Children's sleep quality is linked to phonological working memory and orofacial functions. Better sleep correlates with improved backward digit recall and healthier breathing, mandibular posture, and lip mobility.
Area of Science:
- Pediatric Health
- Speech-Language Pathology
- Sleep Medicine
Background:
- Sleep quality significantly impacts a child's overall well-being and development.
- Oral language skills, auditory processing, and orofacial myofunctional aspects are crucial for child development.
Purpose of the Study:
- To investigate the correlation between children's sleep quality of life and their oral language, auditory processing, and orofacial myofunctional status.
Main Methods:
- Nineteen children underwent otorhinolaryngological and speech evaluations.
- Auditory processing was assessed using various tests, including the dichotic digit test.
- Phonological processing, language, and orofacial myofunctional aspects were evaluated using standardized protocols and tests.
Main Results:
- A significant correlation was found between sleep quality and phonological working memory (backward digits).
- Specific orofacial myofunctional aspects, including breathing, mandibular posture, and lip mobility, also showed significant correlations with sleep quality.
Conclusions:
- Sleep quality in children is associated with phonological processing skills, particularly phonological working memory.
- Orofacial myofunctional characteristics are linked to the sleep quality of life in children.
