Abstract
Epidemiological studies have revealed that the elderly and those with co-morbidities are most susceptible to COVID-19. To understand the genetic link between aging and the risk of COVID-19, we conducted a multi-instrument Mendelian randomization analysis and found that the genetic variation that leads to a longer lifespan is significantly associated with a lower risk of COVID-19 infection. The odds ratio is 0.32 (95% CI: 0.18 to 0.57; P = 1.3 × 10 -4 ) per additional 10 years of life, and 0.62 (95% CI: 0.51 to 0.77; P = 7.2 × 10 -6 ) per unit higher log odds of surviving to the 90th percentile age. On the other hand, there was no association between COVID-19 susceptibility and healthspan (the lifespan free of the top seven age-related morbidities). To examine the relationship at the phenotypic level, we applied various biological aging clock models and detected an association between the biological age acceleration and future incidence and severity of COVID-19 infection for all subjects as well as for the individuals free of chronic disease. Biological age acceleration was also significantly associated with the risk of death in COVID-19 patients. Our findings suggest a causal relationship between aging and COVID-19, defined by genetic variance, the rate of aging, and the burden of chronic diseases.
