Lung age in women with morbid obesity.

Objective: To investigate the influence of morbid obesity on the lung age in women and to correlate with body mass, body mass index (BMI), and ventilatory variables.

Methods: This was a cross-sectional study with 72 morbidly obese women and a control group consisting of 37 normal weight women. The subjects performed a pulmonary function test to determine lung age, and the results were correlated to anthropometric variables and lung volumes.

Behavior of respiratory muscle strength in morbidly obese women by using different predictive equations.

Background: Studies on the behavior of respiratory muscle strength (RMS) in morbidly obese patients have found conflicting results.

Objectives: To evaluate RMS in morbidly obese women and to compare the results by using different predictive equations.

Method: This is a cross-sectional study that recruited 30 morbidly obese women and a control group of 30 normal-weight women.
