The hospitalization rate in 2021 was 48.0 per 1,000 person-years (p-yrs), the second lowest rate of the most recent 10 years. For hospitalizations limited to military facilities, the rate in 2021 was the lowest for the entire period. As in prior years, the majority (71.2%) of hospitalizations were associated with diagnoses in the categories of mental ...

In 2021, the overall numbers and rates of active component service member ambulatory care visits were the highest of any of the last 10 years.

Tick-borne Encephalitis in Military Health System Beneficiaries, 2012–2021. Tick-borne encephalitis (TBE) is a viral infection of the central nervous system that is transmitted by the bite of infected ticks, mostly found in wooded habitats in parts of Europe and Asia

Data from surveys may be used to make public health decisions at both the installation and the Department of the Army level. This study demonstrates that a vast majority of soldiers were likely sufficiently engaged and answered both bogus items correctly. Future surveys should continue to investigate careless responding to ensure data quality in ...

This report summarizes incidence rates of the 5 most common sexually transmitted infections (STIs) among active component service members of the U.S. Armed Forces during 2013–2021.

Exertional (or exercise-associated) hyponatremia refers to a low serum, plasma, or blood sodium concentration (below 135 mEq/L) that develops during or up to 24 hours following prolonged physical activity. Acute hyponatremia creates an osmotic imbalance between fluids outside and inside of cells.

Exertional heat illness (hereafter referred to as heat illness) spans a spectrum from relatively mild conditions such as heat cramps and heat exhaustion, to more serious and potentially life-threatening conditions such as heat injury and exertional heat stroke (hereafter heat stroke).

Exertional rhabdomyolysis is a potentially serious condition that requires a vigilant and aggressive approach. Some service members who experience exertional rhabdomyolysis may be at risk for recurrences, which may limit their military effectiveness and potentially predispose them to serious injury.

From 2020 to 2021, the rate of incident heat stroke was relatively stable while the rate of heat exhaustion increased slightly

SARS CoV-2 and the illness it causes, COVID-19, have exacted a heavy toll on the global community. Most of the identified disease has been in the elderly and adults. The goal of this analysis was to ascertain if user-built ESSENCE queries applied to records of outpatient MHS health care encounters are capable of detecting MIS-C cases that have not ...

Osteoarthritis (OA) is the most common adult joint disease and predominantly involves the weight-bearing joints. This condition, including spondylosis (OA of the spine), results in significant disability and resource utilization and is a leading cause of medical separation from military service.

This study examined monthly prevalence of obesity and exercise in active component U.S. military members prior to and during the COVID-19 pandemic. These results suggest that the COVID-19 pandemic had a small effect on the trend of obesity in the active component U.S. military and that obesity prevalence continues to increase.

Since the official introduction of laser refractive surgery into clinical practice throughout the Military Health System (MHS) in fiscal year 2000, these techniques have been heavily implemented in the tri-service community to better equip and improve the readiness of the U.S. military force.
