A Study of Spirometry in Obese and Non Obese Asthmatics

This is the authors' abstract. We don't add key points for this paper.

Total of 104 patients were studied with an average age of 47.952 + 16.9112, with 77% of the patients being male.The maximum no of patient were of the middle aged adult males age group 31 -40.The study comprised of 104 individuals of which 79 patients were males and 25 were females.The average weight of the 104 patients was 68.615 kg .The body mass index of our patients had a mean of 26.146 with a minimum BMI of 14.382 a maximum BMI of 48.828.Forced expiratory volume in 1 st second in our OBESE asthmatics was 1.78 ± 0.8150.&Forced vital capacity in the obese group was 2.102 ± 0.8638 .FEV1% was > 70 % in all the patients of the study population demonstrating no fixed airflow limitation in patients of our study population .ERV in the obese groups was .441± 0.2190 liters.The inspiratory capacity in the obese group was 1.771 ± 0.6628 liters .No significant statistical correlation was demonstrated in between the obese and no obese group .Significant correlation was demonstrated between BMI & Waist Circumference.BMI correlated with FEV1, FVC, FEV1% in the study population and a negative correlation was demonstrable.A statistically significant co relation could not be established between BMI & the dynamic spirometric variables.BMI correlated with ERV & VC in the study population and a negative correlation was demonstrable.A statistically significant co relation could not be established between BMI & the static spirometric variables.Waist circumference correlated with the FEV1, FVC, FEV1% in the study population and a negative correlation was demonstrable.A statistically significant co relation could not be established between waist circumference & the dynamic spirometric variables.Waist circumference correlated with ERV & VC in the study population and a negative correlation was demonstrable.A statistically significant co relation could not be established between waist circumference & the static spirometric variables.
