behavior in Older adults Keith P.

Colbert, FACSM 1 . 1 University of Wisconsin - Madison, Madison, WI. 2 National Cancer Institute, National Institutes of Health, Bethesda, MD. (No relationships reported) PurPOsE: To examine the test-retest reliability and criterion-related validity of the Yale Physical Activity Survey for Older Adults (YPAS) and Community Health Activities Model Program for Seniors (CHAMPS) survey to assess sedentary behavior (SB) in older adults. METhOds: Adults aged 65 years and older were recruited to participate in a larger study comparing the validity of various objective and self-report measures of physical activity. Participants completed the YPAS and CHAMPS before and after a 10 day period during which they wore an Actigraph accelerometer (ACC). ACCderived average daily SB time (defined as

(No relationships reported) The increasing prevalence of overweight and obesity is a worldwide problem. Regular physical activity participation is a determinant to reverse the obesity epidemic and a key element in health promotion. PurPOsE: The purpose of this study was to investigate pedometer-determined physical activity patterns in adults with mild intellectual disabilities (MID). METhOds: A sample of 120 adults with MID (Age: M = 26.6 ±8.8) in Taiwan participated in this study. Among those participants, 52.5% were males, 31.7% lived in cities, 77.5% lived with their families, 64.2% were employed; 65% had a high school diploma, and 56.7% were overweight or obese (OW/OB; BMI, M = 23.95±4.28). Step count data were gathered using Yamax DigiWalker SW-200 pedometers from each participant for 7 consecutive days. rEsuLTs: Participants walked an average of 8868 steps per day (±4830). They had significantly higher step counts (t119 = 5.195, p
