Relationship between fat distribution ratio and blood pressure in obese adolescents
Abstract
Background The incidence of obesity in big cities increasessignificantly. The association between obesity and increased risk
of cardiovascular disease and hypertension in adults has been
known but less information is available in adolescents. Similarly,
the relationship between body-fat distribution and cardiovascular
diseases in adolescents is less clear tha that in adults.
Objective This study aimed to determine the association between
body fat distribution and increased blood pressure in obese
adolescents in Bandung.
Methods This cross-sectional study was conducted from June to
August 2006. Subjects were students aged 15-18 years at high
schools in Bandung with body mass index (BMI) measured using
CDC chart 2000 (> P95) and increased blood pressure (> P90)
depended on age and gender according to National High Blood
Pressure Education Program Working Group on High Blood
Pressure in Children and Adolescents 2004. Waist-to-hip ratio
(central fat), and subscapula skinfold-to-triceps skinfold ratio
(peripheral fat) were used to measure fat distribution. Correlation
between body fat distribution and blood pressure was analyzed
using Pearson correlation statistical test.
Results Out of 3170 adolescents examined, 34 obese adolescent
girls and 43 obese adolescent boys had increased blood pressure.
Correlation between waist-to-hip ratio and systole blood pressure
in boys showed by r=0.495; P=0.003 and girls showed r=0.494;
P=O.OOl. Correlation between subscapula skinfold-to-triceps
skinfold ratio in boys showed r=0.289; P=0.097 and girls showed
by r=0.248; P=0.109.
Conclusion Central fat is moderately correlated with increased
blood pressure in obese adolescents.
