Aging in Manitoba (AIM) Longitudinal Study

Study description

The Aging in Manitoba (AIM) Longitudinal Study is the longest continuous study of Aging in Canada. It has involved almost 9000 older Manitobans between 1971 and 2001 in personal interviews. The interview collects information on socio-demographic, social psychological, physical and mental health status and functioning, economics, leisure activities, care and support networks and consumption of services (See Variable Matrix).

The AIM Longitudinal Studies began in 1971 with a random sample (N=4803) stratified by age and gender using a small area probability sampling frame of both community and institutional dwelling Manitobans aged 65 and over. A second cross-section of seniors was surveyed in 1976 (N=1302) and a third cross-sectional sample (N=2873) was interviewed in 1983. Also in 1983/84 the panel of survivors from 1971 and 1976 (N=2399) was re-interviewed and again in 1990 with the survivors from 1983 (N=3218). In 1996, the panel included 1,868 older Manitobans and the 2001 panel produced re-interviews with 1012 survivors (Figure 1). Study description (PDF)

As of May, 2009 the interview data for all waves of the Aging in Manitoba Longitudinal Study are housed at the Centre on Aging University of Manitoba. Access to these data for research purposes is through the Centre on Aging (See Applying for Access).

The interview data have been linked to the full spectrum of health services utilization data from the administrative data base of the Manitoba insured services and the services delivered directly by Manitoba Health for the period 1970-2004 including death certificates for all known decedents. The health services utilization data is housed at the Manitoba Centre for Health Policy (MCHP), University of Manitoba and access to this data must be obtained through MCHP.
