Background

Worldwide pediatric hypertension (HTN) prevalence is increasing. Pediatric HTN predicts adulthood HTN, the modifiable leading factor of cardiovascular disease (CVD). Therefore, pediatric HTN is important for CVD risk prevention. There are two well-known pediatric HTN guidelines, the 2017 American Academy of Pediatrics (AAP) and the 2016 European Society for Hypertension (ESH). Also, Korea Center for Disease Control established the blood pressure (BP) classification in 2008 (K-CDC). There is discordance of HTN prevalence in each BP classification. However, no study evaluated the CVD risk according to each BP criteria in the Korean pediatric population. This study evaluated the difference in prevalence and pediatric CVD risk factors according to each BP criteria.

Methods

The data of 2060 children and adolescents aged 10-18 years from the Korea National Health and Nutrition Examination Survey 2016-2018 was reviewed. The BP was classified by AAP, ESH, K-CDC and modified AAP (K-AAP, applying the normal weight Korean children BP reference table in AAP definition). The high BP was defined when BP was above normotension. To analyze the difference in CVD risk, AAP and ESH, AAP and K-AAP, and K-AAP and K-CDC were compared. In each comparison, those newly defined as high BP are compared to those with consistent normotensive - age, sex, height matched. Finally, the BP criteria reflecting more CVD risk was used to analyze data from Korea School Health Examination Survey 2018.

Results

The prevalence of high BP in Korean children and adolescents was generally high in AAP than ESH (19.5% vs 10.6%, p<0.0001). However, there were some differences in prevalence according to age, sex and obesity. AAP reflected more CVD risk factors, including obesity and metabolic risk, than ESH. K-AAP well-screened non-obese children with metabolic risk than AAP and children with obesity and metabolic risks than K-CDC. The prevalence of high BP and HTN in Korean school students with K-AAP was 13.7% and 5.1%, respectively.

Conclusion

The K-AAP classifies Korean children and adolescent with more CVD risk factors as high BP. Therefore, for early CVD risk control, K-AAP could be used to define pediatric HTN in Korea. Further study is warranted for actual CVD association.
