背景：银屑病是一种慢性炎症性疾病，与显著的发病率和死亡率相关。银屑病的最新患病率数据为人口研究、教育和卫生政策提供了基础。目的：我们试图确定美国成年人银屑病的患病率。方法：我们使用2009年至2010年国家健康和营养调查数据进行了一项横断面研究，以确定银屑病患病率。结果：在6218名20岁以上的参与者中，6216名受访者提供了关于银屑病诊断的完整信息。美国20岁及以上成年人中银屑病的患病率为3.2%（95%置信区间[CI] 2.6%-3.7%）。2010年共有720万美国成年人患有银屑病; 2013年估计有740万美国成年人受到影响。当对20 - 59岁的人群进行种族分层时，白种人的银屑病患病率最高，为3.6%。（95% CI 2.7%-4.4%），其次是非洲裔美国人（1.9%; 95% CI 1.0%-2.8%）、西班牙裔美国人（1.6%; 95% CI 0.5%-2.8%）和其他（1.4%; 95% CI 0.3%-2.6%）。自2003年至2004年，美国成年人银屑病的患病率没有显著变化（P > .05）。局限性：2009年至2010年的调查中没有皮肤科医生的评估和皮肤照片。结论：在美国，银屑病仍然是一种常见的免疫介导的疾病，影响740万成年人。自2000年代中期以来，其流行率一直保持稳定。
Background: Psoriasis is a chronic inflammatory disorder associated with significant morbidity and mortality. Up-to-date prevalence data on psoriasis provide the foundation for informing population research, education, and health policy.Objective: We sought to determine the prevalence of psoriasis among US adults.Methods: We performed a cross-sectional study using National Health and Nutrition Examination Survey 2009 through 2010 data to determine psoriasis prevalence rates.Results: From 6218 participants older than 20 years of age, 6216 respondents provided complete information regarding a psoriasis diagnosis. The prevalence of psoriasis among US adults ages 20 years and older is 3.2% (95% confidence interval [CI] 2.6%-3.7%). A total of 7.2 million US adults had psoriasis in 2010; an estimated 7.4 million US adults were affected in 2013. When stratifying the sample by race among those between ages 20 and 59 years, the psoriasis prevalence was highest in Caucasians at 3.6% (95% CI 2.7%-4.4%), followed by African Americans (1.9%; 95% CI 1.0%-2.8%), Hispanics (1.6%; 95% CI 0.5%-2.8%), and others (1.4%; 95% CI 0.3%-2.6%). The prevalence of psoriasis among US adults has not changed significantly since 2003 to 2004 (P > .05).Limitations: Dermatologist evaluation and skin photographs were unavailable for the 2009 through 2010 surveys.Conclusions: In the United States, psoriasis remains a common, immune-mediated disease, affecting 7.4 million adults. Its prevalence has remained stable since the mid-2000s.
