Pediatrics:塑料化学品或增儿童患肥胖和糖尿病风险

2013-09-03 Alexa 译 医学论坛网

美国的研究人员近期开展了两项研究:邻苯二甲酸(一种化学品,平日用于制造香水,也可用于软化塑料的化学品)和双酚A(BPA,在工业上双酚A被用来合成聚碳酸酯和环氧树脂等材料,60年代以来就被用于制造塑料瓶、幼儿用的吸口杯、食品和饮料罐内侧涂层)与儿童胰岛素抵抗和肥胖之间的关系。

美国的研究人员近期开展了两项研究:邻苯二甲酸(一种化学品,平日用于制造香水,也可用于软化塑料的化学品)和双酚A(BPA,在工业上双酚A被用来合成聚碳酸酯和环氧树脂等材料,60年代以来就被用于制造塑料瓶、幼儿用的吸口杯、食品和饮料罐内侧涂层)与儿童胰岛素抵抗和肥胖之间的关系。

其中一项研究围绕邻苯二甲酸与儿童胰岛素抵抗增加的关系,而另一项则是关于双酚A与儿童体质指数(BMI)和腰围增长之间的关系。两项研究分析结果表明,塑料食品包装和容器中使用的化学品可能导致儿童的糖尿病和肥胖。相关研究在线发表在8月19日的《儿科》杂志上。【研究文献下载】

越来越多的人开始关注环境中化学物质对儿童健康的影响,尤其是现下流行的儿童肥胖。邻苯二甲酸的研究者,纽约大学医学院儿科学和环境医学的副教授Leonardo Trasande博士说:“我们的研究就是关注这些。”

Trasande的回顾研究了有胰岛素抵抗和尿中有邻苯二甲酸的766名12~19岁儿童。先前的研究已发现,接触邻苯二甲酸酯与动物和成年人的胰岛素抵抗密切相关。邻苯二甲酸是用来软化塑料和乙烯制品的化学品,已经被怀疑干扰人体正常内分泌功能,相关的厂家也已经停产了邻苯二甲酸制造的牙环和奶嘴等婴儿产品。

尽管新的研究发现了塑料化学物与儿童胰岛抵抗和肥胖之间存在关联,但并不能证明其中存在因果关系。

耶鲁大学医学院妇产科及生殖科学主任HughTaylor博士表示,这些研究结果显示出,儿童面对环境化学物时是十分脆弱的。年龄越小,越多的技能处于发育阶段,对于这些外界侵袭则越敏感易损。

然而,Taylor博士同时也强调,与有害的化学物质相比,包裹于塑制包装中的食物本身对于糖尿病及肥胖有着同等的促进作用,甚至影响更大。孩子们所摄取的食物类型可能才是关键。更健康的天然食物始终是更好的选择。这不仅仅可以消除塑料塑料化学物的影响,还能带来诸多健康效益。

Taylor博士还建议,不用使用微博加热塑制品,塑料容器采用手洗,对于由腐蚀或其他损坏的塑料容器应丢弃不再使用。

Kidney. Int:宁光等发现塑料用品易引发白蛋白尿

近期,上海交通大学医学院附属瑞金医院内分泌代谢科宁光教授等开展的一项研究表明,长期接触双酚A 可致低水平白蛋白尿(尿白蛋白肌酐比值为9.71~29.9 mg/g)风险增加。相关论文发表在Kidney International杂志上。 双酚A 是一种广泛用于塑料制品行业的工业化学物质,常被用来生产聚碳酸酯塑料和环氧树脂,水瓶和很多食品容器中均含有双酚A。 该研究纳入上海3455 例年龄≥ 40
