To estimate the frequency of symptoms of obesity hypoventilation syndrome (OHS) in patients with obstructive sleep apnoea (OSA) and to evaluate comorbidities associated with OHS.
Retrospective study based on patients' medical records and on further sleep tests performed in the study centre during the inclusion visit.
Respiratory Care Unit and Sleep Disorder Centre of the Zayed Military Hospital United Arab Emirates.
All patients referred to the study centre for a suspicion of sleep-disordered breathing.
Prevalence of OSA and OSA + OHS and comorbidities in patients with OSA and OHS.
A total of 212 adult patients participated in the study. Of these, 107 patients (50.5% [43.8-57.1% CI 95%]) fulfilled diagnostic criteria for OSA, and the majority were men (79.4%). Among patients with OSA, 18 patients (16.8% [10.8-25.1% CI 95%]) fulfilled diagnostic criteria for OHS. In this group, women were more frequently affected than men (31.8% [7/22] vs. 12.9% [11/85], respectively; p = 0.03) and tended to be older than affected men, with a mean age of 55 ± 10.6 years versus 46 ± 13 for men. After adjustment for gender, OHS was significantly associated with hypertension (OR = 3.5; p = 0.03), diabetes mellitus (OR = 4.6; p = 0.02), ischaemic heart disease (OR = 5.1; p = 0.04) and pulmonary hypertension (OR = 16.1; p = 0.001).
OHS is a common condition in obese patients in the UAE and is associated with an increased risk of cardiovascular comorbidities and diabetes.
评估阻塞性睡眠呼吸暂停（OSA）患者中肥胖低通气综合征（OHS）症状的发生频率，并评估与OHS相关的合并症。
基于患者病历及在纳入研究访视期间于研究中心进行的进一步睡眠测试的回顾性研究。
阿拉伯联合酋长国扎耶德军事医院呼吸护理科及睡眠障碍中心。
所有因疑似睡眠呼吸障碍而转诊至研究中心的患者。
OSA、OSA + OHS的患病率以及OSA和OHS患者的合并症。
共有212名成年患者参与了该研究。其中，107名患者（50.5% [43.8 - 57.1%，95%置信区间]）符合OSA诊断标准，且大多数为男性（79.4%）。在OSA患者中，18名患者（16.8% [10.8 - 25.1%，95%置信区间]）符合OHS诊断标准。在这组患者中，女性比男性更易受影响（分别为31.8% [7/22] 对12.9% [11/85]；p = 0.03），且受影响女性的年龄往往比男性大，平均年龄为55 ± 10.6岁，而男性为46 ± 13岁。在对性别进行调整后，OHS与高血压（OR = 3.5；p = 0.03）、糖尿病（OR = 4.6；p = 0.02）、缺血性心脏病（OR = 5.1；p = 0.04）和肺动脉高压（OR = 16.1；p = 0.001）显著相关。
在阿联酋，OHS在肥胖患者中很常见，且与心血管合并症和糖尿病的风险增加相关。
