Physical Activity And Sedentary Time In U.S. Adults With And Without Heart Failure: 2007-2018 NHANES

Current evidence describing physical activity (PA) and sedentary time (ST) in people with and without heart failure (HF) is limited. PURPOSE: This study examines PA participation and ST in a nationally representative sample of U.S. adults with and without self-reported HF. METHODS: Study sample (N = 21,646) included U.S. adult (≥ 40 years of age) participants from the 2007-2018 National Health and Nutrition Examination Survey. PA participation (meeting or not meeting PA recommendations), ST (≤4.5 hours/day or > 4.5 hours/day), and HF status (yes/no) were assessed via questionnaire. RESULTS: Compared to participants without HF (68%), 84% of participants with HF reported not meeting PA recommendations (P < 0.01). Compared to participants without HF (63%), 75% of participants with HF reported >4.5 hours/day of ST (P < 0.01). Unadjusted analysis suggests that participants with HF had 60% (P < 0.05) lower odds of reporting meeting PA recommendations when compared to a referent group without HF. In a fully adjusted model, these odds were attenuated (Odds Ratio 0.64 [P < 0.05]). Similar unadjusted analysis illustrated those individuals with HF had 42% (P < 0.05) lower odds of reporting ≤4.5 hours/day of ST. In a fully adjusted model, these odds were also attenuated (Odds Ratio 0.67 [P < 0.05]). CONCLUSIONS: Our findings suggest that U.S. adults with HF report significantly less PA and greater amounts of ST than those without HF.
