[Evaluation of mental and communication functions in mapuche and non mapuche elderly subjects in rural communities in Southern Chile].
BACKGROUND
The main predictors of functional impairment in the elderly are alterations in mental or communication functions.


OBJECTIVE
To study mental and communication functions in rural elderly subjects of Mapuche and non Mapuche origin.


METHODS
Elderly subjects coming from a rural Mapuche community and a non Mapuche community were studied. Subjects were interviewed at their homes. The communication and mental function assessments of the Functional Autonomy Measurement System were applied.


RESULTS
Fifty one Mapuche and 49 non Mapuche subjects with a mean age of 71 +/- 7 and 74 +/- 8 years respectively, were studied. Fifty four percent were female and 31% were illiterate. Twenty six percent had impairment in mental functions. The item with the highest difficulty was memory. The visual function was the most severely impaired among communication items. Mapuche elderly subjects had significantly higher degrees of impairment in mental and communication functions.


CONCLUSIONS
There is a higher degree of mental and communication impairment among rural Mapuche elderly subjects than in their non Mapuche counterparts.
