LSOA II Linked Mortality File
NCHS has conducted a mortality linkage of the Second Longitudinal Study of Aging (LSOA II) to death certificate data found in the National Death Index (NDI). The LSOA II is a prospective survey of 9,447 civilian non-institutionalized persons 70 years of age and over at the time of their baseline interview. This baseline interview, also known as the Second Supplement on Aging (SOA II), was conducted in 1994-1996. The LSOA II followed this cohort of older persons through two follow-up interviews, in 1997-1998 and 1999-2000. Linkage of the LSOA II survey participants with the NDI provides the opportunity to conduct studies designed to investigate the association of a variety of health factors with mortality. NCHS has created two versions of the LSOA II Linked Mortality File: a public-use file that includes a limited set of mortality variables and a restricted-use file that includes more detailed mortality information.
The LSOA II Linked Mortality File contains information based upon the results from a probabilistic match between the LSOA II and NDI death certificate records, as well as previously identified deaths collected during the Second Longitudinal Study of Aging. The LSOA II Linked Mortality File provides mortality follow-up data from the date of LSOA II survey participation (1994-2000) through December 31, 2002. All LSOA II participants aged 70 years of age and over are included on the Linked Mortality File.
