Is pH a vaginal health marker? Phemale Study

Area of Science:

• Gynecology
• Epidemiology
• Women's Health

Background:

• Limited epidemiological data exists on vaginal pH levels in the Spanish female population.
• This study aimed to establish the physiological pattern of vaginal pH in Spanish women.
• Key factors examined included body mass index, physical activity, employment, contraceptive use, sexual activity, and symptoms.

Purpose of the Study:

• To confirm the physiological patterns of vaginal pH in Spanish women.
• To investigate associations between vaginal pH and various lifestyle and health factors.

Main Methods:

• A cross-sectional study involving 2136 healthy women over 18 years old.
• Vaginal pH was measured using specialized testing kits.
• Statistical analysis included Spearman's correlation and ANOVA.

Main Results:

• Mean vaginal pH varied by age group, with notable increases in older age brackets.
• No correlation was found between vaginal pH and body mass index or recent sexual activity.
• Lower vaginal pH was observed in women who engaged in physical activity and used contraceptives.
• Higher vaginal pH values were significantly associated with the presence of clinical vaginal symptoms (P<0.01).

Conclusions:

• The study validates typical vaginal pH changes in Spanish women.
• Physical activity and contraceptive use correlate with lower vaginal pH.
• Elevated vaginal pH is linked to vulvo-vaginal symptoms, indicating its role as a vaginal health indicator.
