Why the study?

While elevated blood pressure prevalence declined in US youth, trends in blood pressure levels among Korean children and adolescents had not been analyzed.

Population

7804 Korean children and adolescents aged 10-18 years

Comparison

Trends across 3 time periods: 2007-2009 vs 2010-2012 vs 2013-2015

Design

National survey-based repeated cross-sectional study

Implication

Rising BP trends in Korean youth warrant surveillance; leaves open drivers beyond BMI and need for prospective confirmation.

Key Points

To determine recent secular trends in blood pressure levels, elevated blood pressure, and hypertension among Korean children and adolescents between 2007 and 2015.
Analyzed data from 7,804 Korean children and adolescents aged 10–18 years across three survey cycles (2007–2009, 2010–2012, and 2013–2015) in the Korea National Health and Nutrition Examination Survey.
Categorized elevated blood pressure (>90th percentile) and hypertension (≥95th percentile) using 2017 American Academy of Pediatrics sex-, age-, and height-specific standards.
Mean systolic blood pressure increased by 3.9 mm Hg from 2007–2009 to 2013–2015, with no significant change in diastolic blood pressure, accompanied by significant increases in BMI z-scores.
In 2013–2015, prevalence rates were 8.8% for elevated blood pressure and 9.0% for hypertension overall, with hypertension prevalence reaching 27.7% in the obese subgroup.
Elevated blood pressure was associated with sex, age, BMI z-score, and survey period, while hypertension was associated with sex, age, and BMI z-score.

Structured PICO

Population

7,804 Korean children and adolescents aged 10-18 years from the Korea National Health and Nutrition Examination Survey (2007-2015)

Outcome

Trends in blood pressure levels, and prevalence of elevated blood pressure and hypertension over 3 time periods (2007-2009, 2010-2012, and 2013-2015)surrogate

The prevalence of hypertension and mean systolic blood pressure have increased among Korean children and adolescents from 2007 to 2015, likely driven by increasing obesity rates.
