Socio environmental determinants of cardiovascular mortality and hospitalization risk in arid and semi-arid regions – a case study for Gonabad city,Iran 2017-2022

Abstract Background Since questioning regarding climate and incidents of cardiovascular rates have been debated. This study was designed to investigate the association between cardiovascular mortality hospitalization risk and demographic-meteorological factors in the arid and semi-arid zone of Iran during (1st April 2017 and 31st December 2022). Methods Logistic and negative binomial regression and Pearson regression were used for analysis. Results A mean age of 61.52 years old (49.5% female and 50.5% male) was recorded for the hospitalization. Peak numbers of daily hospitalization were observed in winter (18%), followed by autumn (16%). Cardiovascular hospitalization presented a significant positive correlation with the wind (P = 0.05) and temperature (P = 0.016) in the hot season, whereas showing a negative correlation with humidity (P = 0.013) and wind factor (P = 0.05) in the cold season. Similarly, a negative correlation between cardiovascular mortality and speed of wind (P = 0.05) was observed in summer. Conclusion It concluded that there were associations between demographic-meteorological factors and the occurrence of cardiovascular hospitalization-mortality in arid and semiarid region.
