Female nurses have a higher prevalence of urinary tract symptoms and infection than other occupations in dialysis units

Abstract

Introduction:  Urinary tract symptoms and infection have been associated with occupational factors that impact hydration habits particularly in women. We compared self-reported urinary symptoms and infection and hydration habits between nurses and other occupations in dialysis units.

Methods:  Cross-sectional study. Participants worked in five nephrology centers in Brazil and answered an online questionnaire comprising questions regarding urinary tract symptoms and infection episodes in the preceding year; data on usual daily beverage intake, urine frequency, and urine color according to a urine color chart were also collected, as well as perceptions of water access and toilet adequacy at work.

Results:  We included 133 women (age=36.9±9.5 years). The self-reported usual daily beverage intake was 6.6±2.9 cups/day (~1320 mL), daily urine frequency was 5.4±2.1, and urine color chart score: 3.0±1.2. Nurses (N=66/49.6%) reported higher prevalence of burning sensation (50 versus 27%; P<0.001), urinary urgency (42 versus 21%; P<0.001), and infection (42% versus 25%; P=0.04) as well as lower liquid intake (6.0±2.6 versus 7.3±3.0 cups/day; P=0.01) than controls. Forty four percent of nurses reported being able to drink when thirsty "always" and "most of the time" versus 93% of the control group.

Conclusion:  Dialysis female nurses reported lower beverage intake and higher prevalence of symptoms and infection than other occupations in the same environment. Interventions to improve hydration can potentially decrease urinary problems in this population.
