Urinary Incontinence (UI)：Urinary incontinence will be diagnosed according to the definition of the International Continence Society (ICS), that is, 'any involuntary leakage of urine'. In addition, participants must have experienced this symptom continuously for at least six months to exclude cases of transient urinary incontinence.\n\n2\\. Stress Urinary Incontinence (SUI)：The clinical diagnosis of SUI will be made with reference to the guidelines of the European Association of Urology (EAU) and the International Continence Society (ICS):\n\n1. Symptoms: Involuntary leakage of urine during activities that increase intra-abdominal pressure, such as physical exertion, laughing, coughing, or walking; urine leakage stops immediately when the activity ceases.\n2. Signs: Positive result on the cough stress test or a positive 1-hour pad test (the procedure will follow the standardized ICS protocol; leakage \\>1g is considered positive).\n3. Pure urge incontinence and mixed urinary incontinence will be excluded. This subtype will be preliminarily identified using the Chinese version of the \"3 Incontinence Questions\" (3IQ): \"During the past three months, in which of the following situations did you most often experience urine leakage? (single choice) A. During physical activities such as coughing, sneezing, lifting, or exercise; B. When you had the urge to urinate or felt the need to empty your bladder but could not reach the toilet in time; C. Without physical activity or urge; D. Equally during physical activity and urgency.\" (Selection of option A) SUI will be finally confirmed by a one-week bladder diary (showing only stress-related leakage) and a positive 1-hour pad test.\n\n3\\. Urge Urinary Incontinence (UUI)：The clinical diagnosis of UUI will follow the guidelines of the European Association of Urology (EAU) and the International Continence Society (ICS):\n\n1. Symptoms: Involuntary leakage of urine accompanied by or immediately preceded by urgency (a sudden, compelling desire to void that is difficult to defer).\n2. Cases of pure stress urinary incontinence and mixed urinary incontinence will be excluded.\n\nThis subtype will be preliminarily identified using the Chinese version of the \"3 Incontinence Questions\" (3IQ): \"During the past three months, in which of the following situations did you most often experience urine leakage? (single choice) A. During physical activities such as coughing, sneezing, lifting, or exercise; B. When you had the urge to urinate or felt the need to empty your bladder but could not reach the toilet in time; C. Without physical activity or urge; D. Equally during physical activity and urgency.\" (Selection of option B) Final confirmation will be based on a one-week bladder diary recorded by the participant (showing only urgency-related leakage).\n\n4\\. Mixed Urinary Incontinence (MUI)：The clinical diagnosis of MUI will follow the guidelines of the European Association of Urology (EAU) and the International Continence Society (ICS):\n\n1. Symptoms: The presence of stress urinary incontinence symptoms, such as involuntary leakage of urine during activities that increase intra-abdominal pressure (e.g., exercise, laughing, coughing, walking), with urine flow ceasing immediately upon stopping the activity; and, at the same time, the presence of urge urinary incontinence symptoms, such as urgency (a sudden, compelling desire to void that is difficult to defer) accompanied by or immediately followed by involuntary leakage of urine.\n2. Signs: Positive result on the cough stress test or a positive 1-hour pad test (the procedure will follow the standardized protocol of the ICS; leakage \\>1g is considered positive).\n3.

The overall objection is to address the gaps in epidemiological profiles, TCM syndrome differentiation, and biomarkers discovery of urinary incontinence among older women. The specific aims including:\n\n1. To assess the epidemiological characteristics of urinary incontinence among older women, as well as patients' knowledge and healthcare-seeking barriers, and to explore factors influencing the disease subtypes, severity, and healthcare-seeking behaviors;\n2. To establish diagnostic criteria for traditional Chinese medicine (TCM) syndrome differentiation of urinary incontinence, and analyze the distribution of TCM syndromes;\n3. To explore diagnostic biomarkers and severity evaluation biomarkers for three subtypes of urinary incontinence (SUI, UUI, MUI).",[56],"Urinary Incontinence in Old Age",[58,59],"urinary incontinence","female","NOT_YET_RECRUITING","2025-11-17",{"date":63,"type":64},"2025-11-21","ACTUAL",{"date":66,"type":52},"2025-11-30",{"date":68,"type":52},"2027-03-01",{"name":5,"class":6}]
