(HealthDay News) — Moderate and severe obesity is associated with a greater risk for postacute sequelae of COVID-19, according to a study published online June 1 in Diabetes, Obesity and Metabolism.

Ali Aminian, M.D., from the Cleveland Clinic, and colleagues followed 2,839 patients who did not require intensive care unit admission and survived the acute phase of COVID-19 for eight months from 30 days following a positive viral test.

The researchers found that 43% of patients required medical diagnostic tests, 44% had hospital admission, and 1% of patients died. The risk for hospital admission was 28% higher in patients with moderate obesity and 30% higher in patients with severe obesity compared with patients with a normal body mass index. Similarly, the need for diagnostic tests was 25% higher in patients with moderate obesity and 39% higher in patients with severe obesity compared with patients with normal BMI.

“The observations of this study can possibly be explained by the underlying mechanisms at work in patients who have obesity, such as hyper-inflammation, immune dysfunction, and comorbidities,” a coauthor said in a statement.
