Commuting distance and behavior-related health: A longitudinal study

Area of Science:

• Public Health
• Epidemiology
• Occupational Health

Background:

• Active commuting and short commute times offer known health benefits.
• Evidence on the health impacts of commuting distance remains limited.
• Understanding commuting distance effects is crucial for public health strategies.

Purpose of the Study:

• To investigate the longitudinal associations between commuting distance and behavior-related health outcomes.
• To examine how different commuting distances impact physical inactivity, overweight, smoking, problem drinking, and sleep quality.
• To identify potential dose-response relationships between commuting distance and health.

Main Methods:

• Longitudinal study using four waves of the Swedish Longitudinal Occupational Survey of Health (2012-2018).
• Included 11,023 individuals and 21,769 observations.
• Analyzed self-reported physical inactivity, overweight, smoking, problem drinking, and disturbed sleep using random effects logistic regression (Generalized Estimating Equations).

Main Results:

• Longer commuting distance was associated with higher odds of physical inactivity (per doubling of distance: OR 1.06) and overweight (OR 1.02).
• Increased odds of disturbed sleep were also observed with longer commutes (OR 1.03).
• Categorized analysis showed higher odds of physical inactivity for longer commutes compared to the shortest (<3.1 km).

Conclusions:

• Shorter commuting distances may be beneficial for behavior-related health.
• Longer commutes are associated with increased risks of physical inactivity, overweight, and disturbed sleep.
• Further research could explore interventions to mitigate negative health effects of long commutes.
