Longitudinal Relationship Between Sitting Time on a Working Day and Vitality, Work Performance, Presenteeism, and...

Area of Science:

• Occupational Health
• Behavioral Science

Background:

• Prolonged sitting time is prevalent in modern workplaces.
• Sedentary behavior is associated with various health risks.
• Understanding the impact of sitting time on work-related outcomes is crucial.

Purpose of the Study:

• To investigate the longitudinal relationship between sitting time during working days and key work-related outcomes.
• To examine associations with vitality, work performance, presenteeism, and sickness absence over time.

Main Methods:

• A five-month workplace intervention program was implemented.
• Sitting time and work outcomes were measured at baseline, post-intervention, and 10 months later.
• Generalized linear mixed models analyzed longitudinal relationships and interaction effects.

Main Results:

• A significant and sustained reduction in daily sitting time was achieved.
• Decreased sitting time was significantly associated with higher vitality scores.
• The observed association between reduced sitting time and vitality was marginal (b=-0.0006, P=0.000).

Conclusions:

• Significant, albeit marginal, associations exist between sitting time and important work-related outcomes.
• Findings support the need for further investigation into the impact of reducing sedentary behavior in the workplace.
