Update: Exertional rhabdomyolysis, active component, U.S. Armed Forces, 2011

Area of Science:

• Military Medicine
• Environmental Health
• Sports Medicine

Background:

• Exertional rhabdomyolysis (ER) is a serious condition linked to strenuous physical activity and heat stress.
• Understanding ER incidence and risk factors is crucial for military readiness and troop welfare.

Purpose of the Study:

• To analyze the incidence trends and demographic risk factors of exertional rhabdomyolysis among U.S. service members from 2007 to 2011.

Main Methods:

• Retrospective analysis of incident ER episodes in U.S. service members.
• Examination of annual incidence rates and identification of high-risk demographics and units.

Main Results:

• A near doubling of annual ER rates was observed between 2007 and 2011, with 435 episodes in 2011.
• Highest incidence rates were found in males, Black non-Hispanics, individuals under 20, and within the Marine Corps and Army.
• Cases were concentrated at installations supporting recruit training and major combat units.

Conclusions:

• Exertional rhabdomyolysis poses a significant and increasing risk to U.S. service members, especially recruits undergoing intense training.
• Healthcare providers should maintain a high index of suspicion for ER in service members presenting with relevant symptoms, particularly in hot weather conditions.
• Targeted prevention strategies are needed for high-risk populations and training environments to mitigate ER incidence.
