      In this study, the largest Nordic study of its kind, investigated psychosexual dysfunction among subjects aged 55-57 years. The cohort included 862 subjects of both sexes and all were interviewed using the Diagnostic Interview Schedule (DIS). Results showed that 122 subjects had a lifetime diagnosis of psychosexual dysfunction. The lifetime prevalence of psychosexual dysfunction was 14.4%; of inhibited sexual desire, 9.8%; of inhibited sexual excitement, 3.5%; of inhibited orgasm, 2.1%; and of functional dyspareunia, 1.3%. Of the subjects with psychosexual dysfunction, 73% were women. The frequency was highest in those who had never married. Separated subjects had rates intermediate between the married and the never-married. The majority (76%) of affected subjects had only one dysfunction. However, 57% of them had received another psychiatric diagnosis at some time. Subjects with psychosexual dysfunction were less frequently diagnosed as suffering from alcohol abuse and dependence and social phobia than subjects with no psychosexual dysfunction.

      This paper presents the 1-month, 6-month and 1-year prevalence rates for mental disorders in a random sample of people born in Iceland in 1931 and interviewed at the age of 55-57 years. The diagnoses were made according to DSM-III, on the basis of the National Institute of Mental Health's Diagnostic Interview Schedule (DIS) used by trained lay interviewers. The period prevalence rates were found to be similar to those obtained by other studies using the DIS as a survey instrument. The highest rates were among the widowed, separated or divorced. The 1-year symptom-free rates were high for alcohol abuse and alcohol dependence, 74% and 71%, respectively. For depressive disorders, the 1-year symptom-free rate was only 50% and for the anxiety disorders, 50%-65%. The most common psychiatric disorders had a chronic course.
