Introduction: Findings concerning the effects of moon phases and sun activity on suicide are mixed in the international literature.
Aim: Our aim was to examine the hypothesised effects according to gender and age on Hungarian data covering more than 30 years.
Methods: Time series ARIMA models and dynamic regression models were applied in our analysis.
Results: Among women aged 20-49 years, a significant increase in the risk of suicide has been observed during proton solar events. At the same time, among women aged 50-59 years a slight but significant decrease has been identified in the risk of suicide during magnetic storms and full moons.
Conclusion: Proton solar events, geomagnetic storms and moon phases caused changes in the risk of suicide in certain age groups in the case of women only.
Keywords: geomagnetic storms; moon phases; proton solar events; suicide.
