The report from our centre also showed that snoring children without obstructive sleep apnoea had higher blood pressure but not hypertension and decreased arterial distensibility compared with ...controls. 4 The study quoted by Kotagal to support the use of comprehensive clinical assessment to diagnose childhood obstructive sleep apnoea included a sample of 41 children.
Introduction: Obstructive sleep apnea syndrome (OSAS) is a known risk factor for hypertension in adults. This relationship is less clear
in childhood OSAS.
Objective: This study examined the ...relationship between OSAS and 24-h ambulatory BP (ABP), a more accurate assessment than casual BP,
in children with snoring.
Methods: Snoring children aged 6 to 15 years who underwent polysomnography in the sleep laboratory were recruited.
Measurement: Twenty-fourâhour ABP monitoring was initiated a few hours before polysomnography. The children were classified into two groups:
a high apnea-hypopnea index (AHI) group (obstructive AHI > 5/h), and a low-AHI group (AHI ⤠5/h). Mean sleep, wake, and 24-h
systolic BP (SBP) and diastolic BP (DBP) were recorded. A child was considered a ânondipperâ if his or her mean SBP and DBP
did not decrease by ⥠10% during sleep.
Results: Ninety-six children (mean age ± SD, 9.4 ± 2.8 years) were recruited. Forty-one children were obese. When awake, the high-AHI
group children had a significantly higher SBP. When asleep, both SBP and DBP were higher in the high-AHI group. Age, body
mass index (BMI) z score, and desaturation index (DI) were significant predictors for elevated sleep DBP. BMI z score was
the only significant predictor for wake and sleep SBP. Sixteen children (17%) had hypertension, and all were nondippers. Obese
children in the high-AHI group had a significantly higher prevalence of hypertension than obese children in the low-AHI group.
This relationship was not found in nonobese children.
Conclusion: The current study shows that increased DI contributed to the elevation of sleep DBP elevation.

Journal Article
Obstructive sleep apnea syndrome (OSAS) is a known risk factor for hypertension in adults. This relationship is less clear in childhood OSAS.
This study examined the relationship between OSAS and ...24-h ambulatory BP (ABP), a more accurate assessment than casual BP, in children with snoring.
Snoring children aged 6 to 15 years who underwent polysomnography in the sleep laboratory were recruited.
Twenty-four–hour ABP monitoring was initiated a few hours before polysomnography. The children were classified into two groups: a high apnea-hypopnea index (AHI) group (obstructive AHI > 5/h), and a low-AHI group (AHI ≤ 5/h). Mean sleep, wake, and 24-h systolic BP (SBP) and diastolic BP (DBP) were recorded. A child was considered a “nondipper” if his or her mean SBP and DBP did not decrease by ≥ 10% during sleep.
Ninety-six children (mean age ± SD, 9.4 ± 2.8 years) were recruited. Forty-one children were obese. When awake, the high-AHI group children had a significantly higher SBP. When asleep, both SBP and DBP were higher in the high-AHI group. Age, body mass index (BMI) z score, and desaturation index (DI) were significant predictors for elevated sleep DBP. BMI z score was the only significant predictor for wake and sleep SBP. Sixteen children (17%) had hypertension, and all were nondippers. Obese children in the high-AHI group had a significantly higher prevalence of hypertension than obese children in the low-AHI group. This relationship was not found in nonobese children.
The current study shows that increased DI contributed to the elevation of sleep DBP elevation.
