Pulmonary function of adolescents from Tripura, a North-eastern state of India

Abstract

Objective:Spirometric evaluation of pulmonary function has been evolved as clinical tool in diagnosis, management, and follow-up of respiratory disorders. There are very few studies on normative reference values of pulmonary function parameters for adolescents from Tripura, a North-eastern state of India. The present study was aimed to evaluate pulmonary function and their predictors in male and female adolescents of Tripura.Materials and Methods:A total of 640 (320 from tribal and 320 non-tribal) healthy, non-smoking male and female school children (age 10-14 years) from four different districts of Tripura were randomly sampled for the study. The pulmonary function parameters analysed included forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), peak expiratory flow rate (PEFR), forced expiratory flow between 25% and 75% expired volume (FEF25-75%), ratio of FEV1/FVC and maximum voluntary ventilation (MVV).Results:The results revealed that body weight, body mass index (BMI), PEFR, FEF25-75% and MVV are significantly high among male tribal children in comparison to non-tribal children. Height, weight, waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), PEFR and MVV were found to be significantly more in tribal girls. In case of adolescents from Tripura, most of the pulmonary function parameters correlated with anthropometric parameters of the subject like height, weight, BMI, WHR, and WHtR.Conclusion:From the present study, it can be concluded that both anthropometric and pulmonary function status of tribal and non-tribal adolescents from Tripura are comparable. The computed regression norms may be used to predict pulmonary function of adolescents from Tripura by using anthropometric indices.

“…5,6 But we found Waist to Hip ratio to be negatively correlated to FVC, FEV1, PEFR and FEF25-75 which was inverse to Choudhuri who found positive correlation. 17 We studied relationship between body fat (total body fat, trunk subcutaneous fat and whole body subcutaneous fat) and lung function parameters, we found total body fat, trunk subcutaneous fat and whole body subcutaneous fat found to be negatively correlated to FVC, FEV1, PEFR and FEF25-75 all the three parameters of body fat were significantly higher in females. Similar results were found with Lad high amounts of fat mass and adiposity may be related to a greater degree of airway narrowing.…”
