Brazilian Suicide Mortality Trends by Region, Sex, and Age, 1996-2015

A 20-year ecological time series from 1996 to 2015 analyzes suicide mortality trends across Brazilian regions using data from the Mortality Information System. The study by Aurean D’Eça Júnior found a growing trend in the North, Northeast, and Southeast regions and a decreasing trend in the South, with a significant prevalence of male deaths. It employs Prais-Winsten regression and chi-square tests to evaluate trends and associations with sex and age.

Use Cases

• Analyzing regional suicide mortality trends based on the 1996-2015 time series data.
• Investigating associations between suicide rates and demographic factors like sex and age.
• Modeling public health interventions using the identified regional growth and decline patterns.

Strengths

• 20 years of longitudinal data from 1996 to 2015 provides a substantial time series for trend analysis.
• Analysis covers multiple Brazilian regions, allowing for geographic comparison.
• Statistical methods like Prais-Winsten regression and chi-square tests are specified for evaluating trends and associations.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
