For women, urinary incontinence and other related lower urinary tract symptoms (e.g. nocturia, urinary urgency, frequency) are common, often increasing in frequency as women age. Urinary incontinence, however, is more than just a physiologic loss of urine. Emotional distress is also a significant issue for incontinent individuals. Researchers and clinicians are increasingly aware of the importance of identifying urinary incontinence and, in particular, urinary incontinence that causes distress or adversely affects health-related quality of life in elderly women. A recent article by Gopal and colleagues  addresses the association of lower urinary tract symptoms with changes in estradiol levels during the menopausal transition.
In this study , a self-administered validated questionnaire to measure lower urinary tract symptoms was administered to 300 premenopausal women as they transitioned to menopause. The association between the change in estradiol levels over time through the menopausal transition and lower urinary tract symptoms (urinary incontinence, filling symptoms, voiding dysfunction) was determined. The authors report that estradiol levels and menopausal stage at one point in time were not associated with lower urinary tract symptoms. Women with a sharp decline in estradiol levels over time had significantly less symptoms in comparison with women without a change in estradiol levels through the study period. Women between the ages of 45 and 49 years had significantly more urinary incontinence symptoms than women older than 55 years. Women with a body mass index greater than 35 also had significantly higher urinary incontinence symptoms than women in the normal weight range, after adjusting for changes of estradiol levels through the menopausal transition. High anxiety was associated with worsening scores in all three lower urinary tract symptom domains (incontinence, filling, voiding). In conclusion, urinary filling symptoms and voiding dysfunction were not associated with changes in estradiol levels through the menopausal transition.
