Summary
The ASUKI Step intervention encouraged university employees to walk 10,000 steps daily, aiming to reduce inactivity and assess factors influencing success. This pedometer-based program evaluated changes in health and fitness.
Area of Science:
- Occupational Health
- Behavioral Science
- Public Health Interventions
Background:
- A 9-month pedometer-based worksite intervention, "ASUKI Step," was conducted at Karolinska Institutet (KI) and Arizona State University (ASU).
- The intervention utilized social support theory and a quasi-experimental design.
Purpose of the Study:
- To increase daily step counts among university employees to 10,000 steps.
- To reduce the number of inactive days (less than 3,000 steps).
- To identify determinants of success and evaluate health/fitness changes.
Main Methods:
- 2,118 faculty, staff, and graduate students participated in teams.
- Participants aimed for 10,000 steps daily for six months, with a 3-month follow-up.
- Data collected via website, questionnaires, and physical fitness testing for a subsample.
Main Results:
- Study aimed for 400 participants/site to reach 10,000 steps on 100 days.
- Targeted 70% of participants/site to have ≤2 inactive days per week.
- Evaluated socio-demographic, psychosocial, environmental, and health correlates of success.
Conclusions:
- "ASUKI Step" aimed to increase daily walking and decrease inactivity among university employees.
- The study assessed intra- and interpersonal factors influencing intervention success.
- Changes in physical fitness and body composition were evaluated in a subsample.
