Sedentary Behaviors Increase Risk of Cardiovascular Disease Mortality in Men

Abstract

Purpose-To examine the relationship between two sedentary behaviors (riding in car and watching television) and cardiovascular disease (CVD) mortality in men in the Aerobics Center Longitudinal Study.Methods-Participants were 7,744 men (20-89 yr) initially free of CVD who returned a mailback survey during 1982. Time spent watching TV and riding in a car were reported. Mortality data were ascertained through the National Death Index till Dec 31, 2003. Cox regression analysis quantified the association between sedentary behaviors (hr/wk watching television, hr/wk riding in car, total hr/wk in these two behaviors) and CVD mortality rates.Results-377 CVD deaths occurred during 21 years of follow-up. After age-adjustment, time riding in a car and combined time spent in these two sedentary behaviors were positively (p trend <.001) associated with CVD death. Men who reported >10 hrs/wk riding in a car or >23 hr/wk of combined sedentary behavior had 82% and 64% greater risk of dying from CVD than those who reported <4 hr/wk or <11 hr/wk, respectively. The pattern of the association did not materially change after multivariate adjustment. Regardless of the amount of sedentary activity reported by these men, being older, normal weight, normotensive, and physically active was associated with a reduced risk of CVD death.Conclusion-In men, riding in a car and combined time spent in these two sedentary behaviors were significant CVD mortality predictors. Additionally, high levels of physical activity were related to notably lower rates of CVD death even in the presence of high levels of sedentary behavior. Health promotion efforts targeting physically inactive men should emphasize both reducing sedentary activity and increasing regular physical activity for optimal cardiovascular health.

Physical Activity and Risk of Fatal or Non-Fatal Cardiovascular Disease Among CVD Survivors

“…Previous studies reported the estimation of physical activity in females is difficult because domestic activity tends to be misclassified. 27 This may have occurred in our study for females. We may not have completely eliminated CVD survivors with severe after-effects, which could lead to a reverse causal relationship in our analysis.…”

“…According to past studies, pro-inflammatory cytokines were found to be elevated in highly stressed individuals [15][16][17][18][19]. Physical inactivity and sedentary lifestyle were also found to be associated with increased risk of developing chronic low grade inflammatory states [20][21].…”
