Study Overview
Brief Summary
The purpose of this study is to examine the impact and cost effectiveness of a workplace-based intervention aimed at reducing prolonged occupational sitting among office-based workers. The study will be conducted in three phases. Phase I: is an Integrative review on economic evaluations of workplace-based interventions for reducing occupational sitting time. Phase II: is a secondary analysis of register data within the Northern Finland Birth Cohort 1966 (NFBC-1966). This is aimed at evaluating the association between prolonged sitting time with societal and/or organization economic perspective across different occupational categories at midlife. Phase III will be a Randomized Control Trial (RCT) of an office-based intervention designed to reduce prolonged occupational sitting time. The sample for the RCT will be 140 office-based workers - 70 participants will be enrolled in the control group whilst 70 participants will be enrolled within the intervention group. The study will be conducted from 2021 to 2025. An article-based dissertation will be completed at the end of the study, this will be mainly based on four articles that will be published in international peer reviewed journals.
Detailed Description
In office-based work environments, prolonged durations of sitting are the commonest form of daily sedentary behavior within which the most sitting time (47.2% of total daily sitting time). Sedentary behavior has been associated with up to 1.5 ¬3% of the total direct health, about US$ 13.7 billion incurred in production loss costs, and 13.4 million due to disability-adjusted life years globally. In Finland, physical inactivity and sedentary behavior resulted in a total healthcare cost of €3.2 billion due to low physical activity and €1.5 billion due to high sedentary behavior. Sustaining healthy and productive workers is a substantial goal of the European labor policy thus, there is need for workplace-based interventions to promote healthy sitting at workplaces.

Outcomes
Primary Outcomes
Physical activity
Time Frame: Assessments will be done at baseline, 3 months, 6 months, and 12 months. Data from activity monitoring, and a self-administered questionnaires will be used.
Physical activity will be objectively measured with the ActivePal accelerometer (PAL technologies LTD, Glasgow, UK). This is a thigh-worn, tri-axial accelerometer. The accelerometer was chosen because it is easy to use, discrete and can differentiate between sitting, standing, and stepping in varying postural transitions. Participants will be asked to wear the monitors for at least 14 days during workdays hours. The participants will then give the accelerometer to the researcher, data recorded on them will be downloaded and analyses.
Secondary Outcomes
- Cost(Assessments will be done at baseline, 3 months, 6 months, and 12 months)
- Presenteeism(Assessments will be done at baseline, 3 months, 6 months, and 12 months)
- Health related quality of life(Assessments will be done at baseline, 3 months, 6 months, and 12 months)
- Absenteeism(Assessments will be done at baseline, 3 months, 6 months, and 12 months)
