It is crucial to understand the racial and ethnic disparities that exist in nocturia prevalence to appropriately manage nocturia.
Nocturia is associated with increased body mass index (BMI) and is most prevalent in Black and Hispanic women, who also have the highest and second highest prevalence of obesity, respectively. We sought to better understand the association of nocturia with BMI category by race and ethnicity in U.S. women.
This was a cross-sectional study using publicly available data from the National Health and Nutrition Examination Survey data from 2005 to 2018. We estimated the prevalence of moderate to severe nocturia (defined as 2 or more episodes of nighttime urination) by BMI category within each racial and ethnic (Black, White, Hispanic, and other) group of adult women. Logistic regression was performed to determine the odds ratio of nocturia by race.
The odds of nocturia was 2.25 (2.04-2.49) for Black women, 1.27 (1.15-1.4) for Hispanic women and 0.96 (0.82-1.13) for other women compared to White women. After accounting for BMI, socioeconomic status and comorbidities, the adjusted odds ratio was 1.76 (1.42-2.16) for Black women, 1.1 (.0.88-1.38) for Hispanic women, and 0.81 (0.5-1.29) for other women compared to White women.
Black women were nearly twice as likely to have nocturia than White women. The increased odds of nocturia, while not sustained for Hispanic women, persisted for Black women regardless of socioeconomic status, BMI, and comorbidities. Our study suggests that there are factors other than weight driving the prevalence of nocturia in Black women that require further investigation.
了解夜尿症患病率中存在的种族和民族差异对于适当管理夜尿症至关重要。
夜尿症与体重指数（BMI）升高有关，在黑人女性和西班牙裔女性中最为普遍，她们的肥胖患病率分别也是最高和第二高。我们试图更好地了解美国女性中按种族和民族划分的夜尿症与BMI类别之间的关联。
这是一项横断面研究，使用了2005年至2018年国家健康和营养检查调查的公开数据。我们估计了成年女性每个种族和民族（黑人、白人、西班牙裔和其他）组内按BMI类别划分的中度至重度夜尿症（定义为夜间排尿2次或更多次）的患病率。进行逻辑回归以确定按种族划分的夜尿症优势比。
与白人女性相比，黑人女性患夜尿症的优势比为2.25（2.04 - 2.49），西班牙裔女性为1.27（1.15 - 1.4），其他女性为0.96（0.82 - 1.13）。在考虑BMI、社会经济地位和合并症后，与白人女性相比，黑人女性的调整后优势比为1.76（1.42 - 2.16），西班牙裔女性为1.1（0.88 - 1.38），其他女性为0.81（0.5 - 1.29）。
黑人女性患夜尿症的可能性几乎是白人女性的两倍。夜尿症优势比的增加，虽然西班牙裔女性的情况并非持续如此，但无论社会经济地位、BMI和合并症如何，黑人女性的情况仍然存在。我们的研究表明，除了体重之外，还有其他因素导致黑人女性夜尿症患病率较高，这需要进一步调查。
