Bacterial Urinary Tract Infection
Conditions
Brief summary
The purpose of this study is to assess nutrition and urinary tract bacterial activity during menstruation of approximately 15 female university Reserve Officer Training Corps (ROTC) cadets and Phoenix area police officers, firefighters, and military veterans.
Detailed description
Urinary tract infections (UTIs) disrupt tactical service women's obligations and health, which increases sexual transmitted infections (STIs), HPV, and cervical cancer risk if left untreated. Females are more susceptible to UTIs due to their unique anatomical features and hormone fluctuations affecting vaginal flora. During phase 1 of the menstrual cycle (i.e., onset of bleeding, menstrual cycle days 1-5), estrogen levels significantly decrease and inhibit the growth of lactobacilli (good bacteria), which is essential in warding off bad bacteria and infections, particularly UTIs. The uropathogenic bacterial growth in phase 1 could be heightened in phase 2 of the menstrual cycle (i.e., leading to ovulation), as increases in estrogen favors bacteria adhesion and arginine vasopressin (AVP) release that stimulates fluid retention, leading to less volume flow in the urinary tract. To reduce UTI onset, it is recommended to frequently urinate with sufficient urine void volume to facilitate washing out harmful bacteria from the urethra and bladder. While menstruating, increased fluid consumption to support urination frequency and void volume may be critical, as the urinary tract is more predisposed to infections, and the effects of estrogen on bacterial adhesion and AVP release in phase 2 could continue uropathogenic growth. Question(s) 1: Are premenopausal tactical service women's current hydration status and behaviors (i.e., fluid intake and urination) sufficient? How many premenopausal tactical service women have a UTI history? Question 2: Will increasing daily water intake of identified underhydrated tactical service women reduce uropathogenic bacterial activity during the first part (i.e., onset of bleeding through day 5) of the menstrual cycle?
