Urinary incontinence is frequently underreported and underdiagnosed in the clinical setting. We analyzed 12 years of data from a large, nationally representative sample of women in the United States to assess the prevalence, severity, and daily impact of urinary incontinence and its subtypes at the population level.
We analyzed data from 15,003 women aged ≥20 years who participated in the 2005-2016 National Health and Nutrition Examination Survey. We estimated the prevalence of urinary incontinence in the prior year, overall and by subtype (stress, urgency or mixed). Among women with urinary incontinence, we additionally assessed symptom severity using the validated 4-level Incontinence Severity Index, as well as impact on daily activities.
The 2005-2016 prevalence of any urinary incontinence was 53%; 16% of women had mixed urinary incontinence, 26% had stress only and 10% had urgency only. While urgency urinary incontinence and mixed urinary incontinence were highest among women aged ≥60 years, stress urinary incontinence was highest among women aged 40-59 years. NonHispanic Black women had higher prevalence of urgency urinary incontinence and lower prevalence of stress urinary incontinence compared to other racial/ethnic groups. Of women with urinary incontinence, 30% reported moderate or severe symptoms, which were more common among older than younger women. In addition, 24% of women with urinary incontinence reported that the condition affected their daily activities.
Our study demonstrates a high prevalence of urinary incontinence among a nationally representative population of women in the United States, with many reporting that urinary incontinence affected their daily activities. Age and racial/ethnic trends varied by urinary incontinence subtype.
在临床环境中，尿失禁经常被漏报和漏诊。我们分析了来自美国一个大型全国代表性女性样本的 12 年数据，以评估人群水平下尿失禁及其亚型的流行率、严重程度和对日常生活的影响。
我们分析了 2005 年至 2016 年参加全国健康和营养调查的 15003 名年龄≥20 岁女性的数据。我们估计了过去一年的尿失禁患病率，总体患病率和各亚型（压力性、急迫性或混合性）的患病率。在患有尿失禁的女性中，我们还使用经过验证的 4 级尿失禁严重程度指数评估了症状严重程度，以及对日常生活活动的影响。
2005-2016 年任何类型尿失禁的患病率为 53%；16%的女性患有混合性尿失禁，26%的女性仅有压力性尿失禁，10%的女性仅有急迫性尿失禁。虽然急迫性尿失禁和混合性尿失禁在≥60 岁的女性中发病率最高，但压力性尿失禁在 40-59 岁的女性中发病率最高。与其他种族/族裔群体相比，非西班牙裔黑人女性急迫性尿失禁的患病率较高，而压力性尿失禁的患病率较低。在有尿失禁的女性中，30%报告有中度或重度症状，且年龄较大的女性比年龄较小的女性更常见。此外，24%的尿失禁女性报告称，该疾病影响了她们的日常生活活动。
我们的研究表明，在美国具有代表性的女性人群中，尿失禁的患病率很高，许多女性报告称尿失禁影响了她们的日常生活活动。年龄和种族/族裔趋势因尿失禁亚型而异。
