Theory-driven, web-based, computer-tailored advice to reduce and interrupt sitting at work: development, feasibility...

Area of Science:

• Occupational Health
• Behavioral Science
• Digital Health Interventions

Background:

• Workplace sitting is a significant contributor to adult sedentary time and adverse health effects.
• Computer-tailored interventions show promise for behavior change but are underutilized for reducing workplace sitting.
• There is a need for effective strategies to mitigate the health risks associated with prolonged occupational sitting.

Purpose of the Study:

• To develop a theory-driven, web-based, computer-tailored intervention to reduce workplace sitting.
• To assess the feasibility of reaching employees with this digital intervention.
• To evaluate the acceptability and initial impact of the tailored advice on employee sitting behavior.

Main Methods:

• A cohort of 179 employees from a public city service were invited to participate.
• An online, computer-tailored advice program based on behavior change theories was developed.
• Logistic regressions analyzed characteristics of participants, and an online questionnaire assessed acceptability and reported behavior changes.

Main Results:

• Employees with higher education and part-time employment were more likely to request the intervention.
• The majority of participants found the advice interesting, relevant, and motivating, though practicality was rated lower.
• Over 58% reported interrupting sitting, and 14% reported reducing sitting time, with many more intending to do so.

Conclusions:

• The web-based intervention is a feasible and acceptable tool for reducing workplace sitting.
• Targeted outreach is needed to engage lower-educated and full-time employees.
• Further randomized controlled trials are recommended to rigorously evaluate the intervention's effects on sedentary behavior.
