Summary
- A study found a connection between sex, marital status, education, and race with an 18-year lifespan gap in the US.
- No single factor is more influential than the others, but having multiple influential factors increases the risk of early death.
- A scoring system based on these characteristics can help identify groups most at risk of premature death.
- Social determinants play a significant role in health and mortality, alongside individual risks and genetic factors.
- Different combinations of these social determinants impact lifespan inequalities and various causes of death differently among different groups.
A study published in the BMJ Open found that a combination of sex, marital status, education, and race can impact lifespan in the US, with an 18-year gap between certain groups. While no single factor is more influential than the others, having more of these factors increases the risk of early death. Researchers developed a scoring system to identify groups at high risk, considering 54 different combinations of these social determinants.
The study revealed wide disparities in partial life expectancies among the 54 groups, with factors such as education, marital status, race, and sex all playing a role. The scoring system developed by the researchers assigns scores based on these social determinants to identify those at high risk of early death. Marriage and higher education were found to lower the risk, but influences of race varied for different causes of death.
Overall, the researchers concluded that there is a complex interaction between social and individual determinants of health influencing lifespan and mortality. While having one high-risk characteristic may not be sufficient to predict early death, the risk increases with the number of such characteristics present. The study suggests that including additional factors in the scoring system could further enhance its precision in identifying high-risk groups.
