Prevalences of Anorexia, Autism, and Schizophrenia, Are Strongly Associated With Average Annual Temperatures: Systematic Review and Linear Regression Analysis.

ABSTRACT:

Background

The impact of potential environmental influences, like temperature changes and latitudinal gradient, has not been investigated in depth in psychiatric diseases. The aim of this project was to investigate the association of geographical latitude and temperature with the prevalence of psychiatric disorders.

Methods

Linear regression analysis was performed for 201 countries by analyzing average annual temperatures and age-standardized rates (prevalence) of seven major psychiatric entities. A systematic review was also performed, investigating if these correlation data were supported by published original studies.

Results

Linear regression analysis showed a significant correlation between average annual temperatures and age-standardized rates (p < 0.0001) for t
