Sex difference in depression and quality of life in elderly people.

Two hundred and two elderly people who have been visiting a Day Service Center were examined by a Japanese version of the self-rating depression scale by Zung (SDS) and the quality of life rating scale to suit Japanese conditions (QOL scale). The QOL scale measures four aspects: physical functioning, emotional adjustment, interpersonal relationship and attitudes toward life. Significant correlations were seen between the scores of three aspects and the total score except for the score of interpersonal relationship. Although no significant difference was found between the sexes in scores of the SDS, all the scores of aspects and the total score of the QOL scale of the male subjects were significantly higher than those of the female subjects.
