Bacteriuria and subsequent mortality in women

Area of Science:

• Urology
• Epidemiology
• Gerontology

Background:

• Bacteriuria is common in women and has been linked to various health outcomes.
• Understanding the long-term mortality risk associated with bacteriuria is crucial for public health.

Purpose of the Study:

• To investigate the association between bacteriuria and subsequent mortality in a population-based cohort of women.
• To determine if persistent bacteriuria confers a higher mortality risk.

Main Methods:

• Population-based cohort study involving women in Jamaica and Wales over a 13-year period.
• Three surveys were conducted, with bacteriuria defined as >= 10(5) gram-negative bacilli/mL in three consecutive urine cultures over 3 weeks.
• Mortality data was collected at the second and third surveys, with analyses adjusted for age and weight.

Main Results:

• Bacteriuria was significantly associated with increased mortality in both crude and adjusted analyses.
• Women bacteriuric at the first survey had a 1.5-fold increased risk of death by the third survey.
• Women with persistent bacteriuria at the first two surveys showed the highest adjusted risk ratio for death (2.0) between the second and third surveys.

Conclusions:

• Bacteriuria is a significant risk factor for subsequent mortality in women.
• Persistent bacteriuria is associated with a substantially elevated risk of death.
• These findings underscore the importance of monitoring and managing bacteriuria in women, particularly in older populations.
