Obesity is a major public health concern in both developed and developing countries. It has been shown to be a co-morbid condition in a variety of metabolic, cardiovascular, and pulmonary conditions. Only a few research have looked into the link between lung function and body composition in middle-aged obese people.
The goal of this study was to look at the relationship between body composition and lung function in obese middle-aged people.
Methods: The study comprised 100 obese healthy participants between the ages of 35 and 55. Using anticipated formulae, BMI, Body Fat Percentage (BF%), Fat Mass (FM), and Fat Free Mass (FFM) were calculated. All of the recordings were made at the same time of day, from 10 a.m. to 12 p.m., in the same temperature and environment, and respiratory parameters like Forced Vital Capacity (FVC), Forced Expiratory Volume in One Second (FEV1), FEV1/FVC, Peak Expiratory Flow Rate (PEFR), Mean Forced Expiratory Flow during the Middle of FVC (FEF25-75 percent), and Maximum Voluntary Ventilation (MVV The variables were analysed using an unpaired t-test and Pearson's correlation coefficient. Statistical significance was defined as a P value of less than 0.05.
Results: The average BMI of the study participants was 31.91.78 kg/m2. FM was found to have a non-significant inverse relationship with FVC and FEV1. The correlation coefficient between FM and the FEV1/FVC ratio was negative and non-significant. There was no link between FM and FEF25-75 percent in this study. In obese people, there was a substantial positive association between FM and PEFR. FFM had a substantial positive connection with FEF25-75 percent and MVV (r = +0.65 and +0.94, respectively).
Conclusions: The distribution of fat in the lungs is more closely related to pulmonary function than the degree of obesity. When determining early alterations in lung functions in middle-aged obese people, it's critical to consider body composition rather than just BMI.Author(S) Details
