Describing the relationship between occupational and non-occupational physical activity using objective measurement

Area of Science:

• Occupational health
• Public health
• Exercise science

Background:

• Physical inactivity poses significant health risks for the working population.
• The relationship between physical activity during work hours and outside of work is not fully understood.
• Understanding this interplay is crucial for developing targeted health interventions.

Purpose of the Study:

• To examine the association between occupational physical activity (OPA) and non-occupational physical activity (non-OPA).
• To investigate potential sex differences in the relationship between OPA and non-OPA.
• To analyze activity patterns in 233 working adults in the Minneapolis, MN metro area (2010-2012).

Main Methods:

• Activity levels were measured using accelerometry.
• Occupational physical activity (OPA) and non-occupational physical activity (non-OPA) were differentiated based on self-reported work schedules.
• Regression models were employed to assess the associations.

Main Results:

• A positive association was found between average weekly OPA and non-OPA (B=0.18, 95% CI: 0.08-0.28).
• The association between OPA and non-OPA was significantly stronger in women compared to men (B_interaction = -0.39, 95% CI: -0.61 to -0.17).

Conclusions:

• Findings suggest a consistent pattern of physical activity levels across work and non-work domains.
• Individuals with lower occupational physical activity also exhibit lower non-occupational physical activity.
• Further research into the mechanisms underlying the OPA/non-OPA relationship is warranted.
