The Center is currently involved in projects using the data below.
The Nihon University Longitudinal Study on Aging (NUJLSOA)
The NUJLSOA is a longitudinal Survey of a nationally representative sample of the Japanese population age 65 and older begun in 1999. Interviews were conducted in November 1999 with additional respondents added in March 2000 when a follow-up of nonrespondents was completed. This resulted in a sample of 4,997 and a response rate of 75%. The final sample of 4,997 respondents ranged in age from 65 to 104 with a mean age of 77 years, and was nearly 41% male. The surveys included questions on functioning, chronic conditions and impairments, health behaviors, and social and demographic characteristics. The NUJLSOA was designed to be comparable to the U.S. Longitudinal Study on Aging II (LSOAII). Data from the first wave can be obtained from Nihon University through Yasuhiko Saito (email@example.com) and through the USC/UCLA Center. Four total waves have been collected. The last two will be made available in the future.
The USC Longitudinal Study of the Generations (LSOG)
The USC Longitudinal Study of the Generations began in 1971 as a survey of intergenerational relations within 300 three-generation California families: the grandparents (then in their 60s), middle-aged parents (then in their early 40s), and grandchildren (then aged 16-26). The purpose of the study is to investigate similarities and differences in inter-generational familial relationships as the decades pass and with the aging of each generation. The study also explores how these changes impact the well-being of individuals within the family. The study now includes fourth and even fifth generations of the same families. Information was collected in 1985, 1988, 1991, 1994, 1997, and 2001. The research is funded by the National Institute on Aging. The Principal Investigator is Merrill Silverstein.
The MacArthur Research Network on Successful Aging Community Study
The MacArthur Research Network on Successful Aging Community Study is a longitudinal, three-site cohort study of high-functioning Americans aged 70-79 in 1988. The MacArthur Study followed these persons over 7 years, re-interviewing them in 1991 and 1995. In addition to basic social and demographic variables, biological sample of blood and urine have been analyzed, with additional sample stored for later assays. Passive follow-up of mortality using Medicare records has subsequently taken place. More information can be obtained by contacting Teresa Seeman (Tseeman@mednet.ucla.edu).
