The approach most often used to measure AHA is Rowe and Kahn's Satisfactory Ageing model. Nonetheless, this model has limitations. One of the strategic objectives of the WHO Global Strategy and Action Plan (2016) is to improve Healthy Ageing measurement. Our objectives were to compare two models of assessing AHA and further compare the results by country and sociodemographic variables.This was a cross-sectional, observational analysis of a representative sample of the general population aged 50 years and older in Europe. The data analysed were obtained by the Study of Health, Ageing and Retirement in Europe (SHARE). The dependent variable was AHA and its dimensions, measured using the Rowe and Kahn AHA model (AHA-B) and the authors' model based on the WHO definition (AHA-BPS). A descriptive analysis and multivariate models of binary logistical regression were developed.The sample consisted of 52,641 participants (mean age 65.24 years [SD = 10.18; Range = 50-104], 53.2% women). Healthy Ageing prevalence in the AHA-B model was 23.5% (95%CI = 23.1%-23.9%). In the AHA-BPS model, this prevalence was 38.9%. In both models, significant variations were observed between countries, and were distributed along a north-western to south-eastern gradient. The sociodemographic variables associated with the absence of AHA were advanced age, female sex, death of spouse, low educational level, lack of employment, and low financial status. Comparing the two models, the strength of association between absence of AHA and advanced age (85 years and older) was four times greater in the AHA-B model.Our results showing differences between these two models provide evidence that the AHA-BPS model does not penalize older age and is more likely to characterize AHA from a health promotion perspective.Bosch-FarréCristinaC0000-0002-3254-6601Health and Healthcare Research Group, University of Girona, Girona, Catalonia, Spain.Nursing Department, University of Girona, Girona, Catalonia, Spain.Garre-OlmoJosepJGirona Biomedical Research Institute (IDIBGI), Salt, Catalonia, Spain.Healthcare Institute (IAS), Salt, Catalonia, Spain.Department of Medical Sciences, University of Girona, Girona, Catalonia, Spain.Bonmatí-TomàsAnnaANursing Department, University of Girona, Girona, Catalonia, Spain.Malagón-AguileraMaria CarmeMCHealth and Healthcare Research Group, University of Girona, Girona, Catalonia, Spain.Nursing Department, University of Girona, Girona, Catalonia, Spain.Gelabert-VilellaSandraSNursing Department, University of Girona, Girona, Catalonia, Spain.Fuentes-PumarolaConcepcióCHealth and Healthcare Research Group, University of Girona, Girona, Catalonia, Spain.Nursing Department, University of Girona, Girona, Catalonia, Spain.Juvinyà-CanalDolorsDHealth and Healthcare Research Group, University of Girona, Girona, Catalonia, Spain.Nursing Department, University of Girona, Girona, Catalonia, Spain.engJournal Article20181029
