BACKGROUND: This study aimed to examine the impact of Body Mass Index and Waist. The circumference on Pulmonary Function Test spirometry parameters such as FVC, FEV1, PEF and FEF25–75% in the adult population.
METHODS: Twenty-five adult participants (aged between 18 and 50 years) were involved in this study. The participants completed a questionnaire about their weight, height, gender, waist circumference, and medical history. The height, weight, and waist circumferences were obtained in the pulmonary function test lab. Subjects were instructed to perform at least three acceptable forced vital capacity maneuvers by spirometry to meet the acceptability criteria for the American thoracic society (ATS) testing standards; the FVC and FEV1 maneuvers should be within 150 ml for the subject to meet the repeatability criteria. The Body mass index was calculated for all subjects.
RESULTS: The result shows no significant impact of BMI on FVC, FEV1, PEFR, or FEF 25–75% (P values = 0.056, 0.419, 0.413, 0.843, respectively and r values = 0.4, 0.2, -0.2, -0.04, respectively). Also, there was no significant impact found between WC and FVC, FEV1, PEFR, or FEF 25–75% (P values= 0.397, 0.920, 0.359, 0.727 respectively and r values= 0.2, -0.02, -0.2, -0.1, respectively).
CONCLUSION: This study found no significant correlation between BMI and spirometric values (FVC, FEV1, PEFR, or FEF 25–75% ), and no correlation found between WC and spirometric values (FVC, FEV1, PEFR, or FEF25–75%).
