Abstract
Background
Patterns of blood pressure (BP) change from early adolescence to young adulthood have not been well-described. The objective of this study was to examine the predictive value of pediatric BP classification on BP change and identify subpopulations with large BP increases during adolescence and early adulthood.
Methods
Baseline data were obtained from medical checkups of Japanese adolescents aged 12–13 years in 2009 or 2010 and subsequent BP values were followed for a 9-year period. Mixed-effects models were used to estimate the effects of baseline factors on subsequent BP changes.
Results
Hypertensive and elevated BP group consistently had higher BP values than normal BP group throughout the observation period. Multivariate mixed-effects model analyses revealed group-by-time interactions between systolic BP change and BP category in males and uric acid category in females, and between diastolic BP change and white blood cell count in males and obesity and high-density lipoprotein cholesterol in females; however, these factors had limited effects on the rate of BP increase, indicating that they are not suitable as clinical predictors of BP increase.
Conclusions
Pediatric BP category predicted BP values, but there was no factor that identified subpopulations with large BP increases in adolescence and early adulthood.
Impact
-
Blood pressure category in the American Academy of Pediatrics clinical practice guideline at age 12–13 years predicted subsequent blood pressure values during adolescence and early adulthood.
-
No baseline factor that identified a subpopulation with large increase in blood pressure during adolescence and early adulthood in clinical practice was found.
-
Our study contributes to the existing literature by demonstrating the usefulness of the American Academy of Pediatrics clinical practice guideline for blood pressure classification in a Japanese population.
