IJCP:二战期间遭受严重饥饿妇女患乳腺癌风险高

2012-10-08 网络 网络

  据《国际临床实践杂志》(IJCP)十月份发表的一篇研究报道称,二战期间,犹太妇女中遭受严重饥饿的妇女与那些只是遭受轻微饥饿的妇女相比,前者出现乳腺癌的风险是后者的5倍多。该研究还发现,在那期间(二战),年龄到7岁的女性要比当时14岁及以上的女性后来进展出现乳腺癌的风险高出3倍多。   2005-2010年间被诊断为乳腺癌的65例妇女患者,同时还有200例没有乳腺癌的妇女作为对照。所有的妇女均

  据《国际临床实践杂志》(IJCP)十月份发表的一篇研究报道称,二战期间,犹太妇女中遭受严重饥饿的妇女与那些只是遭受轻微饥饿的妇女相比,前者出现乳腺癌的风险是后者的5倍多。该研究还发现,在那期间(二战),年龄到7岁的女性要比当时14岁及以上的女性后来进展出现乳腺癌的风险高出3倍多。

  2005-2010年间被诊断为乳腺癌的65例妇女患者,同时还有200例没有乳腺癌的妇女作为对照。所有的妇女均生活在以色列。乳腺癌病例从五个医学中心收集而来,对照组妇女为二战中幸存下来的各种组织的犹太人成员。

  来自以色列海法(Haifa)大学公共卫生学院的Neomi Vin-Raviv博士解释说:“所有参与我们研究的妇女都曾在**的控制下至少有六个月。我们渴望看到在这段时间限制卡路里会对乳腺癌的形、进展带来什么样的影响,以及在幼年乳腺发育之前限制卡路里有来怎样的潜在风险。我们相信,我们的研究结果将会引起临床医生治疗相关任何情况下妇女时的兴趣,比如战争和饥荒,此时食物匮乏,饥饿严重。”

  该项研究的关键结果包括:参与研究时乳腺癌妇女的平均年龄为76.2岁,对照组妇女的平均年龄为78.3岁。乳腺癌妇女多易出现肥胖,对照组妇女更容易出现体重超重。在吸烟状况、酒精摄入、当前运动量以及生育和妇科特点方面均无显着差别。

  与对照组(27%)相比,二战时7岁或者更小的妇女出现乳腺癌的几率要高得多,为49.2%。12%的乳腺癌妇女出生于二战时,对照组这一比例为7.5%。63%的乳腺癌妇女生活在**的直接统治下,对照组为83.5%,其余居住在与**政权有合作的“独立国家”。61.5%的乳腺癌妇女曾遭受过严重的饥饿,没有乳腺癌的对照组妇女中遭受严重饥饿的为37%。遭受中等程度饥饿的比例分别为17%和38%,轻微饥饿的比例分别为21.5%和25%。与遭受轻微饥饿的妇女相比,遭受严重饥饿的妇女进展称乳腺癌的几率要高出5倍多。年龄在7岁及以下的进展为乳腺癌的几率增加2.8倍。

  Dr Vin-Raviv说:“限制卡路里摄入与癌症之间是一个复杂(的关系)。虽然在我们的论文中对几种理论做了讨论,但未来仍需要进一步的生物机制研究。从我们的研究结果来看,目前可以肯定的是在犹太幸存者当中,严重饥饿和乳腺癌之间存在明显的关联,同时在当时大战期间年龄在7岁或者更小的女性是最易受影响的组。这些研究发现不仅仅与二战幸存者相关,对于一些当前正处于卡路里摄入受限制状态的其他社区(也是适用的)。”
