不能再让“熊孩子”晚睡了,会增加2型糖尿病风险
2017/08/17
可不能让“熊孩子”再晚睡了,近日,英国伦敦大学圣乔治学院的一项研究指出,儿童睡眠不足,会增加患2型糖尿病的风险。想要让孩子远离糖尿病,父母不仅仅要关心他们的饮食,还需要保证他们拥有充足的睡眠。


2型糖尿病,也被称为成人发病型糖尿病,多在35-40岁发病。除家族遗传因素外,比较常见的致病原因就是肥胖和高血糖。过去,儿童患2型糖尿病的情况非常少见,但是随着近些年“小胖纸”队伍在世界各地不断壮大,低龄人群中因运动量不够、过量摄入糖和高脂食品而罹患2型糖尿病的人数也在不断增加。

现在除了孩子的饮食习惯外,父母们还得关心一下孩子的睡眠。伦敦大学圣乔治学院最近的研究表明,睡眠不足也可能导致儿童罹患2型糖尿病。

这项研究从睡眠习惯开始着手调查,对4525名9至10岁英国儿童的身体测量数据、血液采样结果和问卷数据进行分析。参与调查的孩子的睡眠长度从8小时到12小时不等,平均每晚10.5小时。研究结果显示,睡眠较少的孩子不仅体脂含量高,患胰岛素抵抗综合征、极端超重或肥胖的风险也相应较高。这是因为夜间每增加一小时的睡眠都会对控制儿童的体重、降低血液中糖分积累及促进肌肉生长有帮助。该研究的领头人Christopher G Owen教授认为,这一发现暗示充足的睡眠可能成为应对2型糖尿病患病风险最简单可行的办法。研究在美国《儿科医学》杂志九月号上发表。

“儿童晚睡或是睡眠不规律,通常带来第二天的不按时进餐或漏餐,运动时间也随之减少。”美国科罗拉多大学Anschutz医学院和科罗拉多儿童医院儿童睡眠心理学家Stacey Simon具体解释了其中的关联性,其本人并未参与此项研究。

哥伦比亚大学精神病学研究者James Gangwisch指出,儿童体内掌管食欲的荷尔蒙的分泌水平会受到睡眠不足的影响,使儿童更容易感到饥饿,或是更想吃口味偏甜、偏咸的零食。这样就容易给肥胖、高血脂、糖尿病等疾病的来袭埋下伏笔。

2016年美国睡眠医学学会(AASM)曾发布关于儿童及成人睡眠时长的健康指南:6-12岁儿童,推荐睡眠时长9-12小时;13-18岁的青少年为8-10小时;成年人应不少于7小时。达到上述睡眠标准可以促进健康,包括改善注意力、行为、学习、记忆、情绪调节等。相反,睡眠不足不仅会导致高血压、肥胖、糖尿病等生理疾病,还会增加患上抑郁症的风险。充足的睡眠在任何情况下都是有益的,所以爸妈每日不厌其烦地督促你早睡早睡,这份苦心“熊孩子”们要多理解哦。

  • Sleep Duration and Risk of Type 2 Diabetes

    BACKGROUND: Associations between sleep duration and type 2 diabetes (T2D) risk markers in childhood have been little studied. We examined associations between self-reported sleep duration and T2D risk markers in children. METHODS: Cross-sectional study of 4525 multiethnic UK children aged 9 to 10 years. Sleep time was calculated from self-reported usual time of going to bed and getting up on a school day, validated in a subset using accelerometers. Fasting blood samples provided levels of serum lipids and insulin, plasma glucose, and HbA1c. Physical measures included height, weight, bioimpedance, and blood pressure. Multilevel linear regression models of anthropometric, T2D, and cardiovascular risk markers with sleep duration were adjusted for sex, age, month, ethnicity, socioeconomic position, observer (physical measures only), and random effect of school. RESULTS: On average, children slept 10.5 hours per night (95% range 8.0–12.0 hours). There were strong inverse graded relationships between sleep duration, adiposity, and diabetes risk markers. In adjusted models, a 1-hour-longer sleep duration was associated with 0.19 lower BMI (95% confidence interval [CI] 0.09 to 0.28), 0.03 kg/m5 lower fat mass index (95% CI 0.00 to 0.05 kg/m5), 2.9% lower homeostasis model assessment insulin resistance (95% CI 1.2% to 4.4%), and 0.24% lower fasting glucose (95% CI 0.03% to 0.44%); there was no association with HbA1c or cardiovascular risk. Associations with insulin and glucose remained after an additional adjustment for adiposity markers. CONCLUSIONS: The finding of an inverse association between sleep duration and T2D risk markers in childhood is novel. Intervention studies are needed to establish the causality of these associations, which could provide a simple strategy for early T2D prevention.
