Key result
High relative body fat had little independent impact on systolic blood pressure in children when matched for height and weight, showing a mean difference of only 0.01 mmHg in boys and 0.20 mmHg in girls compared to low body fat.
Why the study?
Does relative body fat independently increase blood pressure in children when matched for overall body size (height and weight)?
Population
38,150 Chinese children aged 7-18 years from the 2005 and 2008 Chinese National Surveys.
Comparison
Highest quartile of body fat vs Lowest quartile of body fat, individually…
Design
Cross-sectional

Does not support targeting body fat independent of size for BP control in children; leaves open adiposity's causal role in longitudinal data.
Cross-Sectional (n=38,150)

Mean Difference: 0.01 (95% CI -0.41–0.44)
Ma et al. (2012) conducted a cross-sectional in Blood pressure (n=38,150). High body fat (highest quartile of skinfold thickness or waist circumference) vs. Low body fat (lowest quartile of skinfold thickness or waist circumference) was evaluated on Difference in systolic blood pressure (SBP) between high- and low-skinfold-thickness groups in boys (MD 0.01 mmHg, 95% CI -0.41 to 0.44). High relative body fat had little independent impact on systolic blood pressure in children when matched for height and weight, showing a mean difference of only 0.01 mmHg in boys and 0.20 mmHg in girls compared to low body fat.
