Correlation between obesity-related indices and hypertension

Objectives: To explore the correlation between obesity-related indices and hypertension, as well as their predictive ability for hypertension, to provide new insights for the prevention and treatment of the disease. Methods: This retrospective study included participants aged over 18 years from Chongqing General Hospital, spanning January 2023 to January 2024. Based on the presence or absence of hypertension, 160 participants were divided into two groups: an observation group (with hypertension, n=83) and a control group (without hypertension, n=77). Demographic and obesity-related indices were collected to assess their correlation with hypertension. Results: The mean waist circumference (WC) was significantly higher in the observation group 82.46 (78.87-84.35) compared to the control group 82.64 (78.00-84.87), albeit with a typographical error in reporting (P=0.012). The mean A Body Shape Index (ABSI) was significantly higher in the observation group 0.778 (0.078-0.081) compared to the control group 0.076 (0.083-0.087) (P=0.004). The mean body roundness index (BRI) was also significantly higher in the observation group 3.38 (3.07-3.84) than in the control group 3.40 (2.98-3.87) (P=0.02). Logistic regression revealed ABSI (OR=1.15, 95% CI 1.06-1.28, P=0.014), BRI (OR=1.14, 95% CI 1.03-1.23, P=0.048), and WC/BRI (OR=1.13, 95% CI 1.04-1.34, P=0.031) as statistically significant risk factors. The area under the curve values for ABSI, BRI, WC/BRI, and their combination were 0.572, 0.629, 0.652, and 0.731, respectively. Conclusion: ABSI, BRI, and WC/ BRI may serve as independent risk factors for hypertension. These indices, individually or combined, could aid in predicting the risk of hypertension.
