About

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.

Inclusion and exclusion criteria

Inclusion Criteria

Men and women aged 35 years or older with increased cardiometabolic risk, defined by all of the following:

1. Clinically confirmed hypertension, with or without antihypertensive treatment, as documented in the Electronic Health Record (EHR).

2. Overweight or obesity, defined as BMI between 27 and 40.

3. Physically inactive lifestyle, defined as either:

   • Light intensity or inactive category on the Stanford Brief Activity Survey (SBAS), or
   • Light intensity or inactive category in the physical activity section of the Swedish National Board of Health and Welfare Lifestyle Questionnaire.

Exclusion Criteria

Medical contraindications to physical activity (based on FYSS 2021, p. 182):

• Severe, symptomatic aortic stenosis
• Acute pulmonary embolism, myocarditis, pericarditis, or systemic infection (e.g., fever, muscle pain, lymphadenopathy)
• Suspected or known aortic dissection
• Severe hypertension (Grade 3: SBP >180 mmHg or DBP >110 mmHg), regardless of symptoms
• Unstable coronary artery disease (including unstable angina, suboptimally treated stable angina, or recent myocardial infarction <8 weeks)
• Symptomatic, uncontrolled arrhythmia
• Symptomatic, uncontrolled heart failure

Other exclusion criteria:

• Implanted pacemaker or ICD
• Pregnancy

• Inability to walk stairs

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Double Blind

---

450 participants in 3 patient groups

Stair and brisk walking combined

Experimental group

Description:

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.

Treatment:

Behavioral: Stair and brisk walking combined

Brisk walking

Experimental group

Description:

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

Treatment:

Behavioral: Brisk walking

Standard care

Active Comparator group

Description:

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.

Treatment:

Behavioral: Standard care
