Brief Summary

This clinical trial investigates whether incorporating stair walking into daily routines improves physical health in adults at risk of lifestyle-related conditions such as hypertension, type 2 diabetes, and cardiovascular disease. Participants will be randomized into three groups: (1) stair walking combined with brisk walking, (2) brisk walking alone, and (3) a control group receiving standard lifestyle advice without specific exercise instructions, stratified by age (\<65 y/o, v \>=65) and site. The primary objective is to assess whether the combination of stair and brisk walking leads to greater reductions in systolic blood pressure compared to brisk walking alone or standard care. Secondary outcomes include changes in cardiometabolic risk factors. Participants in the stair walking group will be instructed to climb ≥250 steps per day (\~5.5 minutes/day or \~37.5 minutes/week), or complete an equivalent elevation via inclined slopes, along with ≥75 minutes of brisk walking per week. Those in the brisk walking group will walk ≥150 minutes per week. The control group will receive general lifestyle advice but no tailored physical activity goals or feedback. Participants in both active groups will aim to double their baseline activity levels. Physical activity will be continuously monitored using wearable devices. The active groups will receive personalized feedback and motivational support throughout the 6-month intervention period. If effective, this study may offer a simple, scalable, and low-cost intervention model for use in clinical and public health settings, emphasizing personalized goals, remote monitoring, and behavioral support.

Outcome Measures

Primary Outcomes (1)

  • Systolic Blood Pressure (SBP) at 6 months

    Office systolic blood pressure (SBP) at 6-month follow-up, adjusted for baseline values. SBP is a validated and widely accepted surrogate marker for cardiovascular morbidity and mortality, as well as overall health risk.

    6 months

Secondary Outcomes (5)

  • Diastolic Blood Pressure (DBP)

    6 months

  • HOMA-index

  • HbA1c

  • LDL cholesterol

  • Triglycerides

Study Arms (3)

Stair and brisk walking combined

EXPERIMENTAL

Participants will double their baseline physical activity levels by combining stair walking and brisk walking. The stair walking goal is ≥250 steps per day (equivalent to \~37.5-45 meters elevation or 15 floor levels), totaling \~37.5 minutes per week. In addition, they will complete ≥75 minutes of brisk walking per week.

Behavioral: Stair and brisk walking combined

Brisk walking

EXPERIMENTAL

Participants will double their baseline physical activity levels by engaging in brisk walking only, with a minimum target of \>150 minutes per week.

Behavioral: Brisk walking

Standard care

ACTIVE COMPARATOR

Participants will receive general lifestyle advice aligned with current physical activity guidelines but will not be provided with specific exercise instructions, personalized activity targets, or feedback. They will wear the same activity monitor as the intervention groups, but without access to feedback or goal-setting features.

Behavioral: Standard care

Masking Details
Due to the nature of the intervention, participant blinding is not feasible. To ensure validity, group allocation will be disclosed only after baseline data collection and by personnel not involved in outcome assessments. To preserve assessor blinding at follow-up, participants will be instructed not to reveal their group assignment. Additionally, study staff will document whether blinding was maintained after each follow-up assessment.
