Mortality associated with depression: a forty-year perspective from the Stirling County Study.

Background: This report concerns long-term mortality risks associated with depression, and the potentially confounding factors of alcoholism and cigarette smoking, as experienced by a general population assessed at a baseline in 1952, followed for re-assessment of survivors in 1968, and for death by 1992.

Methods: Self-report and physician-report information was gathered in 1952 and again in 1968 about a sample of 1,079 adults. At the end of follow-up in 1992, the vital status of all subjects was known.

Cell type specificity of lung cancer associated with arsenic ingestion.

Arsenic is a well-documented human carcinogen. Previous studies on urinary bladder and skin cancers have shown that arsenic can cause specific cell types of malignancy. To evaluate whether this is also true for lung cancers, we conducted a study on 243 townships in Taiwan.

Site-specific cancer incidence and mortality after cerebral angiography with radioactive thorotrast.

Few opportunities exist to evaluate the carcinogenic effects of long-term internal exposure to alpha-particle-emitting radionuclides. Patients injected with Thorotrast (thorium-232) during radiographic procedures, beginning in the 1930s, provide one such valuable opportunity. We evaluated site-specific cancer incidence and mortality among an international cohort of 3,042 patients injected during cerebral angiography with either Thorotrast (n = 1,650) or a nonradioactive agent (n = 1,392) and who survived 2 or more years.

Cigarette smoking in relation to depression: historical trends from the Stirling County Study.

Objective: Building on findings about the prevalence and incidence of depression over a 40-year period, the authors provide data on trends in cigarette smoking and associations with depression.

Method: Data come from interviews with adult population samples (1952, 1970, and 1992) and followed cohorts (1952-1970 and 1970-1992). Logistic regression models and survival regressions were used to analyze the data.

Incidence of major depression: prediction from subthreshold categories in the Stirling County Study.

Background: Validity of the newly-proposed categories of Minor Depression (MinD) and Subsyndromal Depression (SSD) would be strengthened if they were found to be related to the incidence of Major Depressive Episode (MDE). In this report, the subsequent incidence of MDE was assessed in terms of baseline evidence about the two subthreshold categories and Dysthymic Disorder (DysD).

Methods: The Diagnostic Interview Schedule was used to interview 489 subjects twice between 1991 and 1995 as part of the Stirling County Study.

Self-disparagement as feature and forerunner of depression: findings from the Stirling County Study.

Sleep disturbance has attracted considerable attention as an early indicator of depression. However, three epidemiologic investigations have shown psychological symptoms, such as self-disparagement, to be stronger predictors. This report examines the depressive symptoms commonly assessed in modern epidemiologic surveys and estimates the generalizability of this information using data from the Stirling County Study, a long-term epidemiologic investigation of psychiatric disorders.
