Spirometry is a cheap, simple and repeatable method that follows even small changes in spirometric values thus precisely quantifying the decline of spirometric values, either as a result of a slow natural aging process or rapid changes influenced by various harmful substances.
THE AIM: The primary goal of the study was to establish the influence of aging on the natural decline of spirometric values. The secondary goal was to study the influence of smoking on spirometric decline. METHOD: 89 male workers of the Cable Factory were investigated. They worked in the part of the factory called "Rubber and Plastic" on jobs like preparing of materials, isolation, branding and checking cables. Pulmonary function was assessed by means of a "bell spirometer". For the retrospective study, longitudinal method of following spirometric results was used. RESULTS: Average decline of IVC and FEV1 in the youngest group of patients (26-35 years of age) was 25.9ml/year for IVC and 29.9ml/year for FEV1. The oldest group (over 55 years of age) showed a decline of 42.7ml/year for IVC and 48.6 for FEV1. Non-smokers showed a decline of 22.6ml/year for IVC and 26.7ml/year for FEV1, smokers 36.0ml/year for IVC and 46.7ml/year for FEV1. T test evidenced a statistically highly significant difference comparing the average values of decline in smokers and non-smokers IVC (p<0,001) and FEV1 (p<0,001). In other groups highly significant differences were not proved between neighbouring but between alternate age intervals. CONCLUSIONS: The age dependent decline of spirometric values does exist. The influence of tobacco smoking on the decline of spirometric values is significant.
Key words: spirometric values, decline, FEV1, smoking
