VA Office of Research and Development
The research in this VA Merit will examine the effects of obesity and Post-COVID Conditions (PCC) on physical functioning, health-related quality of life, and adipose tissue inflammatory and cellular senescence profiles in older Veterans. Further, it will evaluate whether a weight loss intervention, including dietary modification and exercise, in obese Veterans with and without PCC will reduce systemic and adipose tissue inflammation and senescence and promote PCC recovery.
Findings of post-acute sequelae of Post-COVID Conditions (PCC) manifestations of fatigue, pain, dyspnea, and muscle weakness, provide a strong rationale for rehabilitation; yet few formal studies exist and the effects of severe acute respiratory syndrome coronavirus-2 infection on function are not well described. Notably, two-thirds of Veterans are overweight and obese, rendering excess adiposity a significant risk factor and a high-priority area related to PCC prevention and care. Obesity increases the risk of severe illness in Veterans recovering from PCC, but how it does so is not fully und…
