Abstract

Cardiorespiratory fitness is used as an independent factor for evaluating risk of all-cause mortality, but mainly from coronary heart disease. Nevertheless, evaluation of fitness based on stress tests poses numerous epidemiological difficulties. Alternative forms of evaluation have therefore been suggested using non-exercise-based regression models. This study aimed to analyze these models and their applicability to epidemiological studies. A systematic review was conducted of articles published from 1966 to 2002. The models were classified according to: (a) theoretical justification for the explanatory variables included in the model; (b) validation criteria (gold standard); (c) regression models fully reported, including standard error of estimation; and (d) cross-validation. The search process yielded 23 studies, five of which met all established quality criteria. The authors conclude that cardiorespiratory evaluation by non-exercise-based models could be feasible in epidemiological studies. However, few equations appear to meet the minimum external validation requirements to provide data that could be generalized to large populations.
