摘要: 目的 探究睡眠时间与2型糖尿病发病风险的关系,分析睡眠时间与2型糖尿病发病风险的剂量反应关系。方法 计算机检索PubMed、Web of Science、中国知网、万方数据知识服务平台建库至2015-09-22有关睡眠时间与2型糖尿病发病风险的前瞻性研究,通过文献质量评价后,提取调整混杂因素后的相关数据,采用Stata 12.0和R 3.2.2软件分别对数据进行常规Meta分析和剂量反应Meta分析。结果 共纳入15个研究,睡眠时间与2型糖尿病发病风险关系的常规Meta分析结果显示,与正常组比较,睡眠时间过短组2型糖尿病发病风险增加36%〔RR=1.36,95%CI(1.23,1.50),P<0.001〕,睡眠时间过长组2型糖尿病发病风险增加23%〔RR=1.23,95%CI(1.09,1.39),P=0.001〕。亚组分析结果显示,睡眠时间过短组在除欧洲地区亚组的其他亚组中均增加了2型糖尿病的发病风险(PZ<0.05);睡眠时间过长组在两种研究类型亚组、北美地区亚组及随访时间5~10年亚组中均增加了2型糖尿病的发病风险(PZ<0.05)。剂量反应Meta分析结果显示,睡眠时间与2型糖尿病发病风险呈非线性剂量反应关系,呈U型关系。与参照睡眠时间7.0 h/晚比较,睡眠时间5.5、6.0、6.5 h/晚2型糖尿病的发病风险为1.20〔95%CI(1.15,1.25)〕、1.10〔95%CI(1.08,1.13)〕、1.04〔95%CI(1.03,1.05)〕,睡眠时间7.5、8.0 h/晚2型糖尿病的发病风险为1.00〔95%CI(0.98,1.01)〕、1.02〔95%CI(0.99,1.06)〕,睡眠时间8.5、9.0、9.5 h/晚2型糖尿病的发病风险为1.07〔95%CI(1.01,1.14)〕、1.14〔95%CI(1.04,1.26)〕、1.23〔95%CI(1.07,1.40)〕。结论 睡眠时间过短和过长与2型糖尿病发病风险增加密切相关;睡眠时间<7.0 h/晚是2型糖尿病发病风险的危险因素,睡眠时间7.0~8.4 h/晚对2型糖尿病发病风险的影响不明显,而睡眠时间≥8.5 h/晚将导致2型糖尿病发病风险增加。因此,合理的睡眠时间有利于预防2型糖尿病。

Abstract: Objective To investigate the relationship between length of sleep and incidence risk of type 2 diabetes and to analyze the dose-response relationship between these factors.Methods PubMed,Web of Science,CNKI,and Wanfang Data Knowledge Service Platform were searched for prospective studies regarding the relationship between length of sleep and incidence risk of type 2 diabetes on September 22,2015.The quality of literature was evaluated,and relevant data were extracted after confounding factors were adjusted.Data were subjected to conventional meta-analysis and dose-response meta-analysis by using Stata 12.0 and R 3.2.2,respectively.Results Fifteen studies were included.Conventional meta-analysis revealed that the incidence risk of type 2 diabetes group with very short sleep was 36%〔RR=1.36,95%CI(1.23,1.50),P<0.001〕 higher than that of the normal group.The incidence risk of type 2 diabetes group with very long sleep was 23%〔RR=1.23,95%CI(1.09,1.39),P=0.001〕 higher than that of the normal group.Subgroup analysis showed that all of the subgroups with very short sleep,except the subgroup in Europe,exhibited an increased risk of type 2 diabetes(PZ<0.05).The group with very long sleep in two types of research subgroups,in subgroups in North America,and in 5-10 year’s follow up subgroups also experienced an increased risk of type 2 diabetes(PZ<0.05).Dose-response meta-analysis demonstrated that the length of sleep and incidence risk of type 2 diabetes presented a nonlinear relationship,that was,a U-shaped relationship.Compared with the reference level of 7.0 h/night,the incidence risk of type 2 diabetes of 5.5,6.0,and 6.5 h/night were 1.20〔95%CI(1.15,1.25)〕,1.10〔95%CI(1.08,1.13)〕,and 1.04〔95%CI(1.03,1.05)〕,respectively.By comparison,the incidence risk of type 2 diabetes of 7.5 and 8.0 h/night were 1.00〔95%CI(0.98,1.01)〕 and 1.02〔95%CI(0.99,1.66)〕,respectively.Furthermore,the incidence risk of type 2 diabetes of 8.5,9.0,and 9.5 h/night were 1.07〔95%CI(1.01,1.14)〕,1.14〔95%CI(1.04,1.26)〕,and 1.23〔95%CI(1.07,1.40)〕,respectively.Conclusion Extremely short or long sleep is closely associated with the increased risk of type 2 diabetes.Less than 7.0 h/night of sleep is a risk factor of type 2 diabetes.Approximately 7.0 to 8.4 h/night of sleep is unlikely a contributing factor of the risk of type 2 diabetes.More than 8.5 h/night of sleep possibly causes an increased risk of type 2 diabetes.Therefore,a reasonable length of sleep is beneficial for the prevention of type 2 diabetes.
