Author Information

Primary Institution: University of Central Lancashire

Hypothesis

There will be no relationship between the prevalence of obesity and national elderly suicide rates.

Conclusion

Elderly suicide rates in females are independently associated with the prevalence of obesity.

Supporting Evidence

  • There were significant negative correlations between the prevalence of obesity in females and the suicide rates in females aged 65-74 and 75+ years.
  • The independent predictors of suicide rate in females included the national prevalence rate of obesity and divorce rates.
  • The study suggests a need for confirmation in individual-level case-control or cohort studies.

Takeaway

This study found that as obesity rates go up, the number of elderly women committing suicide goes down, but we need to be careful about saying one causes the other.

Methodology

Potential Biases
