Influence of socio-economic and demographic factors in determining breathing patterns: a pilot study.
Breathing represents one of the vital functions of the organism, and its unbalance causes some series of alterations in several organs and systems.


OBJECTIVE
Verify the influence of socio-economic and demographic factors in determining breathing patterns.


METHODS
cross-sectional.


METHODS
there were 143 students in the sample, with ages ranging from 9 and 10 years, from two schools, public and private, in the city of Recife, Pernambuco. Breathing patterns were established through two tests: Glatzel Plate (Steam) and water time in the mouth. Socio-economic factors were evaluated through questionnaires with nine questions each. Statistics were carried out by means of the Chi-Squared test or Fishers Exact test and the significance level used was of 5%.


RESULTS
Oral breathing prevalence was of 55.2%, higher among females (57.7%) and in public schools (67.2%). Lack of medical care (62%), less use of medications (56.6%), parents with educational levels lower than high school, divorced parents (66%), students that do not live with their parents (68.7%) and homes with only one room (72%), in all of those situations, oral breathing signs were more prevalent. Only school type had significant association with the breathing pattern.


CONCLUSIONS
High levels of oral breathing without differences concerning gender and age. With the exception of school type, there was no association between breathing pattern and socio-economic factors.
