Sleep：睡眠不足6小时增加患病几率

生物谷报道：往常人们一直认为人每天睡8小时即可，可是最新一项研究结果表明每天睡眠不足6小时将大大增加患病几率。

5月1日的《睡眠》（Sleep）杂志上刊登了匹兹堡大学医学院的研究结果，每晚睡眠时间不足6小时的人患心脏病的几率将是睡足6小时者的2倍。不仅如此，缺少睡眠还会大大提高患高血脂、高血压以及肥胖症的几率。研究人员在对1214名成年人进行调查后发现，与心脏病有关的症状会受到睡眠时间的影响。该学院精神病学副教授玛蒂卡·霍尔说，这种关系在每晚睡眠时间低于6小时的参与者中表现得最为明显。

有意思的是，这项研究同时发现，睡眠时间过长的人同样会出现类似症状。与睡眠时间过短或者过长的人相比，每晚睡眠时间在7—8小时的人出现这些健康问题的可能性要低45%。研究人员认为，在几十年内都没有正常睡眠的年轻女性，因心脏病导致的死亡率已经呈现出上升趋势。（生物谷ww.bioon.com）

Study objective:

Short and long sleep duration have been linked to various risk factors for cardiovascular disease. In the present study, we evaluated the relationship between sleep duration and presence of the metabolic syndrome, which is a cluster of physiologically interrelated risk factors for cardiometabolic disease.

Design/Setting:

Cross-sectional community-based cohort study.

Participants:

One thousand two hundred fourteen participants from the Adult Health and Behavior Project registry (aged 30 to 54 years).

Measurements:

Participants were divided into 4 groups based upon their reported sleep duration. The metabolic syndrome was defined according to the American Heart Association/National Heart Lung and Blood Institute’s criteria. Logistic regression was used to test the hypothesis that sleep duration is a significant correlate of the metabolic syndrome and its components.

Results:

The observed metabolic syndrome rate (22%) was similar to that of published health statistics for American adults.
