The Psychiatric Neuroscience: Epidemiology Research Unit provides a link between the Harvard Medical School and the Harvard School of Public Health. One of its functions is to provide consultation and training for psychiatric residents and others who wish to include public health in their backgrounds. The main function, however, is research with a focus on the longest ongoing study of psychiatric epidemiology in a general population.
Reports based on the full 40-year perspective indicate that the current prevalence of depression remained stable but in the last quarter of the 20th century a re-distribution occurred based on a two-fold increase among women under 45 years of age with small decreases in the other gender/age groups. Throughout the period of study, depression was almost always accompanied by generalized anxiety. The only change in the relationship between depression and anxiety was that depression began to resemble anxiety as mainly a disorder of women. While it has usually been thought that epidemiologic estimates are unrealistically high, a validity study toward the end of the investigation indicated that clinicians administering the Structured Clinical Interview for Diagnosis suggested that epidemiologic rates may underestimate prevalence.
Over the 40 years, the prevalence of cigarette smoking rose and then declined. In the most recent survey, but not earlier, there was a strong relationship between smoking and depression. The prevalence of obesity increased but was not associated with depression although among those with lifetime depression, the obese subjects were much more likely to gain weight during an episode of depression than the non-obese.
