Should not yet change practice; leaves open waist circumference as an independent BP marker in normal-BMI children.
Cross-Sectional (n=3,417)
Is increased waist circumference associated with elevated blood pressure in children aged 6 to 11 years with normal BMI?
Effect estimate: OR 1.57 (95% CI 1.14 - 2.17)
Absolute Event Rate: 12.1% vs 8.1%
Increased waist circumference is associated with elevated blood pressure in children with normal BMI, suggesting it may be a useful cardiovascular risk marker even in non-obese children.
Pazin et al. (2017) conducted a cross-sectional in Normal body mass index (n=3,417). Highest waist circumference quartile (Q4) vs. Lowest waist circumference quartile (Q1) was evaluated on Elevated blood pressure (≥ 90th percentile) (OR 1.57, 95% CI 1.14 - 2.17). Being in the highest waist circumference quartile was associated with a 57% higher likelihood of elevated blood pressure compared to the lowest quartile in children with normal BMI (OR 1.57; 95% CI 1.14-2.17).
