Foundation

bronchial asthma is one of the most prevalent chronic diseases in childhood. The guidelines for diagnosis and treatment are governed by severity, level of control and quality of life, however, there is no evidence that demonstrates its statistical association.

Objective

to measure the association degree between the severity of bronchial asthma, control level and quality of life in children.

Methods

cross-sectional study, carried out from January to December 2022, in a sample of 189 patients with a bronchial asthma confirmed diagnosis. The analyzed variables were: age, sex, severity, level of control and quality of life. Statisticians, absolute frequency, percentage, arithmetic mean and standard deviation were calculated. The Chi-square test (p<0.01) was used to measure association and the V-Cramer coefficient was used to evaluate the strength of the association.

Results

the mean age was 9.17 years (SD ± 0.67). Males predominated, representing 53.54%. Intermittent asthma (39.15%), partial control level (59.79%) and high quality of life (50.26%) prevailed. When relating severity with level of control, the association statistician indicated X2=190.461 (VC= 0.662); in the case of severity and quality of life, X2=252.673 (VC=0.762); and between level of control and quality of life, X2=66.733 (VC=0.401).

Conclusions

there was a strong association between severity of bronchial asthma-level of control and between severity of asthma-quality of life; as well as a moderate association between level of control-quality of life.
