Lignans phytoestrogens are currently found in a variety of plant foods, including flaxseed, sesame, legumes, whole grains, fruits and vegetables. The isoflavone phytoestrogen class is found primarily in soybeans and soy products. The study analyzed 4,104 women who participated in the National Health and Nutrition Examination Survey (NHANES) between 2000 and 2010 and found that increased concentrations of the lignans phytoestrogens enterodiol and enterolipid were both significantly associated with urge incontinence, incontinence anxiety and a decreased likelihood of impact on daily life. dr. Kreydin added that increased concentrations of enterodiol were associated with Dr. Kreydin added that increased intestinal diol concentrations were significantly associated with a decreased likelihood of “other types of urinary incontinence”. The ratios per unit change in urinary enterodiol and enterolipid concentrations for urge incontinence, other types of incontinence, incontinence anxiety, and incontinence impact on daily activities were 0.43, 0.49, 0.32, 0.14, and 0.47, 0.32, 0.30, 0.24, respectively. In addition, this study also found that isoflavone phytoestrogens were not associated with a reduction in urinary symptoms. In fact, one of the isoflavone phytoestrogens – genistein – was associated with an increased likelihood of urinary incontinence (ratio, 2.45). Subjects in this study completed a urinary function test and quality of life questionnaire and underwent urinary phytoestrogen level measurement. Urinary symptoms were assessed after adjusting for factors including age, race, smoking status, body mass index, diabetes, number of births, and menopausal status that are known to influence lower urinary tract symptoms in women.
