Hypothesis
To identify factors which determine high life satisfaction and to analyze the prognostic influence of life satisfaction on mortality.
Conclusion
Higher life satisfaction is associated with a significant long-term survival benefit in men, but not in women.
Supporting Evidence
- Participants with higher life satisfaction had lower mortality rates.
- The study found that psychological and social factors were significant determinants of life satisfaction.
- Men with higher life satisfaction had a 39% survival benefit compared to those with lower satisfaction.
Takeaway
Being happy with your life can help you live longer, especially for men.
Methodology
Data were collected from 2,675 participants aged 25-74 years, using multivariate logistic regression analyses and Cox proportional hazards models over a mean follow-up of 12 years.
Potential Biases
Potential bias due to the exclusion of participants with missing values and the reliance on self-reported measures.
Limitations
The study's response rate was 55%, which may limit the generalizability of the findings.
Participant Demographics
Participants were aged 25-74 years, with 53% male and a mean age of 47 years.
