Key result
Obesity indices are linked to ~24% of the variability in systolic blood pressure.
Why the study?
The association between selected obesity indices and blood pressure in adults was studied to understand their predictive value for systolic and diastolic blood pressure.
Do obesity indices predict systolic and diastolic blood pressure in adults?

Do obesity indices predict systolic and diastolic blood pressure in adults?
Obesity indices, particularly Abdominal Volume Index and Body Roundness Index, are significantly correlated with systolic and diastolic blood pressure in adults.
Obesity indices link to BP variability in Jordanian adults; leaves open causality, prediction, and broader applicability.
AIMS: To study the association between selected obesity indices, systolic blood pressure (SBP), and diastolic blood pressure (DBP). METHODS: A cross-sectional study on 491 Jordanian adults (19-65 years old). The sociodemographic data, anthropometrics, and blood pressure were measured and recorded. Obesity indices (Conicity Index (CI), Abdominal volume index (AVI), Body Roundness Index (BRI), and Weight-adjusted-waist index (WWI)) were calculated using standard validated formulas. RESULTS: Based on age, the SBP had a significant moderate correlation with BRI and AVI in all age groups. In the age group 20 to 34 years, SBP had a significantly moderate correlation with CI, and DBP had a significantly moderate correlation with BRI and AVI. In the age group 35 to 44 years, DBP had a significantly moderate correlation with CI, BRI, WWI, and AVI. For the age group 45 to 65 years, the SBP had a significantly moderate correlation with all the obesity indexes, opposite to DBP. Obesity indices explain 23.6% to 24.1% of the changeability in SBP, and one unit increase in them resulted in an increase in SBP range from 0.61 ± 0.14 to 19.88 ± 4.45. For DBP, obesity indices explained 15.9% to 16.3% of the variability in DBP, and raising them by one unit led to an increase in the DBP range from 0.27 ± 0.11 to 10.08 ± 4.83. CONCLUSION: All the studied obesity indices impacted SBP and DBP with the highest reported effect for AVI and BRI and a lower impact for WWI. The impact of obesity indices on DBP was affected by age group.

Alkhatib et al. (2023) reported a cross-sectional. Obesity indices (Conicity Index, Abdominal volume index, Body Roundness Index, Weight-adjusted-waist index) was evaluated on Systolic and diastolic blood pressure. Obesity indices explained 23.6% to 24.1% of the variability in systolic blood pressure and 15.9% to 16.3% in diastolic blood pressure among Jordanian adults.
