A study analyzes the blood level of iron, glucose, creatinine and other markers in centenarians

Longevity is increasing, with a notable increase in the number of people reaching the age of 100. A study by the Karolinska Institute in Sweden examined 12 blood markers in a sample of 44,000 individuals, including 1,224 centenarians. The results showed that those who reach the age of 100 usually have lower levels of glucose, creatinine and uric acid from the age of 60. However, the average values of these markers do not differ significantly between centenarians and those who do not reach this age. In addition, two markers, alanine aminotransferase and albumin, showed a direct connection with the probability of reaching 100 years, while higher levels of iron and cholesterol were associated with a lower probability of reaching this longevity. 84.6% of the centenarians in the study were women, who globally tend to live longer than men.
