What question did this study set out to answer?

To establish home-based self-measured blood pressure reference values corresponding to standard clinic thresholds for normotension (130/85 mmHg) and hypertension (140/90 mmHg).

Why the study?

What are the home blood pressure thresholds that correspond to clinic blood pressure thresholds for hypertension and normality in adults without known hypertension?

Population

989 adults without known hypertension, mean age 44.3 years, 50.4% female.

Implication

Suggests lower home BP thresholds than guidelines; leaves open outcome validation before any practice change.

Key Points

To establish home-based self-measured blood pressure reference values corresponding to standard clinic thresholds for normotension (130/85 mmHg) and hypertension (140/90 mmHg).
Randomly selected, age- and sex-stratified sample of 1,411 adults attended clinic visits where trained nurses performed clinic BP measurements and instructed participants on home monitoring.
Participants obtained 12 home blood pressure readings across a single day using a calibrated electronic device (Omron 705CP).
Known hypertensives were excluded, leaving 989 normotensive participants (mean age 44.3 years, 50.4% female) for linear regression and percentile-based correlation analyses.
Clinic BP was significantly higher than home BP across age and gender, showing strong correlations for systolic BP (r=0.84) and diastolic BP (r=0.77).
Linear regression mapped the clinic hypertension cutoff (140/90 mmHg) to a home threshold of 131/82 mmHg, and clinic normality (130/85 mmHg) to 123/78 mmHg.
Percentile analysis determined corresponding home thresholds of 134/85 mmHg for hypertension and 124/80 mmHg for normality, both below the standard 135/85 mmHg cutoff.

Structured PICO

What are the home blood pressure thresholds that correspond to clinic blood pressure thresholds for hypertension and normality in adults without known hypertension?

Population

989 adults without known hypertension (from an initial random sample of 1411), mean age 44.3 years, 50.4% female.

Intervention

Home-based self-measurement of blood pressure (12 values in a single day using Omron 705CP electronic device)

Comparator

Clinic-based sphygmomanometer measurements performed by a trained nurse

Outcome

Home BP levels corresponding to clinic BP thresholds of 140/90 mmHg (hypertension) and 130/85 mmHg (normality)surrogate

Home blood pressure thresholds for defining hypertension may be lower (131/82 mmHg) than currently accepted values (135/85 mmHg) when correlated with clinic measurements.

Limitations

Long-term studies are necessary to confirm these results
