Occupation, hours worked, and leisure-time physical activity.

Area of Science:

• Occupational Health
• Public Health
• Physical Activity Research

Background:

• International research consistently shows lower leisure-time physical activity (LTPA) rates among blue-collar employees.
• Commonly cited barriers include lack of time and demanding work schedules.
• The mediating role of time spent at work in the occupation-LTPA relationship remains unclear.

Purpose of the Study:

• To investigate the association between occupation type, hours worked, and participation in LTPA.
• To determine if time spent in paid employment explains occupational differences in LTPA.

Main Methods:

• Secondary analysis of the 1995 Australian Health Survey (n=24,454 employed adults aged 18-64).
• Occupations categorized as professional, white-collar, or blue-collar.
• LTPA assessed as sufficient or insufficient based on recommended energy expenditure; logistic regression used to analyze relationships, controlling for covariates.

Main Results:

• Individuals in blue-collar occupations were approximately 50% more likely to have insufficient LTPA.
• This occupational disparity in LTPA was not explained by the number of hours worked.
• A complex, gender-specific relationship between hours worked and LTPA was observed but difficult to interpret.

Conclusions:

• Occupational differences in LTPA are not accounted for by variations in hours worked.
• Further research is needed to explore other work-related factors acting as barriers to physical activity.
• Understanding these factors is crucial for developing targeted health promotion strategies to reduce sedentary behavior and health inequalities.
