The "standard" values of pulmonary function tests obtained from Western populations do not agree with that of people of Bangladesh. The present study was conducted with a view to determine the values of lung function parameters such as vital capacity, forced vital capacity and forced expiratory volume in one second for healthy Bangladeshi population from two different income group with different living conditions. 300 non-smokers of age group 20-40 years were selected for the study of which 150 were university students and employees and 150 were slum dwellers of low income group. In addition, 150 female subjects were also included in the study in order to compare the lung function parameters with those of male subjects. The lung function values correlated positively with height and weight, and negatively with age. There is a definite effect of aging on lung function showing a declining trend from age 35 years onwards. The slum dwellers showed lower values of lung functions than the other group. The difference decreased with age. Prediction equations were set up using height, weight and age as parameters. The lung capacity of the female population was found to be lower than that of the male population. In general the lung function values were found to be 80% of the European Standards.

Lung function parameters of bangladeshi people in different living conditions

The "standard" values of pulmonary function tests obtained from Western populations do not agree with that of people of Bangladesh. The present study was conducted with a view to determine the values of lung function parameters such as vital capacity, forced vital capacity and forced expiratory volume in one second for healthy Bangladeshi population from two different income group with different living conditions. 300 non-smokers of age group 20-40 years were selected for the study of which 150 were university students and employees and 150 were slum dwellers of low income group. In addition, 150 female subjects were also included in the study in order to compare the lung function parameters with those of male subjects. The lung function values correlated positively with height and weight, and negatively with age. There is a definite effect of aging on lung function showing a declining trend from age 35 years onwards. The slum dwellers showed lower values of lung functions than the other group. The difference decreased with age. Prediction equations were set up using height, weight and age as parameters. The lung capacity of the female population was found to be lower than that of the male population. In general the lung function values were found to be 80% of the European Standards.
