Abstract
Objectives: To study the association of waist-to-height ratio
(WHtR) and elevated blood pressure (BP) in children.
Study design: Cross-sectional study.
Setting: Six elementary schools in Taipei, Taiwan.
Participants: All children aged 7 years at first grade.
Methods: We measured anthropometrics and BP during the
regular health examinations among children.
Main Outcome Measures: Elevated BP in children was defined
as an average systolic BP or diastolic BP greater than or equal to
the gender, age, and height-percentile-specific 95th percentile BP
value.
Results: Among 2,334 eligible school children, the averages of
systolic BP and diastolic BP increased with quartiles of WHtR.
The prevalence of elevated BP in children among the first quartile
of WHtR was 8.8% and increased to 31.2% among the fourth
quartile of WHtR (P < 0.0001). Children among the first quartile of
WHtR being reference, the adjusted odds ratio of elevated BP for
children among the fourth quartile of WHtR was 3.10. The odds
ratio of elevated BP with per 0.01 increase of WHtR was 1.11.
Conclusions: WHtR, simple to measure, is an important factor
associated with elevated BP in children.
