Summary
Job control boosts physical activity in working women, while schedule control reduces it. Educational background influences these associations, highlighting barriers for those with less formal education.
Area of Science:
- Occupational Health
- Public Health
- Sociology of Work
Background:
- Workplace factors significantly influence employee health behaviors.
- Understanding job control and schedule control is crucial for promoting physical activity among women.
- Educational and racial disparities may affect the relationship between work control and physical activity.
Purpose of the Study:
- To examine the influence of job control and schedule control on women's physical activity.
- To investigate how educational attainment and race modify these associations.
- To identify workplace barriers and facilitators for physical activity.
Main Methods:
- Prospective study of 302 working women.
- Validated measures for job control and schedule control.
- Objective assessment of daily steps using activity monitors.
Main Results:
- Higher job control correlated with increased daily steps.
- Greater schedule control was associated with fewer daily steps.
- Educational level moderated the relationship between ethnicity and physical activity.
Conclusions:
- Low job control presents a barrier to physical activity, particularly for women with lower educational attainment.
- Schedule flexibility does not necessarily translate to increased physical activity for women.
- Interventions should consider job control and educational support to promote physical activity.
