Correlation of gender and anthropometric measurement with pulmonary function tests among undergraduate medical students

Abstract

Introduction: This study aimed to evaluate the effect of gender and anthropometric measurement on pulmonary functions (forced vital capacity [FVC], forced expiratory volume in 1st s [FEV1] and peak expiratory flow rate [PEFR]) of undergraduate medical students to emphasise the need for further research on the aetiology and the prevention of respiratory diseases. Materials and Methods: This cross-sectional study was conducted in the Department of Physiology, Chittagong Medical College (CMC), Chattogram, Bangladesh, from July 2017 to June 2018. A total of 100 participants, aged between 18 and 20 years, studying in the 1st year in CMC, were included by a random sampling method. The participants filled out a questionnaire with general information about previous diseases, medication and family history. Fifty male participants were enrolled in the study group according to inclusion and exclusion criteria. Age and body mass index matched another 50 female participants were included. Respiratory parameters such as FVC, FEV1 and PEFR were measured by a digital spirometer (Chestgraph HI-101, Japan). Readings were taken in normal upright sitting posture. The statistical tests utilised were unpaired Student's t-test and the correlation coefficient conducted using SPSS for windows version 23. Results: Female participants showed significantly lower FVC, FEV1 and PEFR than males. This study observed a significant positive correlation between height and weight and FVC, FEV1 and PEFR. Conclusion: The results of this study help assess pulmonary functions among medical students as pulmonary function tests are one of the indicators of the health status of the individuals.
