A prospective geographically based series of population studies has been designed to start in pregnancy and to follow the cohort of births until the age of 7 years. Various centres within Europe are participating in this survey, although there is still time for others to join. The strength of the survey relies on the fact that different correlations in different countries may be useful in ascertaining causal relationships and the major thrust of the research is to assess the impact of psychosocial factors on child health and development.
一项基于地理位置的前瞻性系列人群研究已设计完成，研究将从孕期开始，追踪出生队列直至7岁。欧洲的各个中心都在参与这项调查，不过仍有时间让其他机构加入。该调查的优势在于，不同国家的不同相关性可能有助于确定因果关系，而研究的主要目的是评估心理社会因素对儿童健康和发育的影响。
