To study the frequency of obstructive sleep apnea (OSA) in individuals of Somali ancestry referred to a clinical sleep laboratory.
This was a retrospective study using a large registry of patients who underwent diagnostic polysomnography between 17 November 2009 and 15 April 2017. Adult patients self-reporting as being of Somali origin were confirmed using the electronic medical record.
Somali-American patients comprised approximately 0.2% of all patients undergoing polysomnography at the Mayo Clinic Center for Sleep Medicine. The median (interquartile range) age was 52.6 (35, 64) years with 66% males and a median (interquartile range) body mass index of 31.2 (27, 34) kg/m². OSA was diagnosed in 77% of patients, with approximately 50% having moderate to severe OSA. OSA was more frequent in older patients and similar between men and women, and only age predicted an OSA diagnosis while sex and body mass index did not. All patients with diabetes mellitus type 2 (n = 7) and all but one of the hypertensive patients (n = 11) had significant OSA.
Less than 0.2% of all patients undergoing polysomnography at Mayo Clinic were of Somali origin. Moderate-to-severe OSA was frequent in this select sample of individuals who underwent polysomnography. Hypertension and diabetes were present in most Somali-Americans with OSA. Given the rising prevalence of diabetes and hypertension in Somali-Americans, and the likely high prevalence of undiagnosed OSA, screening Somali-Americans for sleep disorders may contribute importantly to prevention, early detection, and reduction of cardiovascular and metabolic diseases in this population.
研究就诊于临床睡眠实验室的索马里裔个体中阻塞性睡眠呼吸暂停（OSA）的频率。
这是一项回顾性研究，使用了在 2009 年 11 月 17 日至 2017 年 4 月 15 日期间进行诊断性多导睡眠图检查的患者的大型登记处。通过电子病历确认报告为索马里裔的成年患者。
在梅奥诊所睡眠医学中心进行多导睡眠图检查的所有患者中，索马里裔美国人患者约占 0.2%。患者的中位（四分位距）年龄为 52.6（35，64）岁，男性占 66%，中位（四分位距）体重指数为 31.2（27，34）kg/m²。77%的患者诊断为 OSA，其中约 50%为中重度 OSA。OSA 在年龄较大的患者中更为常见，且在男性和女性中相似，只有年龄可预测 OSA 诊断，而性别和体重指数则不能。所有 2 型糖尿病患者（n=7）和几乎所有高血压患者（n=11）均存在严重的 OSA。
在梅奥诊所接受多导睡眠图检查的所有患者中，不到 0.2%的患者来自索马里。在接受多导睡眠图检查的这部分个体中，中重度 OSA 较为常见。在患有 OSA 的索马里裔美国人中，高血压和糖尿病较为常见。鉴于索马里裔美国人中糖尿病和高血压的患病率不断上升，且 OSA 可能未得到诊断，对索马里裔美国人进行睡眠障碍筛查可能会对该人群的预防、早期发现和减少心血管和代谢疾病起到重要作用。
