A new study highlighted by the American Heart Association, explains the potential issue with home blood pressure monitoring: inaccurate readings due to improper cuff size. Researchers found that standard cuffs on popular devices may not fit a significant portion of the population, particularly black adults. The findings were presented recently at the American Heart Association Hypertension Scientific Sessions in Chicago and published in the journal Hypertension.
Nearly 7% of US adults (17.3 million) have arm circumferences outside the standard cuff size offered by most devices (8.7 inches to 16.5 inches). Black adults are disproportionately affected, with nearly 12% having an incompatible arm size compared to 7% of white adults and 5% of Hispanic adults. Cuffs that are too small can overestimate blood pressure, while cuffs that are too large can underestimate blood pressure. Inaccurate readings can lead to missed diagnoses or improper treatment decisions.
To address this issue, manufacturers should offer a wider range of cuff sizes, consumers should ensure they have the correct cuff size for their arm circumference, and healthcare providers should educate patients about proper cuff size selection. Additionally, using validated home blood pressure monitors is recommended. This study highlights the importance of considering diverse body types when designing medical devices and ensuring patients have the tools they need for accurate self-monitoring.

Self-Measured Blood Pressure Monitoring: Self-Measured Blood Pressure Monitoring (SMBP) is the regular measurement of blood pressure by the patient, outside the clinical setting. SMBP requires a home blood pressure measurement device to measure blood pressure at different points throughout the day. Learn how SMBP and support from the health care team can help with blood pressure control.
