Correlates of General and Domain-Specific Sitting Time among Older Adults.
OBJECTIVE
We examined the correlates of sitting time in a population-based sample of older adults.


METHODS
Adults >55 years of age (N = 1296; N = 515 employed; N = 781 unemployed) self-reported measures of demographic and health-related variables, and a measure of sitting time (ie, SIT-Q).


RESULTS
Employed total sitting time (min/day) was positively associated with home Internet access (B = 71.2, 95% CI, 8.9 to 133.4, p = .025), body mass index (BMI) (kg/m(2); B = 7.0, 95% CI, 2.1 - 11.9, p = .005), and negatively associated with physical health (B = -2.3; 95% CI, -4.9 to 0.3, p = .013). Unemployed total sitting time was negatively associated with age (B per year = -3.0, 95% CI, -4.9 to -1.1, p = .002), and being male (B = -54.0, 95% CI, -86 .7 to -21.3, p = .001). Unemployed total sitting time was positively associated with Internet access (B = 54.1, 95% CI, 17.7 to 90.4, p = .004) and BMI (B = 4.1, 95% CI, .94 to 7.3, p = .011).


CONCLUSIONS
Older adults reported low levels of sitting time. Different correlates emerged for the employed and unemployed samples across sitting domains.
