项目摘要

DESCRIPTION (provided by applicant): With the rapid advances in communication technologies, children are increasingly exposed to the radiofrequency (RF) fields starting from a very early age. As cellular telephones are a new, but increasingly common source of a relatively high RF fields, concerns are increasing that this technology could have negative health effects. Investigation need to be initiated immediately while there are still some populations with no or low exposure. In line with the NIEHS's mission to promote the public's right to a healthy environment, the aim of this proposed research is to understand whether exposure to cellular telephones in childhood can have effects on the central nervous system and whether children might be particularly at risk. The Danish National Birth Cohort (DNBC) represents a unique resource, which will allow us to efficiently evaluate whether exposures [in children] lead to behavioral and developmental effects. The cohort consists of over 100,000 Danish children, who were born between 1996 and 2002. Detailed information on lifestyle factors, dietary habits and environmental exposures has been collected. When these children reached the age of seven, we began to ask about current use of cell phones by children. Our results among 10% of the children suggest that cell phone exposure might be related to behavioral and developmental problems. These findings need to be replicated for the rest of the cohort, [and to evaluate if our findings are limited to "early users", who might be different from the rest of the population. Also, several additional potential confounders have been suggested, and we plan re-analysis adjusting for these factors.] We also propose to investigate other central-nervous system-related outcomes such as seizures, autism, migraines, and sleep disturbances. The proposed novel project is the first large scale study to examine health effects of cell phone use early in life. Given that there are over two billion subscribers worldwide and that children are beginning to use cell phones at earlier ages, studies of children have been determined to be of the highest priority by both national and international organizations, including the World Health Organization and National Academy of Sciences. Children may be at greater risk because: 1) their exposure to the RF might be higher due to differences in the anatomy, tissue conductivity and other factors; 2) they might be more susceptible due to the developing organ and tissue systems, particularly of the nervous system; and 3) children born in the last decade are part of a unique population that will have lifelong cell phone exposure. [Our preliminary results have results have received a widespread scientific and media attention. Several issues have been raised post publication.] Here we propose to address these issues and thus to significantly advance our knowledge on health effects of RF field exposure in a potentially vulnerable population and contribute to the risk assessment and policy development of this ubiquitous and rapidly increasing exposure. We believe such a study is urgently needed and at present it can only be done using data sources outside the U.S. PUBLIC HEALTH RELEVANCE: To date potential health effects of cell phone use [in children] have not been adequately examined. As this exposure is extremely prevalent, even very small effects of cell phone exposure could have a large public health impact. [We have reported an important result which needs replication: further information will have immediate policy implications.] If our findings are confirmed reducing exposure in this very vulnerable population is easily achievable.

描述（由申请人提供）：随着通信技术的快速发展，儿童从很小的时候就开始越来越多地接触射频（RF）场。由于蜂窝电话是一种新的、但越来越常见的相对较高射频场来源，人们越来越担心这项技术可能会对健康产生负面影响。在仍有部分人群没有或低暴露的情况下，需要立即启动调查。根据 NIEHS 促进公众享有健康环境的权利的使命，这项拟议研究的目的是了解儿童时期接触手机是否会对中枢神经系统产生影响，以及儿童是否可能面临特别高的风险。丹麦国家出生队列 (DNBC) 代表了一种独特的资源，它将使我们能够有效评估接触[儿童]是否会导致行为和发育影响。该队列由超过 100,000 名 1996 年至 2002 年间出生的丹麦儿童组成。已经收集了有关生活方式因素、饮食习惯和环境暴露的详细信息。当这些孩子到了七岁的时候，我们开始询问孩子们目前使用手机的情况。我们对 10% 儿童的研究结果表明，接触手机可能与行为和发育问题有关。这些发现需要在其他人群中复制，[并评估我们的发现是否仅限于“早期用户”，他们可能与其他人群不同。此外，还提出了一些其他潜在的混杂因素，我们计划根据这些因素进行重新分析调整。]我们还建议调查其他中枢神经系统相关的结果，例如癫痫、自闭症、偏头痛和睡眠障碍。拟议的新项目是第一个大规模研究，旨在检查生命早期使用手机对健康的影响。鉴于全球有超过 20 亿用户，并且儿童开始使用手机的年龄较早，世界卫生组织和美国国家科学院等国家和国际组织已将儿童研究确定为最高优先事项。科学。儿童可能面临更大的风险，因为：1）由于解剖结构、组织电导率和其他因素的差异，他们接触射频的风险可能更高； 2) 由于器官和组织系统正在发育，特别是神经系统，他们可能更容易受到影响； 3) 过去十年出生的儿童是终生接触手机的独特人群的一部分。 [我们的初步结果已受到科学界和媒体的广泛关注。出版后提出了几个问题。] 在这里，我们建议解决这些问题，从而显着提高我们对射频场暴露对潜在弱势群体的健康影响的认识，并为这种普遍存在且迅速增加的风险评估和政策制定做出贡献接触。我们认为这样的研究是迫切需要的，目前只能使用美国以外的数据源来完成。公共健康相关性：迄今为止，[儿童]使用手机的潜在健康影响尚未得到充分研究。由于这种接触非常普遍，即使接触手机的影响非常小，也可能对公共健康产生巨大影响。 [我们报告了一个需要复制的重要结果：进一步的信息将产生直接的政策影响。]如果我们的研究结果得到证实，减少这一非常脆弱人群的暴露是很容易实现的。
