Background

Urinary incontinence is one a lower urinary tract disorder prevalent in women of reproductive age. The role of vitamin D in urinary incontinence has not been proven, despite extensive study.

Objectives

This study aimed to investigate the relationship between serum 25(OH)D levels with urinary incontinence in Iranian reproductive-aged women.

Material and methods

This cross-sectional study was conducted on 437 samples of women aged 15–49 years who complained about any urinary tract disease and were referred to two comprehensive health centres in Izeh, Iran, from May to September 2017. Serum 25(OH)D was assessed using High-Performance Liquid Chromatography after 8–12 hours of fasting. The severity of urinary incontinence was measured using the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-UISF) and was confirmed by a gynaecologist.

Results

The serum levels of 25(OH)D in UI patients were significantly lower than the comparative group (p < 0.05). The association between vitamin D levels and UI subgroups was significantly positive (p = 0.001). Vitamin D also had a negative coefficient of correlation (-0.096) with the severity of urinary incontinence (p = 0.001).

Conclusions

There was a significant relationship between serum 25(OH)D levels and the severity of urinary incontinence among Iranian reproductive-aged women. A low serum 25(OH)D level is also significantly related to UI subgroups.
