Interventions/Control_1

Workers with a systolic blood pressure of >=140 mmHg and/or a diastolic blood pressure of >=90 mmHg at routine workplace health checkups were allocated to either an intervention group or a control group using stratified randomization based on sex, age, and systolic blood pressure level.

Participants assigned to the intervention group performed home blood pressure monitoring using a smartphone application-connected, communication-enabled blood pressure device twice daily (after waking and before bedtime) for 14 consecutive days, followed by initial lifestyle counseling based on a hypertension management plan using the home blood pressure results; home blood pressure was re-evaluated and additional counseling was provided three months later.

Interventions/Control_2

Participants in the control group did not receive home blood pressure monitoring; instead, they received initial lifestyle counseling based on blood pressure measured at the workplace health checkup according to the hypertension management plan, followed by re-evaluation using casual blood pressure measurement and additional counseling three months later.

Results

In the intervention group, significant reductions were observed in SBP (-7.5 mmHg; 95% CI, 2.0-13.0; p=0.010), DBP (-4.6 mmHg; 95% CI, 0.5-8.6; p=0.028), body weight (-1.2 kg; 95% CI, 0.2-2.2; p=0.021), and HbA1c (-0.1%; 95% CI, 0.02-0.2; p=0.020). No significant changes were observed in the control group. There were no significant between-group differences in waist circumference, lipid profiles, estimated salt intake, or medication use.
