Abstract

Background and Aim of the Study: Obesity is currently one of the biggest social problems and can be assessed using several indicators. The Body Mass Index (BMI) is a simple method to evaluate body fatness. Thus, the effects of BMI on the respiratory system have been increasingly studied in the field of pneumology. The main objective of this work was to verify if there is an influence of BMI on the strength of the respiratory muscles and spirometric parameters. Material and Methods: This study was conducted using a sample that consisted of 374 individuals. For that, the clinical processes of patients who underwent preoperative assessment were consulted and divided according to different BMI classes. The data was analyzed in an encrypted database IBM SPSS Statistics software. Results: The results obtained showed that there are significant statistically differences between maximal inspiratory pressure (MIP) (p-value
