The Effect of a Sharp Increase in Estrogen Levels on Overactive Bladder Symptoms in Women Undergoing Ovulation Induction

Associations Between Serum Estrogen Levels and Urinary Incontinence in Women: A Cross-sectional Analysis of NHANES 2013 to 2016

OBJECTIVE

To explore the relationship between serum estrogen levels and urinary incontinence in a nationally representative female population.

MATERIALS AND METHODS

We included women who had serum estradiol measurements and self-reported urinary incontinence problems in the 2013-2016 National Health and Nutrition Examination Survey cycles. A weighted multivariable logistic regression model was used to determine the association between urinary incontinence and serum estrogen levels after adjusting for age, race, Body Mass Index, diabetes, venipuncture, hypertension, poverty-to-income ratio, smoking, marital status, alcohol use, education, and menopause.

RESULT

A total of 4114 individuals were ultimately included in our study. Of these women, 1200 (29.17%) complained of urge urinary incontinence (UUI), 1674 (40.69%) complained of stress urinary incontinence (SUI), 730 (17.74%) complained of mixed urinary incontinence (MUI). Women in the lowest quartile of serum estrogen were more likely to complain of UUI compared to those in the highest quartile (OR=1.885; 95% CI=1.042-3.412, P = .039). No association was noted between serum estrogen levels and SUI or MUI.

CONCLUSION

Our study shows a significant association between low serum estrogen level and the increased likelihood of UUI in women. Further research is required to validate our findings, elucidate the physiological mechanisms that underlie them, and assess potential therapeutic implications.
