Your personality could predict how long you will live. According to the latest study, an individual’s personality traits can help show their longevity. However, personality traits change with age and this may happen due to different factors that link to mortality risk.
Now researchers analyzed personality traits in adolescence to see whether they could help predict mortality risk. The new study was conducted by researchers’ group from the American Institute for Research in Washington DC, the University of Illinois, Champaign-Urbana, and the University of Rochester Medical Center in New York.
The team looked at the adaptive personality traits of nearly a thousand people. These individuals were high school students in 1960. The researchers then analyzed whether these traits were associated with longevity of the individuals. The findings were published in The BMJ.
The study authors looked at data of 377,016 students aged between 13 and 18 years old. The researchers used data collected by the Project Talent Study, nationwide comprehensive study of high school students.
At that time, the study analyzed 10 personality traits including calmness, impulsivity, vigor, self-confidence, social sensitivity (empathy), tidiness (orderliness), culture (or a sense of curiosity), d mature personality, and sociability.
In the current research, for the final result, the investigators assessed the data of 26,845 participants from 1,171 schools.
The team found that of these, 13.12 percent participants died throughout an average investigation period of 48 years.
Moreover, the researchers explain that individuals who had scored high in social sensitivity (empathy), sense of curiosity, calmness, the degree of maturity, and tidiness, but had scored low in impulsivity developed the low risk of all-cause death over the same period.
“In fully adjusted models one standard deviation change in personality traits was associated with 5–7 percent increases or decreases in 48-year relative risk of death,” the study authors explain.
