Introduction:
Mental health is one of the most important and influential issues in the health system. In addition to the sufferings and limitations it creates, suffering from mental illness imposes a heavy economic burden and costs on the patient's family and the society. The purpose of this study was to determine the geographic distribution of mental disorders and some related environmental factors in Boyer Ahmad and Dana counties, using GIS software, in a 5-year period from 2018-2019.
Materials and methods:
In this cross-sectional study, first, the residential address of 3215 patients with mental disorders who had a history of hospitalization in Shahid Rajaei Yasuj Psychiatric Hospital during the last 5 years were collected from hospital files and hospital archives. The relationship between climatic and environmental factors of the province, including average annual humidity, average annual rainfall, average annual temperature, after preparing and constructing the layers, were investigated and analyzed with Arcmap and Arc catalogue software from ArcGIS. Statistical analysis of the data was done using SPSS 21 software and logistic regression method.
Findings:
Based on the multivariate logistic regression results, the most important environmental factors are temperature (p < 0.001), and altitude (P =0.006) Accordingly, by increasing temperature, and altitude the chance of disease occurrence decreases by 51 % (OR=0.49) and 1 % (OR = 0.99), respectively.. Also, univariate logistic regression shows that humidity, slope (P < 0.001) and rainfall (P = 0.01) with the odds ratios of (OR=0.61), (OR=0.92), (OR=0.99), respectively, are associated with the decrease in the occurrence of mental disorders. Living in urban areas has a direct relationship with the occurrence of disease (P = 0.03), which increases the chance of mental disorders more than 7 times (OR = 7.77).
Conclusion:
According to the findings of this study, it is suggested that the increase in temperature, altitude, humidity, slope, and rainfall are related to the decrease in the incidence of mental disorders respectively, and that urban life is related to the increase in the incidence of mental disorders in studied areas. That the health system officials and practitioners use the results of this study in determining risk areas for disease control, which will lead to a significant reduction in the costs of diagnosis and treatment of mental disorders.
