Surveillance of the incidence of non-communicable diseases (NCDS) with sparse resources: A simulation study using data from a national diabetes registry, Denmark, 1995-2004

Abstract

We propose two new methods to estimate secular trends in the incidence of a chronic disease from a series of prevalence studies and mortality data. One method is a direct inversion formula, the second method is a least squares estimation. Both methods are validated in a simulation study based on data from a diabetes register. The results of the validation show that the proposed methods may be useful in epidemiological settings with sparse resources, where running a register or a series of follow-up studies is difficult or impossible.
