Background: PEFR is the easiest and most cost effective method to evaluate respiratory functions. PEFR can be measured by a simple instrument Peak expiratory flow meter. Measuring PEFR has been suggested as an important tool in asthma management by all International guidelines. The aim of this study was to determine the PEFR values in healthy school children of central Karnataka, India.
Method: PEFR was measured in Two thousand and two hundred school children using mini Wright's Peak flow meter. All PEFR measurements were obtained in standing position and the best out of three trials were recorded. Height and weight were recorded. Regression analysis was used to calculate the predicted normal values of PEFR and also to assess its relation to weight and height.
Results: Positive correlation was seen between age, height, weight and PEFR. The boys had higher values of PEFR than girls at all heights. The prediction equation based on height was PEFR = 5.63 (Ht) - 474.43, r = + 0.902 for boys and PEFR = 5.30 (Ht) - 451, r = + 0.876 for girls.
Conclusion: PEFR values in this study were comparatively low to those of North Indian and western school children, High to those of other children of south India. The prediction equation obtained from the study can be used to detect PEFR values in central part of Karnataka.

Background: Hypertension is one of the most common disease prevailing in the developed and developing world and has its ischolar_mains in childhood and adolescence. Blood pressure levels vary with age, sex, height, weight, BMI, family history of hypertension, socio-economic status and ethnic groups.The aim of this study was to determine the blood pressure values in healthy school children of central Karnataka, India.
Method: Blood pressure data of 1651 urban school children (829 boys and 822 girls) in the age group of 6-16 years were analyzed to study the distribution pattern of systolic blood pressure(SBP) and diastolic blood pressure(DBP) at different age, sex, weight,height and BMI. The correlation coefficient and regression coefficient was calculated and prediction equation for systolic and diastolic blood pressure for that particular age, height,weight and BMI were obtained. Normograms according to age were established.
Results: The SBP and DBP tends to increase with age, weight, height and BMI. The blood pressure values (SBP and DBP) increased grossly after 11 years of age. In the normograms obtained in the study, 95% of the study population falls between mean+2SD and mean-2SD.
Conclusion: The blood pressure of children and adolescents can be evaluated using the reference table according to age. The table provided helps to classify as 'normal' or 'hypertension' (>+2SD).
