  1.

  2. Objectives • 1. To determine associations of total sitting time with HRQoL • among a sample of older men. • 2. To describe the domain-specific sitting behaviors among • older men. • Older men have the highest levels of sedentary time in the US. • PA and HRQoL • Sedentary time and HRQoL

  3. Methods • Men > 55 years of age recruited by advertisement. • Total and domain specific sitting: • 1) travelling places • 2) at work • 3) watching TV • 4) using a computer at home • 5) at leisure (Marshall et al., 2010. • Weekday and weekend • HRQoL: RAND-12

  4. Results • N = 375 (375/484 = 84% response rate) • Mean age = 65 years • BMI = 26.9 • Based on HRQoL, majority had some form of disability • PHC = 52.9 MCH = 51.1 GHC = 51.9 • Weekday sitting time: 9.3 hours (SD = 7) • Weekend sitting time: 8.3 hours (SD = 5.2)

  5. Adjusted differences in HRQoL across weekday sitting time quartiles

  6. Adjusted differences in HRQoL across weekend sitting time quartiles Q1 vs. Q4 Mdiff = 2.3 p = .05 Mdiff = 2.9, p < .05 * *

  7. Conclusions • Only 2 other studies examined sedentary time and HRQoL. • Appears to be measurement issues as initial validation work suggests. • Recall bias. • Study is the first to examine sitting across multiple domains and HRQoL among any population. • Sedentary behavior self-report tools need • to be refined and improved.

  8. Thank you!
