Low vitamin D may increase your risk of being hospitalised with COVID-19
Observational study: A study in which the subject is observed to see if there is a relationship between two or more things (eg: the consumption of diet drinks and obesity). Observational studies cannot prove that one thing causes another, only that they are linked.
People: This is a study based on research using people.
UK and Australian scientists say having low levels of vitamin D may increase the risk of hospitalisation with COVID-19, but low levels of the vitamin are only weakly linked with the risk of contracting COVID-19. The team looked at health records for 151,543 people in the UK, and found low vitamin D increased the risk of hospitalisation among white patients, but not among Black or Asian patients. In contrast, Black and Asian populations with low vitamin D levels were at a higher risk of catching COVID-19, but this did not translate to increased hospitalisation. Vitamin D and ethnicity may independently influence COVID-19 outcomes, rather than interacting to affect risks, the authors conclude.
