Abstract
The aim was to examine the relationship between mental health and use of different kinds of drugs. The study was a cross-sectional survey of a total population aged 45-69 years, conducted in 2 municipalities in southwestern Finland. Altogether 1821 people (80% of those invited), 815 men and 1006 women, took part in the screening. The subjects were examined by a questionnaire mailed beforehand and checked in a personal interview. The questionnaire contained questions about the currently used drugs and Goldberg's questionnaire on mental health. Half of the people examined used prescribed drugs currently, more women used drugs than men, and the use of drugs increased with age. Mental symptoms measured with the Goldberg Index appeared in one fifth of the subjects, showing a slight increase with age. Men with mental symptoms showed a fourfold psychotropic drug use compared with the men without mental symptoms. The women with mental symptoms showed a threefold use of psychotropic drugs compared with the women without mental symptoms. Similar differences were found also in other drug groups, for example cardiac glycosides, other cardiovascular drugs, analgesics and drugs for respiratory and digestive organs. Persons with mental disorders showed a high tendency to drug use, also when those drugs had no direct attachment to the mental problem. Men seemed more liable to somatization of mental problems than women.
