Suicide among post-Arabellion refugees in Germany

Area of Science:

• Public Health
• Sociology
• Epidemiology

Background:

• Immigrants are often considered vulnerable to mental illness.
• Limited research exists on suicide mortality among immigrant populations.
• Understanding suicide risk in immigrants is crucial for targeted public health interventions.

Purpose of the Study:

• To investigate standardized mortality ratios (SMR) for suicide among major immigrant groups in Germany.
• To compare suicide risk before and after the 2015 refugee influx.
• To analyze SMR for Syrian, Afghan, and Iraqi populations separately.

Main Methods:

• Utilized data from the Federal Statistical Office (2000-2020) for immigrants and the general German population.
• Calculated SMR with 95% confidence intervals using indirect standardization.
• Analyzed data for pre-2015 and post-2015 periods, overall and for specific nationalities.

Main Results:

• Immigrants exhibited a significantly lower suicide risk (SMR = 0.38) compared to the German reference population.
• No significant differences in SMR were found between the pre- and post-2015 periods for aggregate or specific immigrant groups.
• Post-2015, Afghan immigrants had a higher SMR (0.68) than Syrian (0.30) or Iraqi (0.37) immigrants.

Conclusions:

• Immigrant suicide risk in Germany remained consistently lower than the general population, irrespective of the 2015 refugee movement.
• Factors such as lower suicide rates in countries of origin and selection processes favoring resilient individuals may contribute to lower observed risk.
• Findings highlight the need for nuanced understanding of immigrant mental health and suicide prevention strategies.
