Moreover there is no evidence on whether leisure-time sedentary behavior LTSB is associated with HRQoL independently of LTPA. This study examined the longitudinal association between LTPA LTSB and HRQoL in older community-dwelling adults in Spain. Methods Prospective cohort study of 1 097 persons aged 62 and over. In 2003 LTPA in MET-hr week was measured with a validated questionnaire and LTSB was estimated by the number of sitting hours per week. In 2009 HRQoL was measured with the SF-36 questionnaire. Analyses were done with linear regression and adjusted for the main confounders. Results Compared with those who did no LTPA subjects in the upper quartile of LTPA had better scores on the SF-36 scales of physical functioning b 5.65 95 confidence interval CI 1.32-9.98 p linear trend 0.001 physical role b 7.38 95 CI 0.16-14.93 p linear trend 0.001 bodily pain b 6.92 95 CI 1.86-11.98 p linear trend 0.01 vitality b 5.09 95 CI 0.76-9.41 p linear trend 0.004 social functioning b 7.83 95 CI 2.89-12.75 p linear trend 0.001 emotional role b 8.59 95 CI 1.97-15.21 p linear trend 0.02 and mental health b 4.20 95 CI 0.268.13 p linear trend 0.06 .
