Prevalence of Urogenital Mycoplasma genitalium Infection at 2 US Army Medical Facilities.

BACKGROUND: Sexually transmitted infections (STIs) have a high incidence in the US Armed Forces and can adversely impact service members' ability to perform their duties. Better knowledge of Mycoplasma genitalium (MG) epidemiology in the military is needed to understand the potential impact of this emerging pathogen on force readiness. METHODS: We conducted cross-sectional analyses of data from US Army service members and other Military Health System beneficiaries participating in a trial of an STI/HIV behavioral intervention at Fort Liberty, NC, and Joint Base Lewis-McChord, WA. At enrollment, participants completed questionnaires and provided biological specimens for nucleic acid amplification testing for MG, Chlamydia trachomatis (CT), and Neisseria gonorrhoeae (NG). We used principal component analysis and robust Poisson regression to examine associations between participant characteristics and prevalent urogenital MG. RESULTS: Among 432 participants enrolled between November 2020 and February 2023, 43 had MG (prevalence, 10.0%), of whom 13 had coinfection with another bacterial STI (all 13 were positive for CT, with 1 also positive for NG). The prevalence of MG was significantly higher among female (13.5%) versus male (7.6%; P = 0.048) participants and non-Hispanic Black (14.9%) versus non-Hispanic White participants (6.6%; P = 0.045). Single relationship status and increased number of recent sexual partners were correlated, and their component was associated with higher MG prevalence (adjusted prevalence ratio, 2.11; 95% confidence interval, 1.29-3.48). CONCLUSIONS: The high prevalence of urogenital MG among Military Health System beneficiaries highlights the importance of understanding the potential clinical sequelae of MG and conducting additional epidemiologic research in military settings.

Knowledge and Attitudes Regarding Human Papillomavirus Among Active Duty Service Members at a Large Military Base.

OBJECTIVE: To assess gaps in human papillomavirus (HPV) knowledge and current attitudes toward HPV vaccination among active duty soldiers at Fort Bragg, NC, and to evaluate the impact of the instruction intervention on knowledge and attitudes regarding HPV vaccination. METHODS: A six-question assessment was administered to soldiers presenting for appointments through the Epidemiology and Disease Control (EDC) Clinic at Fort Bragg in January 2020. Questions included five multiple choice knowledge assessments and a Likert scale attitude question regarding HPV vaccination. The assessment was administered before and after a one-on-one educational intervention conducted by the EDC Clinic nursing staff. Pre- and post-assessments were matched using unique encounter numbers. RESULTS: A total of 139 matched pre- and post-education assessments were completed. Statistically significant changes in HPV knowledge were observed in test score and percent correct (P < .001). Additionally, for individuals reporting no prior HPV vaccination, attitudes toward receiving it increased from 4 (interquartile range 3-5) to 5 (4-5) following instructions (P < .001). This indicates a shift from moderately interested to very interested. CONCLUSIONS: Results among soldiers demonstrated a lack of knowledge regarding HPV infection, its long-term effects, and preventive measures available among this population of active duty members. Assessment results also illustrated education about HPV infection and vaccination positively impacts soldiers' knowledge and attitudes toward HPV vaccination.
