Use of drugs by non-institutionalized urban Finns born in 1904-1923 and the association of drug use with mood and self-rated health.

The purpose of this study was to examine the use of drugs by elderly people and to investigate its associations with various other factors. Random sampling was used to select 800 interviewees born in 1904-13 and a further 800 born in 1914-23. The average number of prescribed drugs per person was 2.2. Women used a greater number of prescribed drugs than did men; and this difference increased with age. The use of vitamins and trace elements seemed to decline with increasing age. Among women a significant association between the use of prescribed drugs and depressive symptoms was found. Women in the older age group used prescribed drugs more often than women in the younger age group. One fifth of the subjects had a greater number of drugs in simultaneous use than is generally recommended. It seems that, especially among elderly women, depression often remains undiagnosed and treatments are chiefly provided for the associated symptoms.
