Sedentary Postmenopausal Women Have Higher Heart Failure Risk
The more time older women spent sitting or lying down, the more likely their risk of hospitalization for heart failure, based on data from more than 80,000 postmenopausal women. The 2018 Physical Activity Guidelines show evidence of the impact of physical activity on reducing heart failure risk, but the association between activity, sedentary behavior (SB) and heart failure (HF) in older women in particular has not been well studied, wrote Michael J. LaMonte, PhD, MPH, of the State University of New York at Buffalo, and colleagues in a study published in Circulation: Heart Failure. "Given the high prevalence of prolonged sedentary time among U.S. adults aged 65 and older, among whom HF burden is substantial, understanding the role SB has in HF development is relevant to future HF prevention strategies," the researchers wrote.

This risk was even greater for patients falling in the third tertile for sedentary behavior. Odds ratios were 1.00 (referent), 1.15, and 1.42 for the lowest to highest tertiles for total sedentary behavior, respectively, and 1.00 (referent), 1.14, and 1.54 for sitting (P < .001 for both total sedentary behavior and sitting only).
