Effect of the Buteyko breathing technique on asthma severity control among school age children

ABSTRACT:

Background

Asthma is a complex condition that can impair not only the child’s physical growth but also his optimal functional capacity and performance. Buteyko breathing technique is an exercise designed to regulate the breathing process. This study aimed to evaluate the effect of the Buteyko breathing technique on asthma severity control among school-age children. In Egypt, this technique was applied through five studies, four among adult patients and only one among children. In Mansoura University, only one study conducted among adult patients and no studies conducted among children. Therefore, to fulfill this gap of knowledge, it was necessary to study the effect of this technique on asthma severity control among school age children.

Results

The mean childhood asthma control pretest was significantly improved in the posttest with high mean percent change of posttest than pretest (p = 0.0001), which was clinically and statically high significant. There was a statistical significant increase in the mean of peak expiratory flow rate and control pause test at the fourth week than the first one (p = 0.0001), with a high significant mean percent of change. There was a significant decrease in the heart rate over the 4 weeks of follow-up with high mean percent changes at fourth week than the first one (p = 0.003).

Conclusions

This study supports the effectiveness of the Buteyko breathing technique in improving respiratory outcome and promoting asthma control among school-age children with bronchial asthma.

Project description:RationaleSleep-disordered breathing (SDB) in children is associated with cognitive challenges. However, potential associations between SDB severity and neurocognitive function, as well as the presence of an SDB cutoff, have not been fully explored.ObjectivesTo determine whether SDB-associated adverse changes in neurocognitive functioning are severity dependent.MethodsA total of 1,010 snoring and nonsnoring children ages 5-7 years were prospectively recruited from public schools and underwent polysomnography and neurocognitive assessments of intellectual, attention, memory, language, and executive function development. The children were subdivided into four severity groups on the basis of apnea-hypopnea index (AHI), followed by comparisons of cognitive function, with a particular focus on standardized subtests of intellectual, language, attention, memory, and executive function.Measurement and main resultsDifferential Ability Scales Verbal (P < 0.001) and Nonverbal (P = 0.002) performance, as well as global conceptual ability (IQ) (P < 0.001) scores, differed significantly across the groups, with individuals with higher AHI showing worse performance. Additionally, specific NEPSY (a Developmental Neuropsychological Assessment) subscores focused on attention and executive skills differed across the groups, indicating differences in levels of engagement and problem solving. Children with higher AHI (>5 per hour of total sleep time) were significantly more impaired than all three lower AHI groups, indicating a dose-response impact of SDB.ConclusionsThis large community-based sample of children highlights the significant deleterious impact of SDB, particularly in children with moderate to severe obstructive sleep apnea, and also that even snoring alone affects neurocognitive function. By affecting developing capabilities, as illustrated by cognitive measures in a severity-graded manner, SDB could adversely impact children's capacity to attain academic and adaptive goals, ultimately hampering their ability to reach independence. Our findings support the need for increased awareness of SDB, with particular emphasis on children with more severe obstructive sleep apnea.
