HealthDay News — According to a study published in BMJ Open Diabetes Research & Care, an increase in mean annual outdoor temperature is associated with increased age-adjusted incidence of diabetes in the United States and with increased worldwide prevalence of glucose intolerance.

Lisanne Blauw, from Leiden University Medical Center in the Netherlands, and colleagues examined the correlation between mean annual temperature and diabetes incidence during 1996 to 2009 for each US state. Results were pooled in a meta-analysis. 

They further examined the correlation between mean annual temperature and the prevalence of glucose intolerance on a global scale.

The researchers found that, on average, age-adjusted diabetes incidence increased 0.314 per 1000 per 1 degree Celsius increase in temperature.

For the same increase in temperature, the worldwide prevalence of glucose intolerance increased by 0.170%. After adjustment for obesity these correlations persisted.

“Our findings indicate that the diabetes incidence rate in the USA and prevalence of glucose intolerance worldwide increase with higher outdoor temperature,” the authors write.
