Summary
This study links vitamin and joint health supplement use in military personnel to specific medical diagnoses. Higher supplement usage correlated with nervous system, musculoskeletal, and injury-related conditions.
Area of Science:
- Nutritional Science
- Military Health
- Epidemiology
Background:
- Dietary supplement (DS) use is prevalent but associations with medical diagnoses in active duty military personnel are not well understood.
- Previous studies often rely on self-reported use or adverse event reports, lacking linkage to objective medical data.
- Understanding DS use patterns and their health implications in military populations is crucial for readiness and well-being.
Purpose of the Study:
- To investigate the association between survey-reported dietary supplement use and medical record diagnoses in US Navy and Marine Corps active duty personnel.
- To compare dietary supplement usage in military personnel with the general US population.
- To establish a foundation for future longitudinal studies on DS use in this demographic.
Main Methods:
- A cross-sectional study involving a one-time survey of DS use among active duty personnel.
- Matching survey data with International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) diagnostic codes from the Military Health System Data Repository (MDR).
- Utilizing multivariable logistic regression analyses to examine associations between specific supplement classes and diagnosed diseases, with a stringent statistical significance level (alpha=0.005).
Main Results:
- Vitamin supplement use was significantly associated with diagnosed diseases of the nervous system (OR: 1.72) and musculoskeletal system (OR: 1.59).
- Joint health supplement use showed associations with musculoskeletal diseases (OR: 1.81) and injury/poisoning (OR: 1.82).
- A higher prevalence of weekly DS use (73%) was observed in surveyed military personnel compared to the general population (estimated 50%).
Conclusions:
- Dietary supplement use, particularly vitamins and joint health supplements, is linked to specific health conditions within the active duty military population.
- The prevalence of dietary supplement use is higher among US Navy and Marine Corps personnel than in the general US population.
- Longitudinal studies are recommended to further explore these associations and inform health policies for military service members.

9.8K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

In biological systems, most metabolic pathways are interconnected. The cellular respiration processes that convert glucose to ATP—such as glycolysis, pyruvate oxidation, and the citric acid cycle—tie into those that break down other organic compounds. As a result, various foods—from apples to cheese to guacamole—end up as ATP. In addition to carbohydrates, food also contains proteins and lipids—such as cholesterol and fats. All of these organic compounds are used...

The Nursing Code of Ethics sets the ethical benchmark for the profession, and guides nurses in ethical analysis and decision making at the societal, organizational, and clinical levels. The code encompasses showing compassion and respect for the patient, their families, and communities in all circumstances while committing to providing patient-centered care. In addition, the code states that nurses must advocate for the patient by defending a cause or recommendation to protect their rights,...

Consuming animal-based products offers high-quality proteins that contain optimal levels and combinations of essential amino acids, crucial for tissue repair and growth. Foods like eggs, milk, fish, and most meats are a source of complete proteins. Legumes and cereals are abundant in proteins; however, they typically lack a full range of essential amino acids. As a result, they are considered incomplete protein sources. Some plant sources like soybeans, quinoa, and amaranth do contain complete...

Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...
