Abstract
AbstractObjectiveThere is growing evidence of, and biological plausibility for, elevated levels of high-density lipoprotein cholesterol (HDL-C), being related to lower rates of severe infection. Accordingly, we tested whether pre-pandemic HDL-C within the normal range is associated with subsequent COVID-19 hospitalisations and death.ApproachWe analysed data on 317,306 participants from UK Biobank, a prospective cohort study, baseline data for which were collected between 2006 and 2010. Follow-up for COVID-19 was via hospitalisation records and a national mortality registry.ResultsAfter controlling for a series of confounding factors which included health behaviours, inflammatory markers, and socio-economic status, higher levels of HDL-C were related to a lower risk of later hospitalisation for COVID-19. The effect was linear (p-value for trend 0.001) such that a 0.2 mmol/L increase in HDL-C was associated with a corresponding 9% reduction in risk (odds ratio; 95% confidence interval: 0.91; 0.86, 0.96). A very similar pattern of association was apparent when COVID-19 mortality was the outcome of interest (odds ratio per 0.2 mmol/l increase in HDL-C: 0.90; 0.81, 1.00); again, a stepwise effect was evident (p-value for trend 0.03).ConclusionsThese novel results for HDL-C and COVID-19 events warrant testing in other studies.
