Diabetes Care:高能量饮食或与儿童2型糖尿病风险相关

2014-01-23 佚名 不详

能量摄入、能量密度和营养素摄入量与成人2型糖尿病风险有关,但是它们对当前出现的儿童2型糖尿病风险的影响尚不清楚。针对这个问题,来自伦敦大学人口健康科学和教育学院的Donin博士等以多民族儿童为研究对象,对这些影响因素的联系进行了研究,发现总能量摄入量与胰岛素抵抗呈正相关。研究结果在线发表于2103年8月12日的Diabetes Care杂志上。 这是一项横断面研究,研究对象为2017名儿童,包括

能量摄入、能量密度和营养素摄入量与成人2型糖尿病风险有关,但是它们对当前出现的儿童2型糖尿病风险的影响尚不清楚。针对这个问题,来自伦敦大学人口健康科学和教育学院的Donin博士等以多民族儿童为研究对象,对这些影响因素的联系进行了研究,发现总能量摄入量与胰岛素抵抗呈正相关。研究结果在线发表于2103年8月12日的Diabetes Care杂志上。

这是一项横断面研究,研究对象为2017名儿童,包括欧洲白人、南亚人和非洲黑人(加勒比土著人),年龄9-10岁。通过详细的24h膳食回忆,身体组成成分测量数据收集,采集空腹血样以测定血糖浓度、HbA1c和血清胰岛素含量,并计算 HOMA胰岛素抵抗指数。

结果显示,能量摄入与胰岛素抵抗呈正相关。去除176名能量摄入不合理的参与者后(因为他们的能量摄入不代表习惯摄入量),能量摄入与胰岛素抵抗的相关性更为明显,并且与血糖和脂肪量指数相关。此外,能量密度也与胰岛素抵抗和脂肪量指数呈正相关。在相互校正的分析后,胰岛素抵抗与能量摄入仍具相关性,而与能量密度却无显著性相关。个人营养素摄入量与2型糖尿病风险标志物没有相关性。


胰岛素抵抗指数

研究发现,总能量摄入量较高与胰岛素抵抗程度升高具有明显的相关性,这可能有助于解释当前出现的儿童2型糖尿病风险。为了确定减少能量摄入,是否能对胰岛素抵抗和血糖水平产生持久、有利的改变,仍需要相关的研究。
