Background: To identify the anthropometric variables in equations/reference values of
impulse oscillometry system (IOS) parameters in preschoolers, children and adolescents.
Method: Systematic search on the databases MEDLINE/Ovid, SCOPUS and SciELO using the key
words “preschool, child and adolescent”, “impulse oscillometry”, “reference values” and its variations.
Results: This review considered a total of 13 articles. The studies presented height, weight, sex and
age as the variables correlated to oscillometric parameters. Most studies do not present the correlation
values of analyzed variables, and only a few presented the results considering gender differences.
The coefficients of determination of the equations were low, specially for the samples including
preschoolers. Height was identified as the most influent predictive variable to IOS parameters
in the studied age group.
Conclusion: Anthropometric variables, especially height, plays an important role determining reference
values/equations for oscillometric parameters, however, the data acquisition method should
