Abstract

Objective: To examine the association between obesity and high blood pressure (BP) in Chinese children and adolescents.

Methods: Body mass index (BMI) and blood pressure measurements of 197 191 children aged 7-17 years were obtained from a Chinese national survey in 2010. Obesity and high BP were defined according to the reference values for Chinese children. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) of different BMI categories for high BP, as well as the population attributable risk percent (PAR%), were also calculated.

Results: The prevalence of high BP was 16.1% for boys and 12.9% for girls in 2010. Overweight and obese children had a significantly higher prevalence of high BP than non-overweight children in both boys and girls in each age group. ORs (95% CI) for high BP were 4.1 (3.9, 4.4) in obese boys and 4.0 (3.7, 4.3) in obese girls. The overall PAR% for high BP due to overweight and obesity was 14.4%.

Conclusion:
Overweight and obese children have a significantly higher risk of high BP than non-overweight children. Eliminating overweight and obesity could reduce 14.4% of high BP cases.
