A study on predictors of Peak Expiratory Flow Rate in Muslim subjects (aged 18 to 20 years) of Karnataka.

ABSTRACT

This study aims to develop Peak Expiratory Flow Rate (PEFR) predictors for Karnataka Muslim male and female subjects of aged 18 to 20 years. PEFR was recorded in a standing position using mini Wright Peak Flow Meter on one hundred and four (104) healthy male and sixty one (61) healthy female subjects. Anthropometrical measurements i.e. height, weight, body surface area and body mass index were calculated. Statistically significant correlation were found in both sexes between PEFR and standing height (male, r = 0.94, P < 0.001; female, r = 0.95, P < 0.001), weight (male, r = 0.56, P < 0.001; female, r = 0.70, P < 0.001) and body surface area (male, r = 0.68, P < 0.001; female, r = 0.57, P < 0.001). The correlation between PEFR and body mass index were not found statistically significant in both sexes (male, r = 0.081; female, r = 0.17). The prediction equation for Karnataka male and female Muslim subjects (aged 18 to 20 years) based on height, weight and body surface area and multiple regression equation based on all those physical parameters have been developed (PEFR (l/m) (male) = 1.7304 x height + 0.155 x weight + 140.45 x BSA + 5.02; PEFR (l/m) (female) = 2.0448 x height--16.08 weight + 664.697 x BSA--101.24).
