Insights
Pediatric hypertension without obstructive sleep apnea (OSA) is linked to factors like birth weight, BMI, and certain medical conditions. Identifying these associations is crucial for early intervention and risk mitigation in children.
Area of Science:
- Pediatric Cardiology
- Sleep Medicine
- Public Health
Background:
- Obstructive sleep apnea (OSA) is a known risk factor for hypertension in adults.
- The association between hypertension and pediatric patients without OSA is less understood.
- This study focuses on identifying factors contributing to hypertension in children diagnosed without OSA.
Purpose of the Study:
- To identify factors associated with pediatric hypertension in children without obstructive sleep apnea (OSA).
- To analyze demographic, anthropometric, social, and medical history data in relation to hypertension.
- To investigate correlations between polysomnography findings and hypertension in this specific pediatric cohort.
Main Methods:
- Retrospective chart review of 285 pediatric patients (8-17 years) who underwent polysomnography.
- Hypertension defined as BP ≥95th percentile for age, sex, and height per AAP guidelines.
- Statistical analysis included Chi-square and Wilcoxon rank sum tests (p < 0.05 significance).
Main Results:
- Of 137 non-OSA patients, hypertension was associated with parents in household, smoking exposure, and food allergies.
- Significant correlations found between hypertension and birth weight, BMI, daytime heart rate, systolic BP, and diastolic BP.
- Mental, neurological, and respiratory diseases showed significant differences; only nighttime heart rate was significant in PSG parameters.
Conclusions:
- Pediatric hypertension without OSA is multifactorial, involving various clinical and demographic factors.
- Associated co-morbidities and identified risk factors require further clinical attention.
- Early identification and management of these factors can help mitigate hypertension risks in children.
Abstract:
Background/Objectives: The relationship between OSA and adult hypertension has been extensively studied; however, it remains understudied in pediatric patients without OSA. The aim of this study is to identify factors associated with pediatric hypertension without OSA, through an IRB-approved retrospective chart review of patients who underwent polysomnography at Nemours Children's Hospital, DE/NJ between January 2020 and July 2023. Methods: Eligibility criteria included children 8-17 years, completed PSG, and clinic visit blood pressure (BP). Anthropometrics, demographics, social determinants, and medical history were obtained from electronic medical records. Hypertension was defined as the average systolic and/or diastolic BP that is ≥95th percentile for gender, age, and height based on AAP Clinical Practice Guidelines. All variables were checked for normality. Chi-square tests for categorical data and Wilcoxon rank sum tests for continuous data were used to test significance between non-OSA non-hypertensives (NH) and hypertensives (H). p < 0.05 is considered significant. Results: Of 285 charts evaluated, 137 were classified as non-OSA. Patient information, including parents in household, smoking exposure, and food allergies, were statistically significant (p < 0.05) in hypertensive pediatric patients without OSA. Hypertension was significantly correlated (p < 0.05) with birth weight, BMI, daytime heart rate, systolic BP, and diastolic BP. Statistically significant differences (p < 0.05) were found in mental illnesses, neurological disease, and respiratory disease. Among polysomnography parameters, only nighttime heart rate was found to be statistically significant. Conclusions: The data suggests that in pediatric patients without OSA, there are multiple factors and co-morbidities associated with hypertension. These factors and co-morbidities warrant additional follow up in clinical practice to mitigate the risks of hypertension in pediatric patients.
