The Swedish Adoption/Twin Study of Aging (SATSA) is a longitudinal program of research in gerontological genetics which is currently in its fifth year. The base population is comprised of 351 pairs of twins reared apart and 407 matched control pairs of twins reared together who responded to a questionnaire (Q1) in 1984. Two additional stages of SATSA have recently been completed: a longitudinal follow-up questionnaire mailed out in 1987 (Q2) and extensive in-person testing (IPT1) which included a health examination and cognitive battery. A second wave of IPT was started in January 1989. A summary of some of the major findings from Q1 and a description of IPT1 are reported.
瑞典收养/衰老双胞胎研究（SATSA）是老年遗传学领域的一项纵向研究项目，目前已进入第五年。基础人群包括1984年对一份问卷（Q1）做出回应的351对分开抚养的双胞胎和407对匹配的共同抚养的双胞胎对照。SATSA最近又完成了两个阶段：1987年寄出的纵向随访问卷（Q2）以及包括健康检查和认知测试的广泛的现场测试（IPT1）。1989年1月开始了第二轮IPT。报告了Q1的一些主要发现总结以及IPT1的描述。
