Hints & Kinks


Self-reported data on health conditions are frequently used in epidemiological studies since such information often cannot be gathered by other means (Barber et al. 2010). Thus, it is of utmost importance that surveys provide accurate and reliable estimates. Previous studies have indicated that inconsistencies in self-reported morbidity over time vary across health conditions (Beckett et al. 2000; Klabunde et al. 2005; Cigolle et al. 2018). However, the studies are few and have mainly been carried out in specific populations, which makes it difficult to generalize to the entire adult population. The aim of the study was to examine the inconsistencies in 18 health conditions using data from two surveys 4 years apart.


The Danish Health and Morbidity Surveys have been carried out regularly since 1987, aiming to describe the status and trends in health and morbidity in the adult Danish population and factors that influence health status (Jensen et al. 2019). In 2013,...
