A study on the various anthropometric determinants of forced vital capacity in male subjects

Ayesha Anjum, Vanajakshi B J.


Background: The lung function tests are a group of tests that measure the lung functions. These tests give a comprehensive evaluation of the respiratory system in an individual. They are an indispensable tool for clinical evaluation of respiratory health and disease.[1] One such important parameter or lung volume is the forced vital capacity (FVC). Anthropometric parameters are a series of quantitative measurements of the muscle and bones. The parameters used to assess the composition of the body are height, weight, body mass index (BMI), etc. Almost all the lung function values are based on the anthropometric measurements. A deviation of the lung parameters from normal values can help us to detect various abnormalities.

Aims and Objectives: The aim of this study is to determine the various anthropometric parameters that determine FVC in young subjects.

Materials and Methods: The study was done at Raichur Institute of Medical Sciences, Raichur. Fifty healthy male subjects with no history of respiratory diseased were selected for the study. Institutional Ethical Clearance was obtained. An informed consent was taken from all the subjects. The procedure for recording the parameters was explained to all the subjects. The height was measured in centimeters and weight was measured in kilograms. Basal metabolic index was calculated for all the subjects. FVC was measured using the digital spirometer. The readings were recorded and noted. The association of various anthropometric parameters to FVC was studied and compared.

Results: On analyzing the relation between FVC and height, it was found that thus relation was statistically highly significant as P < 0.001. On comparing FVC with weight, it was found that this relation was statistically significant as P < 0.05. The association of FVC with BMI was also found to be statistically not significant.

Conclusion: The study concluded that the FVC is determined by anthropometric parameters. Height being the most important determinant followed by weight.

Key words: Height; Weight; Forced Vital Capacity; Male; Anthropometry
