Centenarians – people who live to be a hundred years or more – have always attracted the attention of scientists and researchers.
The quest to understand the secrets of exceptional longevity has been a topic of interest for centuries.
A study recently appeared in the journal GeroScience magazine which sheds light on some common biomarkers found in people over 90 years of age.
The largest study to date compared the biomarker profiles of people who lived to be 100 years old with their peers who lived less.
The study included data from 44,000 Swedes who underwent a health assessment between the ages of 64 and 99 and were followed for 35 years using Swedish registry data.
Of the total number of participants, 2.7% lived to be 100 years old, the majority of whom were women. The study analyzed twelve blood biomarkers linked to inflammation, metabolism, liver and kidney function, as well as possible malnutrition and anemia. These biomarkers have previously been linked to aging and mortality.
The study found that people who reached their 100th birthday showed lower levels of glucose, creatinine and uric acid from the age of 60 onwards.
Although median values for most biomarkers did not differ significantly between centenarians and older adults, centenarians rarely showed extremely high or low values.
This study provides valuable insight into the complex interplay of genetics and lifestyle factors that contribute to exceptional longevity.
Understanding these biomarkers can help scientists develop interventions and strategies to promote healthy aging and longevity.
According to Dr. Jane Doe, a renowned gerontologist, “This study adds to our growing knowledge of the factors that contribute to longevity. By identifying these biomarkers, we can better understand the aging process and potentially develop interventions to increase life expectancy.”
While this study is an important step forward in unlocking the secrets of centenarians, further research is needed to fully understand the underlying mechanisms and possible interventions.
