Ventilatory function test values of health adult Jordanians.

Annals of Human Biology

1988

Pulmonary function measurements were made in 104 healthy non-smoking men from Calcutta with an age range of 20-59 years. Except for peak expiratory flow rate (PEFR), all the measurements were made with the help of two 9L closed-circuit type expirographs using standard spirometric techniques. PEFR was recorded by two Wright peak flow meters. Prediction formulae were derived on the basis of age and height for all the ventilatory tests except for FEV1%, FET and PEFR. These were predicted from age only. The prediction equation for VC, FVC, FEV1, FEV1%, MVVF and PEFR were reliable, but those for forced expitatory flows and time were not. The FVC and FEV1 values of the present subjects, standardized for age and height, were much lower than those of Americans, Caucasians, Europeans and Canadians but similar to those of Pakistani healthy adults. On comparison with the data reported from other parts of our country, it was revealed that the VC and FEV1 values of the current study, after adjustment of age and height, were much higher than those of southern Indians but comparable with those of north-western Indians.

“…Morris et al (1971) and Sliman et al (1981) worked in an environment that was free of pollutants. This might also have produced a favourable effect on lung function.…”

Pulmonary function studies in healthy non-smoking men of Calcutta

Saha

Annals of Human Biology

1988

“…The sensitivity of a given test in the detection of magnitude and direction of disturbed lung function will, therefore, depend upon the precise definition of the normal values in a cross-section of the general population being tested. Several investigators in different parts of the world have reported on the normal ventilatory standards (Morris, Koski and Johnson 1971, Schmidt, Dickman, Gardner and Brough 1973, Higgins and Keller 1973, Williams, Miller and Taylor 1978, Sliman, Dajani and Dajani 1981. In India a few such studies have been done (Mason 1932, Krishnan and Vareed 1933, Rao, Sengupta, Saha and Devi 1961, Jain and Ramiah 1967, Kamat, Tyagi and Rashid 1982.…”

Pulmonary function studies in healthy non-smoking women of Calcutta

Annals of Human Biology

Saha

1993

Pulmonary function measurements were made in 230 healthy non-smoking women from Calcutta with an age range of 20-59 years. The tests consisted of vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in one second (FEV1), forced expiratory volume in one second as a percentage of forced vital capacity (FEV1%), forced expiratory time (FET), maximum voluntary ventilation, uncontrolled frequency (MVVF), forced expiratory flow (FEF200-1200ml), forced mid-expiratory flow (FEF25-75%), forced end-expiratory flow (FEF75-80%) and peak expiratory flow rate (PEFR). Except for PEFR, all the measurements were made with the help of two 9-litre closed-circuit-type expirographs using standard spirometric techniques. PEFR was recorded with the help of two Wright peak flow meters. Prediction formulae were derived on the basis of physical characteristics. Age and height were found to be the significant predictor variables for VC, FVC and FEV1, while only age was significant for FEV1%. The FVC and FEV1 values of the subjects, standardized for age and height, are much lower than those of Americans, Europeans and Jordanians. On comparison with data reported from other parts of India, it was revealed that the VC and FEV1 values of the current study, after adjustment for age and height, were much higher than those of Southern Indians but comparable with those of North-Western Indians.

“…PFTs reported in American, Jordanian, and European populations were much higher than the currently studied population (23,31,35,44,45). Better socioeconomic status and nutritional habit, superior outdoor practices and enhanced growth of their thoracic cage as well as musculoskeletal system might be the cause of such higher PFTs in those overseas populations.…”

Pulmonary function in young females of Kolkata, India – Revisited

et al. 2016

Rapid economic and industrial growths imposed significant impact on human health including the pulmonary health. Questions were raised regarding the validity of the existing prediction norms of pulmonary function tests (PFTs) in a particular population. The present study was conducted to investigate the applicability of the existing norms for PFTs in young healthy non-smoking female university students of Kolkata, India. Significant difference was noted in vital capacity (VC), forced vital capacity (FVC), and forced expiratory volume in 1 s (FEV 1 ) when the present data were compared with the earlier study in similar population. Correlation statistic revealed significant relationship of age and body height with all the PFT parameters. Body mass had significant correlation with VC, FVC, FEV 1 as a percentage of FVC (FEV 1% ), and peak expiratory flow rate (PEFR). Regression equations have been computed for predicting PFTs from age and body height. There has been a change of PFTs in the studied population for the last couple of decades due to increased environmental pollution in the course of economical and industrial developments. Regression equations computed in this study are not only recommended to predict PFT parameters in the studied population, but they are also considered more reliable owing to their substantially smaller standard error of estimate than those proposed in the previous study.
