Outcomes between different validated questionnaires to assess the level of physical activity in cardiac patients adhering to a rehabilitation program

Abstract

Abstract Introduction The International Physical Activity Ques-tionnaire (IPAQ) and Baecke inventory are commonly used in cardiovascular rehabilitation routines. Thus, it is understood that investigations on the equivalence of outcomes between these two tools may be relevant to measure the magnitude of possible reproducibility and correlations between them. Objective To compare in cardiac patients the level of physical activity obtained through the IPAQ and Baecke inventory and correlate outcomes obtained with a 6-minute walk test. Methods In total, 65 heart disease patients included in a cardiovascular rehabilitation program (40 male and 25 female) were included, with a mean age of 65.8 ± 10.5 years. The data were obtained from the application of a standardized form, containing the proposed study objects, which were the IPAQ and Baecke inventory. In addition, data regarding anthropometric measurements (body mass, height, and body mass index - BMI), waist-to-hip ratio, blood pressure, and performance in the 6-minute walk test were measured. Results The main outcomes refer to the weak association between the instruments evaluated, which showed a strong relationship only between free time physical activity (r = 1), while in the other categories and when compared to the 6-minute walk test, the verified agreement was not significant. Conclusion The questionnaires are strongly equivalent only for free time physical activity, in the other categories and when compared to the 6-minute walk test, the agreement was not significant. Thus, based on the results, implementation in clinical practice considering the use of these tools with equivalence is not recommended.
