Berkelman R L (Division of Surveillance and Epidemiologic Studies, Epidemiology Program Office, Centers for Disease Control, Atlanta, Georgia 30333, USA) and Buehler J W. Public Health Surveillance of non-infectious chronic diseases: The potential to detect rapid changes in disease burden. International Journal of Epidemiology 1990, 19: 628–635.
The usefulness of surveillance in relating chronic disease trends to recent changes in risk exposures is often questioned on the grounds that these trends respond slowly, reflecting long periods between aetiological exposures and clinical onset of disease. We challenge this preconception on the basis of a review of several important risk factors and diseases: alcohol and liver cirrhosis; tobacco and stroke, cardiovascular disease, and lung cancer; and oestrogens and endometrial cancer. Data from cohort, cross-sectional, and modelling studies demonstrate that the time between removal of exposures and the onset of decline in morbidity or mortality is not defined by the time between initial exposure and disease occurrence. Rather, the pattern of lifetime exposures (with recent exposures often having a dominant effect), the dynamics of the disease process, and the segment of the population with reduced exposures determine how soon the decline begins.
