MONDAY, April 22, 2019 (HealthDay News) — Moderate-to-vigorous physical activity (MVPA) equivalent to meeting current recommendations attenuates the association of sitting with all-cause and cardiovascular disease (CVD) mortality, according to a study published online April 22 in the Journal of the American College of Cardiology<\/i>.<\/p>\n
Emmanuel Stamatakis, Ph.D., from the University of Sydney, and colleagues calculated the multivariable-adjusted hazard ratios of sitting for different sitting-MVPA combination groups and within MVPA strata.<\/p>\n
The researchers found that during an 8.9-year follow-up period, there were 8,689 deaths (1,644 CVD deaths) among 149,077 participants. For all-cause mortality only, there was a statistically significant association between sitting and MVPA. For the least active groups (<150 MVPA minutes\/week), sitting time was associated with both mortality outcomes in a nearly dose-response manner. For those reporting no MVPA, the all-cause mortality hazard ratio was 1.52 when the most to the least sedentary groups (more than eight hours versus less than four hours\/day) were compared. Among those meeting the lower (150 to 299 MVPA minutes\/week) or upper (\u2265300 MVPA minutes\/week) limits of the MVPA recommendation, the evidence was inconsistent and weak for elevated CVD and all-cause mortality risks with more sitting. Among high sitters (more than six hours\/day), replacing sitting with walking and MVPA showed stronger associations.<\/p>\n
“Reduction of sitting time is an important strategy, ancillary to increasing physical activity, for preventing cardiovascular disease and premature mortality in physically inactive populations,” the authors write.<\/p>\n
