The National Child Development Study (NCDS) is a continuing, multi-disciplinary longitudinal study which follows the lives of about 17,000 people born in Great Britain in a certain week in 1958. ==History== The NCDS has been conducted in nine different sweeps so far. After the initial survey in 1958, there have been attempts to trace all members of this birth generational cohort in 1965, 1969, 1974, 1981, 1991, 1999–2000, 2004, 2008 and 2014 to get information concerning their physical, educational and social development.〔(United Kingdom Data Service, NCDS webpages ), retrieved June 6, 2015〕 During the period 2002-2004, genetic information on participants was also obtained to examine the genetic effects on common traits and diseases.〔(2002-2004 Biomedical follow-up, retrieved January 6th, 2011 )〕 The origins of the NCDS can be found in the (Perinatal Mortality Survey ) (PMS) which was then sponsored by the (National Birthday Trust Fund ) and set up to collect information about the social and obstetric factors associated with stillbirth and death in early infancy.〔(UKDS, NCDS catalogue record entry ), retrieved September 21, 2009〕 Examples of other topics which have since been included are medical care, health, home environment, educational progress, parental involvement, family relationships, economic activity, income, training and housing.〔UKDS, NCDS webpages〕 Following the initial birth survey, the four subsequent sweeps were carried out by the National Children's Bureau. In 1985, the NCDS was moved to the Social Statistics Research Unit (SSRU), which is now known as the (Centre for Longitudinal Studies ) (CLS).〔UKDS, NCDS catalogue record entry〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「National Child Development Study」の詳細全文を読む スポンサード リンク
