Impact of Meteorological Parameters on Suicide Rates in Germany (ongoing)

Study objective:
This study aims to investigate the impact of daily meteorological conditions (e.g. air temperature or sunshine duration) on the risk of committing suicide based on mortality and meteorological data gathered in four Bavarian cities and eleven counties between 1990 and 2006.

Specific aims:

  • Evaluation of air temperature effects on suicides taking immediate, lagged, and cumulative effects into account
  • Evaluation of effects of other meteorological variables such as relative humidity, barometric pressure, sunshine duration, cloud cover, and precipitation on suicides
  • Identification of potential harmful weather conditions by performing interaction analyses between meteorological variables (e.g. air temperature and relative humidity)
  • Identification of potential effect modifiers such as age, sex, regional characteristics (e.g. cities vs. counties) or time periods with changes in medication

Study design:

Population-based time-series mortality study.

Study population:
Residents of four Bavarian cities (München, Nürnberg, Augsburg, and Rosenheim) as well as of eleven Bavarian counties (München, Fürstenfeldbruck, Garmisch-Partenkirchen, Weilheim-Schongau, Bad Tölz-Wolfratshausen, Miesbach, Rosenheim, Berchtesgadener Land, Traunstein, Augsburg, and Aichach-Friedberg).

Study period:

1990 – 2006.

Current status:
