Marital coital activity in men at the age of 75: relation to somatic, psychiatric, and social factors at the age of 70

Frequency of marital intercourse among patients with psychiatric and psychosomatic disorders in Japan

This study investigated the frequency of marital intercourse in 951 patients with psychiatric and psychosomatic disorders and compared it to that in a normative sample. Only fourteen percent of the patient group had sexual intercourse more than once per week; thirty-nine percent were sexually inactive. The groups of patients with eating disorders, mood disorders, or any mental or behavioral disorders complicated by organic diseases such as cancer, ischemic heart disease, and other physical disorders had fewer mean coital frequencies than the controls, whereas the coital frequency of patients with anxiety disorders, somatoform disorders, sleep disorders, or psychosomatic disorders did not differ significantly from that of controls.

Psychiatric epidemiology of old age: the H70 study--the NAPE lecture 2003

OBJECTIVE

To describe methodological issues and possibilities in the epidemiology of old age psychiatry using data from the H70 study in Göteborg, Sweden.

METHOD

A representative sample born during 1901-02 was examined at 70, 75, 79, 81, 83, 85, 87, 90, 92, 95, 97, 99 and 100 years of age, another during 1906-07 was examined at 70 and 79 years of age, and samples born between 1922 and 1930 were examined at 70 years of age. The study includes psychiatric examinations and key informant interviews performed by psychiatrists, physical examinations performed by geriatricians, psychometric testings, blood sampling, computerized tomographies of the brain, cerebrospinal fluid analyses, anthropometric measurements, and psychosocial background factors.

RESULTS

Mental disorders are found in approximately 30% of the elderly, but is seldom detected or properly treated. Incidence of depression and dementia increases with age. The relationship between blood pressure and Alzheimer's disease is an example of how cross-sectional and longitudinal studies yield completely different results. Brain imaging is an important tool in epidemiologic studies of the elderly to detect silent cerebrovascular disease and other structural brain changes. The high prevalence of psychotic symptoms is an example of the importance to use several sources of information to detect these symptoms. Dementia should be diagnosed in all types of studies in the elderly, as it influences several outcomes such as mortality, blood pressure, and rates of depression. Suicidal feelings are rare in the elderly and are strongly related to mental disorders.

CONCLUSION

Modern epidemiologic studies in population samples should be longitudinal and include assessments of psychosocial risk factors as well as comprehensive sets of biologic markers, such as brain imaging, neurochemical analyses, and genetic information to maximize the contribution that epidemiology can provide to increase our knowledge about the etiology of mental disorders.
