Abstract
Abstract: Respiratory diseases represent the most common cause of death in children. Allergic respiratory disorders in particular asthma are increasing in prevalence. Prevalence of asthma in Indian children is found to be as high as 4.75%. This cross sectional prospective study was conducted to establish normal values of PEFR for children of south odisha. PEFR is a lung function test which is easily measurable and reproducible but baseline value of PEFR has not been studied in Odisha. The aim of this study is to establish normal values of PEFR in normal children of Berhampur(5-14 Years).To find out the correlation of various anthropometric parameters with PEFR. Derive predictive equations correlations PEFR with age, weight and height. A total of 708 normal school going children 5-14 years were selected randomly to obtain PEFR form 3 different schools of Berhampur,(prominent city of south odisha). The miniWright peak flow meter was used to measure peak flow rate in a standard way. The highest of 3 reading was taken as the correct value. Anthropometric parameters including height, weight, age, gender were recorded appropriately and body mass index was calculated. Data were analysed by Microsoft WORD, EXCEL, Graph pad instat. Strong correlation was found between PEFR with height, weight, age, BMI. Correlation of PEFR was best with height, followed by with weight, age and BMI. Though the mean PEFR of boys are more than girls, there was no significant difference in the same, when similar height is taken into consideration. The PEFR value of children of Berhampur was less than that of other parts. This indicates PEFR is variable according to geographical situation, environmental condition, life style of people etc. PEFR (l/min) predicted form height based regression equation was the most consistent finding in a good number of studies including present one. Regression equation calculated taking height as variable is as follows, PEFR for Boys =4.591*Height(cm)-393.03. PEFR for Girls =3.198*Height(cm)-217.92. Our results appear to be reliable due to high correlation coefficient with body parameters and can be used as a normal reference value for normal children of southern odisha for 5-14 years years age group. PEFR correlated best with height, followed by with weight, age, BMI.Though mean PEFR of boys is little more than girls, there is no significant difference of PEFR between boys and girls for same height. PEFR for Boys =4.591*Height(cm)-393.03, PEFR for Girls =3.198*Height(cm)-217.92. The PEFR value of children of Berhampur is less than that of other parts.(From the available data).This implies PEFR varies with geographical situation, environmental condition, life style of population. Results of this study can be used as a standard (PEFR value) for children of 5-14 year age group of southern odisha. Keywords: PEFR, anthropometry, asthma.
