Correlation of BMI Variation with Tidal Function in Healthy Young Adults.
J Islamic Int Med Coll Jan ;14(3):136-41.

Objective: To observe the effect of Body Mass Index (BMI) on Tidal volume and its rate of air flow in healthy young adults. Study Design: Cross-sectional study Place and Duration of Study: Department of Physiology at Shalamar Medical and Dental College, Lahore, from th th 14 April to 20 August 2018. Materials and Methods: Thirty students with fifteen boys and fifteen girls were involved in the study. Convenience sampling technique was used for First year Medical Undergraduate students, aged 19-21 years; also consent was taken each participant. All the subjects were healthy and not on any medication or involved in endurance training program. Power Lab with spirometer pod and pneumotacho meter was used to measure Tidal volume and its air flow rate. Data was collected through application namely "Respiratory Airflow & Volume" in Lab Tutor software. BMI values were taken in kg/cm via "Adult weighing scale". Linear regression analysis was performed to see the effect of BMI on tidal volume and its rate of air flow. Results: In both genders BMI was not proved a predictor of Tidal volume (L) nor it was proved a predictor of Tidal air flow rate (L/min) in healthy young adults resulted through regression analysis. Where Tidal volume and its rate of flow were taken as dependent variables and BMI was considered as independent variable, however the results proved statistically insignificant p-value (>0.05). Conclusion:BMI has no correlation with Tidal volume and its air flow rate in healthy young adults.
