[Relationship between the polysomnography and body mass index in children].

ABSTRACT

OBJECTIVE: To study the effect of the obstructive sleep apnea hypopnea syndrome on children's growth and to discuss operative standards. METHOD: Five hundred and eighty-two children who were 2.5 to 10 years old were monitored with polysomnography(PSG). The index included apnea and hypopnea index (AHI) and computed body mass index (BMI) which was measured with heights and weights. RESULT: Comparing with the normal children in the same age period and the same sex, boys' BMI had distinguished differences (P < 0.01) when AHI > or =2 and girls BMI had distinguished differences (P < 0.01) when AHI > or =1. CONCLUSION: We Suggests to define the diagnosis and operative standards of pediatric obstructive sleep apnea hypopnea syndrome at AHI > or =2.
