TUESDAY, March 21, 2017 (HealthDay News) -- 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, according to research published online March 20 in BMJ Open Diabetes Research & Care.
Lisanne L. 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 U.S. 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 1,000 per 1 degree Celsius increase in temperature. For the same increase in temperature, the worldwide prevalence of glucose intolerance increased by 0.170 percent. 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.
