Sleep disturbances and sleep latency are associated with metabolic syndrome in male Taiwanese workers

In a cross-sectional study of 348 Taiwanese workers, sleep disturbances and sleep latency were significant predictors of metabolic syndrome in men, while shift work and BMI were associated in women. The overall prevalence of metabolic syndrome was 26.4%, with higher rates in men (33.3%) than women (19.3%).

Mechanism Graph

Sleep disturbances and prolonged sleep latency may disrupt hormonal regulation
↓
This disruption can increase cortisol and inflammatory markers
↓
These changes promote insulin resistance and central obesity
↓
Result: Elevated risk of metabolic syndrome in men

Limitations

  • ⚠Cross-sectional design prevents causal inference
  • ⚠Self-reported sleep measures may introduce recall bias
  • ⚠Sample limited to Taiwanese workers, reducing generalizability
