Weight loss is one of the first line treatments for people with obstructive sleep apnea (OSA); however, people with OSA may have difficulties losing weight. Few studies have investigated the factors underlying these challenges in people with OSA. The aim of this study was to compare dietary intake, eating behavior and physical activity data in people with OSA and without OSA. Seventy-four patients referred to a sleep disorders clinic for suspected OSA underwent a standard clinical overnight polysomnography and completed questionnaires assessing dietary intake, physical activity and eating behavior prior to treatment. On the Three Factor Eating Questionnaire-R18 patients with OSA ( n = 49, AHI 19.5 [13.0–55.4] events/h) had higher levels of uncontrolled eating (adjusted means, 19.7 (0.7) vs 16.1 (1.0): F (1, 69) = 7.103, p = 0.010 partial η 2 = 0.093), than those who did not have OSA ( n = 25, AHI 3.3 [0.8–4.4] events/h) after adjusting for age, fat mass % and depression. There were no differences between groups in dietary intake measures or physical activity. These results suggest that people with OSA may need specific attention to eating behavior when undergoing weight loss interventions.

患有和不患有阻塞性睡眠呼吸暂停的个体的膳食摄入量、饮食行为和身体活动

减肥是阻塞性睡眠呼吸暂停 (OSA) 患者的一线治疗方法之一；然而，患有 OSA 的人可能难以减肥。很少有研究调查 OSA 患者面临这些挑战的潜在因素。本研究的目的是比较 OSA 和非 OSA 患者的饮食摄入、饮食行为和身体活动数据。74 名因疑似 OSA 转诊至睡眠障碍诊所的患者在治疗前接受了标准的临床过夜多导睡眠图并完成了评估饮食摄入、身体活动和饮食行为的问卷调查。在三因素饮食问卷 - R18 中，OSA 患者（n = 49，AHI 19.5 [13.0–55.4] 个事件/小时）具有更高水平的不受控制的饮食（调整后的平均值，19.7 (0.7) vs 16.1 (1.0)：F (1 , 69) = 7.103, p = 0.010 部分 η 2 = 0。093)，而不是那些没有 OSA 的人（n = 25，AHI 3.3 [0.8-4.4] 个事件/小时），在调整年龄、脂肪质量百分比和抑郁后。在饮食摄入量或身体活动方面，各组之间没有差异。这些结果表明，OSA 患者在进行减肥干预时可能需要特别注意饮食行为。
