本世纪美国儿童的疾病模式已发生极大的变化。从前旧有的传染病大多数已得到控制。当今儿童面临的主要疾病是慢性病和致伤残病：哮喘死亡率增加一倍，白血病和脑肿瘤发病率上升，神经发育功能障碍较为流行，尿道下裂发病率增加一倍。环境化学毒物以及贫穷、种族歧视和医疗保健方面的不公平是促成这些儿科病的已知因素和可疑因素。儿童有接触１５０００种大量生产的合成化学物质的危险。这些化学物质广泛用于消费品中，广泛存在于环境中。其中半数以上未做毒性试验。儿童似乎对化学毒物特别敏感，这是因为他们不成比例的大量接触和他们固有的生物易感性造成的。为了预防美国儿童的环境性疾病，儿童环境卫生网呼吁拟订一个全国性的以儿童为中心的预防研究议事日程。这个议事日程必须认识到儿童对环境毒物的易感性。此议事日程必须包含：１）面向预防工作的新研究重点；２）以儿童为中心的健康危险评估和政策制定的新范例；以及３）对公众、卫生工作者和决策者进行环境病是由可预防性接触造成的并且是可避免的教育运动。为了稳定该议事日程，儿童环境卫生网呼吁长期稳定的投入和建立儿童环境卫生研究和预防中心全国网 The disease patterns of American children have changed dramatically in this century. Most of the old epidemics in the past have been brought under control. The main diseases that children are facing today are chronic and traumatic disabilities: double the death rate from asthma, increased incidence of leukemia and brain tumors, prevalence of neurodevelopmental dysfunction, and double the incidence of hypospadias. Environmental chemical poisons and inequalities in poverty, racial discrimination and health care are both known and suspicious factors that contribute to these pediatric diseases. Children are at risk of exposure to 15,000 mass-produced synthetic chemicals. These chemicals are widely used in consumer products and widely found in the environment. More than half of them did not make toxicity test. Children appear to be particularly sensitive to chemical poisoning because of their disproportionate exposure to large quantities and their inherent biological susceptibility. To prevent environmental diseases in U.S. children, Kidney Network called for a nationwide child-focused prevention research agenda. This agenda must recognize the child’s susceptibility to environmental toxins. This agenda must include: 1) new research priorities for preventive work; 2) a new paradigm for child-centered health risk assessment and policy development; and 3) environmental disease for the public, health workers and policy makers It is a preventable educational campaign that is caused by preventable sexual contact. In order to stabilize the agenda, CHN calls for long-term and steady investment in and establishment of a National Network for Children’s Research and Prevention Center for Environmental Health
