Hypothermia-related deaths--United States, 2003.
Hypothermia, a preventable lowering of the core body temperature to <95 degrees F (<35 degrees C), causes approximately 600 deaths each year in the United States. Exposure to excessive cold (or excessive exposure to cold) slows enzymatic activity throughout the body, leading to potentially fatal rhabdomyolysis, coagulopathy, renal failure, and dysrhythmias. Alcohol intake, activity level, and type of clothing are among the modifiable factors associated with hypothermia. Understanding the epidemiology and pathophysiology of hypothermia is important to preventing hypothermia-related mortality. This report describes three cases of fatal hypothermia that occurred during 2003, reviews national statistics on mortality from cold exposure in 2001, and provides recommendations for the diagnosis, treatment, and prevention of hypothermia. Public health strategies tailored to U.S. populations at increased risk for exposure to excessive cold can help reduce mortality and morbidity from hypothermia.
