An Appraisal on Pulmonary Function Associated With Seasons, Smoking and Food Habits in Highly Polluted Area

Abstract

At present times environmental changes are evident. Increase of global temperature affects seasons, consequently respiratory dynamics also may be changed. On the other hand, anthropometric parameters, food habits, smoking are also the significant factors which are measured in spirometry can also affect the respiratory efficacy. The present study focuses on the effect of environmental changes including seasons, pollution, smoking and food habits associated with spirometry. For this study a total number of 203 volunteers, both male and female of age group between twenty to fifty years had been selected. The study based on the seasons using result from Spirometry. Anthropometric parameters and spirometric data including FVC (Forced vital capacity), PEFR (Peak expiratory flow rate), FEV1 (forced 1-s expired volume), FEV1/ FVC and FEF 25-75 have been measured for all subjects. The values of data have been tabulated as mean, median and co-efficient variation. FVC, PEFR and FEV1 were increasing in winter though decreasing in summer. Anthropometric parameters, smoking, pollution, food habits and seasons were the important factors which can affect the respiratory efficiency measured in spirometry. Besides with that respiratory rate and functions changes with seasons.
