Sleep-disordered breathing and daytime sleepiness predict children's reading ability

Area of Science:

• Child Psychology
• Developmental Neuroscience
• Educational Psychology

Background:

• Sleep problems are prevalent in children, negatively impacting cognitive and academic development.
• Early identification of factors affecting reading is crucial for academic success.

Purpose of the Study:

• To examine the relationship between sleep issues and reading abilities in children.
• Investigate the impact of sleep on oral word and non-word reading performance.

Main Methods:

• Cross-sectional study of 339 children aged 4-14 years.
• Utilized parent-reported sleep questionnaires and the Test of Word Reading Efficiency.
• Employed hierarchical multiple linear regression to analyze sleep problem predictors of reading speed.

Main Results:

• Parent-reported sleep problems (sleep-disordered breathing, daytime sleepiness, short sleep latency) predicted poorer word and non-word reading.
• Sleep issues accounted for 6-7% of the variance in reading scores.
• Adverse sleep factors were associated with reduced sight word reading and phonemic decoding efficiency.

Conclusions:

• Sleep problems are significantly associated with reading difficulties in children.
• Interventions targeting sleep may benefit children with reading challenges.
• Recommends screening for sleep problems in children with literacy difficulties and vice versa.
