Even in later years, adopting and maintaining healthy habits can contribute to a longer life, according to a study published online on June 20, 2024, in JAMA Network Open. The research focused on 5,222 individuals aged 80 and older, examining their lifestyles to determine who among them lived to 100 years or more (centenarians) and who did not.
Participants' lifestyles were assessed on a scale from zero to six, with higher scores indicating healthier behaviors. The scoring was based on factors such as diet diversity, regular physical activity, smoking status, alcohol consumption, and body mass index (BMI). Those who scored between five and six were found to have the longest life spans and the highest likelihood of reaching 100 years. Conversely, those with scores between zero and two had the shortest life spans.
The study highlighted three key lifestyle habits that had the most significant impact on longevity: a balanced diet, regular exercise, and not smoking. Centenarians in the study typically consumed high amounts of fruits, vegetables, fish, beans, and tea. They also engaged in regular physical activities like running and qi gong and refrained from smoking. Interestingly, alcohol consumption and BMI did not seem to influence whether a participant reached 100.
