School performance and behavior of Korean elementary school students with sleep-disordered breathing

Area of Science:

• Pediatric Sleep Medicine
• Child Psychology
• Educational Psychology

Background:

• Sleep-disordered breathing (SDB) is linked to growth and behavioral issues in Western children.
• Previous research on SDB's impact on children is predominantly from European and North American populations.
• The effects of SDB on non-Western children's development require further investigation.

Purpose of the Study:

• To examine the association between SDB and school performance in Korean elementary students.
• To assess behavioral disturbances in Korean children diagnosed with SDB.
• To provide culturally specific data on SDB's impact on child development.

Main Methods:

• A survey was administered to parents of 302 third-grade students in Seoul to diagnose SDB.
• Data collected included height, weight, midterm exam scores, and behavioral assessments.
• Statistical analysis compared students with and without SDB.

Main Results:

• Out of 299 surveyed students, 9.7% had SDB.
• No significant difference in body mass index was observed between SDB and control groups.
• While overall academic scores were similar, students with SDB showed significantly higher rates of inattention (58.6%) and lack of self-control (44.8%).

Conclusions:

• SDB is not strongly correlated with poor academic performance in Korean elementary students.
• Behavioral disturbances, specifically inattention and poor self-control, are more prevalent in Korean children with SDB.
• Findings highlight the importance of addressing behavioral aspects in pediatric SDB management.
