Abstract P495: Trends in Physical Activity Among US Older Adults With Heart Failure 2007-2016

Introduction: Heart failure (HF) is a growing public health problem which is the leading cause of hospitalization. About half of people who develop HF die within 5 years of diagnosis. Recent evidence suggests that physical inactivity may be an important risk for HF. However, the importance of physical activity in the prevention and treatment have not been adequately recognized. Self-reported physical activity can provide insights into the impact of lifestyle behaviors on mortality. The objective of this study was to determine the relationship between physical activity and HF in a nationally representative sample of United States (US) adults. Methods: The 2007-2016 National Health and Nutrition Examination Survey data collection cycles were used for this analysis. Participants aged 65 and older with HF were defined as those who answered “yes” to the question: “Has a doctor or other health professional ever told you that you had congestive HF?” Frequency and duration of self-reported moderate-intensity (“Days moderate recreational activities” and “Minutes moderate recreational activities”) and vigorous-intensity Days vigorous recreational activities” and “Minutes vigorous recreational activities”) physical activity were collected through questionnaires as well in all data cycles. We used 2018 Physical Activity Guidelines for Americans Older Adults, which recommended that most older adults (age≥65 years) participate in at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity aerobic activity per week as our cut-off points for calculating moderate-to-vigorous physical activity. Results: Between 2007-2008 and 2015-2016, the percentage of US adults ≥65 years with HF increased from 2.76% to 3.69% (p=0.04). Although a similar percentage of participants who met the criteria of at least 150 minutes of moderate-intensity activity per week was noted in both groups from 2007 to 2016 (on average, HF: 56.9% vs. HF-free: 56.7%, respectively, p>0.05), more HF-free participants reported at least 75 minutes of vigorous-intensity recreational activities per week compared to HF participants in each calendar year (82.8% vs. 66.7%, 85.0% vs. 70.0%, 83.5% vs. 55.0%, 87.0% vs.75%, 85.2% vs. 63.6%, respectively, p<0.01). Additionally, among those who reported activities, older adults with HF were less than 20 times as likely to report moderate or vigorous recreational activities compared to those without HF. Conclusions: Our findings illustrate lower self-reported physical recreational activities, especially vigorous activities, in older participants who report a diagnosis of HF and more participants without HF report vigorous-intensity recreational activities. Future study should focus on understanding the physical limitations of HF patients, which is paramount in developing cardiac rehabilitation strategies to improve their function capacity.
