Objective: Spontaneous aneurysmatic subarachnoid hemorrhage (SAH) attributes to early mortality and carries a high risk of long-term disability. A correlation between temperature variation and SAH incidence has been reported. However, the relation to Global Horizontal Irradiation has not been analyzed yet. Global Horizontal Irradiation presents the amount of radiation directed to horizontal surfaces of the Earth. The objective of this study is to examine whether SAH incidence correlates to Global Horizontal Irradiation as well as to known meteorological parameters such as outside temperature and sun exposure.

Methods: SAH incidences from 29 countries were extracted from 75 studies based on a recent meta-analysis of our working group. Data for Global Horizontal Irradiation was obtained from the Global Solar Atlas, a solar resource database provided by the World Bank Group. Sun exposure and temperature values were obtained from the Open Source Data of the German Meteorological Service. Statistical analysis of the data was performed with R Studio (R Version 4.1.2; Boston, USA).

Results: Mean crude SAH incidence per 100.000 person-years in 29 countries was 7.93 + 4.25 SD with an average of 1587.14 kWh/m2+ 440.7 SD of Global Horizontal Irradiation. Annual sun exposure and temperature were 190.03 hours per month + 20.68 SD and 16.45°C + 4.21 SD. The correlation analysis showed a significant negative correlation between crude SAH incidence and Global Horizontal Irradiation (p=0.02) as well as average global temperatures (p=0.02). Sun exposure did not correlate significantly with SAH incidence (p=0.07).

Conclusion: In this study, the SAH incidence correlated significantly with Global Horizontal Irradiation in accordance with seasonal parameters such as outside temperatures. However, SAH incidences are underreported especially in emerging and developing countries. Future neurovascular research should include data collection on a more global level and might benefit from further data analysis of meteorological parameters including solar power and temperature changes with regards to ongoing climate change.
