- The study aimed to identify prevalent health conditions among Navy divers during their last year of service, using data from 4,623 active-duty divers who separated between 2008 and 2018.
- The analysis revealed that the majority of divers were male, with a mean age of 35, and the most common health issues identified were musculoskeletal diseases, nervous system disorders, and mental health issues.
- The findings highlight a need for targeted health programs due to high rates of specific conditions like joint and back disorders, as well as increased ear-related issues among special warfare divers.
Confined space, limited exercise equipment, rotating shift work and reduced sleep may affect cardiometabolic health in submariners. To test this hypothesis, 53 male U.S.

The primary objective of this study was to determine the efficacy of daily vitamin D supplementation on maintenance of 25-hydroxyvitamin D (25(OH)D) during a 3-month submarine patrol. Submariners were randomly divided into three groups: placebo (n = 16), 1,000 IU/day (n = 20), or 2,000 IU/day (n = 17).

The role of repolarization duration and stability in arrhythmogenesis in men and women with structural heart disease has not been explored.
Objectives: The purpose of this study was to analyze repolarization differences between men and women and their relation to the risk of VT/VF.
