The Effect of Ageing on Vital Capacity and Peak Expiratory Flow Rate in Healthy Non-Smoking Agricultural Workers
Journal Title: International Journal of Medical and Health Sciences - Year 2012, Vol 1, Issue 4
Abstract
Background: Agricultural workers have an increased risk of respiratory diseases. Occupation and age among many other factors influence the lung function. Growing body of scientific literature from oversees have highlighted the decline in lung function with age in farmers and farm related workers. The aim of the present study was to assess the age related decline in lung function in agricultural workers since most of the Indian studies reported age related decline in lung function in general population but none in agricultural population. Methods: A total number of 64 healthy, non-smoking agricultural workers were divided into two groups according to their age. First group consisted of 31 subjects aged between 20-25 years and the second group consisted of 33 subjects aged between 26-40 years. Vital capacity (VC) and Peak Expiratory Flow Rate (PEFR) were measured using spirometry in both the groups. Vital Index was calculated from the vital capacity and body surface area. Results: Peak Expiratory Flow Rate was decreased significantly with advancing age in agricultural workers but not the Vital Capacity. Conclusion: Both obstruction to the air flow and senile degenerative changes in the lungs together might have played role in decreased PEFR in agricultural workers. KEYWORDS: Age, Vital Capacity, PEFR, Agricultural Workers.
