美国《科学》杂志报道,绝大多数人都希望自己是高个子,但个子高也有不利的一面。根据刊登在《柳叶刀—肿瘤学》(The Lancet Oncology)杂志上的研究发现,高个子的女性更容易患上癌症。研究发现不同经济阶层的女性患所有类型癌症的风险都与个子高存在一定联系。
9年来,科学家对英国一项长期健康研究的130万名参与者患17种癌症的风险进行了分析,其中包括乳腺癌和白血病。根据他们的分析发现,身高每提高10厘米,癌症风险提高16%。这一风险与此前10项有关欧洲、亚洲、澳大利亚和北美居民癌症与身高关系的研究得出的结果类似。自1900年以来,欧洲成年人的平均身高每10年增加1厘米,癌症发病率增加了10%至15%。更高的身高为何导致癌症风险提高仍是一个未知数。一种可能性是,促使儿童长高的激素同样刺激癌细胞生长。(生物谷 Bioon.com)

Height and cancer incidence in the Million Women Study: prospective cohort, and meta-analysis of prospective studies of height and total cancer risk
Jane Green
Epidemiological studies have shown that taller people are at increased risk of cancer, but it is unclear if height-associated risks vary by cancer site, or by other factors such as smoking and socioeconomic status. Our aim was to investigate these associations in a large UK prospective cohort with sufficient information on incident cancer to allow direct comparison of height-associated risk across cancer sites and in relation to major potential confounding and modifying factors. Cancer incidence increases with increasing adult height for most cancer sites. The relation between height and total cancer RR is similar in different populations.
