Background: The Coronavirus disease MESHD 2019 (COVID19) pandemic is straining the healthcare system, particularly for patients with severe outcomes who require admittance to the intensive care unit (ICU). This study aimed to investigate the potential associations of obesity MESHD obesity HP and diabetes with COVID19 severe outcomes, assessed as ICU admittance. Subjects: Demographic and patient characteristics from a retrospective cohort of 1158 patients hospitalized with COVID19 in a single center in Kuwait, along with their medical history, were analyzed. Univariate and multivariate analyses were performed to explore the associations between different variables and ICU admittance. Results: From the 1158 hospitalized patients, 271 (23.4%) had diabetes, 236 (20.4%) had hypertension MESHD hypertension HP and 104 (9%) required admittance into the ICU. From patients with available measurements, 157 (21.6%) had body mass index (BMI)[≥]25 kg/m2. Univariate analysis showed that overweight MESHD overweight HP (BMI=25.0~29.9 kg/m2), obesity MESHD obesity class HP class I (BMI=30~34.9 kg/m2) and morbid obesity MESHD obesity HP (BMI[≥]40 kg/m2) associated with ICU admittance (odds ratio (OR) [95% confidence intervals (CI)]: 2.45 [1.26~4.74] p value=0.008; OR [95% CI]: 3.51 [1.60~7.69] p value=0.002; and OR [95% CI]: 5.18 [1.50~17.85] p value=0.009], respectively). Patients with diabetes were more likely to be admitted to ICU (OR [95% CI]: 9.38 [5.49~16.02]). Two models for multivariate regression analysis were used, assessing either BMI or diabetes on ICU outcomes. In the BMI model, class I obesity HP obesity and morbid MESHD obesity MESHD obesity HP were associated with ICU admittance (adjusted OR (AOR) [95% CI]: 2.7 [1.17~6.20] p value=0.019 and AOR [95% CI]: 3.95 [1.00~15.20] p value=0.046, respectively). In the diabetes model, diabetes was associated with higher ICU admittance (AOR [95% CI]: 5.49 [3.13~9.65] p value<0.001) whereas hypertension MESHD hypertension HP had a protective effect on ICU admittance (AOR [95% CI]: 0.51 (0.28-0.91). Conclusions: In our cohort, overweight MESHD overweight HP, obesity MESHD obesity HP and diabetes in patients with COVID19 were associated with ICU admittance, putting these patients at higher risk of poor outcomes.
