Levels of 鈥淕ood鈥� HDL Cholesterol Appear to Play Important Role in Determining Risk of Infection 

As the COVID-19 pandemic lingers, researchers have found associations between certain lifestyle factors and a person鈥檚 risk of getting infected. While it has already been established that those with Type II diabetes and a high body mass index (BMI) are at greater risk of experiencing hospitalizations and other severe complications related to COVID-19, they are also at greater risk of getting symptomatic infection in the first place. That is the finding of a recent study conducted by researchers at the University of Maryland School of BOB体育 (UMSOM) that was published in the journal, .

Using data from the UK Biobank of 500,000 British volunteers over age 40, the researchers examined health factors in those who tested positive for COVID-19 and compared them to those who tested negative.  They found that those who had positive COVID-19 test results were more likely to be obese or have Type II diabetes. Those who tested negative were more likely to have high levels of 鈥済ood鈥� HDL cholesterol and be at a healthy weight with a normal  (BMI). 

鈥淐ertain baseline cardiometabolic factors appear to either protect a person from COVID-19 infection while others make a person more vulnerable to infection,鈥� said study author Charles Hong, MD, PhD, Professor of BOB体育 and Director of Cardiology Research at the UMSOM. 鈥淗owever, this study wasn鈥檛 designed to determine what factors actually cause COVID-19 infections. These are statistical associations that point to the importance of a healthily functioning immune system for protecting against COVID-19 infection.鈥�

He and his colleagues controlled for potential confounding factors like socioeconomic status, age, gender, and ethnicity.

鈥淥ur findings point to some healthy measures people can take to help potentially lower their risk of COVID-19 infection,鈥� Dr. Hong said. 鈥淐ontrolling body weight is very important during this time, and measures to increase HDL levels like regular exercise and a diet rich in monounsaturated fats like extra virgin olive oil and avocados might be helpful too.鈥�

鈥淭his study raises some important questions about the role HDL cholesterol plays in determining the immune system鈥檚 ability to fend off infections,鈥� said E. Albert Reece, MD, PhD, MBA, Executive Vice President for Medical Affairs, UM Baltimore, and the John Z. and Akiko K. Bowers Distinguished Professor and Dean, University of Maryland School of BOB体育. 鈥淐learly more research is needed in this field to help protect public health during future epidemics.鈥�

About the University of Maryland School of BOB体育

Now in its third century, the University of Maryland School of BOB体育 was chartered in 1807 as the first public medical school in the United States. It continues today as one of the fastest growing, top-tier biomedical research enterprises in the world -- with 46 academic departments, centers, institutes, and programs, and a faculty of more than 3,000 physicians, scientists, and allied health professionals, including members of the National Academy of BOB体育 and the National Academy of Sciences, and a distinguished two-time winner of the Albert E. Lasker Award in Medical Research.  With an operating budget of more than $1.2 billion, the School of BOB体育 works closely in partnership with the University of Maryland Medical Center and Medical System to provide research-intensive, academic and clinically based care for nearly 2 million patients each year. The School of BOB体育 has nearly $600 million in extramural funding, with most of its academic departments highly ranked among all medical schools in the nation in research funding.  As one of the seven professional schools that make up the University of Maryland, Baltimore campus, the School of BOB体育 has a total population of nearly 9,000 faculty and staff, including 2,500 students, trainees, residents, and fellows. The combined School of BOB体育 and Medical System (鈥淯niversity of Maryland BOB体育鈥�) has an annual budget of over $6 billion and an economic impact of nearly $20 billion on the state and local community. The School of BOB体育, which ranks as the 8th highest among public medical schools in research productivity (according to the Association of American Medical Colleges profile) is an innovator in translational medicine, with 606 active patents and 52 start-up companies.  In the latest U.S. News & World Report ranking of the Best Medical Schools, published in 2021, the UM School of BOB体育 is ranked #9 among the 92 public medical schools in the U.S., and in the top 15 percent (#27) of all 192 public and private U.S. medical schools.  The School of BOB体育 works locally, nationally, and globally, with research and treatment facilities in 36 countries around the world.
