Associations between heart failure and physical function in US adults

Abstract

Background: There is a paucity of nationally representative data in the area of heart failure (HF) and physical function (PF). Aim: Examine the relationship(s) between HF and PF in a nationally representative sample of United States (US) adults. Design: Cross-section analysis of US adults. Methods: Sample (n=6623) included adult (≥40 years of age) participants from the 1999-2006 National Health and Nutrition Examination Survey. Participants reporting HF answered questions related to their abilities to accomplish specific upper extremity and lower extremity tasks, and household chores. Results: Prevalence estimates of reporting much difficulty or the inability to stand from an armless chair was 9.9% and 4.3% (P=0.002) in those with and without HF, respectively. Similar estimates were revealed for much difficulty or inability to lift or carry 10 pounds (16.8% and 8.6%, P=0.0004) and much difficulty or inability to do household chores (13.3% and 6.1%, P=0.0008). Following adjustments participants reporting HF had significantly greater odds of reporting much difficulty or the inability to stand from an armless chair [odds ratio (OR) 1.93; 95% confidence intervals (CI) 1.25, 2.96], much difficulty or the inability to lift or carry 10 lbs (OR 1.90; 95% CI 1.36, 2.65) and much difficulty or inability to do household chores (OR 2.06; 95% CI 1.41, 3.02) compared with participants not reporting HF. Conclusions: Findings suggest US adults reporting HF are more likely to report poorer PF.
