Memory complaints in the elderly: quality of life and daily living activities. A population based study.

OBJECTIVES

We investigate whether Subjective Memory Complaints (SMC) are associated with specific aspects of quality of life and activities of daily living.

METHODS

Cross-sectional descriptive epidemiological study (random sample of the non-institutionalized census population): 1637 subjects over 64 years. SMC were obtained through questions regarding memory complaints. Coop/Wonca questionnaire, Katz Index and Lawton Scale were also administrated.

RESULTS

A significant association between SMC with global quality of life and every dimension of quality of life is found (p<0.05). There is also a significant association with every item of Lawton Scale (p<0.001) and Katz Index (p<0.01). Variables associated with SMC identified by logistic regression are: difficulties in using telephone, in taking medication, in social activities and a low self perceived health.

DISCUSSION

Subjects with memory complaints are a heterogeneous group. Quality of life and activities of daily living are both associated with SMC.
