研究目的-这项分析的目的是比较响应率的邀请参加筛选在一个多中心，多国研究在European.Design -这是一个人口调查设置-三十四个中心在16个欧洲countries.Subjects -男性和女性年龄在50岁及以上被招募从人口为基础的抽样框架参加骨质疏松症的患病率调查。受试者被邀请邮寄参加放射性检查和面试，和无应答者进行了后续重复mailing.Results -有一个很大的变化中心之间的响应率：平均值为49%，范围5- 83%。对已知死亡或搬家的人进行调整并不影响总体排名。各中心对每封邮件的答复率也各不相同：第一封邮件的答复率为45%（范围5-83%），第二封邮件的答复率为10%（范围0-23%）。答复率因年龄和性别而异，妇女的答复率高于男子。女性的发病率随着年龄的增长而逐渐下降，但男性的发病率在65岁之前一直上升。答复率因区域而异。这些是最高的国家从北方欧洲和南欧国家最低，但有很大的差异，无论是在区域内和国家内Conclusions -多中心，在欧洲的多国研究可能会越来越受欢迎。在本研究中，尽管采用了标准化方法，但国家内和国家间各中心之间的缓解率差异很大。试图在调查设计中实现跨国标准化，对产生一致的响应效果有限。
Study objective - This analysis aimed to compare the response rates of those invited to attend for screening in a multicentre, multinational study within Europe.Design - This was a population survey.Setting - Thirty four centres in 16 European countries.Subjects - Men and women aged 50 years and over were recruited from population based sampling frames to participate in a prevalence survey of osteoporosis. Subjects were invited by post to attend for radiological screening and interview, and non-responders were followed up by repeat mailing.Results - There was a substantial variation between centres in response rates: the mean was 49% and the range 5-83%. Adjusting for those known to have died or moved house did not affect the overall ranking. The response rates to each mailing also varied between centres: first mailing 45% (range 5-83%) and second mailing mean 10% (range 0-23%). The response rates varied in relation to age and sex and were higher in women than men. Rates fell gradually with age in women but rose in men until the age of 65 years. Response rates varied regionally. These were highest in countries from northern Europe and lowest in southern European countries, but there was wide variation both within regions and within countries.Conclusions - Multicentre, multinational studies within Europe will probably become increasingly popular. In this study, despite a standardised approach, the range in response rates between centres both within and between countries was substantial. Attempts at cross national standardisation in survey design can have only a Limited effect on yielding uniformity in response.
