Obesity-related factors are believed to be associated with an increased risk of contracting various viral diseases. Some 26,030 were tested as part of the study between March 16 and December 31 2020, among whom 1,178 positive Covid-19 results were recorded. Researchers found the relationship between BMI and the probability of a patient testing positive remained significant even after age, sex and other medical conditions were considered. The study also found that people with diabetes were 30% more likely to test positive, while the likelihood was six times greater in those with high blood pressure. However, the risk was reduced in people with a history of a stroke, ischemic heart disease and chronic kidney disease by 39%, 55% and 45%, respectively.
