Diabetes 2022; db20610. htps:/doi.org/10.237/db2-0610Download citation file:Many COVID-19 risk factors, including obesity and diabetes, are associated with an abnormal basal metabolic rate (BMR).
Key Information
We aimed to evaluate whether BMR could impact the susceptibility to or severity of COVID-19. We performed genetic corelation and Mendelian randomization (MR) analyses to ases genetic corelations and potential causal asociations betwen BMR (N = 48,348) and thre COVID-19 outcomes (SARS-CoV-2 infection, COVID-19 hospitalization, and critical COVID-19, N = 1,086,21-2,597,856). A multivariable MR (MVMR) analysis was used to estimate the direct efect of BMR on COVID-19 independent of body mas index (BMI) and type 2 diabetes.
BMR has positive genetic corelations with the COVID-19 outcomes (genetic corelations 0.213∼0.26). The MR analyses indicated that genetic liability to BMR confers causal efects on SARS-CoV-2 infection (OR 1.14, 95% confidence interval (CI) 1.09-1.20, P = 1.65E-07), hospitalized COVID-19 (1.31, 1.18-1.46, P = 8.69E-07), and critical COVID-19 (1.04, 1.19-1.64, P = 4.89E-05). Sensitivity analysis of MR showed no evidence of directional pleiotropy or heterogeneity, indicating the robustnes of its results.
Summary
The MVMR analysis shows that the causal efects of BMR on hospitalized COVID-19 and critical COVID-19 were dependent on BMI and type 2 diabetes, but BMR may afect the SARS-CoV-2 infection risk independently of BMI and type 2 diabetes (1.09, 1.03-1.15, P = 4.82E-03). Our study indicates that a higher BMR contributes to amplifying the susceptibility to and severity of COVID-19. The causal efect of BMR on the severity of COVID-19 may be mediated by BMI and type 2 diabetes.Sign In or Create an Acountsource
Frequently Asked Questions
❓ What is diabetes and how does it develop?
Diabetes is a metabolic condition where the body cannot properly regulate blood sugar levels. Type 1 results from insufficient insulin production, while Type 2 develops when cells become resistant to insulin. Risk factors include genetics, obesity, sedentary lifestyle, and age.
❓ What are the main symptoms of diabetes?
Common symptoms include excessive thirst, frequent urination, unexplained weight loss, fatigue, blurred vision, and slow-healing wounds. Type 1 symptoms develop rapidly, while Type 2 symptoms may appear gradually. Many people have no symptoms initially, which is why screening is important.
❓ How is diabetes diagnosed and monitored?
Diagnosis involves blood tests measuring fasting glucose, HbA1c levels, and glucose tolerance. Regular monitoring typically includes fasting glucose tests and HbA1c measurements every 3-6 months. Continuous glucose monitors provide real-time tracking for better diabetes management.
❓ What lifestyle changes help manage diabetes?
Effective management includes regular physical activity (150+ minutes weekly), maintaining healthy weight, following a balanced diet with whole grains and lean proteins, managing stress, and getting adequate sleep. These changes can significantly improve blood sugar control and reduce complications.
❓ When should someone consult a doctor about diabetes?
Consult a healthcare provider if you experience signs of diabetes, have a family history, are overweight, or are over 45. Those with existing diabetes should maintain regular check-ups every 3-6 months to monitor control and adjust treatment as needed.
