Design:
Prospective cohort study.
Setting:
Family practices in the Netherlands (Maastricht Aging Study); 1993 to 2001.
Population:
485 people aged 60 or over. Exclusion criteria: clinical diagnosis of depression or dementia; cognitive function impairment due to a medical condition.
Prognostic factors:
Sensorimotor speed, memory, and executive functioning, (compound scores derived from the relevant sections of the Stroop Colour-Word test, Concept Shifting Task, and Visual Verbal Learning Test). Analyses were adjusted for age, gender, educational level, length of follow up, and cognitive function at baseline.
Outcomes:
Functional status (physical and mental components of the SF-36 questionnaire).
Follow up period:
Three and six years.
At baseline, higher cognitive function was significantly associated with higher functional status. However, there was no correlation between cognitive function at baseline, and decline in functional status at three years (see http://www.ebmentalhealth.com/supplemental for table) or six years (data not shown).
Sensorimotor speed, memory, and executive functioning were not
