CARDIA_Cohort. Homo sapiens

CARDIA is a study examining the etiology and natural history of cardiovascular disease beginning in young adulthood. In 1985-1986, a cohort of 5115 healthy black and white men and women aged 18-30 years were selected to have approximately the same number of people in subgroups of age (18-24 and 25-30), sex, race, and education (high school or less and more than high school) within each of four US Field Centers. These same participants were asked to participate in follow-up examinations during 1987-1988 (Year 2), 1990-1991 (Year 5), 1992-1993 (Year 7), 1995-1996 (Year 10), 2000-2001 (Year 15), 2005-2006 (Year 20), and 2010-2011 (Year 25); the proportions of the surviving cohort that have returned for the seven follow-up examinations were 90%, 86%, 81%, 79%, 74%, 72%, and 72%, respectively. In addition to the follow-up examinations, participants are contacted regularly for the ascertainment of information on out-patient procedures and hospitalizations experienced...

CARDIA研究旨在探究始于青年成年阶段的心血管疾病病因学与自然病程。1985至1986年间，研究于美国4个现场中心内，按照年龄（18-24岁、25-30岁）、性别、种族与受教育程度（高中及以下、高中以上）进行分层，招募了5115名年龄在18-30岁的健康黑人和白人男女作为队列对象，各亚组人数大致相当。上述队列参与者先后受邀参与1987-1988年（第2年）、1990-1991年（第5年）、1992-1993年（第7年）、1995-1996年（第10年）、2000-2001年（第15年）、2005-2006年（第20年）以及2010-2011年（第25年）的随访检查；存活队列参与这7次随访检查的比例分别为90%、86%、81%、79%、74%、72%与72%。除随访检查外，研究团队还会定期联系参与者，以核实其门诊诊疗操作与住院治疗的相关信息（更多详情请参见dbGaP研究页面）。
