BACKGROUND: Sedentary time is an independent risk factor for @entity66 and mortality. It is unknown how much time individuals with @entity453 spend being sedentary or how their sedentary time relates to markers of health. The objectives of this study were to: (a) quantify sedentary time in a post-cardiac rehabilitation (CR) population, and (b) assess association with cardiometabolic risk, independent of moderate-to-vigorous physical activity. DESIGN: Cross-sectional. METHODS: As part of a larger trial, 263 recent CR graduates (   10 days post-CR, mean age 63.6        9.3 years, 75% male) wore an ActiGraph GT3X accelerometer during waking hours (>= 4 days, >= 10 hours/day) to quantify sedentary time ( <=150 counts per minute). Spearman correlations were computed to assess relationships between sedentary time (adjusted for wear time) with markers of @entity283 and @entity410 . Significant markers were examined using multiple linear regressions. RESULTS: @entity1 spent an average of almost 8 hours/day sedentary (   14 bouts/day). Sedentary time was negatively correlated with high-density lipoprotein and [Formula: see text]O2peak and positively correlated with @entity1674 , body mass index and waist circumference. After adjusting for age, sex, medications and moderate-to-vigorous physical activity, hours/day of sedentary time remained significantly associated with log[Formula: see text]O2peak (b   =   -0.02, p   =   0.003) and body mass index (b   =   0.47, p   =   0.03). CONCLUSIONS: Findings suggest that even among a group of post-CR individuals who are already probably more active than @entity1 who have not undergone CR, sedentary time remains high and is associated with poorer @entity410 , suggesting a possible new area of focus among CR programs.
