Transportation-related physical activity is associated with lower odds of sleep disorders, while occupation-related physical activity is associated with higher odds in U.S. adults

In a cross-sectional study of 25,732 U.S. adults from NHANES 2007-2018, transportation-related physical activity (TPA) was associated with 21% lower odds of sleep disorders (OR 0.79, 95% CI 0.67-0.93), while occupation-related physical activity (OPA) was associated with 15% higher odds (OR 1.15, 95% CI 1.02-1.30). Total physical activity and leisure-time physical activity showed no significant associations with sleep disorders.

Study 1. Association of Domain-Specific Physical Activity with Sleep Disorders in U.S. Adults: A Cross-Sectional Study Based on NHANES.

observational

Wang R, Zhang T, Zhou C, Battaglini CL, Jiang T · Healthcare (Basel, Switzerland) (2026)

Participants: N/A
Duration: Cross-sectional (2007-2018 cycles)
Intervention: Physical activity domains (occupation-related, transportation-related, leisure-time) assessed via Global Physical Activity Questionnaire
Outcome: Sleep disorders (self-reported or doctor-diagnosed)
Effect Size: OR 0.79 for TPA, OR 1.15 for OPA
Population: U.S. adults (mean age 49.72 years, 12,692 male, 13,040 female) from NHANES 2007-2018

Mechanism Graph

Active commuting (TPA) may improve sleep through increased physical activity and reduced sedentary time
↓
Occupational physical activity (OPA) may involve repetitive movements, heavy lifting, and inadequate recovery, leading to physical strain
↓
OPA may be associated with lower socioeconomic status and work-related stress, negatively impacting sleep
↓
Result: TPA reduces sleep disorder risk, OPA increases risk

Limitations

  • ⚠Cross-sectional design cannot establish causality
  • ⚠Physical activity and sleep disorders were self-reported, subject to recall bias
  • ⚠Potential residual confounding from unmeasured variables
  • ⚠GPAQ may not capture all aspects of physical activity intensity and duration

Frequently Asked Questions

What is the 'physical activity paradox' in sleep health?▼

The paradox refers to the finding that leisure-time physical activity (LTPA) and transportation-related physical activity (TPA) are beneficial for health, but occupation-related physical activity (OPA) may be harmful. In this study, TPA was associated with lower odds of sleep disorders, while OPA was associated with higher odds.

Does total physical activity affect sleep disorders?▼

No, total physical activity was not significantly associated with sleep disorders (OR 1.01, 95% CI 0.89-1.13, p=0.912). The effect depends on the domain of physical activity.

Is leisure-time physical activity (like exercise) associated with better sleep?▼

In this study, LTPA was not significantly associated with sleep disorders (OR 0.96, 95% CI 0.85-1.09, p=0.511). However, the restricted cubic spline analysis suggested a nonlinear relationship, so moderate LTPA might still be beneficial.

What type of physical activity is best for preventing sleep disorders?▼

Transportation-related physical activity, such as walking or cycling to work, was associated with a 21% lower odds of sleep disorders. In contrast, occupation-related physical activity was associated with a 15% higher odds.
