Collected Dataset / ALSA_Wave1

The primary sample of the older old adults (70 and older) was randomly drawn from the database of the South Australian Electoral Roll. Persons in the older age groups as well as males were deliberately over sampled to compensate for the higher mortality that could be expected over the study period. In addition, spouses of primary respondents (aged 65 and over) and other household members aged 70 and over were asked to participate.

A comprehensive personal interview and assessment of neuropsychological and physiological functions was undertaken at each person's home, supplemented by self-completed questionnaires, biochemistry, and additional clinical studies of physical function.
