We report an outbreak of 235 community-acquired methicillin-resistant Staphylococcus aureus (MRSA) infections among military recruits. In this unique environment, the close contact between recruits and the physical demands of training may have contributed to the spread of MRSA. Control measures included improved hygiene and aggressive clinical treatment.

This study evaluated the risk to hearing health associated with duty on the flight deck of a Nimitz class aircraft carrier. Descriptive data includes time-weighted average noise exposure and an evaluation of temporary threshold shift for a group of nonaviator flight deck personnel (FD), and a comparison of accrued permanent threshold shift among three shipboard occupational groups that had been matched for years of military service. The study participants included 76 FD personnel in a high-exposure group, 77 engineers in a moderate-exposure group, and 52 administrative personnel who were considered to have low occupational noise exposure. The study found a mean FD time weighted average of 109 dBA over workdays averaging 11.5 hours. Only 2 (4%) of 52 administrative personnel had any appreciable hearing loss (defined as worse than 20 dB at any frequency 1,000 through 4,000 Hz), whereas FD and engineers demonstrated 17% and 27% hearing impairment, respectively.

Physical performance and risk factors from the U.S. Navy physical readiness test (PRT) were analyzed in a retrospective, cross-sectional, population-based study using data from the Spring 2002 cycle. PRT scores were available for 22,314 active duty women and 131,287 men, and risk factor information was available for 4,254 women and 31,503 men. For risk factors, self-reported smoking rates were higher for men than women, and decreased with increasing age. Self-reported rates for elevated cholesterol and joint problems increased with increasing age. Linear regression showed body mass index increased with age for men (constant = 25.6, increasing 0.0,765 per year of age over 18 years, p = 0.000) and were increasing at a lower rate for women (constant = 24.5 increasing 0.0,159 per year of age over 18 years, p = 0.000). Increasing body mass index was associated with decreasing PRT performance. This analysis provides population-based information on the PRT risk factors, body mass index, and physical fitness for Navy personnel.

Quality evidence supports these clinical practice recommendations. The guidelines may be useful to providers who diagnose and/or treat WRA.
