Mortality Statistics

Background:

Suicide prevention is a public health priority.
Accurate suicide mortality data is crucial for evaluating interventions.
Existing data quality and international comparability are significant concerns.

Purpose of the Study:

Identify biases in suicide mortality data.
Assess data comparability across countries.
Determine the impact of biases on conclusions.

Main Methods:

Analyzed death certificate systems and international literature on data quality.
Assessed "concurrent" death causes (undetermined intent, unknown causes).
Extrapolated and corrected official data using survey estimates.

Main Results:

Practices in death certification vary significantly internationally, affecting data.
Official suicide rates are underestimated due to under-reporting.
Sociodemographic and geographic factors of suicide remain consistent post-correction.

Conclusions:

Despite under-reporting, French suicide data accurately reflects key trends.
International comparisons of suicide rates require careful consideration of biases.
Recommendations are proposed to improve data quality and physician reporting.
