背景技术背景：鲜为人知的是，早期生活因素和调查反应之间的关系，在流行病学研究adultes.METHODS：儿童的20世纪50年代的队列是由12,150名儿童（男孩51.7%）出生在阿伯丁1950年至1956年，并在小学在1962年的城市。从同期记录中获得出生体重、胎龄、生长、行为和出生时及儿童期社会经济地位的信息。7岁、9岁和11岁时的认知测试分数也可从学校记录中获得。结果是回复邮寄问卷（2001-2003），以生存队列成员在middleage.RESULTS：11,282潜在邮寄科目，7,183（63.7%）返回问卷。应答率在女性中最高，那些父母在出生时结婚，出生时或童年时处于非手工社会阶层，兄弟姐妹较少，童年时比他们的年龄更高更重，Rutter B行为评分较低。在每个年龄段的儿童认知测试成绩强烈，积极相关的回答率的邮政问卷独立于其他早期生活因素单调整个范围内的测试成绩。结论：儿童认知水平与中年期问卷回答率之间的关联强度和一致性非常大，儿童认知水平与中年期问卷回答率之间的关联强度和一致性非常大。这表明，在整个正常范围内的儿童认知对构成问卷回答的一系列复杂的后期行为具有强大的影响。在流行病学研究中，儿童特征（特别是与认知有关的特征）与后来的健康之间的关联可能存在的反应偏差的程度可能比通常认识到的要大，至少在调查工具是邮寄问卷的情况下是这样。
BACKGROUND: Little is known about the relationship between early life factors and survey response in epidemiological studies of adults.METHODS: The Children of the 1950s cohort is composed of 12,150 children (boys 51.7%) born in Aberdeen 1950-56 and in primary schools in the city in 1962. Information on birth weight, gestational age, growth, behaviour and socio-economic position at birth and in childhood were obtained from contemporaneous records. Cognitive test scores at ages 7,9 and 11 years were also available from school records. The outcome was response to a postal questionnaire sent (2001-2003) to surviving cohort members in middle age.RESULTS: Of 11,282 potentially mailed subjects, 7,183 (63.7%) returned questionnaires. Response rates were highest among females, and those whose parents were married at birth, were in a non-manual social class at birth or in childhood, had fewer siblings, were taller and heavier in childhood for their age and had lower Rutter B behavioural scores. Childhood cognitive test scores at every age were strongly and positively related to the response rate to a postal questionnaire independently of other early life factors monotonically across the entire range of test scores. Those in the bottom fifth at age 11 had a response rate of 49% while those in the top fifth 75%.CONCLUSION: The strength and consistency of the association of childhood cognition with questionnaire response rate in middle age is surprisingly large. It suggests that childhood cognition across the entire normal range is a powerful influence on the complex set of later behaviours that comprise questionnaire response. The extent of possible response bias in epidemiological studies of the associations between childhood characteristics (particularly those related to cognition) and later health is probably larger than is generally realised, at least in situations where the survey instrument is a postal questionnaire.
