Now our recent study,has unveiled some common biomarkers, including levels of cholesterol and glucose, in people who live past 90.
Our research included data from 44,000 Swedes who underwent health assessments at ages 64-99 - they were a sample ofThese participants were then followed through Swedish register data for up to 35 years. Of these people, 1,224, or 2.7%, lived to be 100 years old. The vast majority of the centenarians were female.
We also looked at creatinine, which is linked to kidney function, and iron and total iron-binding capacity , which is linked to anaemia. Finally, we also investigated albumin, a biomarker associated with nutrition.We found that, on the whole, those who made it to their hundredth birthday tended to have lower levels of glucose, creatinine and uric acid from their sixties onwards.
When exploring which biomarkers were linked to the likelihood of reaching 100, we found that all but two of the 12 biomarkers showed a connection to the likelihood of turning 100. This was even after accounting for age, sex and disease burden. For uric acid, for instance, the absolute difference was 2.5 percentage points. This means that people in the group with the lowest uric acid had a 4% chance of turning 100 while in the group with the highest uric acid levels only 1.5% made it to age 100.
