Pelvic Floor Disorders Among U.S. Military Active-Duty Females.

Importance: Women are a growing cohort within the U.S. military. Pelvic floor health is a component of health maintenance for which support needs vary by sex. The American Journal of Obstetrics & Gynecology reports that 1 in 4 women is affected by moderate to severe pelvic floor dysfunction (PFD). Understanding the specific experience of female service members is warranted for health care optimization and preservation of force readiness.

Objective: We aimed to identify the prevalence, incidence, and risk factors associated with incident PFD in active-duty females during an 11-year window.

Study design: We used the Medical Assessment and Readiness System at Womack Army Medical Center, which includes medical record and personnel data from 2011 to 2022. Pelvic floor dysfunction diagnoses were identified using diagnosis codes and analyzed with respect to demographic parameters.

Results: Between 2011 and 2022, 32,996 of 550,303 active-duty females were diagnosed with PFD (period prevalence: 6.00%). Using 2011-2012 as a washout period, 27,046 of 486,558 participants were diagnosed during 1,879,990.90 person-years of follow-up (incidence rate: 14.39 cases per 1,000 person-years). The incidence rate of PFD increased in both new and established active-duty females. Increasing time since service entry was the strongest, statistically significant independent predictor of PFD. Three or more deployments and specific physical fitness scoring were also predictors of PFD.

Conclusions: The incidence rate of PFD among female service members is increasing, and multiple military-specific factors predict PFD. As the percentage of women in active-duty service continues to grow, additional investigation is needed to confirm PFD trends, illuminate other predictors, and prevent adverse outcomes.
