Investigating the association of temperature changes and Non-melanoma skin cancer in Iran: An ecological study design

Background and Objective: The incidence rate of melanoma and non-melanoma skin cancer entities is dramatically increasing worldwide. Climate change and temperature changes are important risk factors in the incidence of non-melanoma skin cancer. This study aimed to determine the incidence of non-melanoma skin cancer and temperature changes in Iran as an ecological study design.Materials and Methods: We extracted Non-melanoma skin cancer incidence data from Iran from ۱۹۹۰ to ۲۰۱۹ for males and females for all age groups from http://www.healthdata.org/. We entered the data into Joinpoint Software statistical software to present APC and AAPC and its confidence intervals. We used the site http://www.fao.org/ to extract data on temperature change and examine the correlation between Non-melanoma skin cancer and temperature change; we entered the information into R software.Findings: Non-melanoma skin cancer in males had five joint points [AAPC = ۱.۷ (۱.۶-۱.۸)]. APC is the last decrease and negative (APC = -۱.۵۰), and had five joinpoints in females [AAPC = ۱.۸ (۱.۷-۱.۹)]. APC is the last decrease and negative (APC = -۱.۱۷). There was a positive correlation between temperature change and the incidence of Non-melanoma skin cancer (r = ۰.۶۳۱, P.value ≤۰.۰۰۱).Conclusion: Our findings indicated that the increase of skin cancer was associated with temperature change. Considering the high incidence of this cancer in Iran and the increasing cost of treatment, further studies to investigate the relationship between the incidence and risk factors of the disease can be effective in preventing and controlling the disease. It is necessary to be planning for the control and prevention of this disease as a priority for health policymakers. The primary prevention in the earlier stage, the impact will be greater.
