Key result
Waist-to-height ratio and body shape index outperform BMI as predictors of elevated blood pressure.
Why the study?
Obesity-related elevation in blood pressure increases hypertension risk, but the predictive value of BMI, ABSI, and WHtR for elevated BP is unclear.
Do BMI, ABSI, and WHtR predict elevated blood pressure in young adults?
Cross-Sectional (n=102)
Do BMI, ABSI, and WHtR predict elevated blood pressure in young adults?
Effect estimate: AUC 0.774 for WHtR; AUC 0.766 for ABSI; AUC 0.11 for BMI
p-value: p=0.002 for WHtR; 0.003 for ABSI; 0.589 for BMI
WHtR and ABSI are better predictors of elevated blood pressure than BMI in young adults.
ABSI and WHtR may aid elevated BP screening in young adults; leaves open prospective validation in general populations.
Background: One of the complications of obesity is an elevation in blood pressure which can increase the risk of hypertension. This study aimed to explore body mass index (BMI), a body shape index (ABSI), and waist-to-height ratio (WHtR) in predicting elevated blood pressure (BP).Methods: This study was conducted in a cross-sectional design on 215 medical students from October 2019 to September 2020. Respondents measured their own weight, height, waist circumference and BP. Receiver operating characteristics (ROC) curve were analyzed using IBM SPSS v.23. Results: Of the 215 medical students who participated in this study, only 102 met the inclusion criteria. The majority of the students were female (n=71, 69.6%) with a mean age of 19.37 years, and normal blood pressure (n=90, 88.2%). Area under the ROC curve (AUC) of WHtR and ABSI were 0.774 (p-value= 0.002) and 0.766 (p-value= 0.003) respectively, which were still acceptable. However, the AUC of BMI (p-value=0.589) was 0.11, which was considered poor.Conclusion: The indicators of obesity can be used as a screening value for increased blood pressure in adults, with BMI being the weakest indicator compared to ABSI and WHtR. Further research is needed to examine ABSI and WHtR indicators as predictor of increased blood pressure in adults.

Winata et al. (2022) conducted a cross-sectional in Elevated blood pressure (n=102). Body mass index (BMI), a body shape index (ABSI), and waist-to-height ratio (WHtR) was evaluated on Elevated blood pressure (AUC 0.774 for WHtR; AUC 0.766 for ABSI; AUC 0.11 for BMI, p=0.002 for WHtR; 0.003 for ABSI; 0.589 for BMI). Waist-to-height ratio (AUC 0.774, P=0.002) and a body shape index (AUC 0.766, P=0.003) were acceptable predictors of elevated blood pressure, whereas body mass index was a poor predictor.
