Abstract

Objective: The aim of this study was to find the effect of sitting and upright standing postures, factors like height, weight, respiratory rate and ethnicity on spirometric indices of healthy adult Kashmiri individuals and to establish a prediction equation on basis of these factors.Method:  After the screening, 52 (100%) subjects were recruited. Among them, 14 (26.9%) were female and 38(73.1%) were male, mean age was 19.54±1.02 years, height was 170.77±7.93 cm, weight was 67.69±12.33 kilograms, body mass index was 23.077± 3.18, and respiratory rate was 18.46±3.62 per minute. Under standard condition for all, they performed spirometry in two positions sitting and standing. Data was recorded trice and interpreted by STATA 14.1. Paired t test was applied for finding relation of spirometric indices with body postures and multiple regression test with biometric values. Prediction equation was also derived.Results:  No significant difference was found between spirometric indices and both body position. However, changing the body position, height and weight affected some variables whereas, respiratory rate did not show any significance result.Conclusion: In adult Kashmiri population, spirometry can be done in bothrecommended positions. It appeared that height and weight has sound effecton FVC, FEV1sec, MVV and FVC, FEV1sec/FVC respectively whereas, respiratoryrate has no effect on spirometry while changing the body position.
