In Korean adolescents, body mass index correlated better with blood pressure than waist circumference and was independently associated with high blood pressure even after adjusting for waist circumference.

Does BMI correlate better with blood pressure than waist circumference in adolescents?
In Korean adolescents, BMI is a better indicator of blood pressure levels than waist circumference, even in normal-weight individuals.

PURPOSE: Overweight can be defined by the body mass index (BMI) and is likely associated with an increased cardiovascular disease risk. However, waist circumference (WC), a central adiposity index, may be a better indicator of cardiovascular disease risk. Studies comparing the effects of BMI and WC on cardiovascular risk factors, such as high blood pressure (BP), are rare in adolescents. METHODS: We analyzed the correlations of BMI and WC with BP in 3,363 Korean adolescents (aged 10-19 years), using data from the Korean National Health and Nutrition Examination Surveys (2009-2011). RESULTS: Systolic BP (SBP) in both sexes and diastolic BP (DBP) in boys were higher in the high BMI (>85th percentile) and high WC (>90th percentile) groups. High BMI and high WC were positively correlated with high SBP (>90th percentile) in both sexes, and high DBP (>90th percentile), in boys. BMI maintained its positive associations with SBP, DBP, high SBP, and high DBP in the normal weight (BMI≤85th percentile) and overweight (BMI>85th percentile) groups in both boys and girls, as well as in all subjects of both sexes, even after adjustment for WC. However, WC did not correlate with SBP, DBP, high SBP, or high DBP after adjustment for BMI in any group in either sex. CONCLUSION: In Korean adolescents, BMI correlated better with BP and high BP levels than WC. Further, BMI was positively associated with BP and high BP in the normal weight group as well as in the overweight group.
Young Hwan Song (Wed,) conducted a cross-sectional in Normal weight and overweight adolescents (n=3,363). High body mass index (>85th percentile) vs. Normal body mass index (≤85th percentile) was evaluated on High systolic blood pressure (>90th percentile) in boys (OR 3.05, 95% CI 2.18-4.26, p=<0.001). In Korean adolescents, body mass index correlated better with blood pressure than waist circumference and was independently associated with high blood pressure even after adjusting for waist circumference.
