Swedes are defying the odds by living longer than ever before. In the past, reaching the age of 85-90 was considered rare, but now, a majority of individuals reach this milestone, with two percent even reaching the impressive age of 100. According to Karin Modig, an Associate Professor at the Institute of Environmental Medicine at Karolinska Institutet, centenarians are now the fastest-growing age group in Sweden.
In a recent study published in the journal GeroScience, Modig and her team have discovered that it is possible to predict who has the highest likelihood of living to a very old age early on in life. The study, which analyzed data from approximately 44,000 Swedes who underwent health examinations between 1985 and 1996, revealed that 1,224 individuals in the study group lived to be 100 years old.
The findings of the study suggest that reaching the age of 100 is not solely a matter of chance, but is also influenced by lifestyle choices. By examining biomarkers associated with aging and disease, the researchers found that centenarians had better health markers in their 60s compared to their peers. Out of the twelve biomarkers studied, all but two were linked to increased chances of reaching 100 years old. Low iron levels and low total cholesterol were associated with reduced odds of reaching this age, indicating potential health issues.
Four biomarkers emerged as particularly crucial indicators of longevity. Normal creatinine levels, which reflect kidney health, were prevalent in individuals who lived to 100. Similarly, liver markers and uric acid levels, a marker for inflammation, were within normal ranges in centenarians. Those with the lowest uric acid levels had a four percent chance of reaching 100, while those with the highest levels had a 1.5% chance. Maintaining blood sugar levels below 6.5 mmol/liter also played a significant role in longevity.
Modig believes that lifestyle changes can potentially increase one’s chances of living to 100. However, she emphasizes the importance of finding a balance between risk factors and health factors in life. While the study provides valuable insights into predicting who will live to 100, Modig acknowledges that life is not governed by algorithms and that individual choices and circumstances also play a significant role in longevity.
Overall, the study sheds light on the factors that contribute to living a long and healthy life and opens up possibilities for individuals to make positive changes to extend their lifespan. By understanding the biomarkers associated with longevity, individuals can take proactive steps to improve their health and increase their chances of reaching 100 years of age.
