Association between cardiorespiratory fitness and cardiovascular risk factors in healthy individuals Background: Cardiorespiratory fitness (FIT) is associated with a better profile in most modifiable cardiovascular risk factors (RF). In Chile, sedentary lifestyle is highly prevalent, reaching almost 90%. Aim: To determine the association between FIT and traditional and emergent RF in a primary prevention population. Material and methods: We prospectively studied 1973 subjects (36% women, mean age 56±13 years) without history of cardiovascular disease and absence of ischemic changes on exercise testing. We assessed cardiovascular RF and determined body mass index (BMI), waist circumference, systolic and diastolic blood pressure, fasting blood lipids, glucose, C-reactive protein (CRP) and fibrinogen. FIT was measured by a self-reported physical activity questionnaire and by a maximal treadmill exercise test, expressed in metabolic equivalents (METs). Results: Subjects in the highest FIT according to the treadmill test had significantly lower BMI, waist circumference, systolic and diastolic blood pressure, total cholesterol, tryglycerides, glucose, CRP and fibrinogen, and higher HDL cholesterol (adjusted by age and gender). LDL cholesterol did not show significant changes. The same pattern of RF (including LDL cholesterol) and CRP was observed when using selfreported physical activity as a FIT parameter. There was a significant association between both methods to measure FIT (p <0.0001, Chi-square Mantel-Haenszel). Conclusions: Our findings show that a better level of FIT, assessed by exercise testing or through self-report is associated with improved levels of traditional and emergent RF (Rev Méd Chile 2009; 137: 737-45).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
