Summary
Disordered eating (DE) is linked to increased musculoskeletal injury (MSK-I) risk in female Marine officers. This highlights a critical health concern for military women, underscoring the need for targeted interventions and further research.
Area of Science:
- Military Health
- Sports Medicine
- Eating Disorders Research
Background:
- Active duty service members (ADSMs) face risks for eating disorders (EDs) and musculoskeletal injuries (MSK-I).
- High physical demands in military training may exacerbate these risks.
- Understanding the link between disordered eating (DE) and MSK-I in ADSMs is crucial.
Purpose of the Study:
- To determine the prevalence of DE among Marine Corps officers.
- To investigate the association between DE and recent MSK-I in this population.
- To explore potential sex differences in the DE-MSK-I relationship.
Main Methods:
- Cross-sectional study within the IMPACT study.
- Participants: 1,382 Marine Corps officers.
- Measures: Eating Disorder Examination-Questionnaire Short (EDE-QS) for DE, self-reported recent MSK-I.
- Analysis: Logistic regression adjusted for covariates.
Main Results:
- 7% of officers reported elevated DE (EDE-QS ≥15).
- 18.3% reported recent MSK-I.
- Elevated DE was associated with increased MSK-I odds in females (aOR=1.35), but not in males.
- Females had higher odds of MSK-I than males (aOR=1.17).
Conclusions:
- Disordered eating is associated with higher odds of recent MSK-I specifically in female Marine officers.
- Findings align with research on female athletes, suggesting a link between DE and skeletal health.
- Further prospective research is needed to establish causality.

The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

46
Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...

01:28Anorexia Nervosa
43
Anorexia nervosa is a complex and severe eating disorder characterized by an intense fear of weight gain, an unrelenting pursuit of thinness, and a distorted body image. It often leads to dangerously low body weight relative to an individual's age and height. This disorder is marked by significant physical and psychological consequences, making it one of the most life-threatening psychiatric illnesses.

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:22The Functions of the Skeletal System
3.5K
The most apparent functions of the skeletal system are support, protection, and movement. However, bone tissue also performs several other critical metabolic functions. For one, the bone matrix acts as a reservoir for a number of minerals important to the functioning of the body, especially calcium and phosphorus. These minerals, present in the bone tissue, can be released back into the bloodstream when required. Calcium ions, for example, are essential for muscle contractions and controlling...

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
