Abstract

Background: The maximal static respiratory pressure (MRP) assessment is vital for both clinical reasoning and respiratory system growth and development. The predicted normal values of maximal inspiratory pressures (PImax) and maximal expiratory pressures (PEmax) published for the western population may not be appropriate for Indian children because of the ethnic difference and large inter-subject variations of PImax and PEmax values. Objective: The purpose of the study was to establish normative values of MRP in healthy children aged 8-12 years. Methods: A cross-sectional study was conducted among nine government and public schools of Bangalore, India. We assessed the anthropometric measures (height, weight, BMI, waist-hip ratio, pulmonary function tests) and MRP for 887 children (490 boys and 397 girls) following guidelines by American Thoracic Society/European Respiratory Society. Results and conclusion: The mean of PImax and PEmax were 60.83+19.5 and 62.26+18.13 cmH2O, respectively. The mean of PImax was relatively lower by mean of 15.32 cmH2O when compared from Brazilian, 12.2 cmH2O from Mexican, and 16.23 cmH2O from the Australian population. Similarly, the mean of PEmax of the current study was relatively lower by mean of 27.625 cmH2O when compared from Brazilian, 21.845 cmH2O from Mexican, and 24.365 cmH2O from the Australian population. This states that ethnicity has a strong influence on respiratory muscle strength. Thus, the study provides the normative data for maximal static respiratory pressures for healthy children aged 8-12 years in Bangalore, India
