Pollutants and climatic conditions related to the smoking rate

Smoking is considered a coping behavior for stress. On the other hand, pollutants and climatic conditions are environmental stressors that can have a negative impact on health. Therefore, there may be a link between regional smoking rate and air pollution and climatic conditions.
To clarify the relationship between the regional smoking rate in Japan and the environmental conditions such as photochemical oxidants concentration, ambient temperature and relative humidity, multiple regression analysis was performed.
Correlation analysis showed that the ambient temperature and relative humidity and photochemical oxidants are negatively correlated with smoking rate. Stepwise multiple regression analysis with smoking rate as the objective variable, the ambient temperature and relative humidity and photochemical oxidants as explanatory variables, revealed that the ambient temperature and relative humidity and photochemical oxidants are significant independent variables.
The above results suggest that ambient temperature, relative humidity and photochemical oxidants in the region may be related to smoking rate in the region.
