Lung function in young Sri Lankan females

Abstract

A study of respiratory function was carried out in 192 adult Sri Lanknd females of age group 19-29 years. Vital capacity (VC), Forcedvital capacity (FVC), forced expiratory volume in one second (FEV1) and maximum voluntary ventilation (MVVF) were measured by spirometry and the peak flow rate by a mini Wright peak flow meter. The d u e s observed were found to be less than that reported for Europeans and closer to thoge af North Indian populations. The relationkhip of thi results to-height and weight was studied. Prediction formulae based on height were derived for some of the tests.

Lung function parameters of healthy Sri Lankan Tamil young adults

“…Lung function parameters were predicted for particular age and height as indicated in Table 4 and 5, and compared with those reported in other studies [6,9,11]. Asians have lower values than Caucasians [6,9,11].…”

Ethnic differences in lung functions of children in the Colombo District, Sri Lanka

“…Balasubramanium et al have compared lung functions of young adult Sinhalese from a higher altitude and young adult Tamils living at sea levels [3,4]. In this comparison, mean values of Sinhalese for FVC, FEV1, FEF25-75 (standardized to height) were higher than Tamil males and lower than Tamil females (p<0.001).…”

“…We enrolled healthy boys and girls aged between 9-15 years from six schools in the Colombo district using multi-stage cluster sampling. Sample size was calculated with a power of 0.8 and 95% confidence interval, based on FEV1values for Tamil females (2.19 ± 0.39 l) and Sinhalese females (2.35 ± 0.405 l) from two studies conducted in Sri Lanka [3,4].…”

“…Balasubramaniam et al reported on spirometry of Tamil females (between 20-28 years) in Jaffna [3]. These values were different to those of Sinhalese female medical students from another study [4]. Balasubramaniam et al concluded that there is an ethnic variation in spirometry between Tamil and Sinhalese females.…”

Spirometry in children: Meeting the unmet need

“…Spirometric and flow standards for healthy non-smoking Sri Lankan young adults belonging to Sinhalese ethnic group and lung function parameters of healthy Sri Lankan Tamil young adults are some of those 12,13,14 .…”
