Background According to the CDC, approximately 30% of hospitalizations for COVID-19 infection between the onset of the pandemic and November 2020 were attributed to obesity. However, there is limited data on how obesity affects the overall outcome of COVID-19 in hospitalized older adults. Methods A retrospective study was conducted using the PearlDiver database (PearlDiver Technologies, Fort Wayne, IN). Using ICD-10 codes, a cohort of patients aged 65–75 and Elixhauser Comorbidity Index (ECI) >4 with a history of obesity admitted for COVID-19 was identified. This cohort was matched with a group of patients with no history of obesity, considering age, gender, and ECI. Records from both groups were reviewed for multiple outcomes over 30 days following admission. Pearson’s chi-squared was used to compare groups. The strength of association was reported using Risk Ratios (RR). A p-value < 0.05 was deemed significant. Results There were 151,429 members in each group. Obese individuals had a higher risk of 30-day all-cause readmission (RR=1.10, CI95% 1.07–1.11, p < 0.0001), ICU admission (RR=1.11, CI95% 1.08–1.15, p < 0.0001), acute thromboembolic events (RR=1.14, CI95% 1.07–1.2, p < 0.001), and deep venous thrombosis (RR=1.21, CI95% 1.12–1.32, p < 0.00001). There was no difference in length of hospitalization. Conclusion Obesity is a modifiable risk factor that negatively affects COVID-19 outcomes in the older population. Given the prevalence of obesity in our population, primary and secondary obesity prevention is more important than ever. |
