探讨7~13岁儿童中合并极低出生体重(very low birth weight，VLBW)儿童的睡眠状况。

随机选取1997年至2003年在本院产科出生并完成2010年6月10日至25日身体测量、病史采集及《儿童睡眠状况调查量表》调查的78例合并极低出生体重儿童为研究对象，纳入VLBW组；随机选取同期在本院产科出生，并与VLBW组相同时间完成身体测量、病史采集及《儿童睡眠状况调查量表》的80例出生时为足月正常体重儿童，纳入对照组。两组儿童接受调查时，年龄为7~13岁(本研究遵循的程序符合湖北省荆州市第一人民医院人体试验委员会制定的伦理学标准，得到该委员会批准，分组征得受试对象监护人的知情同意，并与其签署临床研究知情同意书)。两组儿童无相关内科疾病史，目前健康状况良好，性别、年龄、接受调查时体重指数(body mass index，BMI)等比较，差异无显著意义(P>0.05)。

VLBW组睡眠时间较对照组短，非节假日就寝时间及起床时间均较对照组晚，但差异无显著意义(P>0.05)，而节假日就寝时间及起床时间较对照组早，差异亦无显著意义(P>0.05)。7~13岁儿童睡眠时间与胎龄、出生体重无相关性，VLBW组与对照组睡眠时间相同。

7~13岁儿童睡眠时间与胎龄、出生体重无相关性，但要获得最终结论，尚需多中心、大样本的前瞻性对照研究证实。

To investigate sleep quality and amount in children aged 7~13 years with very low birth weight(VLBW).

From 1997 to 2003, 78 very low birth weight infants who were accomplished physical measurements, medical records collection and questionnaire were included in the study(VLBW group, n=78). At the same time, 80 children with normal birth weight who also accomplished physical measurements, medical records collection and questionnaire were included in the study(normal group, n=80). The study protocol was approved by the Ethical Review Board of Investigation in the First People's Hospital of Jingzhou City. Informed consent was obtained from the parents of each participating child.All children were 7-13 years old in June 2010.

There was no significant difference in sleep quality and amount between VLBW group and normal group(P>0.05).

Children with very low birth weight had similar quality and amount of sleep to normal children.
