Correlation Between Lower Urinary Tract Infection & Overactive Bladder Revelation and Vaginal PH

Vaginal pH change is known as one of the risk factors for recurrent lower urinary tract infection in female. The objective of this study was to analyze the correlation between lower urinary tract infection & overactive bladder revelation and vaginal pH by age group.

Subjects were schizophrenic out-patients, who fufilled DSM-IV diagnostic criteria, and their families.

This study found a positive correlation between age and vaginal pH(p=0.000). It also found that the contraction of cystitis patients was high in older age group(p=0.035). However, vaginal pH was not a significant factor to the contraction of cystitis(p=0.258). In older age group, the number of overactive bladder patients was higher than that of younger age group(p=0.05), while vaginal pH was not a significant factor to the contraction of overactive bladder(p=0.376).

Diseases that cause lower urinary tract symptom such as overactive bladder and recurrent cystitis increase in proportion to age. Vaginal pH also increases in proportion to age. However, vaginal pH is not a significant factor to the contraction of lower urinary tract symptom when the age is revised.
