研究发现儿童肥胖 “35-40%” 源至父母

2017-02-22 zphb141223 来宝网

一项新的研究发现大约 35-40% 儿童身体质量指数(BMI)—衡量人体胖瘦程度以及是否健康的标准—来源于父母的遗传。肥胖儿童的比例已上升至 55-60%,他们中有一半的肥胖原因是由基因和家庭环境决定的。这项由苏塞克斯大学领导的研究使用了 10 万名儿童及其父母的身高和体重数据,遍及全球六个国家:英国、美国、中国、印度尼西亚、西班牙和墨西哥。 研究人员发现 BMI 的代际传递对于每个家长大约为 0

一项新的研究发现大约 35-40% 儿童身体质量指数(BMI)—衡量人体胖瘦程度以及是否健康的标准—来源于父母的遗传。

肥胖儿童的比例已上升至 55-60%,他们中有一半的肥胖原因是由基因和家庭环境决定的。

这项由苏塞克斯大学领导的研究使用了 10 万名儿童及其父母的身高和体重数据,遍及全球六个国家:英国、美国、中国、印度尼西亚、西班牙和墨西哥。 研究人员发现 BMI 的代际传递对于每个家长大约为 0.2—即每个孩子的 BMI 平均 20% 归因于母亲,20% 归因于父亲。

萨塞克斯大学首席教授 Peter Dolton 说,这个实验的结果在所有国家都是非常一致的,不论它们的经济发展状态,工业化程度或者经济类型如何。我们的证据来自世界各地且多样化的营养和肥胖数据,从最肥胖的人口之一美国到世界上最瘦的两个国家—中国和印度尼西亚。

这给发达国家和发展中国家如何跨代传播肥胖提供了重要的视角。“我们发现不同国家代际传递的过程都是相同的,” 该研究结果发表在杂志《经济与人类生物学》。

研究还显示父母的 BMI 对孩子 BMI 的影响取决于孩子的 BMI。在所有研究人群中,他们发现 “父母效应” 的影响对于越瘦的孩子越低,而越胖的孩子则越高。对于最瘦的孩子,他们的 BMI10% 归因于母亲,10% 归因于父亲。对于最胖的孩子,这种代际传递则达到 30%。

Dolton 教授谈到,这表明肥胖父母养育的小孩更可能肥胖—因为父母的影响更大。“这些发现对世界儿童的健康具有深远影响,他们让我们重新思考肥胖是家庭和遗传共同影响的结果,而不是由我们个人决定的。”
